Land Rover Range Rover Sport, the heater is not hot because there is this thing in the water tank

The weather is getting colder and colder recently. Friends who go out to use their cars must pay attention to keeping warm. After starting the vehicle from cold, warm it up for a while and turn on the heater when the water temperature reaches the midline, which is 90°C; If there is frost on the glass, set the air conditioner to defrost mode and it will be fine in a while. I encountered a Land Rover Range Rover Sport today. The owner reported that the heater air was not very hot. Even after driving the vehicle for 40 minutes, he could not feel the warm air blowing out.

After entering the store for inspection, it was found that by stepping on the accelerator and setting the idle speed to 3,000 rpm, the temperature of the warm air blowing out of the outlet can reach about 50℃ after running for a period of time. After releasing the accelerator, the temperature will also increase accordingly. falling. In this case, it is obvious that the circulation of antifreeze in the heater water tank is not smooth, resulting in poor heating effect of the water tank.

Since the car's heater water tank is installed in the dashboard of the cab, replacing or inspecting the heater water tank requires dismantling the dashboard, so this car needs to disassemble the dashboard

To disassemble the instrument panel, you need to remove the accessories on the instrument panel: multimedia system, instrument system, center console control system, etc. Only by removing these accessories can the instrument panel's skin be removed.

First, let’s take a photo after taking it off. Pay attention and don’t be surprised.

The dashboard was no longer visible in the dismantled cab, leaving only some vehicle wiring harnesses and the steering column of the steering mechanism.

Separate the air-conditioning blower assembly from the instrument panel

This is what we call the instrument panel assembly, and the heater water tank is inside this assembly

After removing the heater water tank, we find a clean place and pour out the residual antifreeze inside to see what comes out.

We poured out a lot of water and some debris from the heater water tank

These magazines and debris will play a decisive role in the circulation of antifreeze in the water tank. , in severe cases, it may even block the internal pipes of the heater water tank, causing the heater water tank to be unable to perform its proper heat dissipation function.

So when we replace the vehicle's antifreeze, we must choose the right antifreeze to replace. When replacing other parts of the vehicle's cooling system, it is also recommended to choose original parts for replacement to avoid problems. This situation.
