DIY highlander repair

Toyota Highlander engine repair. Initially, the car came with the problem of antifreeze leakage from the rear of the cylinder head in the area of ​​the intake manifold. The owner had a preliminary suspicion of what the malfunction was. After the diagnosis, the diagnosis was confirmed.

The problem was obvious due to its systematic nature in 2AZ-FE engines of a certain year of manufacture. I talked about this problem in detail in the next article. After consulting with the owner, it was decided to overhaul the engine, along the way, radically eliminating the problem with the thread of the cylinder head bolts, so as not to return to it.

Before the overhaul, an approximate cost forecast was drawn up and agreed with the owner of the car.

The engine on this car is removed assembled with an automatic transmission. Before removal, all service fluids were drained, except for the oil in the automatic transmission. The braid, all the pipes, etc. were dismantled from the passenger compartment, after which the subframe with the engine and automatic transmission is lowered down.

We dismantle the wiring braid from the engine and all attachments.

So, after dismantling all attachments, we got to the place of direct leakage of antifreeze from the engine. Antifreeze flows from under the junction of the cylinder head and the cylinder block itself, since the thread of the cylinder head bolts in this part is pulled out. This happened due to a technical flaw in this engine, namely the long thread of the cylinder head bolts.

The photo clearly shows how the thread from the block remained on the cylinder head bolt... In the photo on the right, the attachment points of three bolts are highlighted, in which, first of all, the thread pulls out. This is due to the high thermal load, since these bolts do not have one of the sides touching the outer wall of the block, which cools the block in contact with the environment. The second factor that aggravates the thermal stress on the threads is vibration isolation, which tightly closes this area between the block and the intake manifold, which weakens the cooling of the block wall.

We disconnect the engine from the automatic transmission and install it on the stand. Next, we dismantle the cylinder head. Three central bolts on the back side were unscrewed by hand, hThis indicates damage to the threads of the bolts.

We dismantle the small and large engine sump and reach the piston group. As you can see in the photo, the engine is quite clean, which indicates a timely oil change. No carbon deposits were found. We take out the piston group and the crankshaft from the block bed.

After disassembling the engine, we proceed to the bulkhead of the cylinder head. First of all, the cylinder head is checked for deformations. If the cylinder head has led, then it is mandatory sent to the grinding of the plane. We grind the outlet and inlet valves. If there are sinks on the valves, they are replaced. After lapping the valves, the cylinder head is washed from the remains of abrasive and the valve stem seals (oil seals) are changed, after which the valves are assembled. After assembling the valves, the thermal clearances of the valves are adjusted. If necessary, change the adjusting glasses.

Now we turn to the restoration of the thread of the bolts, fastening the cylinder head. First of all, we cut the M14x1.5 thread for our screwdrivers. We install the screwdrivers, having previously treated them with an anaerobic thread sealant. We set the screwdrivers to a certain depth from the upper edge of the block.

In our case, we used different cylinder head bolts. Their fundamental difference from the standard ones in the barrel diameter is that it is thinner, due to which the bolts have more progressive tensile characteristics than the standard ones. This allowed us to set the screwdriver to a shallower depth.

After installing the screwdrivers, we turn to the piston group.Before installing the pistons, they are washed and cleaned of carbon deposits. We install a new set of piston rings on the piston and assemble the piston group and KShM.

We assemble the pallet and install the balancing shafts. Now let's move on to the top. Install the cylinder head gasket.

We install the cylinder head on the block and proceed to broaching the cylinder head bolts.

We install the camshafts and assemble the gas distribution mechanism (timing).

Install the front timing cover, then the pan cover and valve cover. We install part of the attachments and the motor is ready for installation on the car's subframe.

We install the engine on a subframe and assemble the remaining attachments. After a second, thorough check for defects. The subframe with the engine is installed in the car, after which all communication systems of the engine are installed. Service fluids are filled in and the engine is started. After the test check, a second check is carried out for leaks and extraneous noise. Then the car is ready for use. This is the work on repair of the Toyota Highlander engine finished.

All work was carried out in our car service - Toyota Lublino.

1. Prices for Toyota Highlander parts for repair;
2. Price for the work of an auto repairman / specialist;

The most expensive are original spare parts for Toyota Highlander from the manufacturer. Each such part has its own part-number, by which you can find analogues from other manufacturers. The prices for non-original spare parts for Toyota Highlander are lower than the factory ones, but there is a possibility of getting a low-quality fake, which has a short service life, or will not work at all. Filters, oils, candles, belts, brake discs for Toyota are faked most often, since there is always a demand for them.

First of all, it is necessary to clearly set the tasks for repairing Toyota Highlander, and if the problems are not obvious, then diagnose Toyota.Teapot car enthusiasts are always welcome to service, because they can be imposed a number of works and replacement of spare parts that are not necessary.

In a car service, prices for Toyota Highlander repair can be fixed for each type of service and be the same for all car brands: suspension diagnostics, oil change, replacement of pads, replacement of air filters. An alternative price option, when payment is made for "1 standard hour", has its own for each car model.

In this case, each Toyota Highlander repair operation is determined by timing, that is, the time it takes. This is called "Rate of Labor". Each car manufacturer indicates these numbers in the tables of reference books for each car model separately.

It often happens that the repair of a Toyota Highlander from a mechanic takes longer than the standardspecified in the work reference. In this case, you have the right to pay only for the fixed standard hours allotted for this operation. Whether the auto repairman will do it more slowly, or faster, depends on his qualifications.

It is very important to require the issuance of a work order for the amount of work you have chosen for the repair of a Toyota Highlander, as this will avoid disagreements, show your awareness and will be a significant argument if something goes wrong. Indicate what to do with old parts after replacement: return to the client (that is, you), or the car service will dispose of them on their own.

The ideal option is not to give the car keys to anyone, under any circumstances., and only get behind the wheel yourself. Completely supervise the repair of Toyota Highlander, being in the working area with a car repairman all the time. Such conditions often contradict the safety precautions of a car service, but this will save you from most of the problems, and the repair service will be as transparent as possible.

If for repairing a Toyota Highlander, according to the rules of a car service, it is required to return a car, then be sure to draw up an acceptance certificate for a car for repair. This procedure involves the transfer of the car key, and often the registration certificate. An employee of a car service independently drives the car into a box, or onto a lift.

Toyota Highlander acceptance certificate for repair or diagnostics includes:

1. List of works and faults required to repair the car;
2. List of spare parts for replacement;
3. Diagram and description of the presence / absence of defects on the car that do not require elimination during the repair process;
4. Completeness of the car: things, tools, accessories not related to repair.

Upon completion of the work, it is necessary to verify all the points for the documented repair and the actually performed. One employee can take a car, a second to repair a Toyota Highlander, and a third to hand over a job. If any inconsistencies are found later, it will be more difficult to prove it.
