So my 318is(m44) is electric fan. Am I good? Is this the same as having the fan delete mod in an M42?

ill open this thread again instead of opening a new one..

i bought the FDK from understeer..
and it came with 2 peices, the thermostat with the gasket
and the switch with the thread cap.

now besides the water wetter, distilled water, and the coolant water, what will I need?

i see many people installed an electric fan, and many didnt.. do I need it?

will i need to change my coolant sensor?

thanks!

what you have is good enough, although..... i doo recommend getting an electric fan just for extra cooling. Your electric fan is meant for your a/c and doesnt put out enough air flow. So in a hot day stuck in traffic, you wouldnt want to risk it. Besides an electric fan goes for what, more or less 150-250..

I never installed the electric fan and have never seen my temp gauge go over half way.

I removed the clutch fan (it exploded actually), replaced the rad, put in a new OEM thermostat, left the OEM temp sensor, new coolant, and replaced my seized AUX fan. No water wetter, no spal/electric fan.

I've also had no overheating issues, even with the A/C on and crawling through bumper-to-bumper morning rush hour traffic on the 401 through Scarborough.

Hence ac condenser fan / aux fan, same thing lol so your fan is on if your ac is on, so of course no problem, but more then less...im to lazy to say what i have to say, im just gonna eat my lunch and read aha

The aux fan also comes on via the temp sensor, even if the A/C is off. I'm not sure what you are trying to say. The point I was trying to make was that even with the a/c on, which adds heat to the coil directly in front of the rad, the aux fan seems to provide sufficient air flow to cool everything even without the lower temp sensor, lower temp thermostat, or water wetter.

i just replaced my thermostat last december..
do i need to change it again with the one they sent with the package?
because if i dont replace it, its a 10 mins job.. no need to bleed or change the coolant.

ac on or off wont make a difference.

All I'm saying is an electric fan...$200, or 3g's+ for rebuilding you head.

To everyone saying they dont need it or theyve had their cars without it for 20 years, thats great! My car overheated on me 2 summers ago in traffic. All in all having the head professionally welded, cometic head gasket, arp heads studs, and all the labour, cost me $3300. So you figure out if it's something worth cheaping out on

A good tested used motor is cheaper then that!!!

Yes redundant systems are always good, but not always needed. If you over heated you aux fan must have failed, in traffic and you did not notice the temp gauge going up. May have been avoidable but who knows.

Wow, but isnt welding the head bad, just incase u had to change the internals or soemthing... also.. i agree, first thing i did when i bought my bimmer was buy a spal fan off of a member here, it was furious....

And thats also if u just replace the clutch fan with a better fan you wont have a problem, just remember, engines need a certain temperaature to run at, and that is the only reason why im not just hooking up my spal fan to just run when the car starts....

Also i really need help, what can i do and how do i make it so that i can control when the fan comes on and off... the cheapest way please!! i got alot of time to mess around, just not enough money to use
