Renault Logan heater radiator replacement

Today it is impossible to imagine a car without heating. At least in our harsh climate. If the stove in the car fails in a thirty-degree frost, that car will pass very close. This applies to all cars, and Renault Logan is no exception. The heating radiator of this car can be a real headache for a motorist. But luckily it can be replaced and you can do it yourself. And we will dwell on this in more detail.

Diagnostics of the stove radiator malfunction

Replacing the stove radiator may be necessary in two main cases:

• radiator leak Signs of a leak are the appearance of antifreeze on the front carpet (under the feet of the driver and passenger), as well as a drop in the coolant level in the expansion tank;
• inefficient operation of the radiator caused by its clogging. At the same time, when the engine warms up to operating temperature, the stove heats up weakly, the air flow heats up only at high engine speeds.

If these malfunctions are identified, you should not worry, you can do the work of replacing the stove radiator with your own hands in garage conditions.

Appointment of the heater radiator for Renault Logan

The Renault Logan heating radiator performs the same function as the main radiator of the engine cooling system: it serves as a simple heat exchanger.

Heating radiators for Renault Logan are usually made of aluminum

The principle of their work is simple. Antifreeze heated by a hot engine enters the stove radiator, which is intensively blown by a small fan that blows hot air from the radiator grilles into special air ducts. Through them, hot air enters the interior of the car and heats it up. The intensity of heating is regulated by changing the fan speed and changing the angle of rotation of a special throttle valve for taking cold air from outside.

In a Renault Logan car, the heating radiator is a conventional heat exchanger

The location of the radiator of the stove in Renault Logan

The stove radiator is located under the dashboard, almost at the level of the cabin floor, at the driver's right foot. It is not possible to see it, as it is closed on all sides by plastic panels and upholstery. And to get to the radiator and replace it, this entire lining will have to be removed. The main part of the work on replacing this device is connected with the dismantling of the lining.

The location of the radiator of the stove in Renault-Logan

The stove (heater) in a Renault Logan car is located in front, in the center of the cabin, under the dashboard. The radiator is located inside the heater from below, but you can see it only by removing the plastic decorative trim.

Heating device "Renault Logan"

The diagram shows the main elements of the Renault car heater, the location of which every driver should know:

1. Distribution block.
2. Radiator.
3. Heating pipes.
4. Cabin fan resistor.
5. Left front air duct for heating the footwell.
6. Air recirculation control cable.
7. Air distribution control cable.
8. Air temperature control cable.

Step by step guide

1. Remove the lower cover from the latches and remove it. We take it as shown below and discard it to the sides (towards the doors).

2. Remove the clip to push the carpet out of the way. The clip can be pry off with a flathead screwdriver.

3. We got access to the bolts of the bar holding the rack, and the torpedo is already attached to this rack. To access the radiator, you need to remove the bar.

We unscrew the two screws that are marked in the photo below.

4. Squeeze the sides and insert the clip marked below. This clip holds the wire harness.

5. Remove the ignition lock connector from the bracket. Press the latch and tighten.

6. After removing the connector, we have access to the nuts that hold the bar. We unscrew the fastening nuts and remove the bar.

When you remove the bar, take your time, you still have to disconnect the wiring harness.

7. Having removed the bar, we got access to the heater radiator.

8. Unscrew the three Torx T20 screws.

9. Putting a rag under the nozzles, pull them out.

10. We bend the latches and remove the radiator.

The latches literally do not bend, you just need to press them and remove the radiator.

11. Before installing a new radiator, it is recommended to blow out the seat with compressed air or clean it manually.

12. Replace the sealing rings on the pipes. After replacing the rings, lubricate them a little so that they easily fit into the radiator.

13. Install a radiator.

14. We fix the radiator with two screws.

15. We insert the pipes into the radiator and fasten the locking bar with a screw.

Make sure that when tightening the screw, the sealing gum does not bite.

16. Next, fill in the coolant, pump the system, remove the air. Check for leaks in pipes.

17. If there are no leaks, install a metal bar and the rest. I don't think you need details.
