The Stop Shop Radiator Coolant Overflow Bottle Caps
The Stop Shop offers radiator coolant overflow bottle caps with the correct design as the originals found on late model vehicles, including the 1974-1975 and 1980 Camaros and other late model vehicles. Benefits of these radiator coolant overflow bottles caps are primarily related to their role in the proper functioning of your vehicle's cooling system, as the cap provides a seal to the radiator and coolant system, preventing leaks and maintaining the integrity of the closed system. These caps are designed to help regulate pressure, prevent boiling and air from entering, and allow for proper coolant recirculation, all of which are vital for a healthy engine and efficient cooling.

Radium Engineering Coolant Tank Kits
Because of continuous and intense heat cycling, plastic coolant tanks have a reputation of failing over time. Radium Engineering cooling tank kits feature a rugged 2-piece tank CNC-machined from aluminum and anodized for increased longevity. And because aluminum is a superior thermal conductor material, heat transfer is further improved. The tank functionality remains the same as the OEM cooling system, and the tank's internal design has two chambers with crossover passages at the top and bottom, as well as an internal swirl feature aiding in de-aerating the system. The kits include a specially designed mounting bracket that secures to existing threaded holes and Radium adapter fittings to interface with the factory lines. No permanent vehicle modifications are required. Radium Engineering cooling tank kits are available to fit several years, makes, and models and will include tank, bracket, adapter fittings, hose, and stainless steel hardware.
