DIY repair nissan murano z51

Details: DIY repair Nissan Murano z51 from a real master for the site my.housecope.com.

Today's report will be the overhaul of the JF010E CVT on the Nissan Murano Z51.

Mileage at the time of repair is 190,000 km, the age of the car is 7 years old, Murano is still of Japanese assembly.

Recently, during heating, the pressure decreased and error P0868 appeared, small dips in the dynamics were felt.

We suspend the engine, remove the front subframe with levers and stabilizer, then remove the variator.

We disassemble and inspect the details.

The cone is in perfect condition, there are no traces of the belt axle box, there are no workings in the grooves - we leave them.

The belt is in perfect condition, the degree of stretching is minimal, the factory notches on the links are not erased - we leave it.

The pump gears and the back cover have no traces of wear, the pressure reducing valve has wear, but this has not affected the pressure in any way - we bore the pump hub and install a valve with an increased diameter.

The valve body has wear, when heated, the thermal gaps increase, some valves wedge due to depletion, so the pressure drops - we change the valve body to a new one.

The seat of the differential bearing cage is squashed in the bell - we change the bell for a new one.

In the back cover, the bearing seat of the driven shaft has been worked out - we restore the seat with a sleeve.

Friction discs burned a little - we are changing to new ones.

We send the torque converter for repair.

We exclude the standard radiator and put Hayden radiators in front of the main one.

Timely intervention in the variator helped to avoid damage to the surfaces of the pulleys and belt segments.

We wish everyone a long and trouble-free operation of your vehicles!

In order for your Nissan Murano to serve faithfully to its owner, you need to constantly monitor its technical condition. Regular diagnostics and repairs of the Nissan Murano are the key to trouble-free operation.

To repair the Nissan Murano less often, you need to first of all monitor consumables that change either after a specified period, or depending on the mileage. Checking and replacing consumables on the Nissan Murano is done according to the routine maintenance table, which indicates the intervals with the mileage and the type of work.

Nissan Murano repair and replacement of consumables includes:

Change the oil in the Nissan Murano engine
Change the Nissan Murano oil filter
Change cabin filter for Nissan Murano
Change the oil in the automatic transmission Nissan Murano
Change power steering fluid Nissan Murano
Replace antifreeze with Nissan Murano

Timely replacement of oil and filters for Nissan Murano will significantly reduce the cost of repairs in the future. A clogged air filter will prevent the engine from passing the required amount of air, causing it to choke and consume more fuel.

If you do not change the oil for Nissan Murano, then it will lose its properties, become very cloudy and thicken, simply turning into a thick substance, that is, fuel oil. This oil does not lubricate the moving parts, but only hinders their operation.

The price for repairing a Nissan Murano consists of the following components:

Prices for Nissan Murano parts for repair;
Price for the work of an auto repairman / specialist;

The most expensive are original spare parts for Nissan Murano from the manufacturer. Each such spare part has its own part-number, by which you can find analogues from other manufacturers.The prices for non-original spare parts for Nissan Murano 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 Nissan are faked most often, since there is always a demand for them.

Types of payment for the repair of Nissan Murano:

official, with documents and a guarantee;
unofficial, without documents, by personal agreement.

First of all, it is necessary to clearly set the tasks for the repair of Nissan Murano, and if the problems are not obvious, then diagnose the Nissan. 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 Nissan Murano 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 Nissan Murano 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 Nissan Murano 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 volume of work you have chosen for the repair of the Nissan Murano, 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 Nissan Murano, being in the working area with a car repair shop 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 the repair of Nissan Murano, according to the rules of the car service, you need to hand over the car, then be sure to draw up an act of acceptance of the 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.

The Nissan Murano acceptance certificate for repair or diagnostics includes:

List of works and faults required to repair the car;
List of spare parts for replacement;
Diagram and description of the presence / absence of defects on the car that do not require elimination during the repair process;
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 the car, the second to repair the Nissan Murano, and the third to hand over the work. If any inconsistencies are found later, it will be more difficult to prove it.

