Product Description

REMOVABLE RADIATOR CAP The radiator cap is responsible for keeping coolant inside the radiator, but it also operates as a two-way valve that keeps the right pressure inside the heater so it can work effectively. Keeping the coolant pressure is crucial to prevent the coolant from boiling and evaporating, which can cause an overheated engine.

I appreciate your kind words!

Part number 16401-31520, 1640131520 is replaced by this part. After obtaining the new cap, make sure your engine is cool before unscrewing the old cap and screwing on the new one.

A durable design constructed from premium materials. Cap is designed to work with open cooling systems and overflow reservoir type systems and allows the cap to be installed and removed much more easily.

The cap has been replaced with a brand new one

5/5

The radiator that I bought had a cap on it and was brand new. Because my hoses were being pulled in after cooling down, it wasn't functioning as it should.
