Customer Question

I have a 2001 Grand Marque LS with 100,000 mile. While driving I have had the dashboard audible alert sound go off and the radiator temperature indicator flashing. The audio alert would stop sounding and the temperature indicator stop flashing followed by the engine stalling. The check engine will go on followed by all the indicator lights as if shutting engine with the key. I had this happen several times. The temperature indicator is in the normal range, not loosing radiator fluid and water level is at full in radiator. I took the car to my local mechanic and he ran the diagnostic test and found no faults. I have had the car also just stall out on me with out any warning signals. Do you have a recommended solution for this problem?

Hello, since the check engine light is coming on and engine is stalling, a diagnostic check for codes with a scan tool needs to be done to find out what code(s) are stored. The temperature warning may be due to an issue with the cylinder head temperature sensor, stalling can be caused by vacuum leaks or an electronic sensor fault.Pulling codes needs to be done first along with a visual inspection for any damaged wiring or vacuum lines. If the check engine light is coming on then codes are stored either memory, pending or run a key on engine off and key on engine running test. Sometimes an animal can chew up wiring and cause intermittent faults.
