Do-it-yourself prior radiator repair

In detail: do-it-yourself prior radiator repair from a real master for the site my.housecope.com.

Welcome!
The cooling radiator is included in the cooling system, when the engine is running, the coolant runs in a circle and most of it is in the cooling radiator, when driving at speed, the radiator is cooled by the air flow, and therefore the liquid cools down and the engine does not heat up much.

Note!
To change the radiator in the car, you will need: All the keys that are in your arsenal, and you will also need screwdrivers, the containers into which you will drain the coolant (Or one large container) well, and stock up on the new Coolant, because the old one will need to be drained and if it will be in poor condition, it is better after assembly, in the radiator and expansion tank, pour a good fresh liquid!

Summary:

Where is the cooling radiator located?
In the front of the body, it is located, secured with nuts, they attach it to the TV (the TV is the very front part, where the headlights are, it still connects the bumper and side members), it is not very difficult to remove the radiator on the priors, since there is enough space , in order to crawl with your hands, but still, if you stock up on competent keys, then the replacement process will be completed much faster, namely the knob will be very useful and cap heads to it.

When do you need to change the cooling radiator?
If it leaks, then the radiator must be replaced, it is easy to understand this in the summer, but in the winter you just need to pay attention to the coolant, or, more precisely, to its level, if it starts to decrease, then you will already need to check the entire cooling system and find a leak , it is possible to recognize that it is the radiator that is flowing only with the help of ultraviolet best ones (Thanks to them, the coolant is very visible) or by removing it and placing it in a large container with water (Having removed the radiator, you can very accurately determine if there is a hole in it), in front of the room, the radiator will need to be pumped with compressed air through the hole for pouring coolant into the radiator (this hole will not simply need to be immersed in water, or you will not need to plug it well with any other holes, so that 100% air does not come out of them), in more detail like this check to carry out, see the video below:

Video (click to play).

Note!
If the holes in the radiator are not large, then you can not change it at all, but simply solder it carefully and it will be enough for a while, but if you want to put a radiator and, as they say, forget about it, then it is better to buy a new one, because it is usually not sealed. enough for a long time and if a pebble hits this place, the soldering immediately flies off (It depends on how well the radiator is soldered)!

Withdrawal:
1) Before starting work, drain all the coolant from the radiator (How to drain the liquid, read "here") and proceed to removing the electric fan (If you don’t remove it, you simply don’t pull out the radiator), to do this, first discard the negative terminal with the battery, loosening the bolt that secures it for this, then remove the air filter housing because it will interfere very much (Read "here" how to do this), well, you can start removing the electric fan, at the beginning, disconnect the wiring from each other, wiring for the electric fan it goes in the side part in the form of a connector and a shoe (see photo 1), then unscrew (it is most convenient to use a crank) two bolts that attach the electric fan to the casing on the left and four nuts, two of which are located on the top and two below (see photos 2 and 3 below) and then remove the electric fan by pulling it to the top and put it aside.

2) Next, remove the sound signal, because it will not allow you to remove the radiator (For how to do this, read the article: "Replacing the signal on the Lada Priora") and then loosen all the clamps that attach all the supply pipes to the radiator (see. photos 1 and 2, pay your attention to photo 1, one more pipe is indicated on it with an arrow, so do not miss it) and disconnect them, immediately after which unscrew the two nuts that attach the radiator to the body (see photo 3) and then remove the holder that keeps the hose from dangling from the hole in the cross member of the engine compartment (see photo 4), well, that's it, you can safely tilt the radiator to the car engine after that and then pull it out of the engine compartment.

Note!
Look again at photo 1 above, where the arrow indicates the upper hose, unlike the nozzles, it is not fastened with a worm clamp, but with a tape clamp, tape clamps are not convenient and after the first unscrewing, it is already difficult to fix the hose with them, so that it holds just the same rigidly, therefore, replace this clamp (if you have a tape clamp), replace it with a worm, it is much more convenient and you can tighten it with a wrench or screwdriver!

Installation:
Before installing a new radiator or re-installing the old one (if you solder it), check for the presence of two pillows on which the radiator stands (see photo 1), they may still remain in the dowel pins, so look everywhere, torn or lost elasticity pillows, replace with new ones , as well as remove and check the rubber-metal bushings, if necessary, they also change to new ones.

