I have a Universal 5411 (M-15) in my 1983 Ericson E28+ with the factory modification for fresh water cooling. Also there is the original Raritan 6 gallon water heater in the mix. The (vertical) heat exchanger has a radiator cap on it. The Raritan has a square metal tank as part of the circuit with a radiator cap on it also. Both of these are connected to the same coolant recovery tank. Can anyone with an arrangement like this please tell me what size (PSI) radiator caps you are using? Thanks.

The PSI of the cap will be based on the engine, regardless of what type of water heater you have. Check the psi on www.marinedieseldirect.com