The first Nissan Murano entered the market in 2002. Subsequently, the Japanese automaker released 2 more generations of the model: Z51 and Z52. Thanks to the fact that Murano has been produced for 15 years now, we have been able to collect statistics on typical malfunctions and repairs. The conclusion that can be made: breakdowns are not always associated with design flaws, because the owners often violate the maintenance regulations and operational standards. But first things first. Let's start with the technical stuffing, and after that we will consider the features of the Nissan Murano repair.

1st generation

From 2002 to 2008, a model with the Z50 index was produced. Under the hood was a 3.5 liter gasoline engine with 245 horsepower. Versions with front-wheel drive or all-wheel drive are available to the buyer. A V-belt variator works in tandem with the motor. The car accelerates to a hundred in 8 seconds.

II generation

Murano Z51 is built on the same platform as Nissan Teana. The crossover has changed externally, but from a technical point of view it remains similar to its predecessor. Under the hood is the same 3.5-liter unit with a solid 336 Newton meters of torque. The internal combustion engine is combined with an updated continuously variable variator - Xtronic. Murano is also found with a 2.5-liter gasoline engine with 170 horsepower. Even rarer for Russia is the 2.5 dCi version with 190 horsepower.

III generation

In 2014, a new generation of sports crossover was presented. A version adapted to domestic roads is supplied to Russia, with special shock absorber settings and modernized springs. The engine and gearbox remained the same. But in 2015, the debut of a hybrid version with a turbocharged 2.5-liter engine and a robotic transmission took place. An extensive set of security systems has also appeared.

According to the automaker, the consumption in the city of the all-wheel drive version of the Z50 is 11.8 liters per 100 km, and on the highway - 9.4 liters per hundred. The owners call completely different figures - from 14 to 19 liters per 100 km in city mode. The consumption of gasoline in the city is highly dependent on driving style. The new generation Murano Z51 and Z52 have 1-2 liters less fuel consumption, although in general everything remains the same. And this is quite normal for a V-shaped "six".

If you want to reduce fuel consumption, extend the life of the oil and the engine itself, and normalize dynamics and power, use the FueleXx fuel additive. It is a well-proven combustion catalyst that can reduce Murano's fuel consumption by 10%.

FueleXx promotes de-carbonization of piston rings. But its main advantage is the extension of the catalyst life. In Russian realities, they tend to melt and crumble: particles through EGR enter the engine cylinders, thereby provoking serious damage. FueleXx protects Nissan Murano catalysts from premature wear, which is especially important for American versions with small and fragile catalysts.

The engine is equipped with forged connecting rods and a crankshaft, the pistons are coated with a layer of molybdenum. A system has been introduced into the design that changes the valve timing. For the timing belt, a reliable, durable chain was used, capable of walking up to 300 thousand km. The power unit is not particularly whimsical. For stable operation, you need to change the oil in a timely manner (preferably every 8-10 thousand km), flush the throttle valve, and clean the radiator. Cleaning the radiator is necessary in order to avoid overheating. Although it is possible when the valve cover is warped, the cylinder head is bent.

A problem that almost every Murano owner faces is high oil consumption. This is due to catalysts that are sensitive to low-grade fuels and quickly deteriorate. Ceramic dust enters the lower catalysts, and then wear products grind off the walls of the engine cylinders. This leads to a drop in compression, increased fuel and oil consumption (up to 0.5 liters per 1000 km). To solve the problem, they make a full overhaul of the engine and install new catalysts. Sometimes, instead of overhead catalysts, flame arresters are installed, which affects the environmental characteristics of the internal combustion engine.

