Radiator Caps


Radiator Caps

Yogi's Inc. offers a large assortment of radiator caps.  They are finished in Polished Aluminum and Chrome Plated Finish.  We sell from only the best manufactures sure as Vintique, Walker, Sun Spec and Billet Specialties.

Choose radiator caps from 7 to 16 lbs, in several styles and colors.

Did You Know:

Your radiator cap is an important part of the cooling system. It is designed to hold a certain amount of pressure inside the system, and to release the pressure when it exceeds a pre-determined level. Why do you want pressure in the cooling system? Actually, you don’t get a choice. As the coolant heats up, it expands. Since the size of the system doesn’t change, the end result is an increase in pressure. However, the positive impact is that the boiling point of the coolant increases as the pressure increases. Straight water at atmospheric pressure boils at 212 degrees Fahrenheit. A mix of 50/50 coolant and water boils at around 220 degrees. That same mix at 16 pounds per square inch (psi) of pressure boils at approximately 250 degrees because the boiling point of your coolant increases 2-3 degrees for each psi of pressure in the system. Always use the cap pressure rating that is recommended for your car and its cooling system.
