1965 Chevrolet C10
1992 Chevy truck engine, 350/5.7L(v8)
I run the engine, can not see any spewing coolant, no leaks.
I park it. Check it the next day or the one after... suddenly there is coolant on top of the intake manifold, around the thermostat housing/water neck.
So, my first thought is loose hose clamp or not adjusted right on the water neck. Checked that. Gasket for the thermostat housing was replaced in November 2023... maybe it isn't snug enough?
This is making me cuckoo. Anything else I can check?
It only leaks after it sits, never while it is running... or at least not while I am looking at it while it is running.
Thanks.
