Gasket material

[lar]

I'm replacing the entire cooling system in my 76' FJ40. What is the best direction to go back with in reference to the gaskets for the water pump and thermostat housing; paper gaskets or RTV type gasket material? Mine had a combination of both in some areas and just the paper type in others.
Thanks-
Kevin

Personally I like a combination of both - paper with a very thin layer of Toyota FIPG sealer on both sides. About as thin as I can spread it with a finger. My sh!t doesn't leak.

Don't forget the rubber donut in the top of the thermostat housing (which needs no FIPG).

Both for me. No leaks......so far.

I have used Permatex Aviation Gasket sealer with the paper gaskets with good results on the previous three 40's and am using it on the current'77. Also use on aircraft. I assume it is similar to Toyota FIPG. Correct me if I am in error.

I always use the stock paper gaskets in conjunction with Permatex Hi Tack sealant.
