Car is overheating while idling or in stop in go. I heard the fan clutch screech when I started the car and figured the fan clutch had gone. Does an electric fan make much of a difference on the M42? I know for the M20 it doesn't make much sense but on a smaller motor I think it would, ALso what is the parts number and a decent DIY

Is your aux fan not working? I know by now many of them have blown resistor packs and stop working but if it's there why not use it? Get it fixed and while you're in there clear the condenser of debris. I think on a 4 cylinder, it's worth it to remove the fan clutch and install an electric puller fan if you are trying to free up the engine but if you daily the car and want reliable cooling...get a good fan clutch."I'd probably take the E30 M3 in this case just because I love that little car, and how tanky that inline 6 is." - thecj

Reliability is a concern especially since I will be moving to warmer climate

Would this be an appropriate replacement? http://www.ecstuning.com/BMW-E30-318...lutch/ES24490/

Have you done the test on the fan clutch yet?

To test the aux fan go to the temp switch at the radiator, and short two switch pins together when the car electronics are on.
GRN/BLK to BRN/BLK fires low temp mode
GRN/BLK to BLK fires high temp mode
If high temp mode works, fan works
If low temp mode works, fan and resistor work
If only high temp works, fan works but not the resistor
