What is a Radiator Cap?
- The radiator cap holds the coolant inside the radiator, but it also works as a two-way valve that keeps the right pressure inside so the radiator does it work correctly. If the pressure isn't maintained, the coolant can boil and evaporate, putting the engine at risk of overheating.
- Designed to function on open cooling systems and overflow reservoir type systems and allows the cap to be installed and removed much easier.
- Allows the cap to be installed and removed much easier than conventional radiator caps, because the shell of the cap rotates independently from the upper sealing gasket, stem and bottom plate.Once you have a replacement and your engine is cool, simply unscrew the old cap and screw on the new cap.
Feature:
- Designed for long service life under harsh conditions
- Designed for use in open cooling systems and overflow reservoir type systems
- Easier installed and removed than conventional caps
- 100% environmental, endurance and end-of-line testing for timing
- Meets original equipment specifications
- Ensure optimum performance and durability
- Strong reliability and drivability
Symptoms of a Bad Radiator Cap:
- air enters the system
- low coolant level
- coolant leaks
- overflowing reservoir
- overheating engine
Replacement tips：
- It is extremely important to always make sure to allow the engine to cool down before removing the radiator cap, as removing the cap from a hot system can cause sudden coolant spray and severe burns. A faulty radiator cap can have a huge impact on the cooling performance of your vehicle.

My coolant pressure wasn't allowing the coolant to recirculate properly, and I think changing the cap fixed it.The cap fit nicely and has good action.

The right fit

The radiator cap did not fit nor would I use it if it did because of the POOR QUALITY and thin metal used in its construction. The metal cap was so thin and dangerously sharp it would damage and cut in to 100% of plastic radiators in automobiles this is supposed to fit. Returned and bought another one.

Mine came stamped with the denso “ND†on it as one reviewer said theirs didn’t. Clearly, it is not a Denso, but no one will ever know except me

Take the old cap off. Put the new one on. Works great. No issues.
