Pressure Testing - On Vehicle

^ Pressure-test the aluminum-plastic radiator with J 24460-01, or equivalent.
^ With the system at a cool temperature, remove the radiator cap, connect the gage, and apply normal system operating pressure.
- Do not exceed 138 kPa (20 psi).
^ Watch the gage needle for an indication of a leak, and examine the radiator and other cooling system parts for escaping coolant.
^ Repair hose and hose connections as required.
^ Check the radiator cap to ensure that it will maintain the correct pressure.
^ If the radiator leaks during the pressure test, mark the leak area.
