have a 98 buick regal gs sedan. the "add coolant" light is on, the car is NOT heating up; and I've topped off the resevoir with Dexcool which was kinda low. do you think if I drive the car for a day that the light might go off or do I have a bad sensor? Does the whole resevoir have to come out to replace the sensor? any idea on ballbark repair cost? my mechanic says $150
