"Fan delete mod"

[7pilot]

so the M20/M50 thermostats are the same size? so i could put the 75* from my M20 into the M50?

I would buy a new one for peace of mind.
These engines run hot as normal, so the safety margin for the head gasket is lower, than for the older engines.

why would you want the fan to work independently of the air conditioning? the factory designed it that way for a reason. if you delete a/c then the fan would only come on when the engine is hot anyway. why not just use the factory wire that runs to the stock fan? if you have a single speed fan, you can hook to the low speed wire and the ground. since the wires are already heavy guage, switch from a 15 to a 30 amp fuse(or whatever the fan manufacturer recommends) bam! all done! what am i missing here?

If you want to add a puller fan that won't kick on with the AC, try this...

So I hooked up this way using the blk/brn wire and the fan never came one. I used the test light and when I touched the blk/brn on the relay the fan went on. I am guessing I need the new rad switch?? Or is that wire only work when a/c is on? Just thought of that.
Thanks

Yes... but you should be running an 80C instead.

i just took the fan off and left it off when i did a thermostat replacment on my m42. stays cool easily, have no worries driving in any traffic.

it actually doesn't matter what motor you have, the premise is the same as are the actual modifcations required.

Yeah I was thinking it could be done to any, and if there are even any gains

Seeing as it's in the 24V DOHC Swaps section, I'd imagine it's for a 24V motor.

Yah sorry my noobiiiness
I just clicked it in the Main menu forum thingy

So after all this discussion is this mod worth it for a street e30 M20 ?
Is there any power gains?

Edit:
Sorry if I am confused, but is this even for the M20 or 24V?

Thanks for the quick responses btw. That makes sense about the t-stat. I am thinking to replace the stock fan with an upgraded one. I do want the system to work optimally so i dont mind using another fan.
