  Q: How to service and repair the oil cooler on Mercury Grand Marquis?

  A: Prior to maintaining the oil cooler drivers must power down any installed fire suppression system. The vehicle needs to be set to NEUTRAL position on a hoist before draining the cooling system. Industrial engine oil lubrication must be applied to the new oil filter's O-ring seal before integration into the system. The service requires you to remove the oil cooler hose bolt and disconnect the oil cooler hoses from the oil filter adapter before tightening them to 10 Nm (89 inch lbs.) when reinstalling. Metallic particles or pieces of aluminum within the oil cooler or hoses suggest the presence of mechanical problems. See and inspect the oil cooler during the procedure by first loosening two coolant hose clamps to detach the coolant hoses then remove the oil cooler and hoses as one assembly. Complete necessary inspection then repair work before doing the reverse procedure for device reinstallation and power up if the vehicle contains fire suppression system.
