OK, I replaced water pump and therm housing and now on occasion while just sitting there for days without running I come out and there is a spot of antifreeze from 1-2" in diameter probably just a few drops. Might sound crazy but do these things burp from somewhere or my guess is the pump needs to be redone?

 

Unless your overflow is full to the brim.... no yhey should not drip at all.

 

Crack or break anything during the install?

 

Don't think I broke anything, think I will redo the pump and use RTV this time.

 

I would suspect that one of the hoses are not tight. Usually have to check them after you run it again.

 

Dont pull the new pump till you see the source of the leak.
Sometimes the older hoses get squeezed and cut by the hose clamps.
Wasn't perhaps some residual coolant that was laying on the rad support or some coolant mixed up with some snow and then melting and dripping?

 

Live in the desert so no snow here unfortunately. Looked tonight and can see runs behind the harmonic balancer to the oil pan bolt. So I think I need to at least loosen the belt and remove the pulley for a closer look.
