Well, my car almost overheated in the same way before. After he fixed the fan he left is sitting for 30 minutes with the air on, but the temp gauge sat right in the middle. When he checked the fan, he used some tester, and did it right in front of me, the high speed would kick on but not the low speed. Was 100 bucks to fix, needed a resistor, and removal of bumper.
: Just today my 535i overheated again. Two weeks ago, and one year before, I had towed to machanic. Both times the thermostat was replaced. This time, the mechanic thinks its the radiator -- says that it has become less efficient because of build-up on inner piping. Could this be so?? (The problem has occurred during the summer, and only when I have had the a/c working -- placing extra burden on the system). Could the problem be the two speed auxillary fan not working at both speeds, or, the "clutch" instead?? Sure need to know soon -- the mechanic has ordered a $400+ replacement radiator (which can be returned) -- plus labor charges.
: Can anyone please suggest some 11th hour checks which should be made before replacing the radiator -- and later finding that it wasn't the problem? (Car maintains temp just fine when driven without the a/c on.) Many many thanks for your help asap. DJD/Louisville KY