You can extend the life of the VQ35DE motor with proper maintenance, preventive flushing with MF5. This is the development of RVS-Master, which is designed to clean the engine oil system. MF5 removes wear debris from working surfaces and normalizes pressure in the oil system. Flushing is used during routine maintenance to change the oil, not only to clean the cylinder walls from carbon deposits, but also to de-carbonize the rings.The composition is thought out in such a way that the rubber seals do not lose their elasticity as a result of contact with liquid. The product is based on magnesium silicates.

Note: with proper maintenance of Murano, the VQ35DE engine runs up to 500 thousand km.

Initially, Murano was equipped with a Jatco CVT of the JF010E series. The designers tried to design the transmission in such a way that the consumption was minimal, and the acceleration was as fast as possible. But this entailed an increase in the load on the cones and the belt. To strengthen the cones, a hard alloy material was sprayed onto their surface. By the way, on the Murano version with a 2.5-liter gasoline unit, a more successful JF011 variator was mounted.

Most JF010E breakdowns are due to overheating and contamination of the lubricant. This leads to jamming of the valve, which starts to turn on not smoothly, but with a jerk. Because of this, the dynamic loads on the iron itself increase, the cones and the belt quickly wear out. To eliminate the malfunction, change the valve or pump assembly. If the oil in the Murano variator is untimely changed, the valve body plungers and valves may wear out.

There are several secrets that can significantly extend the resource of the JF010E variator:

Warm up the transmission before driving in cold weather. This will protect the belt from abrasion and tearing, and also protect the cone. But, in general, the durability of this variator depends on the condition of the driving and driven shafts.
Change the oil in accordance with the manufacturer's regulations, or more often depending on the operating conditions. The developers recommend doing this at least every 40-50 thousand km.
Use the composition RVS-Master Transmission Atr7, which compensates for wear, extends the service life of parts, forming a protective cermet layer on the surfaces.

Without any preconceived opinions, the Nissan Murano (Z51) has both positive reviews from the owners and, unfortunately, negative ones. This car certainly attracts with its appearance, and can also surprise with its internal comfort. But, as you know, the car is judged from the experience of the owners, not by the leather seats, but by the price-quality ratio. Therefore, the following are the main problems and weaknesses of the second generation Nissan Murano after the description, which it will be possible to conclude about the worthiness of Murano among its competitors of other brands and models.

If nothing bad can be said about the engine, then, unfortunately, there is something to talk about about the second most important unit. Variators in general can be said to be reliable have not yet been invented, therefore it is not known to the ordinary driver who operates the Nissan Murano why it was installed on this particular model of Nissan. In a word, the variator on Murano is problematic. The first signs of a "dying" variator are the lack of acceleration when increasing the rev. It is important to note its fragility and high cost of repair. Therefore, when buying, it is important to check the condition of the variator.

An equally important unit and at the same time problematic is the transfer case. It can be noted right away that there were not a significant number of serious problems with the "razdatka", unless, of course, the lubricant was available, but the main problem in this unit is the ever-flowing oil seals. Therefore, when buying, at least what needs to be done is to make sure in the pit that there is no oil on the transfer case.

Of course, we can say that due to various reasons ranging from natural operating conditions to artificial reasons, chrome on many cars is a headache. On some, it lasts a little longer, and on some it is not much smaller, but on Nissan Murano, problems with chrome begin after the first years of operation. Therefore, when buying, it is important to pay attention to the condition of the chrome coatings.

Front anti-roll bar bushings.

Most Murano owners often encounter such a problem as knocking of the front stabilizer bushings. It is important to note that this is not even a weak point, but design mistakes. Therefore, when buying, it is important to ask the owner whether these elements have changed or not. The bottom line is that this problem manifests itself precisely with factory bushings. Although this is not critical, it is necessary to know about it before buying.

We have a Nissan Murano Z51 (Nissan Murano), produced in 2010, for repair, on which it is necessary to replace the rear brake pads. We will show you how to do it correctly and quickly with your own hands.

