Hey guys,

I have a major leak due to my water pump gasket. The truck is bone stock and don't think the original owner had replaced anything. So instead of just replacing the water pump gasket, I'm going to replace the entire water pump. I've never done this and was wondering if you guys had any pics and/or special instructions on the easiest way to do this. Thanks in advance!

 

no pictures but its pretty much straight forward. take off the fan shroud and clutch fan. Then unbolt the waterpump. Make sure the old gaskets come off of the block. Bolt new waterpump on. Thread the fan back on. Fill the coolant back up to proper level. After youre sure everything is fine, put the shroud back on.

 

Sweet! Hopefully it goes that smooth...

 

Yeah I did a friend's truck in a little over an hour. You might as well pick up new bolts at the dealer if you're going for a new pump. My friend's leak started as a slow drip and it had corroded two of the bolts pretty bad.

 

EDIT

Why talk about it. Let's DO IT!

Reference photos. Left and right side bolts for removal of the water pump.
Remember to take your heater hoses off the side.
Clean the surfaces of the block and water pump, then lay your gaskets on the pump. Lay the pump on its side, and slide your bolts through the mounting holes to hold the gasket in place.
Carefully lift up the pump, bolts, and new gasket and place up towards the block. Carefully thread in a few bolts and then slide the pump up towards the block and snug down the bolts by hand.

Ok, am I an idiot or is it really not that hard to get the fan off? I've got almost everything off and I can't for the life of me get that detached from the water pump. Can anybody explain?

 

Ive had to get a decent size hammer and put your wrench on the fan nut and hit the wrench one good time and it spins right off...

 

or, the whole assembly just spins.... the belt might not hold enough tension on the pulley. since yours is a 99.. it might be on there pretty good. as it was on my 99. i couldnt even get a strap wrench to work. im sure if i had a proper one it would have.but anyway, since you`re replacing the pump, damaging the pulley wont be an issue. i just ended up clamping some vise grips on the pulley, it wedged itself against the pump, and i was finally able to break it loose.it could come off easily, but it can be a bitch as well.

 

I'm trying this, and it's still a bitch to get off. The f'n thing is not budging. I tried heating it up for a couple minutes, but to no avail. I guess I'll keep plugging away at it. This sucks!!

 

well, did you get that thing off yet... or what?
