Argh shows it only for the v6 3 series, unfortunately mine is a 318i ohh well thanks anyway

[mmclaren]

can anyone confirm if this is only a 6cycl mod or can i do it to a bmw 318i 94 e36 m43

I don't think you can do it on the 318. You could always just replace teh stock fan with an electric one, which has the same effect of the mod.

I have an M42 318 and I've done it. It is quite easy. Flex-A-Lite makes very good electric fan where you would mount to the back of the radiator. You would remove the stock clutch fan and then use an adjustable temperature control unit which you would probe into the radiator hoses. It would measure the temp. of the coolant and you can adjust when you want the fan to come on.

Here's a pic..



NeverLeaned, you can do it on any car which has an auxilary fan, but if you're worried about the engine overheating, it's better to install an electric fan. All E36's have Aux fans, I just removed mine because it blocks airflow from the front of the car.

Holy cow!
There is a huge opening in the engine bay right to the floor!
Is your car supposed to be that way?

that's what i was wondering, did you remove something for pic purposes used

i wouldnt do it...because most ppl think the stock fan blows air on the radiator when it actually draws air into the engine bay. and they replace with a fan that blows air against the radiator so the car actually runs hotter. even turbo cars only gain 1-2 hp but they run about 10-20 degrees fahrenheit hotter.

edit: unless you live somewhere really damn cold

Most people mount an aftermarket electric fan to still draw air through the radiator.

Whoever did that is a moron and installed it incorrectly. There's no way you're supposed to blow air onto the rad using the hot air from the engine, that doesn't make sense and wouldn't do anything! What's the difference between using an electric fan and a belt-driven clutch fan? They both blow or suck air depending on the way you install it.

My fan sucks air from the outside (puller) right through the radiator. Don't be mistaken, a front mounted fan that blows air through the rad is less efficient than a fan mounted to the back sucking air in. A huge fan infront of the rad would block air and actually make the rad hotter.

318's don't have undertrays. I removed the bulky fan shroud and clutch fan so there's a lot of room in there. That picture is really old, I added a JTD aluminum undertray a while ago. So there's an aluminum plate under there now. There's a huge space under the 325 engine too, you just can't see it because the engine is blocking your view. Just look at my SIG, I have lowering springs but my car looks like stock ride height. I guess I took out too much weight

So there is absolutely NOTHING that protects the belts and shit? WOW...

[B_w.]

how much does an electric fan like yours cost $CDN?

[Eggrolled211]

Doing this delete like so...wouldn't it mess with the crank balance of some sort? Is it worth it? pros and cons?
