Yesterday I changed out the HX on my 94 Mercruiser 5.7 FWC motor (alpha drive). I filled the exchange with fresh 50/50 antifreeze. My question is when I restart the engine, should (can) I start it with the radiator cap off to allow any air to escape?
Also when my mechanic did the other engine for me last year, I remember him opening a bleeder valve on top of the thermostat housing cover. I think he did that when the engine was running and the cap was on the heat exchange.
thank in advance.
