Hey @Kalsang Dorjee. Thanks for the great video! I have a similar problem - the engine heats up dynamically, but on top of that there is a lack of heating in the vehicle. Was it similar in your case? I assume that if it was the thermostat it would be very strong heating inside the vehicle - in my case it is cool air. I assume that it is the water pump - what do you think - how was it in your case?

Do you know where coolant temperature sensor located

Did it fix the problem and did the fan was working when the thermostat bad

Saying it but not showing it… what’s that point of a video? 🤔

All I saw was engine.
