The caps should always be in mint condition with no pressure leaks coming from the seal. Too little or too much pressure can cause damage to your vehicle’s working system.
Rating
A radiator cap rating maps how much pressure a cap can hold. After manufacturing, each cap is tested to determine how much pressure it can take. Using an associated pressure chart, it ensures correct labeling. All caps are not created equal. You would need to know the year, make, and model of your car to make sure you are buying the correct cap.
Where to Buy
Radiator caps can be found and bought in any car specialty store. Both online and brick and mortar stores carry various types. The cost is minimal, generally less than $100. As stated previously, you would need to make sure you know the make and model of your vehicle before purchasing.
