327F heat exchanger pressure cap

Post by Jeff Weymouth » Sat Aug 20, 2016 3:38 pm

Does anyone know the correct heat exchanger pressure cap value? I'm currently running a 5 PSI cap. I had a heat exchanger tube fail and the seawater pump had enough pressure to fill the fresh water side with seawater and overcome the "radiator" cap and pee out the overflow tube into the bilge.
