  • REPLACEMENT 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. Symptoms of a Bad Radiator Cap: air enters the system, low coolant level, coolant leaks, overflowing reservoir, overheating engine.
