I installed the coolant radiator and the coolant a couple of days ago. I have discovered the radiator has a pin hole leak in the welding join of the hose connection. I should have noticed the pin hole before I installed the radiator. KSC and I removed the radiator today and I cleaned the weld and the hole is quite obvious. I will take it to an aluminum fabricator and get it re-welded this week. A pain in the rear end, however better to find it now than later and it is a reasonably easy fix.
