Radiator: Testing and Inspection
Leak Testing - On-Vehicle
NOTICE: Pressures above 138 kPa (20 psi) should not be used when testing the cooling system. Pressures over 138 kPa (20 psi) will damage the
radiator.
Pressure-test the aluminum-plastic radiator with J 24460-01. 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.
