Changing Thermostat and using Sealer?
So im going to be changing my 1988 302 thermostat and i noticed in a few videos on youtube of people replacing it. They use some sort of sealer on the housing that they put the gasket over once they've replaced and are ready to put everything back together. They use some sort of silicone? or rtv sealer?
So before i replace my thermostat, can anyone recommend the proper sealer i should use to seal this thing right please.
