We replace the fuel filter for Renault Megane 2 and 3

It is difficult to imagine how much fuel a car “consumes” over the entire period of operation. And all this volume passes through a small device - a fuel filter. Renault Megane is available in several versions. Depending on the engine size, the design of the cleaning device also differs.

If we take Renault Megane 2, the year of manufacture of which does not exceed 2007, then the filter element (fine filter) is installed under the bottom of the car next to the rear wheel on the driver's side. Thus, Renauilt designers have achieved convenience when replacing this unit.

Models that have exceeded the 2007 year of production are mounted inside a unit with a pump and sensor

The third gasoline generation of Megan is no different from such models, therefore, the principle of their maintenance is similar.

In cars with diesel engine options, they didn’t go crazy and left the same fuel filter installation scheme.

Fuel filters for Megan 2 diesel have the original coding 82 00 186 218, 8200780950, 8200416942, 77 01 061 577, which corresponds to analogues:

These filters are available with a water separator and a water level sensor; there is a drain plug in the lower part of the housing.

1. The fuel filter is located on the driver's right side behind the front right wheel. It is recommended to place the right side on a jack, place a reliable support, and remove the wheel and wheel arch liner. The location of the filter can be seen more clearly by removing the fender and headlight.

2. It is better to get to the filter from the wheel side. We remove the protection. It is fastened with clips around the perimeter. Carefully pull out the clips and move the protection aside.

3. Now we’ve reached the filter housing (diamond). It is necessary to remove the filter housing mounting bracket. The fastening screws are indicated by arrows.

Location

It’s worth noting right away that in Renault Logan 1.6 and 1.4 the replacement is carried out in a not entirely identical manner. The difference between these machines is only in the location of the filter element. One more nuance. The fact is that cars with a power unit capacity of 1.4 liters are still produced to this day. As for the Renault Logan with a 1.6 engine, this power unit was no longer used back in 2006.

So where is the required element? If we talk about cars that went on sale after 2006, then you need to look for it in the fuel tank. It is noteworthy that it is installed together with a gasoline pump.

If we talk about earlier models, everything is a little simpler here. The filter is located in the place where the tubes through which the fuel moves come out of the tank.

. The fuel filter was installed separately on the Renault Megane of the first phase, i.e. year of manufacture of the vehicle before June 30, 2006.

The fuel filter in the second phase is located only in the tank and can be replaced together with the pump (if desired, a separate mesh).

On cars 2006 and even 2007, there is a fuel filter outside the tank - to determine its presence, you need to look under the car.

This report uses a KL72 fuel filter, its diameter is slightly smaller than the original, so I had to wrap a little electrical tape to fix it tightly in the mount. Try to buy the original or a suitable analogue (see codes above)

To make it easier to replace the filter, it is better to use a pit or lift.

To remove the filter, you need to press the square green clips (two on each side)

Pay attention to how the old filter is installed (direction of the arrows)

Remove the old filter from the mount, insert a new one, do not forget to take into account the direction of the arrows on the filter

Roughly speaking, gasoline “moves” through the filter from the front of the car to the rear.

Signs of a fuel pump malfunction

Before it breaks down, a worn-out fuel pump exhibits signs that indicate it will soon need repair or replacement:

1. Difficulty starting the engine. This requires more than one attempt with a long cranking of the starter. This could be a problem with the battery or the starter itself, which cannot crank the engine. But, if the problem does not go away when starting on a hot engine, the cause is the fuel pump.
2. One of the earliest signs of problems is a spontaneous change in the sound of the engine, and then its restoration for no apparent reason. At the same time, the engine itself operates stably, does not fluctuate, and has no extraneous noise.
3. Reduced power. When you press the gas pedal, the car accelerates more slowly and responds with some delay. This is especially noticeable when overtaking or driving downhill. This sign is not so clear, since the reason for this behavior of the car may be bad gasoline or problems with the ignition system, for example, broken high-voltage wires.
4. After turning the key in the ignition, you should hear the sound of a pump pumping fuel into the system for a few seconds. If it is not there, this clearly indicates a breakdown of the pump itself or the electrical circuit supplying it.

Hi all! I decided to change the fine fuel filter on my Megan... I ran into a problem, the filter is in the tank and is part of the fuel module of the car... The factory regulates the replacement of this filter and pump at 120,000 km. Original from 12000 rub. China is cheaper... I took the filter outside and now I can change it without any problems even every day... To do this I had to intervene a little in the design of the fuel module...

We connect all this under the seat and put it in a niche.

It is possible to install a filter under the hood, directly in front of the ramp, then you will only need one hose and two fittings for 90. I bought everything at the VAZ spare parts store for the amount of 1,500 rubles.

