"Yesterday the belt on my volv
"Yesterday the belt on my volvo 2003 broke while I was charging the batteries at about 1500 rpm. I didn't notice straight away because the buzzer is broken on the engine - I have 2 - its a catamaran.
The temp light was on when I shut down the engine, but I would guess was on for a max of 5 minutes. This is a freshwater cooled engine.
I changed the belt but am having continuing overheating problems. The coolant is blowing back out of the reserve tank. The most concerning symptom, which I only discovered late today is that no fluid is getting to the drain plug. I've done the following:
- checked the impeller (raw water is coming out the exhaust as normal)
- tested the thermostat (it opened at spec at 180 degrees)
- taken off and opened the heat exchanger - the tubes were clear
- bypassed the external hot water system
When I try running the engine, as it starts to warm up cooling water is forced back out the reservoir.
Any suggestions as to what to try next? I'm guessing this is not good new, particularly that when I add fluid, it doesn't flow out the drain plug.
Thanks,
Mark."
