I told it for 5 cylinder 2.4 liter engine

Hi
I think you replaced wrong parts.
Thermostad is made by aluminium and locate behind egr and trhottle body.

Is this normal when i start engine then both radiator fan working slowly about 20 seconds, even when engine is cold and outside is also cold.

Is this possible to activate exta gauge to see coolan temp on dachboard? If yes, then how ? S80 2010

Ther might be several problems.
* Chek coolan temp with diagnostik appliance, if this low even you been driven dard. its probably problem with thermostat.
* Maybe coolant sensor is dead, it causes fan working while they shouldn t work
* Maybe fan controll modul is dead,
* Maybe cabin filter is dirty

Hi
First suggest is to chek coolant temp with diagnostics appliance, if coolan temp is low ( less than 80 degrees) after you have drive at least 20 minutes, probably is problem with thermostad. Also wight be problem temp sensor which controll fans. Does fan working all the time?
