Right, quick explain, had a diesel heater fitted which went a bit wrong! Have a Mitsubishi marinised 3 cylinder engine, which had an air lock due to not bleeding keel cooler. Noticed a weep under fuel pump, so decided to change seals as the originals were not in good health. I now have a coolant leak out of the weep hole on the water pump, and am losing a lot of coolant. Is it just a sign that the gasket in the water pump is not sealing or is it something more serious?
I've gone around the houses the last week, so could do with some advice!
Thank you.
