- RADIATOR CAP FUNCTION :The radiator cap holds the coolant inside, 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. Symptoms of a Bad Radiator Cap: air enters the system, low coolant level, coolant leaks, overflowing reservoir, overheating engine.
- HIGH-PERFORMANCE:100% brand new factory packaging, all materials we use have been tested for performance, reliability and durability.Designed to function on open cooling systems and overflow reservoir type systems and allows the cap to be installed and removed much easier.
