I need help with an overheating problem
I put a 1.6, 16v motor in my Sami in August. It ran great until last month. I was 4 wheeling and it got close to the red zone, but not in it, and ever since then, it has become progressively worse.
After about 10 minutes of driving, it gets hot enough to put the needle in the red. I can hear the water boiling in the engine/radiator hoses and it pushes water and steam into the overflow bottle.
So far, I replaced the head gasket, radiator cap, thermostat, fan and clutch. I removed the water pump and the blades are turning when I spin the other side. I ran the engine with the cap off, and I can see the water pump is pushing water. It pushes it fast enough to pump out the open cap when I rev the motor. The fan is definately turning when the engine is running. I don't see any water in the oil, there is fresh oil in the engine.
I am totally at a loss. It was running fine for 2 months, then starting running hotter and hotter. [img]images/graemlins/confused.gif[/img]
