The main problems of the Renault Fluence car associated with the timing belt. Repair prices for Renault Fluence Other problems and malfunctions

At Renault Fluence, the timing belt is replaced according to the same principle as on most other foreign cars. As you know, the timing belt must be changed every 60 thousand kilometers or once every 4 years, even if the car has not left the prescribed mileage during this time. The fact is that rubber has its own limited service life and if it is not replaced at a certain point, this can lead to serious consequences.

Renault Fluence chain or timing belt?

When timing for timing replacement is approaching, it is important to know if a chain or belt is installed on your vehicle. Renault Fluence owners need to know that the type of drive - chain or belt - directly depends on the modification of the Frenchman. On older cars, a timing belt is installed, on a new engine there is a chain. It is also important to know how long to replace the timing belt.

Renault Fluence: when to change the timing belt?

• The frequency of belt replacement is every 60 thousand kilometers or every 4 years
• The chain serves about 130 thousand kilometers

How is Renault Fluence timing replaced?

The sequence of the timing belt replacement process for Renault Fluence depends on the type of engine - gasoline or diesel. But, in general, the stages of replacement on cars with different types engines are similar and differ only in some details. Replacement can be done on your own or use the services of specialists.

Let's consider how to change the timing belt using the example of a car with a K4M 1.6 liter gasoline engine. Before starting work, you will need to purchase a Renault Fluence timing kit. The kit consists of the actual belt, bolts and roller.

Renault Fluence: do-it-yourself timing belt replacement

Removing the old timing belt:

• Raise the car
• Dismantle the engine protection and remove the right fender liner
• Raise the engine with a jack, resting it on a pallet near the crankshaft pulley
• Unscrew the upper mount at the engine mount, unscrew the supporting support
• Disconnect and move aside the fuel line fitting
• Remove the camshaft end cap at the intake valves (it is easy to find - this cap is the largest in diameter)
• Engage fifth gear, then slowly rotate the wheel drive to the hub clockwise with a key of 30 (view from the engine compartment)
• Align the shafts along the intake camshaft (where the plug was removed) in one line with serifs - in this case, the serifs must be located below the axis of the camshafts
• Unscrew the two nuts and three bolts with a 13 wrench, after which it will be possible to remove the upper protective cover from the timing belt
• Remove tensioner and alternator belt
• Put it back in fifth gear, after that the partner must press the brake all the way
• At the same time, unscrew the bolt securing the crankshaft damper pulley with an 18 wrench and remove the pulley
• Remove 4 bolts from fastening the lower plastic timing belt cover and dismantle it
• Fix the toothed pulleys of the camshafts to prevent scrolling - this can be done using two washers and an M10x50 bolt with a nut (it is also recommended to make additional marks on the cover body and on the pulleys with a marker)
• Also, before removing the timing belt, it is necessary to mark with a marker on the engine housing and on the crankshaft toothed pulley
• Unscrew the key on the 13 timing roller nut and remove the belt
• Unscrew the bolt with a key on T40
• Remove timing belt pulley
• Further, before removing the tension roller, it is necessary to note its position in order to correctly set the belt tension in the future.

Installing a new timing belt:

• Fasten the bypass, then the tension rollers
• It is necessary to fix the preload with a self-tapping screw, focusing on the position of the old tensioner
• The timing belt itself only needs to be thrown on the lower part on the crankshaft toothed pulley - this will simplify the installation of the belt on the roller
• Scroll the crankshaft through the wheel hub - in the process it is necessary to monitor the coincidence of the marks on the pulleys
• Install a new tensioner pulley with a self-tensioning mechanism for the poly V-belt drive
• Install the bottom plastic cover
• Reinstall the crankshaft damper pulley and secure it with a sufficiently strong tension with a new bolt with a thick washer (it is included in the kit) - during the procedure, you need to turn on the fifth gear again, while the assistant must press the brake pedal with force
• put on drive belt.
• Remove the fixing bolt and washers from the camshaft pulleys.
• Close the top cover (duralumin) of the timing belt
• Screw in the support support and the upper engine mount
• Connect fuel line fitting
• Insert a new plug onto the end housing of the intake camshaft cover
• Install the right wheel
• Remove jack

To check the correct installation of the timing belt on Renault Fluence, it is necessary to start the engine after all the procedures done. If it makes the usual smooth noise, then the replacement is done correctly.

Replacing the timing chain with Renault Fluence is done in the same way.

Raise the car, remove the front right wheel. We remove the engine protection and the right fender liner.

Using a jack, we raise the engine, resting on the pallet closer to the crankshaft pulley.

We unscrew the upper mount of the engine mount and the supporting support.

Then remove the end cap of the intake camshaft (which is larger than the others in diameter).

View with cap removed

Align the shafts along the intake camshaft (where the plug was removed) with serifs in one line, and the serifs should be located below the axis of the camshafts. Then you need to unscrew 3 bolts and 2 nuts with a 13 wrench and remove the upper protective cover of the timing belt.

