What is a Radiator Block Off Cap?

Material is an important factor; most caps are made from metal or plastic, but some are available in other materials such as rubber or silicone. The size of the cap should also be considered; it needs to fit snugly into your radiator in order for it to work properly. Finally, you should check for any additional features that may be offered with your chosen cap such as weatherproofing or corrosion resistance.

Price Range
Radiator block off caps vary greatly in price depending on their size and material used. Basic plug-in caps can range anywhere from $5-$20 while more complex designs can cost up to $50 or more. Pressure-release caps tend to be on the higher end of this range due to their special design and construction.

Where to Buy
Radiator block off caps can be purchased at most auto parts stores or online retailers such as Amazon or eBay. Its important to make sure you purchase the right size for your make and model of car before you buy so that you get a proper fit and seal when installing it on your vehicle.
