    Water pump replacement. Help!!!!!

    I'm ready to replace the water pump in my dads truck. The motor is a 4.8 v8. Will the gaskets need silicone? Any tip's or a link where it takes you thru the steps.

    No, the gaskets already have an oring type elastomer material like (neoprene, Fluoroelastomer - Viton® & Fluorel®, Silicone, Buna 'N' (Nitrile). on them so just make sure the surfaces are clean and you'll be fine. You can put silicone on them but it makes a cam or timing chain swap harder.
