2004 Chrysler Sebring Q&A
2004 Chrysler Sebring Question: cooling system
coolant in recovery tank boiling. replaced thermostat, drained all air. replaced with new radiator. ran gas test, neg for cracked head or blown head gasket. temp gauge at less than half and bottom radiator hose is cool when the recovery tank is boilng over. is water pump next on the agenda. - vietnam
Check your radiator's flow capacity to insure that the radiators tubes are not plugged up. Test your Coolant Pressure Cap. Pressure cap not installed tightly. If cap is loose, boiling point of coolant will be lowered. Verify proper pressure cap part number. Check condition of pressure cap and seals. Other methods to check for combustion leaks are; Possible indications of the cylinder head gasket leaking between a cylinder and an adjacent water jacket are: CYLINDER-TO-CYLINDER LEAKAGE TEST To determine if an engine cylinder head gasket is leaking between adjacent cylinders, follow the procedures in Cylinder Compression Pressure Test. . An engine cylinder head gasket leaking between adjacent cylinders will result in approximately a 50–70% reduction in compression pressure. CYLINDER-TO-WATER JACKET LEAKAGE TEST WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING WITH COOLANT PRESSURE CAP REMOVED. VISUAL TEST METHOD; With the engine cool, remove the coolant pressure cap. Start the engine and allow it to warm up until thermostat opens. If a large combustion/compression pressure leak exists, bubbles will be visible in the coolant. COOLING SYSTEM TESTER METHOD; WARNING: WITH COOLING SYSTEM TESTER IN PLACE, PRESSURE WILL BUILD UP FAST. EXCESSIVE PRESSURE BUILT UP, BY CONTINUOUS ENGINE OPERATION, MUST BE RELEASED TO A SAFE PRESSURE POINT. NEVER PERMIT PRESSURE TO EXCEED 138 kPa (20 psi). Install Cooling System Tester 7700 or equivalent to pressure cap neck. Start the engine and observe the tester's pressure gauge. If gauge pulsates with every power stroke of a cylinder a combustion pressure leak is evident. - Johnny Mopar
The coolant in the recovery tank is boiling and steaming. I replaced the thermostat, drained all the air out of the system. replaced radiator. still have the problem, whats next.
so my last post, Question: where can I find someone to replace my thermostat? now today i went to a shop to have them put in a new thermostat. $180.00 last week i went there and they did a full com...
Just replaced water pump, timing belts, thermostat, sparkplugs, heater core hoses. Did a cooling system flush and still the car runs a little hot. Also, no heat works in the car at all. Could the tr...
There is coolant spray on the engine centered at the thermostat/temp sensor area. Seems to be coming from below that point. No visible hose leaks. Water in the overflow tank is cool. Some coolant l...
Is it normal for a water pump to go out at 70000 miles? Also after coolent was put in because it was very low the car stopped leaking and also getting to hot. Is this normal?