We lift the car and remove both rear wheels. We unscrew the lower and upper guide bolts:

We immediately check their operation, condition, availability of lubrication. In our case, the lower guide does not come out, you will have to remove it together with the bracket in order to clean the thread and lubricate it fully.

We take out the old brake pads, the inner one is very tight, this suggests that a lot of dirt has accumulated under the plates. We take it out with a screwdriver:

The block shouldn't come out so tight! We unscrew and unscrew the bolts that hold the caliper bracket:

Since we have climbed this far, we will also remove the brake disc to assess the condition of the parking brake pads. We pry the piston boot with a screwdriver and squeeze out a small amount of grease for the calipers from the syringe.

Using a clamp, we sink the piston into the caliper:

When we install the cylinder on the caliper bracket, on the new pads, if the boot protrudes beyond the piston, there is a possibility of "cutting" it, be careful. We remove the springs from the bracket, carefully clean the seats with a brush with metal bristles. We remove both anthers and clean out the old grease from the inside, then grease it again.

We put the bottom guide and twist the bracket:

We put back the cleaned "springs" (heat shields), put new pads, we have them from NISSHINBO, catalog number PF-2466. Internal pads with squeak, external without. Putting it up in the reverse order. Before starting the movement, we press the brake pedal several times until it stops.

The second generation Nissan Murano (factory index Z51) has been produced since 2008. The mid-size crossover is built on the Nissan D platform, which is at the heart of the Teana II. In 2011, the Nissan Murano received minor changes in appearance. In the same year, commercial production of the Murano was launched at the Nissan plant in St. Petersburg.

Engine and transmission

There is only one power unit installed on the crossover - the time-tested V6 with a working volume of 3.5 liters and 249 hp. (VQ35DE). This engine is recognized as one of the best among gasoline analogues. The motor does not cause problems.

With the transmission, things are a little different. Some owners have to deal with a malfunction of the transfer case or variator (CVT), since there are few such cases. So some "lucky ones" were replaced by a faulty CVT with a mileage of 30-60 thousand km. Reasons for contacting the service: jerky work of the variator, "dullness" of the box and the lack of acceleration when increasing the speed. For the repair of this type of boxes in ordinary car services, they ask about 60-80 thousand rubles. But don't be too scared. Many auto mechanics of unofficial services claim that under normal operating conditions the variator easily overcomes the mark of 150-200 thousand km, and in sparing ones - and 250 thousand km.

There are cases of replacing the transfer case with a mileage of 60-80 thousand km. By the way, the cost of handouts in the online store of spare parts is about 180-200 thousand rubles, while the officials have more. A real epidemic of the current transfer case oil seals broke out on cars manufactured in 2009-2011 with a mileage of more than 15,000 km.The reason is a defect in the casting of the variator case. Nissan sent out a technical bulletin to service centers explaining how to fix the problem. The bottom line: due to the overflow on the variator case, which was not provided for by the design, the complete shrinkage of the bevel gear at the junction of the box with the distributor was not ensured - the units were installed with a bias. During operation, oil seals broke, and a leak appeared. Ignoring the problem can lead in the future to a complete loss of working fluid and failure of the transfer case. Authorized services, according to the prescription, grinded down the problem protrusion on the variator housing and changed the oil seals. On 2012 models, the casting problem has been resolved. But according to some auto mechanics, on Murano 2012, there are still cases of fogging of the transfer case oil seals. In the meantime, the runs of 2012 crossovers are small and there are no reliable statistics on the problem.

Many Nissan Murano owners noted the appearance of dull knocks in the front suspension with a mileage of 10-20 thousand km. The reason is the front anti-roll bar bushings. When a problem was detected, authorized Nissan services changed the bushings, but after 10-20 thousand km, knocks appeared again. Nissan later reworked the crimp plates to provide tighter shrinkage for the bushings. After replacing ferrule bushings, the problem does not recur.

