Pontiac Sunfire Replacement Expansion Tank Information


Coolant expands when exposed to heat. There is not enough space in the radiator for the expanded coolant, so it must have a place to go, which is the expansion tank. If you have a leak in this tank, which is the reservoir for extra coolant, you may lose engine coolant, which could ultimately cause your engine to overheat. You can get a new expansion tank that will fit your Pontiac Sunfire by searching for it here. If you also need new radiator hoses, coolant or a radiator, you can also find those here. To be sure that you are getting the right cooling system parts, look for them by the make, model and year of your vehicle. Purchasing a Pontiac is an intelligent choice, now maintaining it in top condition is a great choice!
