Question Asked: engine overheating
August 28, 2010, 11:21 AM
my "low engine coolant" light comes on and the coolant overflow tank reads normal. I checked (by jumper wire) both cooling fans, and both work. I replaced the thermostat (installed with spring inside engine, I replaced the water pump, and the radiator was replaced 1 year ago. the car heats up, and the top radiator hose gets hot, and eventually presurizes so it can't be squeezed by hand, then the water temp guage climbs steadily into the high overheat range. I shut the car off before it gets to the "red" mark. There are no coolant leaks. Is there anything else I can check?
