Radiator Cap: Description and Operation
Radiator Cap - Description
DESCRIPTION
CAUTION: Vehicles equipped with 2.0L/2.4L engines use a different pressure cap than vehicles equipped with 2.7L engines. The pressure caps
are NOT interchangeable. Verify proper pressure cap part number.
The cooling system is equipped with a pressure cap that releases built up pressure, maintaining a range of 97-124 kPa (14-18 psi).
There is also a vent valve in the center of the cap. This valve also opens when coolant is cooling and contracting, allowing coolant to return to radiator
from coolant reserve/recovery system container by vacuum through connecting hose. If valve is stuck shut, the radiator hoses will be collapsed on
cool down. Clean the vent valve to ensure proper sealing when boiling point is reached.