Remove the alternator belt and tensioner pulley.

Again, put in 5th gear and ask your partner to press the brake all the way.

At this time, unscrew the bolt securing the crankshaft damper pulley with an 18 wrench and remove the pulley.

Unscrew the 4 bolts securing the lower protective plastic cover of the timing belt and remove it.

With the help of an M10x50 bolt with a nut and two washers, using the method as in the photo, we fix the toothed pulleys of the camshafts from scrolling, but for every “fireman”, be sure to make marks with a felt-tip pen on the pulleys and the cover body.

Before removing the timing belt, make a mark on the crankshaft sprocket and on the engine housing with a marker.

Then, with a 13 wrench, unscrew the nut of the timing tension roller and remove the timing belt.

Unscrew the bolt with a key on the T40 and remove the timing belt pulley.

Before removing the timing belt tensioner, mark the position of the tensioner so that the correct timing belt tension is set when replacing the roller.

Install a new timing belt.

First we fix the bypass roller, then the tensioner.

At the same time, we fix the preload with a self-tapping screw (we load the self-tensioning roller), i.e. the position that was on the old tensioner. You have to tinker a little with dressing the belt, which all the time strives to pop out. Therefore, this procedure is best done with an assistant. To facilitate the procedure for putting on the belt, the timing belt should only be slightly thrown over the lower part of the crankshaft toothed pulley, which will simplify the installation of the belt on the tension roller. After installing the belt, we scroll the crankshaft through the wheel hub. At the same time, we check the coincidence of the marked marks on the pulleys. If there is a discrepancy, repeat the procedure.

13. We install a new tensioner roller with a self-tensioning mechanism for the poly V-belt drive. We fix in place the previously removed lower plastic cover. We put the crankshaft damper pulley in place and fix it (with a fairly strong interference fit) with a new bolt with a thick washer from the kit that comes with the timing belt. At the same time, fifth gear is engaged, the assistant presses the brake pedal with force. Wear a drive belt.

14. We release the toothed pulleys of the camshafts from the fixing bolt with washers. We close the upper duralumin timing belt cover.

15. We twist the upper mount of the engine mount and the supporting support.

16. Connect the fuel line fitting.

17. We insert a new plug into the end housing of the intake camshaft cover.

18. We put the right wheel in place.

19. We release the engine crankcase from the jack.

20. We read a prayer, and ... we start the engine. Hearing the smooth noise of the engine, we smile, rejoicing at the work done!

Replacing the timing belt Renault Fluence 1.6 can be done independently, for this it is not necessary to involve specialists. But we will not beg the complexity and importance of this procedure, in order to do it, you need to try. It is worth considering the fact that an incorrect installation can cause a break, and these consequences can be called serious, since, most likely, after that you will have to do overhaul. The belt should be replaced in accordance with the regulations.

Preparing for a replacement

First of all, you will have the front front wheel on the right, for which you will have to raise the car with a jack. To ensure free access to all nodes, it is better to remove the fender liner. A wooden chock is placed under the car, and a jack is used to raise the engine to hang the mechanism. The jack under the engine sump should be placed as close as possible to the crankshaft pulley. Now you need to detach the supporting support. Then the fuel line is dismantled. After disconnecting, it must be taken to the side to the maximum distance - as far as the tube allows. All these actions must be done in order to ensure maximum accessibility to all timing units.

The Renault Fluence 1.6 engine has 2 camshafts. One controls the intake valves and the other controls the exhaust. Before starting the replacement, the caps will have to be removed from the shafts.

Attention! Before starting work, buy new caps, because the old ones are likely to become unusable, as they will be removed with a screwdriver, which will compromise the integrity of these plastic parts.

Now we need to ensure that the slots on the shafts are in a horizontal position, for this the crankshaft must be manually rotated to the desired position of the slots. After that, we can lock the shafts with a 5-6 mm plate.

The next step is to unscrew the pulley. To do this, we take the head at 18. It will be quite simple to do this, since the crankshaft will already be locked, and therefore the pulley will not scroll. Now remove the timing case. Only 2 casings - metal and made of plastic. Plastic is attached with 4 bolts. At this stage, many are faced with certain difficulties, since the cover is located next to the spar, which creates certain difficulties when unscrewing. Removing the metal casing will be much easier.

Replacement

Experts also recommend checking the condition of the pump, since in this state it is very clearly visible. Now we proceed to the direct dismantling of the belt. Its replacement may be necessary even if it is not torn, but has cracks or delaminations. The presence of oil stains on the belt is also considered unacceptable. If the belt is simply loose, it will only need to be tightened. To do this, the tension roller is loosened.

For tightening, the tension roller is rotated counterclockwise, for unscrewing - clockwise. In order to make it easier to remove the belt, you need to pry it off with a pry bar.

