Are radiator caps universal?

Radiator caps can come in all shapes and sizes unique to your car’s radiator. Different vehicles have different systems and therefore work with individual pressures.

How does a motorcycle radiator cap work?

The cap regulates the maximum pressure, preventing damage to the hoses and radiator. After turning the engine off, the system cools and the coolant contracts significantly. The cap therefore has a return valve that admits air from the atmosphere or coolant from an expansion tank, if fitted.

Can I use 1.3 bar radiator cap?

In particularly hot areas with engines that are running high compression or boost, a 1.3 bar radiator cap, water wetter and a reasonable coolant ratio or distilled water setup would be a good “stock upgrade” to help prevent detonation.

What psi should my radiator cap be?

Most radiator pressure caps keep the system pressure at 16 PSI so the engine coolant can get considerably hotter without the fear that it will boil off.

Is a higher pressure radiator cap better?

And the boiling point increases 2-3 degrees for each additional psi of pressure in the system. So the over-simplified answer to the tech quiz is that, yes, a higher pressure radiator cap can help prevent overheating.

What psi should radiator cap be?

How do I know what size radiator cap I need?

Know the Pressure Rating Each cap is different depending on the model of your car. The owner’s manual often has the correct pressure rating listed that is necessary for your car. If the pressure rating is not listed in the owner’s manual, it will be under the hood on top of your old radiator cap.

What psi radiator cap should I use?

Use one with the psi rating that the rest of your cooling system was designed for. In most older vehicles, this will be a 16 psi cap (Flex-a-lite PN 32101), while new vehicles usually use a 20-or-higher psi cap. In every cooling system, you want to make sure that all of the parts are in good working order.

Can I use a higher psi radiator cap?

If your current cooling system is running well and doesn’t overheat, a high-pressure cap is unnecessary. It won’t hurt anything. But it won’t help either.