As a result, the car came to life, the internal combustion engine runs smoother, and pulls better under load conditions. Well, the consumption will naturally become less... Guys, the rubber was rubbish, it was enough for 2 days, I replaced it with plastic (cut from an antifreeze canister), sanded the surface of the patch and the pump, applied liquid welding and tightened the screws.

The welding dried for about 15 minutes, and then everything fell into place.

I hope my experience will be useful to you. Have questions ? Write, I will describe in more detail. As a result, after 10,000 thousand, the pressure began to disappear... after thinking a little, I converted it to a VAZ module... 100% solution to the problem, checked... it’s described in my blog.

Replacing the Megan 2 fuel filter: step-by-step manual

Manufacturers recommend changing the fuel filter on a Renault Megane 2 car every 15 thousand kilometers. However, if this part of the car becomes clogged, it is necessary to do this much earlier. The first sign of problems with the filter is the car jerking at low speeds or high gears.

Its main purpose is to delay foreign impurities and prevent them from entering the fuel system. Thus, the barrier protects the car engine from clogging and increases its performance.

Even a novice motorist can change the filter on Renault Megane 2. The whole process does not take much time and does not require special skills.

However, in cars produced in 2007 and 2008, it is different and also depends on the type of engine fuel: gasoline or diesel. In this article we will present a step-by-step manual for replacing the Megan 2 fuel filter, and will also provide you with the corresponding photo and video.

Instructions for replacing the filter

On Renault Megane car models with a gasoline engine, produced before 2007, 2008, the filter is found outside the tank. To find it, you just need to look under the car. It is best to use an overpass or a lift to install the part on a 2007, 2008 car. You can remove the worn part by pressing the square green clips, as indicated in the photo.

Next, simply remove the barrier and install a new one, not forgetting the direction of the arrows indicated on the filter. For understanding, the arrow on the part indicates how gasoline moves through this part: in the direction from the hood to the trunk. We fasten the fuel hose clamps until we hear a click.

All the details of the process can be seen in the video.

Replacing the fuel filter for a diesel engine

Initially, you need to remove the right front wheel and the part of the fender liner located closer to the front area of ​​Megan’s car. Lift the filter up and remove it from the bracket. Afterwards, turn off the power by lifting the latch and pulling the cable back, as shown in the photo.

Then we slightly swing the connector from side to side and pull it up, thereby disconnecting the fitting from the pipe (the one through which fuel enters the filter and the one through which it flows out of it).

In the upper area of ​​the barrier, unscrew the screw with a screwdriver. We are replacing the seal on it. We remove the top cover, remove the old barrier and install a new one. We assemble all the parts in reverse order and install the structure in the car.

Remove the rubber cap from the drain and pump fuel from the tank to the barrier. To do this, you need to press several times on the coolant bulb, which is located under the hood, behind the reservoir. After the fuel flows through the drain, screw on the rubber cap.

Well, to check the correctness of the work done, start the engine.

The video will help you avoid mistakes in the process.

Subtleties of filter replacement for second generation models

The barrier for the second phase (for models 2007, 2008) Renault Megane is located in the tank and has a different installation procedure. It is replaced as an assembly with the pump, or you can replace only the mesh, which is the barrier on the 2007, 2008 models.

• Using long-nose pliers and a chisel, remove the latches from the fuel pipes.
• Then we take out the fuel pump itself. We remember the location of the minus and plus and remove the terminals from the fuel pump motor.
• We dismantle the bottom cover, and then the mesh barrier.
• Rubber rings from the previous pump are put on the new one, after which it is installed in the housing and the fixing bolt is tightened.
• A new tube prepared in advance is pulled onto each fitting up to the second mark.
• We install the mesh barrier and fix the terminals in accordance with the poles.
• Finally, we screw the union nut, put the rubber ring of the cover on the fuel pump, fittings and connector.
• In the video below you can follow all the features of this process for the 2007 and 2008 models.

A correctly executed algorithm of actions will prevent interruptions in the fuel supply and problems in engine operation.

Rules for choosing consumables

It is not recommended to restore the old cabin filter, as this part cannot be repaired. Suitable for Renault Megane 2 cars:

1. Single layer systems. They completely eliminate poplar fluff, dust, soot, pollen, and insects that enter the vehicle interior.
2. Double layer filter. Eliminates unpleasant odors and toxic gases from the interior.
3. Three-layer device. Capable of performing the functions of single- and double-layer cabin filters simultaneously.
4. Combined systems. This is a compact and convenient installation that ensures effective removal of various contaminants from the interior.

