It's dripping heavily and I can't figure out from where. Doesn't seem from a hose. Only leaks when engine is running. Don't see it leaking coolant around the water pump.

At Pep Boys they told me about the weep hole at the bottom of the water pump.

Any suggestions?[&o]

 

Pressureize the system to find the leak. If it is the weep hole, the pump needs to be repalced.

 

I had that test done. It was leaking from the thermostat. The gasket. I either over or unser tightened them. Hard to tell in such tight spot. Well, you live and you learn.
