Hello,
I have a 1979 300SD 5 cylinder diesel in awesome shape. I just started having a heating problem and I had the cracked thermostat replaced. Last summer the thermostat ran at about 40-50c and now its running at
90 degrees.The fan in front of the radiator isn't coming on. The air conditioning blast out cold and the heat blasts out heat.
Is the fan supposed to run at all times? If yes, what should we be looking for as the cause for the fan not running?
I am also looking for a mechanic in the east end of Toronto.
Thanks Judy
