trying to change the water pump on my moms '00 exursion... had her pick up the pump and a set of wrenches from advanced I think.. but for the life of me I can't get the fan off.. the life time gurantee wrenches are already bent and I can't get the freakin thing to budge.. the wrenches are about worthless.. any other way/ways I might be able to get this thing off? it's holding the pulley that I'm having trouble with.. and after putting in 42 hours already my fuse is pretty short. and I've got to have this thing done tonight and be back to work at 4.. :0( sorry for the rant but thanks for any help!

 

Found below paragraph from this link.Diesel-Central.com the technical source for Diesel Truck information, Truck Pulling, and Drag Racing

Remove the fan and fan clutch from the water pump pulley. The large clutch assembly has a right-hand thread and must be turned counter-clockwise to remove. Hold on to the belt pulley with the strap wrench, and use a 1-7/8 inch open end wrench to break the fan free. When removed from the pulley, carefully lay the fan down into the shroud temporarily.

 

Its reverse thread... I assume you know that. Other then that, I used a grip wrench when I did my wifes Excursion.

 

thanks a ton.. even though it looks she won't be making her trip on time I'm pretty sure I know how to get it off now..

 

it's standard right hand thread,left to loose-right to tight
I found it easier to remove the radiator to have more room

 

well, what is it? standard or not? I was turning to the right.. but then most everybody I have talked to told me to do that..

 

it is standard thread turn it the same as any other bolt

 

I had to use an air chisel to get mine off.

 

Tim,

I just went through this myself. My local diesel mechanic told me it was reverse thread, my manual told me it was a "right handed", normal thread.

The book is right, it is a right handed thread. Turn it counter clockwise to loosen it. I found that if I left the belt on (I was replacing it anyway) and put a long wrench on the fan nut, it took a couple of good whacks with a 2 lb hammer to break free. The belt provided enough resistance to get it loose (I didn't have a strap wrench big enough for the pulley). When you do it don't be shy about hitting the wrench, you'll be there all day - ask me how I know..

Once it broke free I was able to spin it off by hand. Be careful and don't damage your radiator when you get the whole assembly loose, it's a little heavy. I used a little copper anti-seize on the threads when I put it back on, for the next time..

Good luck.
John

 

Thanks John,

I will add this to my tech file , Reps sent.

 

Like "black jeep" states, worked for me. Strap wrench the pulley real tight (or try with the belt on), maybe get a friend to hold the strap wrench or prop it against something. Put the 1-7/8 inch open end/box wrench on the bolt and pull real hard then smack your open end/box wrench with a hammer. Put a shock to it like an impact wrench would do. Might snap it loose. (your probably going to need a good strap wrench to do this if it is that tight)

Here is the documents(complete section) off of the repair manual.

Here is the link of the manual from an 01 i got them from https://www.motorcraftservice.com/pu...20/S1OMAIN.HTM

 

Take A Pair Of Small Vice Grips And Clamp Down Really Hard On The Outer Lip Of The Water Pump Pulley . . . . Brace The Handle Of The Vice Grips Against The Idler Pulley To The Left . . . Or From The Bottom . . Brace The Handle Of The Vice Grips To The Right Where The Fluid Goes To The Radiator On The Bottom.
