Hi,
My 2007 CL500 is currently blasting its rad fan when it shouldn't be. On absolute cold start , as soon as the car is unlocked it will spin up and turn on n off every few mins regardless of temperature.
Its winter here and the AC is not being used so I have kinda ruled the compressor out as the problem . I get accurate temp readings on the dash (around 85c at operating temp) so my next guess is the coolant sensor .
Im fairly new ro Mercedes ownership , so I cant quite figure out where the sensor is. The part is fairly cheap at ~£15 but can anyone suggest on how to find and change it? And weather or not I can get away with changing it without draining the coolant?
Or if anyone can suggest any other things to try.
The final option would be the fan relay which I've learnt is part of the fan assembly so means a whole fan change at about £500 , so I'd like to eliminate anything else first .
Thanks advance
