When changing a thermostat, do you need RTV, or will the gasket be good enough?

Do you need to put RTV around the gasket? or will just the gasket be good enough? Thanks for any help.|||Never put rtv on a gasket,if they wanted you to rtv it would come with the gasket.|||you can put a very thin coat on it,not a bead.|||i like to use a thin layer of rtv on both sides of the gasket just to be sure no leaks.|||very little on each side of the gasket.|||Use the RTV on both sides of the gasket just to play it safe.|||rtv when wet is slippery and when you use it on a gasket the gasket can shift therefore not sealing i always use just the gasket.|||You shouldn%26#039;t really need to.Providing all traces of the old gasket are removed should be good enough.|||This is a mechanic preference, i do, some dont, it%26#039;ll work either way|||gasket is enough but u can rtv to maKE SURE IN MY CASE I NEVER USE RTV AND THE GASKET NEVER LEAKS