Note!
If you still decided to install the old radiator (Perhaps you just took it off in order to gain access to other parts), then before installing it, rinse it from the outside with a stream of water and dry it thoroughly, and by the way, before connecting the pipes back to the radiator, lubricate them with a sealant, a small layer, otherwise the pipes may begin to leak, which will cause you a lot of inconvenience and problems with the constant purchase of coolant!

Additional video clip:
Study the video that is posted below, using the example of a VAZ 2111 car, it shows how to properly remove the radiator from the car.

Would need: remove the radiator fan, drain the antifreeze and prepare a “8” head, an “8” head with an extension, a “10” head, a screwdriver.Removing the Priora radiator:

Remove the sound signal from the radiator by unscrewing the bolt with the “8” head.

Loosen the clamp of the radiator inlet hose using the "8" head.

Detach radiator inlet hose.

Loosen the clamp of the radiator outlet hose using the “8” socket with an extension.
Detach radiator outlet hose.

Unscrew the two nuts securing the radiator to the upper cross member using the "10" head.
The photo shows the attachment points of the radiator to the upper cross member.

Tilt the radiator towards the engine.
Remove the radiator steam hose by first loosening the clamp with a screwdriver.
Remove the Priora radiator by removing the pins of its lower mounting from the rubber cushions

Installing the engine radiator is carried out in the reverse order. The old radiator cushions should be replaced with new ones, and the strap clamp of the steam hose should be replaced with a worm gear. Pour antifreeze into the cooling system.

For reference:

By the way, in order to extend the life of the radiator, it is recommended to install a protective grill.

If car radiator leakingthen most of us resort to replacing it. However, in most cases it is possible not to change, but repair radiator... Sometimes no skills are required, but sometimes it is impossible to do without knowledge in the field of welding or soldering. We learn to define the state and try restore the radiator with your own hands.

The most common problem when, due to old age, appears radiator leak... Coolant (coolant) runs out of the joints between metal and plastic, which automatically leads to overheating of the engine. It is not always possible to find a replacement radiator, and repairs will cost at least 2 times cheaper than a new one.

Hello everyone! My name is Mikhail, now I'll tell you a story about how I managed to exchange a dvenashka for a 2010 Camry. It all started with the fact that I was wildly annoyed by the breakdowns of the two, like nothing serious broke, but on little things, damn it, so many things that really started to enrage. Here the idea was born that it was time to change the car to a foreign car. The choice fell on the tayet Camry of the tenths.

Further we will talk about car radiators in general and it does not matter if it is a repair of a heater radiator, an air conditioner radiator or a radiator of the engine cooling system.

Chemistry radiator repair... Minor damages can be repaired with special products known on the market as radiator refurbishing fluid, radiator sealant, or powder reductants. The principle of operation is approximately the same: pour the radiator reductant into the engine cooling system (SOD). The resulting mixture will seal cracks when exposed to air.

Video demonstration of the operation of the liquid for the restoration of the radiator:

Chemistry is different from chemistry, therefore, it is impossible to answer for the quality of such a method as a whole. For example, a low-quality reductant may not help, but, on the contrary, harm it by clogging up the entire SOD. For example, the stove will stop heating and it will be necessary to flush the SOD or change the radiator of the stove. Better chemistry is able to eliminate radiator leakage only for a while (from several days to several months). In this way, radiator repair chemistry is only a temporary solution to the problem.

Repair honeycomb radiator can be a mixture of epoxy resin and hardener. Degrease and pour the substance into the damaged honeycomb and level it with a spatula. Now the holes in the radiator are 100% sealed.
In general, the folk method involves the use of many materials for sealing, I just showed the main ones. Whether this approach can be called a high-quality radiator repair, decide for yourself.

The following instruction assumes knowledge of basic welding and soldering skills.
To repair the radiator permanently, it must be removed, but before that, the coolant must be drained from it (described in detail in the article on cleaning the radiator). Now that the radiator is dismantled, we can determine its condition, whether the radiator can be repaired or replaced with a new one.

Repair the radiator by soldering... We clean the place that will be restored well and solder a piece of sheet brass (brass radiators). Here you need to resort to using a gas torch and a soldering iron.

If cracked radiator tubes, then it is better to replace them with new ones. We heat the solder until it becomes soft and take the tube out of the tank. In its place we solder a new one. The disadvantage of this method is the effect of high temperatures on the elements of the radiator, which leads to its internal deformation. Therefore, it is better to use argon arc welding (argon welding).

