Renault Scenic 2 with an engine capacity of 1.6 liters is a fairly popular car brand among lovers of family compact vans. This car largely repeated the main design and technical features of the previous generation. The chassis was completely borrowed from the 1998 Scenic. Designers and engineers have eliminated those shortcomings and miscalculations that took place in the first generation of this model. The frequency and nature of the breakdowns that occur are not fundamentally different from other similar cars of the same brand. According to the statistics of the Scenic, Megan and Clio models, they are among the most reliable vehicles of this brand, serious repairs of which are required in exceptional cases.

Renault Scenic engines of the second generation are traditionally reliable, however, when servicing and repairing power units, it is recommended to contact specialized specialists or service stations. For example, carrying out work to replace the timing belt with a run of 50-60 thousand km with your own hands can lead to the fact that the position of the gear of the working shafts will be violated. Tightening the mounting bolts to fix it after an approximate “by eye” adjustment is inappropriate, since the quality of such work will be at a low level. In parallel with replacing the timing belt, experts recommend replacing the water pump. To ensure the high quality of this type of repair and replacement of spare parts and consumables, special equipment, tools and appropriate conditions are required.

It should be noted that the Renault Scenic II 1.6 model, like other cars of this French brand, such as the Megan model, is very demanding on original consumables.

The use of products from other manufacturers significantly affects the operation of many components and mechanisms of these vehicles. Overhaul of the suspension of this Renault model may be required after 100,000 km of run.

Renault Scenic I with an engine capacity of 1.6 liters is also reliable, but some components have certain drawbacks, which were eliminated in the second generation of this model. Based on the experience of operating this car, we can conclude that an overhaul of the engine will be required with a run of about 500,000 km. Replacing the timing belt should also be carried out under special conditions by the hands of specialists.

Special attention should be paid to the preventive maintenance of all units of the model of the first sample. Factory sealing defects appear quite quickly, and their elimination can be done with your own hands, having the skills to repair a car.

Also, often repair work requires stabilizer bushings. When replacing them, the help of a specialist will be required, and it will be difficult even for a motorist with a certain experience to do this work with their own hands. The design of the rear suspension of the car has a torsion bar design, and only a specialized specialist can figure it out. Another common drawback is the rapid wear and failure of the front wheel bearings. The nature of such malfunctions can be explained by the peculiarity of the front suspension, and the replacement of these parts can be done with your own hands in garage conditions.

If we compare the described Renault cars, we can make a reasoned conclusion that the design of the second generation model takes into account most of the flaws on the part of engineers and designers. Disadvantages such as a low level of sealing, the quality of electrical wiring is an order of magnitude higher in contrast to the previous model.The list of those works that can be performed by motorists on their own has been reduced.

For example, such an operation as flushing nozzles, the second generation model is needed much more often, unlike the 1998 model. This is due to the more demanding fuel system of the updated car. Whereas engine oil change jobs are easier on the newer model due to the convenient location of the drain port and many other factors.

According to the reviews of the masters at branded service stations, the most problems occur in cars manufactured in 1998. This is due not only to their age and high average total mileage, but also to design features. The car of the second generation is assembled more efficiently and unforeseen breakdowns or premature failure of one or another unit, assembly or part are much less common. As an additional example, experts give an analogy to the evolution of Megan cars. The first models had a lot of shortcomings, but in the designs of subsequent ones they were eliminated.

Renault Scenic 1 gearbox repair (gearbox) can be capital or partial. Repair of the box (manual transmission) Renault Scenic 1 must be done only after the initial diagnosis in a car service. Very often, a third-party opinion that the box needs to be repaired turns out to be erroneous. Causes can also be in the clutch, flywheel and gear selection mechanism.

We offer two options for repairing the gearbox (manual transmission):

Partial (local) repair of checkpoint Renault Scenic 1 - we remove the box, disassemble it, wash it and make defects. Troubleshooting a box is the determination of the cause of its failure, indicating a specific malfunction. A list of spare parts for this malfunction is also provided. After agreement, we carry out repairs to eliminate the specific malfunction that the client applied for. We do not touch the rest of the components and spare parts in the gearbox.

Overhaul of checkpoint Renault Scenic 1 - as well as with a partial repair, the box is removed and completely disassembled, washed and defective. In this case, we are not looking for a specific cause of the breakdown, but do a complete troubleshooting. All components and spare parts with increased wear, all bearings, seals and gaskets are determined and changed.

My gearbox was making a terrible grinding noise in 1st and 2nd speeds. After consulting with knowledgeable people, I came to the conclusion that I, at the very least, need to replace the shaft support in the gearbox.

The box must be completely removed. The work is not the easiest, but you can not do without it. At best, it will take four hours.

The troublesome process of removing the box has been successfully completed. Upon opening it, I was surprised to find that the box was not hermetically sealed with anything special. I only unscrewed a few bolts and the box opened fairly easily.

The red square is an indicator that my bearing has broken.

main shaft. Two parallel bearings are visible, which we replaced.

While my old bearing was being repaired, I cleaned the magnet, which was covered in metal shavings from the broken bearing, as well as a few teeth that had broken off the outer edge.

Install bearings and gearbox back. This took about four more hours.

This article will focus on another chronic sore of many Renault models: Scenic, Megane, Clio, etc. with manual transmission. Namely, gear shifting problems. This material will help fairly advanced owners who have experience in self-repairing their Renault.

Necessary spare parts for replacement using the first generation Renault Scenic as an example:

2. Plastic fixing cuffs (sleeves) - 7700695569

3. Rubber clip (damper)

4. Reverse cable lock (located inside the sphere) 7711129445

5. Anther outer 7700863684

Typical symptoms:

Difficult gear shifting, additional load to make a shift. The most common problems include first and second gear. Over time, the complications increase.

