CAUTION:
To prevent engine damage, use care when installing the high-pressure pump cover with fasteners. The three bolts in the cover can fall out of the cover and into the engine under the high-pressure pump.
CAUTION:
To prevent engine damage, the high-pressure oil pump cover must be firmly seated on the O-ring seal to prevent cracking the cover plate.
NOTE:
Use a tool such as the Snap-on FRDH101 or GFRDH101 to aid in accessing the bolts under the exhaust gas recirculation (EGR) cooler.
NOTE:
Apply clean engine oil to the high-pressure oil pump O-ring seal prior to installing the high-pressure pump cover.
