  Q: How to Service and Repair the Engine Front Timing Cover on Mercury Montego?

  A: Maintenance of the engine front cover must be performed with clean conditions to stop engine failure from foreign objects. Placing the vehicle on a hoist in NEUTRAL position while grounding the battery is the first step. You must remove the crankshaft front seal and left-hand and right-hand valve covers together with the bolt and accessory drive belt tensioner before unfastening the three power steering pump nuts then putting away the power steering pump along with fluid reservoir. Disconnect the crankshaft position (CKP) sensor and camshaft position (CMP) sensor electrical connectors and proceed to remove the two generator-to-engine front cover stud nuts and studs. Remove the three pin-type retainers and the radiator splash shield before unfastening both A/C compressor bolts and nuts while supporting the unit with mechanic's wire. To proceed remove the two bracket-to-engine front cover bolts from the A/C compressor followed by separating the ground wire from the engine front cover stud bolt and removing the two Oil Pan-to-front cover bolts. You should first discard the gaskets together with the engine front cover and fifteen bolts along with the stud bolt. Usage of silicone gasket remover along with a plastic scraping tool is required for sealing surface preparation before installation but metal scrapers or abrasive tools must be avoided. Place three new gaskets on the front cover followed by application of 6 mm (0.23 in) diameter silicone gasket and sealer dots on mating surfaces. Place the engine front cover in position before installing all fifteen bolts and the stud bolt with a torque of 25 Nm (18 lb-ft) according to their installation sequence. Secure both oil pan-to-front cover bolts with 25 Nm (18 lb-ft) torque before draining the engine oil through removing and reinstalling the oil pan plug at 26 Nm (19 lb-ft). Secure the ground wire at the engine front cover stud bolt and apply 20 Nm (15 lb-ft) torque to the nut. Position the A/C compressor before installing both bolts and two nuts to 25 Nm (18 lb-ft). Fasten the radiator splash shield first with its three pin-type retainers before tightening the two generator-to-engine front cover studs up to 8 Nm (71 lb-in) then the two generator-to-engine front cover stud nuts to 48 Nm (35 lb-ft). Install the power steering pump along with its fluid reservoir before secure the three power steering pump nuts to 25 Nm (18 lb-ft). Position the accessory drive belt tensioner along with its bolt, apply torque of 45 Nm (33 lb-ft), reinstall both valve covers and the crankshaft front seal before filling the engine with new clean engine oil and reattaching the battery ground cable.
