Re: Coolant puzzle
I found another tank right next to the hot water heater with a pressure cap and an overflow hose.
I may be reading that wrong, but normally the pressure cap would NOT be on the expansion tank, but on the engine or water heater tank. The higher one I would think. Expansion tanks usually have just a silly splash prevention cap.
