its and '05 gmc with 4.8Lc, so it has the electric fans. It looks pretty simple with plenty of room.

I dont have access to my tools. Could someone please tell me what I need so I dont buy any more than I need to? tia

 

All you need a 10mm socket and a wratched and remove the 6 bolts anf hose clamps and your good to go. Good luck!

 

could it be the gaskets?

Heres how the whole thing started. Thermastat got stuck and overheated the engine. I changed the thermastat then it started leaking real bad, even though it never leaked before. I replaced the thermastat again and it still leaks. Weird.

I dont mind replacing the waterpump since it has 95k miles anyway.

 

are you sure the T Stat is properly seated in the WP?

 

I did it myself twice, then had PepBoys do it. Still leaks

 

Are you sure its laeking from the thermostat? I had a leak from the weap hole that almost took half the coolant from my engine! When you overheated the engine i could have messed up the water pump seals or even warped it. Im just thinkin here...

 

Replace the WP and go from there.

 

What he said...

 

15mm for the belt tensioner
10mm for the 6 waterpump bolts
channel locks or big pliers for the hose clamps

 

And some anti seize.
