So I have ranted on here about my overheating problem on my 86 Bayliner / Volvo penta aq125, VP 270 outdrive. After alot of suggestions I aquired a seloc manual and started in on the problem one possibility at a time. I took off the heat exchanger and really saw nothing in it, cleaned some debri and (obviosly)drained the coolant ( I believe it was 100%, putting 50/50 in). Well I then reattached the heat exchanger to the block and the coolant reservior, and pour in the coolant. It poured right out of the connections. That is frustrating, I cannot get a good seal!! Is there some trick? I was careful to put the o-rings back into both of the joints and it still leaks!! What is the best way to stop this leaking, to seal the system?? Thanks!