Radiator repair by argon welding... The filler material here is a special welded aluminum wire. Special equipment is indispensable here. It should be noted that places treated with argon will be protected from oxidation.
Repair of a radiator using gas-dynamic spraying... When a special powder is accelerated along the inside of the radiator at a very high speed, a 1-1.5mm thick coating forms on the damaged surface. It makes no sense to describe these two methods, because they cannot be done at home.

Video showing argon radiator repair:

Repair car radiator can be done in various ways, each of which has its own advantages and disadvantages. In one case, there will be a short-term repair of the radiator, and in the other for a long time. If you doubt your abilities, then it is better to entrust the mission of restoring the radiator to specialists and argon welding. They will not only repair, but immediately clean the radiator and, if desired, install a brass tank.

If the radiator is damaged after a head-on collision of the car, then the repair will cost a pretty penny. It is more correct in this case to buy a new high-quality radiator.

In order to get rid of constant fines from cameras, many of our readers successfully use Special Nano Film for numbers. Legal and 100% reliable way to protect yourself from fines. Having familiarized ourselves and carefully studying this method, we decided to offer it to you as well.

What method of radiator repair do you recommend?

Which is better to use a radiator on the top ten?
In the last week, a puddle has been pouring in my car in the engine compartment near the pipes. There is a persistent smell of antifreeze. Friends advised to check the stove faucet - it is supposedly plastic and often cracks. It turned out that the reason was not in him. I checked the pipes, tightened them - the puddle appears again. Is the radiator really leaking and will you have to change it?

Which radiator is better for the VAZ 2110 - for the engine and for the stove? Manufacturers often offer both types of this product. A smart choice would be to purchase both variants of the same brand. All these elements of the cooling system can be divided into several types:

The model depends on the engine size: as a rule, old-type radiators are installed on a "ten" power unit of 1.5 liters of working volume, and new ones are also suitable for a 1.6-liter engine.
As for the choice of material, copper products are more durable, have high thermal conductivity, which means they better remove heat. But their price is quite high, and in order to save money, it is quite possible to purchase an aluminum radiator, which is cheaper. Its disadvantages include lower thermal conductivity, as well as susceptibility to corrosion.

The key to a long service life of the radiator, and therefore of the entire engine cooling system, is proper care of it. It is necessary to promptly clean this cooling body from debris that has accumulated in the honeycomb: fluff, leaves, dust, etc. This is an external cleaning. It can be carried out both independently (using a regular hose, brush, soap solution), and at a car wash, where the radiator is rinsed with water or compressed air. In order to flush the radiator from the inside, it will have to be removed by draining the liquid from it.

Unfortunately, leaks from the radiator of VAZ cars are not uncommon. However, do not rush to buy a new one. Quite often, you can do it on your own and save a decent amount. It is possible to repair this element of the cooling system or a heating radiator without even having the special skills of a locksmith and a welder.

Most often, antifreeze leakage occurs due to depressurization at the seams, especially where metal meets plastic.The simplest method, which can be called folk without exaggeration, is cold welding. Visible holes are simply sealed with a special compound, which in appearance and texture resembles plasticine, which hardens in air. It is better to close larger holes with a piece of tin. You need to understand that such a repair is a temporary measure and the radiator will still have to be changed.

A more advanced repair method is pouring a special chemical composition into the capacity of this engine cooling unit. Penetrating into all cracks and holes, the sealant hardens under the influence of air. Be careful, a fake or low-quality composition can "tightly" clog the entire cooling system. The holes are also sealed with epoxy, soldering or argon welding. If the radiator, as they say, cannot be repaired, then you will have to buy a new one.

Participate in the discussion can only registered users.

It so happens that radiator vaz 2110 breaks down, car owners have a question, "What to do?" many immediately go and buy a new radiator, but when it is not possible to purchase, you can get out of the situation differently, namely, fix it yourself.

To repair the radiator, you need to remove it. Before removing, the coolant must be drained, the liquid must be drained from the cooled engine, after which the electric fan is disconnected. As soon as the fan has been removed, the clamps are loosened and the supply and steam outlet hoses are disconnected.

In order to remove the radiator from the attachment point, you need to tilt it towards the engine and only then remove it. The bottom of the radiator is installed on rubber cushions (there are two of them); during assembly, they enter the holes.

