    hi all, i have a bmw e36 318is and want to convert from the viscous fan to an electric one, i have a complete spare 318is with the fan and radiator and loom and fusebox, etc, is it easier to transfer all the loom and radiator and stuff to the car, or should i run a separate wiring loom and fuses and relays for the electric fan???? and is there a wiring diagram for this system out there??

    thanks in advance for any help

    I took my fan off a week ago and have had no problems whatsoever. Even with the aircon on...needle stays right in the middle and doesn't move, even when waiting in traffic.

    But, I have the electric fan on front. Take the fan off the other car, including all the wiring. I would put in a new relay, taking power direct from the battery with the relay triggered from the temp sensor. When you take off the fan from the other car, look for where the harness connects to the temp sensor - you will need to tap into the same place on your car to trip the relay.

    Don't expect huge increase. The car will reach operating temp more quickly, which is good in a cold climate. A small increase in horses, but can't really measure it. Main benefit is being able to remove the plastic cowling and getting much greater access to the engine bay.

    Let us know how you get on...
