Your Buick Roadmaster radiator is the core of your vehicle's cooling system. The Roadmaster radiator reigns supreme, front and center in your engine bay. The purpose of your Buick Roadmaster radiator is to disperse, or radiate, the heat your coolant absorbs as it travels through your engine.

Your Roadmaster radiator accomplishes this task by allowing the heated coolant to spread through a series of tubes and passages hidden beneath horizontal or vertical fins, which give the coolant a greater surface area. In addition to the heat released through the spreading of the liquid and the additional surface of the fins, your Buick Roadmaster radiator benefits from air blowing through your front grille as your vehicle travels.

When you are stopped in traffic, the Roadmaster radiator makes use of an auxiliary cooling fan mounted behind the body of the radiator to assist in heat dispersion. The radiator fan is controlled either through a small electric motor or a fan clutch attached to the water pump belt. In either case, the Roadmaster radiator fan is automatically activated when the temperature of the coolant reaches a certain point. You should maintain your vital radiator through regular flushing and cleaning according to the manufacturer's recommendations to prevent debris buildup within the tubes and passages. However, like all working parts, your Roadmaster radiator is going to wear out over time. The radiator may develop leaks from corrosion, or it may be damaged in a front-end collision.In any case, if your Roadmaster radiator is leaking, pick up a high quality replacement radiator from our extensive online catalogue, and save time and money by installing it yourself.
