Reservoir Caps


What is the reservoir cap?

The car's reservoir cap is like a pressure regulator and safety valve for your engine. The same concept applies to the pot, keeping its contents at an optimum level so that you don't risk burning too much, too much force, or boiling over!

How much does a reservoir cap cost?

Reservoir caps can cost as low as $22 up to $75. It depends on the brand and type.
