Keep all protective caps on the EGR cooler in place while grinding clearance in the upper mounting bracket. Failure to do so could cause progressive damage to the engine once the EGR cooler is installed. It’s important to prevent any debris from entering the cooler.

Inspect for an interference fit between the upper EGR cooler mounting bracket and the lower portion of the exhaust manifold flange. If this interference is present, grind a clearance on the upper EGR cooler mounting bracket in the area shown in the illustration.
