How to Tell If a Radiator Cap Is Bad?

Answer

If you have any issues with your vehicle overheating, one of the first things you should check is the radiator cap. They are fairly inexpensive to replace. If you have bubbles in the coolant expansion reservoir, that may be telling you that you have a bad radiator cap, If you know you have enough coolant and you replaced the radiator cap and you're still having problems, then the next step is to look at the head gasket.
