I have a 2001 Chrysler Sebring LXi 4dr Sedan (2.7L 6cyl 4A). It is overheating. The thermostat has been changed, the hoses are not clogged or leaking, radiator cap is in good condition, no noise coming from the water pump, no water in the oil, But when we try to add water/coolant, the enging wont take it. It wont suck the water in through the motor. The water is blowing out all over my drive way and is overheating.
If ur engine is running & thermostat is open & close there is pressure in the system. Of course it won't take any more coolant.
Water pump can deliver less than its capable circulation volume still make no noise.
Try a professional qualify shop. Overheating is not big deal for a skill level mechanic to nail it down.
