I replaced the head gasket about six weeks ago. It started perfectly and ran well.
I've towed my trailer with it a couple of times with no issues.
Today I went to the sawmill and towed home a load which was probably 2.5 tonnes. About a mile from home which is on top of a hill, I noticed the temperature gauge was in the red, and that the heater was blowing cold air, I made it home just as the oil pressure warning light came on.
The expansion tank was under pressure and coolant was splashed inside the engine bay, possibly by the fan. I couldnt see an obvious leak or disconnected hose. The engine struggled to turn when hot, but would happily restart when cold. I checked the radiator, it took about a litre of water to refil it, and I checked the thermostat housing, and it was empty, about a litre filled that too.
When I restarted it there was no pressure in the expansion tank. There are no signs of oil in the water or water in the oil.
So what is going on?
Can you suggest a check list to find the source of the problem.
