how did u fellas get the mech fan off of the water pump pulley without the pulley itself turning? i been tryin to turn it for a while and even with my gatorback belt it slips a lil. im dying to get this thing off so i can throw my elec fan on.

 

Autozone will loan you the tool to remove. Turn in the direction of rotation. On my 99 4.2 it was left.

 

yeah they gave me a tool for removing clutch fan but im gonna have to tak it back, smallest wrench was 40mm and thats still a lil too big. problem im having is how the heck to hold the water pump pulley snout still, while i turn the fan to loosen it. it wants to turn the pump pulley with the fan getting me no where

 

the one you need from autozone is for the older 4.9L and 5.0 V8, same fan size and waterpump size....

 

ok cool anyone got an idea on how to hold the water pump from turning? seems like when i turn the fan to loosen it it turns the pump, im assuming standard threads on that thing ( righty tighty, lefty loosey).

 

there is a huge wrench, shaped like a boxy U that you put over the four bolts on the W/P, and put a breaker bar onto the wrench for added leverage

 

hmm ok then im assuming u use a crescent wrench on the actual fan after u place the boxy u wrench to hold the water pump?

 

alright got the boxy u wrench, it seems to hold the water pump it came with a 54mm boxy u wrench to hold the water pump, anyone have any idea what size the fan actually is? it came with a 40mm wrench but its to large a bit for the fan. what do u fellas recomend to use on the actual fan? is it a 36mm? did u just use a adjustable wrench? i got this thing licked if i can take the fan off.. thanks for the info on the boxy u wrench patman, turns out i had my head in my **** and didnt even think the tool i had was to hold the water pump. i was just using it to turn the fan off the water pump.. thanks alot again, man i feel like a real rocket scientist..

 

man this things on there tighter than i thought it would be.

 

still having a heck of a time im alsmost to the point of paying to have the fan took off. shoot i can do the rest.... wish i woulda put this on when i installed underdrive pulleys, wishing now i wouldnt have put the fan back on with that air chisel attachment.. though it was quick id love to have an air compressor and air chisel again.

 

Mine required a 1-7/16 or 1-3/8 open end wrench. I can't remember which end of the combo it was - I think the 1-7/16 though.
It should not take more than a good bump to break the fan loose. If you can get someone to hold the wrench on the pully, just bump the wrench on the fan with a short handle sledge hammer - just make sure you are turning the correct direction.

 

standard threads correct?

 

It is threaded backwards. YOu may be trying to tighten it.

 

you gotta b kidding me? i been crankin on that sob all day and i been turning it the wrong way?? son of a i just came back from returning the tool to autozone, i feel like a real genius. i had the fan install licked if i coulda got the old manual fan off! guess i learned the hard way.

 

at the point now where id just pay to have someone put the fan on for me.
