My check coolant error message lit up on my dashboard display, and will go of when I reset the the info button. However, when I turnthe engine off and park it for a few minutes, the check coolant light will come on again. I have had the lower engine gasket; new radiator; new surge tank; and new thermostat replaced. All these changes occured during the last year while my engine was out of the body of the car for the lower engine work. Now I have the check coolant level light coming on. Please advise.
My check coolant level error message keeps coming on. What may be the cause? on 2004 Cadillac DeVille DTS
Asked by for the 2004 Cadillac DeVille DTS
you need to check out the code first.
I took my DTS to my local Independent Cadillac Repair shop. A pressure check was done; and other diagnostic tests were conducted to rule out a head gasket or other costly repairs. The surge tank and the sensor was determined to be the problem. Repair completed; my car is now running cool and smooth.