To repair a radiator with your own hands, you need to have knowledge, as well as experience in the field of welding and soldering.

The VAZ 2110 radiator is made of brass, so soldering is done with low-melting solders.

To solder the cracks, you need to clean the radiator very well, and only then carefully solder them. But this method is not suitable for sealing holes, in order to eliminate the hole, you need to have an old radiator at hand, from which pieces of sheet brass will be cut, such plates are applied to the hole and soldered around the perimeter. The damaged tube can be soldered, but if its damage is not more than 10%, otherwise the tube is changed.

We need a hot rod, we need to put it in a tube and wait, if the temperature of the rod is sufficient, then the solder will become soft. Next, a tube is removed from the tank with a rod, and a new one is put in its place and sealed.

Argon arc welding is carried out using a filler material, most often a specialized welding wire made of aluminum is used. When using welding of this type, you need to know many nuances, for example: a bloom of aluminum oxide prevents good weldability. To avoid this, argon is supplied to the welding site, the task of which is to reliably protect the metal from oxidation, as a result of which the welded seam becomes without pores and cavities. Also, after heating to the desired temperature, all substances from a solid state pass into a liquid. With such welding, the temperature rises above 400 ° C at this temperature, the aluminum becomes weaker and even a weak impact can crumble.

A temporary solution to the problem of the current cooling radiator can be the use of chemicals.

If the heat exchanger is slightly damaged, you can use a remedy (sealant, powder reducing agent or liquid). The use of this method of repair is especially important if you need to drive to the place where the radiator will be manipulated. Chemical restorers are extremely unreliable, and in cases where a fake is used, it can completely harm the entire cooling system.Therefore, the best temporary solution would be the use of "cold welding".

There is a popular method for repairing radiators. It consists in patching holes using cold welding (a material similar to plasticine, which hardens after use). It is better to close up a small hole in the radiator after degreasing the work surface well. If the hole in the radiator is large, then a piece of tin can be used as a patch, which is again glued with cold welding.

We repair the radiator honeycomb with a mixture of epoxy resin and hardener. Degrease and pour the substance into the damaged honeycomb and level it with a spatula. Now the holes in the radiator are 100% sealed.

Hello everyone!
Today the coolant radiator has flowed on my prior. In my opinion, it flows in the place where the aluminum meets the plastic on the sides in the brackets.
How can you glue these places?
Epoxy adhesive, two-component adhesive?
What would your friends advise?

there the rubber gasket is squeezed with a piece of iron, do not glue anything, throw away only, junk
I have a native drip for the third winter, I changed it - it was enough for one winter

There is also glue “It Can't Be Stronger”, it will also help.

Buy a new one. He's not expensive. Clay is so, to get there, if not at home. Or ride until the paycheck)). The fact is that when heated, the radiator material expands, as indicated by the school physics course)). When you glue, the patched place will still flow again after a certain number of expansion-contractions.

Ours is expensive, I have an air conditioner halla

Then the glue is epoxy EPF Soviet. This is the most reliable gluing option. But again, enough for half a year, hardly longer.

I read the comments. It turns out there are so many more ways to fuck yourself and the car and the radiator with disassembly and gluing. Honestly, I would never have thought that someone was doing this. Well, solder the exception. Went bought changed. Yes, it can be expensive, but what is nonsense to do.

Nonsense ahahahaha)
It's probably smarter to buy, but to do it yourself is nonsense, logic ...
Thanks for the positive)))

Doing it yourself is not nonsense. And to repair something that, in principle, is not being repaired, this is what I called nonsense. And I did not build comparisons of what is smarter to do and what is dumber. And I wrote my opinion at which I will stay.

Yes, I do not pretend to be your opinion. You write that the author is engaged in nonsense trying to glue the radiator. Why buy NEW, if the old can still be repaired, such a logic did not occur to you? Is this nonsense?
Then let’s buy a new car after a tire puncture, so that they don’t do nonsense gluing the tires.

You notice the difference. Between doing well with your own hands and doing with your own hands what will break soon. Well, it's like sewing up a virgin to a woman. Seriously. They will pierce it anyway. Not to mention the removal of the radiator from the prior with the Conder. To replace, the floor of the car must be disassembled. I changed it myself. I don’t want to remember this terrible dream. To do this procedure every few months you have to be that perverted one with nerves of steel. I don't mind letting it repair. Well, then, personally, I think it's not worth it.

