On Sketcher, our 1983 35' Ericson we have two radiator caps.
One on the engine 3-cylinder Universal and one on the overflow tank that services the heat exchanger for hot water tank.

Does any one know what pressure these caps should be?

I think Westerbeke is a 15 psi cap for the engine. Not sure regarding the heat exchanger.

Our manual for our 5416 16 hp universal diesel says it should be 7psi, but we've had 13psi in both for the past 12 years and not had any problems.

Our '88 model Universal M25XP had a pressure cap on the engine coolant fitting, but the overflow tank was ventilated to atmosphere.

And our new Beta 25 uses the same coolant plumbing system.
