I have had a coolant leak around my thermostat housing many times now. the last time I fixed it i put hi-temp gasket maker around the housing but it is still leaking somehow, any suggestions

What year/engine ?

If the gaksets not set with in the recessed area on the intake, it could leak out the bottom. Or your thermostat housing is cracked!

Could also be the hose leaking, is it on all the way ?
