How to service the oil cooler on all engines on Mercury Grand Marquis?

The first step when servicing the oil cooler requires releasing the fire suppression system to avoid severe personal injury. Position the vehicle under a hoist system before draining the cooling system liquid. A newly manufactured oil filter needs a coating of clean engine oil before placement on its O-ring seal to ensure proper installation. Engineers building at an early stage should remove the oil cooler hose bolt before disconnecting the cooler hoses from the oil filter adapter while tightening the fittings to 10 Nm (89 lb-in) torque. Thoroughly inspect the oil cooler and hoses after hose removal because finding metal or aluminum indicates mechanical issues that threaten severe engine damage to the system. The white lines on late build coolant hoses need to be parallel with black dots on oil cooler tubes when disconnecting and installing these hoses. Clean engine oil should be applied to the O-ring between the oil filter and cooler adapter before its installation where torque should reach 46 Nm (34 lb-ft). Reverse both the removal process and power up the fire suppression system according to safety guidelines to stop serious personal injury.

The drain of engine oil requires removing the oil drain plug before retightening this component to 28 Nm (21 ft. lbs.).

The gasket requires disposal before removing the 4 oil filter adapter bolts that need tightening to 25 Nm (18 ft. lbs.) when readjusting. Metals and aluminum present inside the oil cooler during inspection would reveal mechanical problems in the system. The operator should clamp the oil filter adapter across a vise before unfastening the oil cooler bolt and removing the oil cooler for inspection. The technician should secure the oil cooler by tightening it to 34 Nm (25 ft. lbs.) during reinstall and follow the initial removal steps in reverse order. You must complete the engine cooling system filling process while bleeding it before you introduce fresh clean engine oil into the system.
