Renault Fluence Stove Motor Replacement

The stove is an integral part of the comfort of any car. The French car manufacturer Renault knows a lot about this. Heating of cars of the Fluence family is generally reliable, but failures still happen. Drivers note the lack of operation of the stove already at the beginning of cold weather. Suspicion usually falls on the stove motor. Due to numerous requests from readers, we have provided detailed instructions for replacing it.

Replacing the Renault Fluence stove motor.

The first step is diagnostics

Before replacing the heater fan, it is necessary to diagnose the system as a whole. It is necessary to exclude breakdowns of other components or errors of actions during the maintenance of the climatic section of the car. These include:

• Incorrect selection or errors in the rules for mixing antifreeze. This vehicle requires G12+/G12++ red coolant. As a temporary solution, it is allowed to fill in yellow antifreeze No. 13. But blue and green varieties are prohibited.
• Coolant leak. They occur due to cracks in the supply pipes. If the problem is very fast, the radiator assembly is entirely to blame. Motorists tend not to repair the radiator, but to replace it entirely by gravity.
• Residual fluid deposits. Another big mistake. Each antifreeze has a certain expiration date. After the end, its properties change. Antifreeze becomes cloudy, a kind of sediment appears. Subsequently, it is deposited on the walls of the radiator and pipes, making it difficult for coolant to enter. Efficiency is reduced. Also, the reason for this scenario is low-quality liquid from the sidewalk.
• Possible failure of the sensors or the entire electronic control unit of the stove.
• And the banal inattention of the driver closes the table. Often, motorists simply forget to update or add antifreeze to an acceptable level.

If the controller is working, but the stove does not work, you need to check the motor. Diagnostics consists of several stages: disassembly, cleaning, condition assessment. Then there are two options: damaged parts are changed along with the renewal of the lubricant, then reassembly and installation is performed. And in the second case, the engine becomes unusable and it is changed. Let's consider everything in order.

Motor test

1. If there is a cabin filter in the package, check its integrity and level of contamination. Change it every 15 km. And if a hole from a sharp stone is found in it, it is immediately changed. Here they already remove the motor from the stove and remove particles that interfere with the work.
2. Next on the agenda is a system of fuses and resistors operating in different modes. The part is located on the mounting block on the left side. Usually there is a driver's seat. The presence of traces of soot, a violation of the insulation of the wires indicates a short circuit. The blown fuse and resistors are replaced with new ones. If everything is in order, we look for the problem further. It's time to remove the engine.

How to remove the stove motor

For the job, you'll need different sizes of screwdrivers, a headlamp, brushes, and spare fasteners just in case. First of all, you need to disassemble the glove box. This step is usually not difficult. It is also necessary to disconnect the contacts for blowing the front passenger seat, the roof of the glove compartment, and its ventilation pipe. The next step is to lower and recline the back of the same passenger seat. It is necessary to position yourself so that the head is inside the torpedo under the passenger airbag. The pipeline must be removed. The driver's eye is equipped with a motor unit with a shock absorber and an air intake grille. Pry lightly with a screwdriver to disconnect the recirculation damper motor, then disconnect the chip. As a result, all grille fastening screws must be open, except for the top one with the nickname “for an hour”.

Now it's time to unscrew those screws and remove the grille. The goal is achieved: the stove motor is easy to get. The two screws holding it behind the impeller must be removed with a magnetic pick. Otherwise, they will get into the air filter, from where it will not be easy to remove them. You just need to take this part out and get access to the impeller. Turn it clockwise with both hands until it stops. Procedure completed. After removing the motor, it is cleaned of dirt and the diffuser and recirculation damper are washed. But due to the biased design, cleaning takes a lot of effort, so many drivers simply throw out the old dirty engine and install a new one. The assembly of the new heater motor is carried out in the reverse order.

Tips for last

Maintenance and replacement of the heater fan is scheduled for a weekend or holiday. For an inexperienced driver, a simple operation can take a whole day. At first, do the work under the guidance of an experienced friend or a qualified craftsman. But with the accumulation of knowledge and the development of skills, this procedure will no longer take much time. And every time you replace, think about your loved ones, who will appreciate your efforts to ensure comfortable winter trips.
