Water pump?

[retorq]

The fan on the Vortec pumps don't bolts on the same, comparing them to the older setups is like comparing tuning a carb engine to a TBI engine.

trick with the new style big nut fan.

Big as crescent wrench, and 3 foot cheater pipe on its handle..
Have buddy hold it with tension on the fan nut, and you pop the pipe with a big ass dead blow hammer or sledge.
It doesn't take hulk hits, just wam it once or twice and it pops loose.

you can do it by yourself if you position the wrench and cheater pipe at a angle, and COVER your fender with cardboard and some THICK!!!! towls. or you will certainly dent it.

I have the specialty fan tools but prefer popping it loose this way, its far easier.

I just used a large wrench for the nut and clamped a pair of vice grips on the pulley behind it so it would brace on the pulley above it. Then took a small mallet and gave the wrench a decent hit and it popped right loose. Similar process as you describe ezdaar, but it doesn't sound as destructive...lol

In a nutshell, here is the process:


Disconnect negative on battery
Drain Coolant
Remove 7-8 bolts for upper fan shroud
remove fan from water pump by a process described above
remove four bolts holding the pulley on the water pump
remove belt
remove hoses from water pump
remove four bolts attaching the water pump to block
dry the area well and be sure and remove all old gasket material off block


Installation is just reverse and use some RTV for the water pump on both sides of the gasket.

Pretty sure that is about it.
I can get the torque values when I get home.

Here are the torque specs...

Fan-to-pulley nuts - 18 Ft/Lbs
Thermostat cover bolts - 20 Ft/Lbs
Water pump mounting bolts - 30 Ft/Lbs

Thanks for all the info and help. Plan on doing mine on Saturday and even better, have free access to a clutch fan removal tool. LOL I'll let everyone know how it went after the weekend. Have a great Turkey Day everyone and thanks again.

New pump, fan clutch, belt, tensioner, and idler pulley all a success. Not hard to do at all, was actually only about an hour job... jus a tick over. Best way to get that fan off... belt removal tool and an air chisel. Worked GREAT!
