Thermostat Gasket Q

[mrhp]

Do I need to use sealant with the Fel-Pro 35063 blue t-stat gasket? Thanks

I use it. Skim coat. Just enough to coat it & to hold it.

I do as well. I also use some non hardening sealant on the bolt threads.

I use an “o” ring thermostat housing, problem solved.

You can use sealant on the "blue stripe" Felpro gaskets. Do not use sealant if it is a Felpro "perma dry plus" gaskets. You are safe, the 35063 is just the "blue stripe" design. Check out www.felpro.com
