Getting hot out here. Truck is running without overheating or boiling over. Hits about 220 in traffic. I popped the hood and noticed dried coolant around the housing bracket and some spray on the valve cover. Realized that my radiator cap is 20 pounds? Is this likely the issue? I changed it last night to a 13 lb. T-stat is the 190 from WH.
Motor details in my sig. The T-stat is new but sat for a few years before motor was first started. I also have a 5 blade fan. Radiator I assume is the stock 1969 for a V8 but it does look thin.
