How to conduct a leak test on the EGR Cooler on Ford F-350 Super Duty?

A leak test of the Exhaust Gas Recirculation (EGR) cooler requires you to install either the original mounting fasteners or buy M8 fasteners from a local vendor. The EGR cooler Test Plates must be installed at each end of the cooler using 4 M8 bolts with corresponding nuts which need tightening up to 31 Nm (23 lb-ft). During testing avoid applying a pressure greater than 207 kPa (30 psi) since high pressure will harm the EGR cooler. Activate the regulated air supply and rise the air pressure to 207 kPa (30 psi) before closing the supply. Dip the complete EGR cooler into water while examining for air bubbles to escape from the coolant paths. A new EGR cooler assembly becomes necessary if leaks are discovered in this process. Yet, if no leaks appear the assembly can be put back into service.
