2GM20F, is losing coolant
somewhere. Last Sunday I checked coolant
and topped it off in the heat exchanger
. I motored about for maybe an hour last weekend. Shut down at the dock
, cleaned up and went home! Went back to the boat
today to find the heat exchanger
empty. Put my finger in and nothing inside.
I originally thought it was the water heater
so I disconnected and by passed that and it no longer has coolant running through it! Still losing coolant.
Is it possible that the heat exchanger is leaking into the raw water
system and coolant is slowly leaking into the exhaust water
If so, how one go about identifying and confirming that leak? There doesn't seem to be any coolant leaking out the front or back of the engine! No coolant readily visible in the bilge
. I've always got a little water in the bilge
that the pump
Any suggestions on a next step?
