6.0L HPOP Supply Inlet Screen
At the bottom of the oil cooler reservoir is the high pressure oil pump oil feed passage. The screen that filters the oil going to the HPOP can be brittle and sections may become unsecured and in some cases completely separate. It is important when servicing oil coolers to prevent dirt and other debris from entering this reservoir and ensure it is completely clean before reassembly. Always install a new screen which has been updated to a stainless steel design.
