The low coolant and service engine light keeps coming on my daughter's 97 grand prix. The car is a salvaged/damaged car that was rebuilt. (If that matters) The auto mechanic said the computer says its a possible egr valve that is making the light come on, but then it goes off. The low coolant light is doing the same, even thought it has coolant. Also the car has a heads up display and a picture of a battery will come and go on the heads up display. It is strange. It has a new battery. My question is. IF it is an egr valve, will it leave her stranded, or just affect the gas mileage? Also, if there is coolant in the reservior and radiator, will the car still over heat and ruin the engine? I don't know how long she will have this car so I don't want to spend a ton of money on it isn't a huge deal. I realize it has a lot of miles on it, and was salvaged, but all in all it runs very well. I just don't want her to be stranded. Thanks so much.
have the same problem?
