hi there,,i am going to fit a new thermostat housing kit on a KA 53 plate with the duratec engine

is it wise to use any gasket seal blue gasket for example when mating the two surfaces together

there is a new rubber gasket that came with the housing

i have removed the old housing and gasket because it was seeping abit and was thinking to use blue gasket to help seal it up ???

many thanks,,,

if the mating surfaces are clean and flat just the gasket should be fine

just the gasket no sealant & dont over tighten the bolts that hold it all in place

ok many thanks,,,