Renault Megane 2 can be equipped with a variety of filter systems. Their choice depends on the degree of pollution of the car and the financial capabilities of the car owner. The most popular analogues of the Renault Megane 2 filter include:

1. The installation is manufactured in Germany and is characterized by high build quality. Thanks to the presence of a high-quality plastic frame, a tight fit of the equipment to the walls is ensured. Despite the fact that the length of the filter system is shorter than that of the original, it does not allow untreated air to pass through.
2. Citron. This model combines low cost and excellent technical characteristics. When using the device, high-quality filtration of air in the cabin is ensured even when driving a vehicle at a speed of more than 100 kilometers per hour. The manufacturer produces a carbon analogue of the filter, which not only provides air purification, but also eliminates unpleasant odors. The device has a reliable casing and is resistant to mechanical damage.
3. MANN-FILTER. The German manufacturer produces several types of filters. Nanofiber is used to make the filter element, which ensures high-quality purification of polluted air. Model 1829 consists of a regular, carbon and antibacterial layer. Thanks to the three-layer system, high-quality air purification and neutralization of foreign odors are ensured. Thanks to the thinness of the plastic in the bending areas, convenient installation of the device is ensured.

Their choice is made depending on the preferences and financial capabilities of the car owner.

• At the first stage of work, in order to get to the fuel filter, we lift the car with a jack or drive it into an inspection hole.
• On the right side of the rear of the bottom we find the fuel filter. Using a special liquid “WD-40”, wipe off all the dirt with a rag.
• We install a container under the cleaning element to drain remaining gasoline

• We connect the wiring harness block to the fuel module cover connector and the wire terminal to the negative terminal of the battery.
• To fill the system with fuel, start the engine. In this case, for 2 - 4 s you will hear the clicking sounds of the operating fuel pump. When the pump turns off, check the tightness of the connections of the fuel hoses and filter. We replace the tee and fuel pipe with damaged tips, faulty clamps and a filter with a leaky housing with new ones.

We replace the fuel filter on Renault Megane 2 and 3

The fuel filter is designed to retain foreign impurities and prevent them from entering the fuel system, protecting it from clogging and increasing the efficiency of the engine. The importance of this node is very difficult to overestimate.

Replacing the fuel filter for Renault Megane 2 and 3, despite its importance, the process is quite simple and even a novice car enthusiast can do it. It is necessary to replace it before the deadline specified in the instructions that come with the machine, because in our conditions the filter becomes unusable much earlier.

Replacement with Megan 2

Replacing the barrier on a gasoline engine and a Renault Megane 2 diesel engine is very similar, so we will consider everything using the example of only a gasoline engine.

Some features of the pump replacement work

When disassembling the Renault Megane 2 fuel pump, it is necessary to mark the lower cup so that during reassembly you can install it in the same position and correctly position the float after assembly. To dismantle the lower cup, you just need to lightly hit its rim with a hammer, after which it will come out of the lock. Do not strike the cup where the fuel level sensor is mounted.

After removing the lower cup, the fuel pump mesh is cleaned. It should be visible, if the mesh is clogged, this may be one of the reasons for the deterioration of the fuel pump.

When repairing a fuel pump, you need to check the operation of its electric motor. To do this, connect the positive terminal of the battery instead of the turquoise wire, and the negative terminal instead of the black wire. If the engine starts, it is fine. Such a test is necessary if, after turning on the ignition, the pump does not pump fuel with a characteristic sound.

The fuel pump and pump of the Renault Megane 2 are at risk after 100 thousand km, so you need to monitor their condition. These components ensure fuel supply and normal engine operation. If there are doubts about the normal operation of these systems, the problem must be solved immediately, otherwise this will lead to major problems and high costs for car repairs.

Seal

When is repair necessary?

If you do not replace the outdated filter on time, the driving performance of the car is significantly reduced and there is a risk that its other components will fail. The need to replace the filter system arises due to its clogging. In some cases, a car filter fails due to wear and tear. This often happens if the car’s mileage exceeds 15,000 km.

Some motorists decide to take advantage of such a widely popular service as replacing the Renault Megane cabin filter when the season changes. Consumable parts should be changed more often if the car is operated in severe weather conditions, for example, during sandstorms. If you are in a region where there is a lot of dust, then the filter should be replaced at least once every 7-10,000 km.

There are currently many filter options available on the market. Products vary in quality and cost. However, the most reliable are the original filters. In addition, the cost of purchasing them quickly pays off, since, unlike analogue ones, they do not have to be changed often.

Price, originals and analogues, article number

In order for the car engine to perform its functions efficiently, Renault advises purchasing only original spare parts. But, most car owners, if replacement is necessary, still buy less expensive non-original parts and components from other manufacturers. This is not surprising, because the cost of the spare part plays an important role for the driver of the vehicle.
