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.

How to service the oil cooler on Mercury Mariner?

The first step to service the oil cooler requires placing the vehicle on a hoist with neutral engaged position. The right-hand splash shield requires five bolts to remove before replacement during which you must tighten each bolt to 9 Nm (80 inch lbs.). The drain of engine oil requires removing the oil drain plug before retightening this component to 28 Nm (21 ft. lbs.). After removing the oil filter you must tighten the new filter three quarters of a turn after the filter gasket meets the oil filter adapter. The engine cooling system needs drainage and workers must disconnect both coolant hoses that connect to the oil cooler before removing the oil pressure sender electrical connector. 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.

Mercury Oil Cooler maintains a smart, consistent temperature of engine oil in order to have power on board. Mercury was born in 1938 showrooms and created a name for itself with sleek midsize rides and hushed cabins. The design and fast reaction on the road and the name, which was borrowed from the fleet Roman messenger, were able to be fast. Customers were assured of bumps being absorbed by means of suspension as steering remained straight. The interiors were smooth and dampened road noise as well so that long trips would seem shorter. Over decades, Mercury struck a balance between comfort and value, introducing Cougars, Grand Marquis sedans, and other models without being overloaded with features and coming at an elevated price. The spirit of Mercury lives on even after production ceased in 2011 in features that protect performance and durability. Mercury owners continue to rely on the company to ensure that they live longer and maintain the luxurious ride they associate with it. Oil Cooler units use the flow of coolant through the engine, extract the heat in the lubricant on hard towing or steep climbs, and recirculate it at an optimal viscosity to provide the film strength and friction control on sweltering days when the gauge is slowly rising. The design of the Oil Cooler is such that it uses strong plates and safe fittings that can withstand the same vibrations that have previously shaken factory cores into leaks. The Oil Cooler removes excess temperature which causes bearings and cams to be starved by oil thinning. Drivers that install an Oil Cooler experience consistency in pressure, extended oil life, and tranquility whenever making a heavy haul.
