Ford uses UView's AirLift's vacuum test function to perform EGR cooler leak tests and an oil cooler leak tests on the F-Super Duty, Excursion and E-Series engines to help identify problems. The AirLift tool, No. 550000, can be used on more than just a vehicle's cooling systems. It is an effective and fast tool for eliminating airlocks and refilling cooling systems, including the heater core, and reduces the time it takes to do a cooling system service.