Assembly

Now the old belt has been removed, and you can install a new one. To do this, we throw it on the gears of the camshafts. The crankshaft gear must be locked. When the belt is in position, it must be tightened with a hex wrench. The belt tension must be optimal - the arrow on the tension roller must match the protrusion on the back of the roller.

Then the gas distribution casings are mounted. This action should be performed in the reverse order, that is, the metal casing is put on first, and then the plastic one. Now the crankshaft pulley is installed. The mounting bolt should also be replaced. As a rule, it is included in the delivery of the belt. Now you need to put on the attachment belt, install the engine mount and fuel line. Before installing the camshaft plugs, they should be lubricated.

Now the belt has been replaced, and after that it will serve you at least 60,000 kilometers.

Full maintenance Renault Fluence

Replacing the timing belt is one of the most important procedures during the operation of the car. To avoid the unpleasant and costly consequences that a sudden break in the belt entails (overhaul or installation of a new motor), it is recommended to change the timing belt in accordance with the regulations. For this mechanism general rules suggest replacement every 100 thousand kilometers.

Lacking the necessary experience for self repair this site, you should read articles and videos on this topic.

For a Renault Fluence car with an engine capacity of 1.6 liters, 106 hp. and a five-speed gearbox, the timing belt replacement algorithm involves the following steps:

Preparation for work

After jacking up the car, remove the front right wheel. For ease of access to various nodes, we dismantle the fender liner. Under the rigid support of the skirt of the car, you need to put a few bricks or a wooden chock that can withstand the weight of the car. With a jack, we raise the engine by the pallet to slightly hang the mechanism. The point of support of the pallet on the lifting platform of the jack should be located as close as possible to the crankshaft pulley.

The next step in preparation is to detach the upper pillow of the Renault Fluence motor and the supporting support. Next, we unscrew the fuel line and set it aside as far as the flexibility of the tube allows. This is done in order to further provide easy access to the timing unit.

The 16-valve engine has two camshafts - for intake and exhaust valves. Before starting the main work on replacing the timing belt on a Renault Fluence car, it is necessary to remove the plastic caps from both gas distribution shafts.

The caps will become unusable, since they are usually removed with a screwdriver, which violates the integrity of the plug. Therefore, before starting work, you need to purchase a couple of new plugs.

Each of the shafts has two grooves. We manually scroll the crankshaft by rotating the pulley bolt, and ensure that the slots on both shafts take a horizontal position. This is done in order to lock both shafts with a 5 mm thick plate. But before that, you need to stop the crankshaft itself, by setting homemade device, shaped like a bolt, into a special hole.

With the help of a head of 18 - the one that until this moment was used to rotate the crankshaft, we unscrew the pulley. The crankshaft is already locked at this point, so this action will not be difficult - the pulley will not turn.

The next step is to remove the timing covers - plastic and metal. They start with a plastic one, which is fastened with four 8 bolts. Unscrewing some of them can be problematic due to the fact that the cover is close to the body side member. After the plastic protection is removed, we proceed to remove the metal one, using the 13 key as a tool.

Main job

In addition to the rollers, you will need to remove the crankshaft gear. In the event that the part has stuck to the crankshaft, dismantling is carried out with a special puller. Otherwise, you can screw two bolts into the gear housing, and by pulling them with gas wrenches, remove the gear.

After the belt has taken its working position, we stretch it with a hex key.

The eccentric tension roller has an arrow, which, during the tightening process, should visually align with a small protrusion on the opposite side of the roller. This position indicates that the belt tension is optimal.

In order to visualize this process, you can find a corresponding video on the Internet.

After the pre-tensioning procedure, a test can be carried out that will show whether the belt has received sufficient tension. To do this, you need to remove the bolt, the locking crankshaft and the metal plate that ensures the correct position of both gas distribution shafts, as well as blocking them. We turn the crankshaft bolt clockwise, while simultaneously observing how the belt behaves. After one full turn, the ignition test can be carried out. The angle is considered correct if, after all the machinations, the special plate still fits easily into the grooves of both camshafts.

final stage

The casings of the gas distribution mechanism are installed in the reverse order - first metal, then plastic. This sequence is explained by the tightest fit of one cover to another at the junction.

The crankshaft pulley is installed. In this case, it is advisable to replace the bolt with a new one. Usually it comes in a kit that comes with a new belt.

After installing the pulley, the attachment belt is put on, the engine support is screwed on and the fuel line is put in place. New Renault engine camshaft plugs must be installed in place, after lubricating their edges with machine oil.

Summarize

Timing belt Renault Fluence on a 1.6 liter engine, power 106 Horse power successfully replaced and now, for at least 60 thousand kilometers, this mechanism will not cause trouble to the car owner. However, words cannot describe everything - more detailed information on replacement can always be obtained by finding on the Internet detailed video about this theme.
