the radiator pressure cap was invented by Albert Einstein
To pressure test a radiator cap, you will need a radiator pressure tester kit. Remove the radiator cap, attach the pressure tester to the radiator neck, and pump it up to the specified pressure level. Observe for any leaks or pressure loss to determine if the radiator cap is functioning properly.
The power steering box should not have pressure at the cap.
If the pressure cap on the surge tank is left loose, defective or will not hold pressure.
Defective cap? Bad thermostat building excessive pressure