The howling of the power steering pump in the cold after starting is another common phenomenon on the Nissan Murano. The probable reason is the power steering fluid, which is strongly thickened in the frost. It is noticed that after changing the fluid at the dealers, no changes occur, i.e. the howl remains. And if the "original" liquid is replaced with a high-quality analogue, the howl often goes away. An indirect confirmation of the presence of problems with the fluid is the "winter death" of power steering pumps on warranty vehicles. The cost of a new pump is about 20-25 thousand rubles.

Body and interior

After 2-3 years of operation, many owners note problems with the chrome coating of decorative body elements: chrome becomes stained, swells or peels off the varnish. Headlights often fog up, and frost appears on the inner surface in cold weather. The cost of a new block headlight from dealers is about 42 thousand rubles. Some owners on Murano older than 2-3 years notice a slight sagging of the front bumper.

Sometimes there are cases of water getting into the car interior due to insufficient amount of sealant on the welded seams of the front fenders or the absence of the bonnet cable plug behind the left fender.

In winter, some Murano owners note the appearance of squeaks in the interior plastic before the interior warms up. The cause of the annoying squeak at the bottom of the windshield is sometimes the outer plastic lining. Some owners have had to deal with the grinding and play of the driver's seat due to the wear of the sled. Many people note the insufficient quality of the leather upholstery of the seats: creases and folds appear on the surface relatively quickly.

There are frequent complaints from the owners of Murano about the slow warming up of the cabin in winter: the warm air does not start blowing immediately. The reason is similar in essence to the problem of power steering pumps: the concentration of antifreeze does not correspond to the temperature conditions of vehicle operation. Antifreeze freezes and forms plugs. In addition, some notice an increase in the temperature of the "engine" on the index to critical values, and the air from the deflectors still remains cold. In Nissan services, they are aware of the problem and, when contacting, replace the coolant.

There were no systemic problems with the electrics.

In general, the Nissan Murano performs well. There are not so many problems. There are certain risks of failure of the variator or transfer case, but they are not high. The main thing is correct operation and timely maintenance.

Nissan Murano CVT is a kind of replacement for the traditional standard gearbox, but has a simpler and more intuitive design.Nissan Murano is a rather powerful and massive car, and this fact has some adverse effect on the serviceability of this equipment.

Usually, all cars of this model are characterized by similar malfunctions that will require further CVT repair Nissan Murano... These include the following factors:

malfunction or wear of the drive or driven shaft;
wear on the drive chain or belt;
extraneous noise directly in the equipment itself.

Most often, such problems appear when the mileage indicators reach 120 thousand kilometers. They can be caused not only by the aggressive nature of the ride, but also by the malfunctioning of the electronic control unit.

A frequent factor causing breakdowns is untimely replacement of the oil or filter in the gearbox... May obstruct the operation of the variator valves ingress of unfiltered shavings and powder into them, which is formed during the operation of disks.

Excellent prevention of various equipment breakdowns, there will be several actions that every driver should remember:

With each achievement of a mileage of 30 thousand kilometers, it is necessary to change the oil, as well as the filter in the device.
Every 70 thousand kilometers of a car's run, it is necessary to replace the step-by-step electric motor and sensors that determine the speed of rotation of the shafts.
Follow all the recommendations of specialists and manufacturers for the maintenance of the variator.

How to repair a variator One of the most common problems that need to be carried out CVT repair on a Nissan Murano caris the emergence of various extraneous noise in the equipment itself... Carrying out repair work with your own hands in this case is quite possible, you only need a certain literacy of the motorist and a set of tools.

You may need such improvised means: wrenches, screwdriver, hammer, clamps, work table with good space.

It is necessary to store all the extracted parts in special bowls and place them in the sequence of disassembly, as well as photograph the most difficult moments in order to quickly and correctly carry out the assembly. It is also better to inscribe every detail with a marker, which will also help to avoid confusion during installation work.
