Anyone use anything on their gaskets when installing a new water pump on a 194 6 cyl? Or just dry install?

good question ---- I do put a "thin coat" of 'RTV silicone on the water-pump side , then just stick (the gasket on) , install w/pump.

Even a thin coat on each side ( w/pump side & engine side) would not hurt anything either. What type "Fan Blade you run on your 194 - 6" ?

ps. -- I use either Blue or Red RTV silicone , have fun …. :D

later, jim

I use the blue felpro gaskets installed plain and dry. Surface prep is the key.

I use perma-gasket #1 on every mating surface, whether it be oil or water, been using this method since 1965.

Gasket installation info

Hi put it on dry or glue it to the pump with contact cement. I know everybody has an opinion. Do Not Use Silicone! If you do and it deteriorates it breaks loose and clogs the coolant system. The only time I had to use it with the gasket is if there is a defect in the metal warp etc... Even then it was just a thin film with my finger. A bead will squeeze out and the extra can break off and clog the system. Changed many a radiator in my day for that reason.

I have always used a very thin film of RTV but this is a subject of many opinions. None of them bad because they all work as long as nothing is applied in excess.

Bearings are a mating surface, soo......
Hell, I hope not. That's why I use oil or grease on them. The second they mate, things start to go bad.

Maybe main or rod bearing caps, but I have even heard differing opinions about a spot of sealant of choice as a thin application to a rear main bearing cap mating surface, but some people say to not to. That's the quandary I'm in now.

It depends on the maker of the gaskets, so just follow the makers instructions. The gaskets I usually use require a bit of sealant, so I use Permatex #1, been doing it that way for over 50 years, and it works for me.
