1997 gmc jimmy water pump removal

4.3, 4x4, automatic, 115,000
I noticed the weep hole was leaking. So I started to tear it apart. The fan clutch assembly seems to thread on to the shaft of the pump. I have tried to break lose with out any luck. Are these right handed threads? What is the best way to hold the pump pulley in place while trying to break loose. I broke 1 of the bolts off try to hold with a wrench wedged agains the belt tensioner. There are extra holes in the pulley (maybe for a special tool). I stuck a bolt through one of these holes and locked down with 2 nuts and it just bent over when I tried to break it loose. Any ideas?

Thanks for any input

Go to your local autoparts store(Autozone, Advance,etc.) and get a manual for your jummy (Haynes, Chilton about $12.00) then you can fix anything else that goes wrong also. The Haynes manual is no. 24071. The removal is a detailed process and I would be typing all nite. Have a nice day. Geo

I got it. I used a pipewrench with some cardboard to hold the pulley so I could break it loose. Thanks.

I have the manual I listed and it gives instruction in detail it is a Haynes 24071 which covers S-10 & Sonoma 94-01, Blaser & Jimmy 95-01 and Olds Bravada & Isuzu Hombre 96-01. The article is detailed in chapter 3-3 thru 3-6. The ISBN is 1 56392 447 1 the bar code reads 38345 24071. Have a nice day. Geo

they do make special tools to help remove those style fan clutches it can be hard to remove them without it but possible.
dont really think a manual is going to be much help in changing out a waterpump.
