Today I decided to replace the thermostat gasket because of a small leak from it. Drained the coolant, proceeded to remove the housing. I cleaned the intake surface and the backside of the housing because of some pitting. Then I installed a new gasket and used a sealant. Got everything back together and started it up. Leaked more now than before, so I tightened it up a bit ,that made no difference, still leaked.
Should I use a sealant or not? I ordered a new gasket and a new housing because of the pitting. If I use a sealant, what should I use, the blue silicone or what. I do not remember ever using a sealant, just the gasket.
Thanks
