View Full Version : ditching the fan clutch?

09-17-2004, 12:07 AM
i took my fan cluth off today...i noticed the fan and cluch wiegh alot...maybe 10lbs. but thats rotational mass on a pulley. talk about light weight underdrive pulleys..they only shave like a lb. shaving 10 would be nice. i have an electric fan but i dont think its that good. im thinking of tryin it for awhile just leaving the fan clutch and fan off. it will clean up the engine alot to.

At first it didn't because I was always moving..
But one day I was caught in grid-lock and I noticed that it was going past the middle and it did actually over heat. :?

As long as you keep moving past 20mph and don't stay in gridlock too long it'll be "O.K" from my experience.
For you... it might be a diffrent story though... *Turbo.

i have an electric fan to

the fan clutch, fan blade, and fan blade mounting bolts together weigh 2 pounds 9 ounces. apparently you just have girlie-man arms :lol:

you need an electric fan in there in addition to the aux fan, if so equipped. grind off the fan clutch mounting nub on the water pump, this will give you about another 1/2" of clearance. it is really tight at the waterpump/waterpipe area. Be Cool, a company that makes fans, has new very thinline fans out in 16" sizes. these fans come in at just over 2" thick, and the higher powered one will pull 1630 cfm. they go for about 130 from jegs. just make sure you're looking at the right fan, they have a lot that look alike.

Maybe you can use the Aux fan?

09-17-2004, 01:03 AM
the aux fan is already there, so it is in use. it will come on not only when the ac is used, but also at 196 degrees, at 210 degrees it switches to high speed.

swartz, what's the flow rating of the fan you're using now?

it was a 1000-1200cfms i dont realy remember. i dont have an aux fan, i dont have ac or ps either

you're gonna want more than that, especially without the aux fan. you will run into issues

I just removed it, and installed a double speed one form a E36 on front of the radiator, with a swtich of 80-88 C (176-190 F) Do you think it will be OK? Haven't got the chance to try...
