Water Pump Bolts

[Greenbomb]

I'm installing the water pump and the thermostat housing. The bolts protrude into the water jackets. What should I use to seal the bolt threads. Will plumbers Teflon tape work? I also have some white teflon thread goop. How about never-sieze? Thanks for any help.

I use anti (never) seize on all bolts going into the waterjacket and never had a problem. This includes head and manifold bolts. Others may concur or disagree but it works for me.

Actually almost anything will work, there's so little pressure. The trick here is to get the metal really clean so you're sealing metal to metal and not metal to rust or rust to old permatex, or such.

 

I've used permatex, RTV, silicone, Never-Seize, Copper Coat, teflon pipe dope, and plain old K-mart aluminum spray paint.

 

It all works fine if things are clean, and you don't put on any excess which might foul things up.

Permatex #1 or #2 .
