1984 Lesharo 3.8L boiling out after idling for awhile. I started up the engine and the generator for a monthly exercise. Apparently, while sitting still, this rig can overheat to some extent. It never did overheat, but I think an airspace inside of the lines below the really high-up heater core caused boiling and then overpressure. The engine gauge never overheated itself. So while it sits, the high-up heater core fills with air.
