I am trying to change the themostat in my 2003 themostat Kia Spetra. Or seal the gap. I tried to just seal it due to my boyfriend is away. But notice he said have to take out alot of parts to get to it. If cant get replace what can I use to get the sealant that is on to put fresh sealant andwhat can I use to get under the area the needs to be sealed. Water is just running out underneath.
I see you you drain the coolant remove the hose etc then unbolt the thermostat housing remove the housing clean up the housing and the engine mounting surfaces. Get a new gasket and get some permatex ultra grey silicone to seal everything up.