The symptoms are affected by time, mileage, the presence of lubrication, as well as by itself the unsuccessful execution of the mechanism by Renault engineers.

The design developed by Renault engineers is, to put it mildly, unreliable. For the precise operation of the gearshift in the gearbox, the engineers built a complex mechanism that requires complex precision in operation.

The following nodes are responsible for the precise operation in the switching mechanism:

1. Rubber clip - damper

3. Fixing plastic cuffs (sleeves)

Due to the reasons described above (time, mileage, etc.), these mechanisms wear out quite quickly, which leads to problems with shifting the gearshift lever on Megans, Scenics and other Renault models from the Megane line.

The main problem is plastic cuffs, which wear out first and provide vertical play.

In second place is a sphere, in third place is a damper.

The backstage of the Renault manual transmission has other problems - an external boot, the upper clip of the reverse gear cable, more on that later.

Diagnosing a backstage problem

If your car has the symptoms described above, then first of all you need to check for vertical play on the gear knob. We also pay attention to the switching mechanism and the condition of the pressure spring.

The Renault manufacturer and representatives of official Renault dealerships believe that in “our” case it is necessary to replace the ENTIRE mechanism, from the gear knob to the backstage linkage.

If there is a desire to save money, as well as a hand from the right place, we read the description of the repair procedure:

We disassemble the backstage mechanism. Depending on the model and modification of your Renault, the algorithm and procedures may differ, but the principle is the same throughout the entire line.

1. We throw off the gearshift rod from the wings - 1 nut

2. Unscrew the fixing bolts of the gear selector housing - 4 nuts

*For some models, to perform steps 1 and 2, it is necessary to remove the exhaust line, cardan, disassemble the inner panel of the gearshift lever.

3. We remove the entire mechanism of the gearshift handle

4. One of the interesting moments is the removal of the handle! Stock up on patience and vocabulary from the obscene vocabulary.

*I advise you to find holes on the inner sleeve of the handle and expand them first with any suitable metal rod. Next, we stupidly knock down the handle, but I repeat, we do everything through the inner sleeve.

5. Next, remove the retaining ring. We throw off the reverse gear cable and remove the fixing stopper.

6. We take out the entire mechanism. It is important to remember the sequence.

7. We get to the rubber damper we need, in which “the root of evil lurks”. Namely, it contains a sphere and two cuffs, inside the sphere there is another bushing, they are different depending on the car model.

8. We take out the upper cuff from the rubber frame - the damper, then the sphere (it can be disassembled into two hemispheres), the lower cuff

. Important. Mark the top and bottom cuffs.

9. Remove the remnants of the old grease

10. We disassemble the sphere and put one of the halves upside down, you can do it all, or you can not change it, the point is to find the option with the smallest vertical play.

11. Most importantly, we swap the upper and lower plastic cuffs, because. the main wear is on the lower cuff.

*More details: We pick up a sphere clamped by inverted cuffs, if there is a backlash, we try to turn the sphere or its halves over, looking for the optimal position.

12. We collect everything in the reverse order, flavoring everything as much as possible. grease. If you often repair a car, 7711126145 is suitable, or any thick consistency for plastic. You can polyflones, silicones, teflons, etc.

13. We collect everything and put it back

There is another weak point in this mechanism - the outer anther, a thing not fatal, but still.So if you are doing repairs, get ready to replace the boot at the same time.

Description of the process of replacing and bleeding the clutch on a Renault car Scenic 1 and 2. Proper dismantling and installation of the clutch on Renault Scenic models.

It is best to replace the clutch mechanism on a Renault Scenic 2 car on a lift. The replacement process itself is not overly complicated, however, it requires strict adherence to the sequence of work. At a certain stage, the participation of a second person will be required, so it is necessary to agree on assistance in advance.

[del] First you need to fix the cooling radiator with improvised means or disposable clamps. Fixation must be secure to avoid damage to the radiator. Then it is necessary to dismantle the front wheels, having previously turned them in any direction. At the next stage of the replacement work, the engine should be securely fixed. Removing the gearbox and replacing the clutch on the Peugeot Expert. To do this, you can use hydraulic jacks or tables, various improvised means or special devices. Fixing the engine is necessary to avoid possible excessive loads after removal boxes gear shifting.

It is necessary to prepare a clean container of the appropriate volume in advance to drain the gear oil from the shift box gear. In this case, it is better to choose a wide container with low sides.

The preparatory work is over and you can proceed to the main and most important stage of replacing the clutch.

To ensure comfortable work on replacing the assembly, the starter should be removed, having previously disconnected all sensors and wire connections. After removing the battery and the platform on which it is installed, direct access to the bolted connection of the gearbox support opens. The bolts must be unscrewed, and in case of scale formation or oxidation due to high temperatures, the place should be treated with special chemicals.

At the next stage, the bulk of all operations will be carried out from the bottom of the car. Watch friends a good video plot of checking the oil level in the Renault Logan gearbox, as well as topping up and changing the oil .... It is necessary to carefully remove the subframe and firmly fix the steering rack. This may require steel wire or a large diameter clamp.

Subsequent actions to disconnect assemblies or individual parts should also be carried out using a special chemical agent to facilitate the unscrewing of bolted and nut connections. It is necessary to dismantle the stabilizer links and disconnect the carrier rail from the subframe. From the side of the engine location, ball joints, steering tips and the main support are disconnected switching boxes gears. With a gentle movement, the subframe itself is removed.
