mine leaked so bad i went though a gallon a day of coolant

I'm going threw about a quart a week. I'll mess with it in the next week or so I guess.

waterpump
 

I did a water pump on a 2001 today and found that if I removed the 3 bolts and 2 nuts (studs) on the fan mount I didn't need to take the fan and pulley apart.I just removed the oil filler tube (and plugged it to stop foreign material).After covering the rad with cardboard the whole fan assembly came straight up where the oil filler was.After the fan was out the lower shroud came out easily.
I also never removed the inner fender to remove the starter I just drove onto wheel ramps and had not trouble removing it.

Man I am so glad to have found the info you posted. I am new to the diesel world and love my GMC Duramax. I had to replace my water pump after it had started leaking on a trip from San Diego, CA back to my home in Mobile, AL. It was sure a lifesaver. Thanks a lot!

stick around, theres lots more info to be found

after helping a friend tear a duramax down to bare block and completely rebuilding it, i will never own one of these trucks, they are awesome, well built engines, but any truck that you got to remove the starter to replace the water pump is more than i want to deal with......

thanks for the write up good job helped me out a bunch :U:

In the words of Rodney Carrington "If you ever have the opertunity to do this jump off a F*&king cliff and hope theres rocks at the bottom because you dont want to live threw that shit." I'd like to find the genius who thought this out and kick him in the nuts.:argh::argh::argh:

Took me about 3.5 hours to do mine. I also noticed the surgeing issue I had is gone and found out I had a boost leak I fixed while I was at it. Nice to not come out to a puddle under the truck.

cool. nice job. 3.5 hours is pretty quick for first time (im guessing that it was ur first time) :U:

First time doing one on a Max but I turn wrenches everyday so use to busting ass working on things. Would have been quicker if I didnt have to spend an hour looking for tools again.
