Seized fan clutch!

[DiecellDan]

Ok y'all. I've tried everything. Ive tried the tool set from AutoZone, tried an air hammer, my pops, father in law, buddy of mine and my brother have all tried their own methods. The damn thing is stuck. Any ideas? I'm trying to replace water pump. And fan clutch lol. We gave it from 8am to 8pm yesterday. And yes, we're turning away from driver side

So... you state your turning the wrench towards the passenger side of the truck ...Thats the wrong direction. The fan clutch nut thread is a left hand thread. So its turn it the direction to tighten a usual thread.Simple rule is righty tighty and lefty loosey. With a left hand thread this rule is backwards. BTW the fan nut thread direction is cast into the fan shroud.

U say you used air hammer....chisel or pnumatic wrench set

Why is it coming off

 

[DiecellDan]

@icanfixall you said the fan clutch is a left handed thread and needed to follow the lefty loose rules. Then you said a left handed thread should be backwards?

 

[Macrobb]

No, he said that the normal rule is lefty loosey, rightey tightey. A left hand thread is opposite that. You want to do lefty-tightey, rigtey-loosey.

 

[DiecellDan]

Ok so, I should be turning right? Towards driver side?

 

[Thewespaul]

yep

 

[Macrobb]

If you are at the front of the truck looking back at the cab, you want to turn the clutch nut clockwise - top towards the driver's side, bottom towards the passenger's side(if that makes any sense).

Dude when I rebuilt mine I couldn't get it off either. Literally just left the fan attached to the water pump and pulled the whole thing. Worst case scenario, these fans would lock while engaged so your only problem would be fan operation during highway speeds causing over cooing

If your replacing the clutch and water pump just cut the clutch off at the nut and pull the fan out with the other part of the clutch still attached.

It's easier too, if you leave the belt on. That way it helps hold the water pump pulley while you try loosen the fan clutch.

I recently replaced the fan clutches on both my IDI and PSD. On both of them they were tight enough that I used an air chisel.

In any case they probably need some impact. If they are not too tight using a long wrench and smacking the end with a mallet can work.

It’s left hand thread. This is the tool you need.

Totally worth the money. If it was red loctited on, a little heat on the nut first would be a reasonable thing.

Oh you must mean the ones that give off an annoying buzz. I HATE those things. A good, long barrel air hammer is the ONLY way to go.
