I've got a leak which is in the area of the upper hose/passenger side of the rad. Only happens after the engine is shut off, leaks nothing when running. Seams on the rad look good. Hard to tell exactly where its coming from as the whole battery tray area is damp. I'm thinking the upper hose is leaking somehow and it's trickling down to the battery tray to the ground? Anyone have experience with this?

I'm borrowing a pressure tester tonight and will post results.

Check clamp for tightness. If hose is OK, it's probably the water inlet fitting that is cracked.

I'll take the hose off after work and look into this. If the inlet fitting isn't cracked, would you recommend a new hose/clamp?

Most likely. Also look at the joint where the tanks are crimped on to the cross tubes. Mine was leaking there and sprayed to the battery tray, only when cooling down....Was a lovely mess it made.
