str8_6 270 Report post Posted January 26, 2010 (edited) Evening all, Getting the fan clutch replaced in a few days as the car is running hot in traffic, fine when on the move. Noticed a couple of times in recently warm weather after switching the car off and coming back (say 2-5 mins later) the temp gauge reads 3/4 and moves back down to normal (half way) once started. My e34 M50 used to do the same on really warm days and I was told it was "normal..." Does anyone else experience this. I'm hoping the new fan clutch will help or sort it since the temp is erratic at the moment anyway. Could there be air in the system? Car is an e30 325i Edited January 26, 2010 by str8_6 Quote Share this post Link to post Share on other sites
SIR E30 68 Report post Posted January 26, 2010 Its because the water pump stops turning when you shut down the motor and the water inside gets nice and toasty, when you turn it over again it starts up the cooling system and brings the cooler water back around.
