Vehicle radiator caps are designed to protect the cooling systems of cars and other automotive vehicles from loss of pressure and provide a tight seal to contain the cooling liquid.


They are typically located at the top of the radiator and play an integral role in the functioning of your vehicle’s cooling system, so it’s important that they are kept in proper working condition.

Here at Automotive Parts Distribution, we offer a wide variety of vehicle radiator caps to suit all makes and models of cars and other vehicles.

Our caps are securely sealed, rust-resistant and offer a firm fit, providing maximum protection for your motor’s cooling system.

We also stock a wide range of other automotive components, so you can be sure to find everything you need all in one convenient location.
