volvo engine heating up

brpfs · #1 07-28-2003

we have a tartan 372 with volvo engine, 1989, elsewhere, that has been nowhere for two months. Mechanics have done all the obvious, water pump, fresh water, salt water systems and everything checks out ok until load on engine and then climbs to sauna temperature down below...summer is ending....any suggestions.

I have a 1981 Pearson 323 that has a Volvo MD11C for auxillary power. The final solution to my heating problem was to take off the exhaust manifold and have it boiled
out. It apparentlly had never had it done before. I''m her second owner. I addition to that I found out that my raw water inlet ball valve was also obstructed which prevented a full flow of water to the engine.

Good Luck,

check to see if you have any air leaks in your raw water supply. You might have air going into the raw water cooling system and therefore geting airlocks. Look at crack hoses, hose clamps and specially the sea strainer gasket.