From where do you know what if you do something breaks? If something breaks down after your repair, this does not mean that someone else has the same thing)
And why buy a car at all, if something breaks there and what kind of crap there will be something to remove, repair or glue, maybe it is better then to walk on foot, although the sole can also wear off on foot on foot)))
In services, they solder radiators, and even glue them, probably they are also doing nonsense, it is easier to buy a radiator, because they do a new shchay too well ...

It does not break after my repair. Since what is repairable is restored, if not, then the unit or unit is replaced. And I know, for example, from the comments in this post. Not one person wrote that the repair will help for a long time. Replacement only.That is, according to you, everyone is wrong here. Well, okay. I will tell the author where to buy cheaper. Maybe the price will suit him. Than to talk here is easier to help than something really sensible.

I agree, help the author, but not with phrases it is better to buy, or to repair nonsense with your own hands.
For your information, there are few parts in the car that cannot be repaired, for example, a broken headlight glass.
And yet, I have been dealing with machines for 20 years, I know what is being repaired and what is not, how to do this or that, and how long it will take, so the opinion of someone here wrote something to me deeply on the drum.
In my life, I altered the sea of radiators, all of them worked for sure not half a year.
The author said he had no money, it also happens, he asked a specific question, he knew to advise “buy” without you)

I will ask this message to be duplicated to all the participants in this topic, otherwise it’s not very much to troll me alone. And so look good advice will be added to the author.

Yes, let's duplicate - the ROAD IS GOOD ON THE ROAD, RIDE EVERYTHING IN THE MEETING AND PUNCH THE TIRES!))

better to replace. I tried to disassemble, clean, assemble. Enough for 4 months. Strangled a toad and put a brazed copper orenburg. I don’t regret it. A small crack appeared once, antifreeze was leaving a drop a day, the radiator just got wet. I took it off, soldered it and ride on 🙂

Only a replacement will help, all sorts of powders will not help you, you will clog an already inoperative system, since you get confused, immediately change the radiator of the stove, and of course a new liquid in the wheelbarrow)

The radiator must be replaced if a coolant leak is detected from it.

In a workshop with special equipment, the VAZ 2170 radiator can be checked and repaired.

You will need: a key "10" (or head), a screwdriver with a cross-shaped blade, pliers with long thin jaws.

1. Drain the coolant (see "Replacing the coolant").
2. Remove the Lada Priora radiator fan (see "Removal and installation of the radiator fan with a casing").
3. Remove the sound signal (see "Removal, installation and adjustment of the sound signal").

4. Loosen the clamp tightening the supply hose to the radiator.

5. . and remove the hose from the radiator pipe of the VAZ 2172.

6. Disconnect the outlet hose from the radiator in the same way.

7. Unscrew the two nuts securing the radiator to the body of the VAZ 2171.

8. Remove the steam hose holder from the hole in the upper cross member of the engine compartment.

9. Tilt the radiator towards the engine. Loosen the band clamp on the steam hose ...

10. . and remove the hose from the VAZ 2170 radiator fitting.

Hose band clamps are inconvenient to use and difficult to re-seal the connection. We recommend replacing the band clamps with commercially available worm gear when first disconnecting the hoses.

11. Lift the radiator up.

12. Remove the two bottom mount pillows from the radiator if they remain on the radiator locating pins, or remove them from the holes in the cross member if they remain on the body of the VAZ 2171. Replace the torn or lost elasticity pillows.

13. Remove the rubber-metal bushings from the radiator brackets. Replace torn or loose rubber grommets.
14. Rinse the outside of the radiator with a jet of water and dry. If the plastic tanks of the radiator are cracked, replace the radiator
15. Check the tightness of the Lada Priora radiator by plugging its pipes and lowering it into a container with water, supplying air to it under a pressure of 0.1 MPa (1 kgf / cm2). Air bubbles should not appear from the radiator for at least 30 seconds. If the radiator does not fit completely into the container, check it sequentially from all sides.
16. Establish the priora radiator in the reverse order of removal, first putting on the pins of the radiator cushions of the lower mount and inserting the bushings of the upper mount into the brackets.
To further exclude the possibility of coolant leakage, before connecting the hoses to the VAZ 2172 radiator, lubricate the radiator pipes with a thin layer of sealant.
17. Install the electric fan and all removed parts in the reverse order of removal.
18. Fill with coolant (see "Replacement of the prior's coolant").
