As the coolant operating temperature increases, the expanding (heated) excess coolant is forced out of the radiator, past the pressure cap, and
intotheoverowbottle.Astheenginecoolanttemperaturedecreases,thecontracting(cooled)coolantisdrawnbackupfromthetank,pastthe

NOTE:
Some coolant level drop on new vehicles is normal as the system is purging itself of trapped air. Observe coolant levels and maintain as

Adding or Changing Coolant
To ensure that the coolant maintains its ability to protect the engine, we recommend that the system be completely drained every two years and

Any time the cooling system has been drained for maintenance or repair, replace the coolant. If the recovery bottle has run dry, the level in the
radiator should be inspected. Add coolant as needed.
