Hi Guys

I want to change the viscous fan to an electric fan on my E36 328i. I have heard that this can be done. What is involved and what id required to do this ?

Thanx

Thanx Don !! Your the best.

Know, does anyone know of a place in PTA that can do this, or do I need to make an appointment with Gizmo ?

Viscous fan is connected directly to the water pump, creates extra resistance, whereas the electric fan is completely independent.

I've simply removed the viscous fan without bothering with an electric fan.

The air conditioner's fan already streams air through the system.

So far so good - make sure your car's aircon and coolant level sensor works..!

I would really not recommend this.

It is a border case, and therefore if you get stuck in crazy traffic on a 38deg day, you will have problems

I added the electric fan diy to my original post.

Better torque maybe half a kw too.

I was told this as well.

It can be done. The Fan Delete Mod seems common in some circles. But you cannot simply remove the viscous fan and coupling only. You also need to replace your thermostat with an 80 degree item (BMW p/n 11 53 1 466 174). Then replace your radiator fan swith with the 80/88 degree on (BMW p/n 61 31 8 376 440). It is also advisable to change your thermostat housing with the aluminium one you can buy from Goldwagen.
Lastly, you need to add 2 bottles of Redline Water Wetter to your normal antifreeze mix. This greatly enhances the ability of your coolant to absorb heat out of your engine castings.
Then make very sure your electric aircon fan, wiring and fuse is in 100% condition. You will have no backup if it fails.
I plan on doing this to my car soon. Worth a few BHP on a hot day.
