GeneralDisorder Posted June 15, 2008 Share Posted June 15, 2008 Cooling system pressure should be 13 psi. EA81's do not need an overflow tank. Remove it. The system will seek it's own level - which is usually around 1 to 2 inches from the filler neck. It should not be full - it needs room for the coolant to expand as it heats.
