Hi, my son has a 98 JGC, 4 cylinder 2 wheel drive, SUV. His car overheated so I replaced the water pump, refilled the fluids and started it up. Once operating temperture was passed, it began to overheat again and the water pump started to chirp.
Thinking I could have gotten a bad pump, I bought a 2nd. As well as a new thermostat.
As I removed the water pump I noticed that there seemed to be no water within the engine block or lower radiator hose attached to the bottom of the water pump.
I installed the 2nd. New water pump and thermostat,
added water and antifreeze, cranked it up and let it run. After a few minutes the engine began to run hot again.
I happened to touch the radiator cap and noticed that it wasn't hot. I removed the cap and the water within was not hot nor under any pressure.
Do you have to "bleed" the circulation system? Could it be a control valve of some sort. Could the rediator have clogged it self up so compleately? Help!
I have donated.
have the same problem?
