Question E-fan Intsall problems... need help with clutch fan removal

hey, I have a 2001 4.3L. I was trying to take the clutch fan off and had some difficulties with it... Can someone make it easy for me by giving me tips/instructions on how i should go about this? Is the bolt coming out of the pulley a reverse thread or what? and how is the best way to keep the motor from turning over when im trying to take that bolt off? Thanks a lot for your help... ill check back after work on monday and hopfully ill have some replies.

Re: E-fan Intsall problems... need help with clutch fan removal

i dont know about the new ones but on the old s10's all you had to do was take the four nuts that held the whole cluth assembly to the water pump then put the nuts back on. i cant remember if the new ones are like that or not...

Re: E-fan Intsall problems... need help with clutch fan removal

there should be a clutch fan wrench kit you can borrow from auto zone... it has one wrench that holds the water pump pulley, and another for the clutch fan nut... it is a normally threaded nut so righty tighty lefty loosey. if you have trouble take a mallet, hold the water pump pulley and smack the wrench on the clutch fan nut. I just put a new E'fan in today so i did exactly that

Re: E-fan Intsall problems... need help with clutch fan removal

ohh also try and position the wrenches so that you can squeeze them together with one hand, that will get you your best leverage.

BadaSS_Black97, thank you for the advice be keep checking back if you would, i might try and do it tonight if i have time but who knows. Ill probably go to autozone after i try the mallet. Oh and, thanks for telling me the thread pattern, i was really getting pissy last night trying to turn it both ways haha.

Re: E-fan Intsall problems... need help with clutch fan removal

wow, you people like to make it difficult...

just take a cresent wrench a big flat-head screwdriver and a hammer... adjust the cresent wrench accordingly, wedge the screwdriver between 2 of the bolts on one side so it won't spin and hit the wrench with the hammer... takes longer to take off the fan shroud

Re: E-fan Intsall problems... need help with clutch fan removal

BlackESDime is right -- on the newer ones, it just takes a large cresent wrench and a large screwdriver to wedge between 2 of the 4 pulley bolts to hold it still. It'll break free. Normal threads. Or, drop the belt and put a strap wrench on the pulley to hold it while you break the fan nut free. Did that on a buddy's recently.

Re: E-fan Intsall problems... need help with clutch fan removal



Get a wrench that fits on the nut, put a screwdriver between 2 of the small nuts, and smack the wrench a couple times. It will come off easily... I originally used chain vice grips but any wrench you can fit in there will work. Its the normal left to loosen right to tighten but its backwards from you so you want to smack it to the right if you are at the front of the truck.

One of the more useful tools, in my opinion. Can get like 3 of 'em for <$20 at Sears, lifetime warranty... can't beat that

Re: E-fan Intsall problems... need help with clutch fan removal

Well guys... i went to Sears and baught a 2.5" cresant wrench and a set of strap wrenches... came out to be like 48 bux after tax.. . I worked on it last night because i finally got the time. I put the strap wrench on and the cresant, had the strap wrench rest on the AC pulley, and smacked the cresant with a hammer... (TO THE LEFT FROM THE FRONT... NOT THE RIGHT). The nut came lose and away i went... it took me and a friend that had some experience from his 87(?) S-10, where he has a 350 in it, put some fans in himself. It took us about 3 hours after all was said an done... just because of the wirering (which i hate now) but it was a pretty clean install if i do say so myself. I only spent ~ 5 dollars to do this efan... hehe. My friend had the fans and the wires i just had to buy the conectors. I think im gonna get a 160 deg thermo next. Thanks for everyones help, and the best way is to use a 2.5" cresant, Strap wrench, and a hammer.

what magical nut are you guys talking about?!? You guys need to explain in better detail, that's way to vague. Where do I put the screwdriver? I've been trying to remove the fan clutch for over an hour! Help fast!

Re: E-fan Intsall problems... need help with clutch fan removal

the problem is not a matter of strength or force it's a matter of trying to loosen the right focking things. a screwdriver does NOT fit in between the bolts on the water pump pulley. it does not take a few 'taps' to loosen, can someone give me a real explanation, this is a joke.

Re: E-fan Intsall problems... need help with clutch fan removal

get a strap wrench from sears... put that wrench around the pulley. Use a cresant wrench and put it around the nut/shaft that goes to the fan itself... hit the cresant with a hammer and its home... it may be differant on yours... mine is a 2001 so there could be some differances.

Re: E-fan Intsall problems... need help with clutch fan removal

I can barely fit a big enough stap wrench in there and it's spinning in the strap. It cannot be this difficult. can someone please walk me through this with DETAILED instructions, not using the speciality tool becuase all the parts stores in my area are out.

Re: E-fan Intsall problems... need help with clutch fan removal

This was a total pain in my ass too. Until I found that Kragen sells a kit (three hours later) to take the fan off. With the kit, it only took like 2 minutes.

Re: E-fan Intsall problems... need help with clutch fan removal

Howdy,
I'm new to the group and loving what I've read and the hints I've gotten so far. I just did it last night with the autozone removal tool. If you bought your fan clutch at Autozone the first thing you need to do is take it back and go to NAPA or O'reillys. Borrowing their tools are fine, but never buy parts from them. I bought a belt tensioner and belt from them. The belt tensioner failed in less than a day, and the goodyear gatorback belt they will sell you is the wrong one(go to the autozone website and lookup the goodyear belt they say is for our trucks(4060952), then go to the goodyear site and lookup the same(4060950), the belt they sold me squeaked like a mother until I realized it is 5/8" too long). You take the wrench with the bigger openeing, and put it on the bolts on the water pump, these are the four that kinda surround the big nut that holds the fan on. I think you want to put this wrench on the right side to get the best grip. then put the wrench with the smaller opening on the big nut that attaches the fan to the water pump. Standing in front of the vehicle, you want to turn it to the left to loosen this nut, my truck is a '99 with the 4.3 and the fan nut is NOT reverse threaded-lefty loosey, righty tighty. Just be patient and it will come. As for the fan shroud, I was able to just take out the bolts on top and the two to the left, this loosened it up enough for me to sneak the fan out. When put it back on, the haynes manual says the torgue spec is only like 14 or 17 footlbs. I had no way to measure this, so is just got the bolt "snug" and then a little. Drove all day today and it worked fine.
Good Luck,
Shawn

Yep, its threaded normally. Lefty Loosey. Oh, and when you're unthreading it the rest of the way... hold onto it. Don't let it crash down by the crank pulley and possibly thunk up your radiator

Re: E-fan Intsall problems... need help with clutch fan removal

Reverse thread would be left to tighten, right to loosen. Standard thread would be left to loosen, right to tighten.

I was thinking at the time that the nut was facing the opposite direction. Sorry.

It is left to loosen if you are standing infront of the truck..

Re: E-fan Intsall problems... need help with clutch fan removal

no, because it's not installed. my water pump went out and I had to replace it today. But I got the fan clutch off. SO i'll install it soon and get some pics up. You guys were right. It's left to loosen when you're facing the truck.
