Both mating surfaces gotta be sterile clean and use RTV sealer on both sides of the gasket. DO NOT OVERTIGHTEN, just snug.

Stands for Room Temperature Vulcanizing......would think it would be available everywhere. And like Mott said, make sure the t-stat didn't slip out of it's recess.

Would a cracked timing cover cause a coolant leak?
