In Reply to: Replacing the belt driven fan w/ an electric one.. posted by Erik Brannfors on June 10, 2001 at 22:04:36:

Mine is a German car(imported to the UK) and has just an electric fan as std. basically there is a temp sensor switch at the bottom of the radiator which activates it. Aircon cars (like mine)with this setup have a three way switch I believe. I cant go into detail here as I`m not realy as techy as I`d like to be - ha ha.

There is an easy alternative! The previous owner of my car must of had problems with the setup and decided to wire it directly to the spare switch on the dash, so I just switch it on when I want it on. I guess in HOT countries this would be a real pain though. I find it okay but u HAVE to remember to keep an eye on the temps in traffic. I have had my original system looked at and it worked again ONCE then blimmin` failed after that so Im back switching it on manually for now (have been for the past year - ha haha)



This would be on a 1990 M3. I have searched the archives, as well as I could, I guess. I saw alot of posts saying that getting rid of the belt driven fan and going to an electric setup is good, and I agree. However, I have not found a description of how to wire it, if there is an "accepted" method and list of parts for this project. Thanks.

Erik
