Ford Lehman 135's. The heat exchangers, oil and tranny coolers were taken off, pressure tested, and "serviced" by the previous owner in 2013 prior to cruising. He paid to have the work done, didn't do it himself. They were given a clean bill of health, repainted in that nice Ford Lehman red and put back on.
OK. Now I own the boat. Have no idea how old the HE/coolers are. opened up the HE when I flushed the system w/Barnacle Buster and they looked fine to me. the exteriors look brand new (PO was a meticulous engine room guy) Of course that was the first HE I ever looked at so take that comment with a grain of sand.
I believe the worst thing to happen ion the group is the tranny cooler going kaput and allowing water into the trannys. Rebuild time. Now call me crazy but I would rather stay away from that.
My question is...when do you replace these? Wait for something to happen or is it a wise decision to say "That's long enough and I will just feel better with new ones"? Any rule of thumb on these?
