Diesel coolant flow

dean68uk · Jul 11, 2010

Looking at the RAVE pictures trying to work out out if my thermostat is working ok or even fitted. looks to me like the thermostat is fitted to stop water entering the head from the radiator. When looking at the engine the right had hose heats hot quickly. Is this normal?

P38 BMW diesel or Classic? What`s the problem? What`s the temp gauge doing?

Sorry P38 DT. Temp is halfway normally, but drops back to a quarter on the motorway or if you put the heater on.

Thermostat stuck or missing

I`d agree with that. Should go from cold to half way mark in few minutes/ coupla miles and stay there. Missing or stuck open.
Don`t wanna panic but if missing, ask yourself why? Sloppy maintenance/owner or trying to hide over-heating probs? Prob just failed in safe open position.

Yeah was thinking why myself looking at all the overheating threads! Oh dear
