Thermostat DIY

I agree with the RTV idea. I installed a new thermostat when I did a cooling system rebuild, torqued the thermostat to 10NM, etc., and it weeped slightly. I re-drained the radiator at the right side lower plug, removed the shroud and fan, disconnected the upper and lower hoses from the thermostat, RTV'd the mating surface exactly like in the photo here, and no more leaks....
