      My Westerbeke powered boat has a pressurized coolant tank in the port laz. The cap is a rusty mess. I read the pressure rating on it and can’t find a listing for the cap anywhere. It’s 2-3/4″ outside diameter. Can anyone share specifics of this cap so I can replace it?

      Fumble fingers typing: “I CAN’T read the pressure rating on it . . . “

      John – Thanks for the link. The pressure cap on that page is the one on the exhaust manifold, smaller size than the one on my overflow/expansion tank. I actually suspect that the tank in laz may not be original. Any way, I ended up finding a cap that I think will fit at a the POP Marine store here in Honolulu. We’ll see what happens after I get everything back together and coolant refilled.
