  Q: How to service and repair the oil pan on Mercury Cougar?

  A: Service and repair of the oil pan requires users to begin by unplugging the battery ground cable alongside heat shield removal. Begin by unrusting the upper bolt then remove the coolant hose bracket followed by the engine-lifting eye and engine oil dipstick tube. To begin removal of the A/C tube/hose equipment one should disconnect its bracket then unfasten the lower bolts. Start the service by disconnecting the Three Way Catalytic Converter from the exhaust manifold followed by vehicle lift then removal of the TWC by unhooking its rubber mountings after taking out the bolt and retaining clip. The technician disconnects the Heated Oxygen Sensor (H02S) electrical connector then takes off the TWC from its bracket allowing engine oil drainage from the drain plug before removing all six oil pan bolts. A sharp spatula and light hammer movement should be used to separate the oil pan from the lower crankcase without damaging the mating faces. Installation begins with cleansing the mating faces to remove all traces of old sealer after their oil and gasket residue is removed. Clean the oil pan with solvent. Install studs (M6 x 20) in dead end bores of the oil pan then apply 3 mm silicone gasket and sealant to the mating face before installing the pan within 10 minutes without touching anything afterward. Crank the indicated bolts following two steps which start with 6 Nm force in stage one then move to 10 Nm force in stage two. You should reinstall the TWC by guiding it to the exhaust manifold studs while attaching it to the bracket and connecting the HO2S electrical connector and rubber mounting before securing it to the exhaust with proper contact against the exhaust manifold. First secure the retaining clip for the TWC before you install the bolt. Afterward you should lower the vehicle to attach the TWC to the exhaust manifold. Begin by installing the heat shield then add the oil level indicator tube into the cylinder block followed by placing the coolant hose bracket and engine lifting eye. Secure the upper bolt/nut while installing all lower bolts and then install the bracket to the A/C line. The tank should receive engine oil according to its fill level instructions and oil type requirements. Some abnormal drive symptoms will appear after battery reconnection as the vehicle learns its adaptive strategy during which driving at least 16 km (10 miles) could be necessary. Verify fluid levels while also making necessary adjustments before securing vacuum hoses and wiring according to the cable tie procedure.

  Q: How to service the oil pan safely and effectively on Mercury Grand Marquis?

  A: Before working on the oil pan service it is essential to depower the fire suppression system to prevent serious personal injury. The front crossmember must be removed following a hoisting operation of the vehicle which should be currently in NEUTRAL gear. Disconnect both the bolt and the nut before setting the transmission cooler tubes to one side. The engine drain plug requires installation by tightening it to 23 Nm (17 lb-ft). Remove the two pin-type wire harness retainers before removing bolts from their specified sequence to detach the oil pan gasket together with the pan. Install the gasket surfaces by using a plastic scraping tool instead of metal scrapers or abrasive tools to remove sealant residue before inspection. The correct application of silicone gasket at the rear seal retainer-to-cylinder block joint together with engine front cover-to-cylinder block interface should occur within a 4-minute timeframe to prevent oil leakage. Start by installing the oil pan gasket together with the oil pan before proceeding to tighten bolts first to 20 Nm (177 lb-in) and further rotating them by 60 degrees. Reinstall wire harness retainers then place transmission cooler tubes next to each other before installing the bolt and nut which requires torque to 15 Nm (133 lb-in) and the nut requires 9 Nm (80 lb-in). The last step includes filling the engine with fresh oil and beginning the engine to inspect for fluid escapes followed by fire suppression system repowering according to all warning guidelines.

  Q: How to service and repair the oil pan on Mercury Mariner?

  A: Service and repair of an oil pan begins with positioning a vehicle on a hoist with it set to NEUTRAL. Detach the Air Cleaner (ACL) outlet pipe before you loosen the 2 bellhousing-to-engine bolts by 5 mm (0.19 in) which must not exceed this distance to protect the transmission. When working on AWD vehicles you should loosen the 2 RH engine-to-bellhousing bolts together with the 2 RH engine bracket-to-Power Transfer Unit (PTU) bolts to the same amount. After removing the 7 retainers along with the LH splash shield the technician should loosen the 2 LH bellhousing-to-engine bolts. Front Wheel Drive (FWD) drivers should loosen between 1 manual transaxle or 2 automatic transaxle RH engine-to-bellhousing bolts by 5 mm (0.19 in). Drain the engine oil while removing both bellhousing-to-oil pan bolts together with the two oil pan-to-bellhousing bolts because this action allows you to move the transaxle backward by 5 mm (0.19 in). Reinstall the drain plug before tightening it to 28 Nm (21 lb-ft). Disconnect the combination of 4 bolts joining the engine front cover to the oil pan while also removing the 13 bolts holding the oil pan. A plastic scraping tool should replace metal scrapers for cleaning all sealing surfaces during installation. Any delay in securing the oil pan after sealant treatment requires cleaning of the sealing area and waiting for it to dry. The installation process requires a 2.5 mm (0.09 in) strand of silicone gasket and sealant placed between the engine block and oil pan as well as the front cover of the oil pan. Mount the oil pan onto the engine block while keeping the bolts loose at first. Tighten the 4 engine front cover to oil pan bolts to 10 Nm (89 lb-in) before progressing with the oil pan bolt tightening at 25 Nm (18 lb-ft) using the specified bolt order. The tightening sequence for FWD vehicles includes alternately tightening 1 LH bellhousing-to-engine and 1 RH engine-to-bellhousing bolts to slide transaxle and engine together until they reach 48 Nm (35 lb-ft). Within the AWD configuration alternate tightening the 1 RH engine-to-PTU bracket bolt with the 1 LH bellhousing-to-engine bolt then torque the PTU bracket bolt to 45 Nm (33 lb-ft) and the LH bellhousing bolt to 48 Nm (35 lb-ft). Install the two bellhousing-to-oil pan bolts as well as the two oil pan-to-bellhousing bolts while torquing them to 48 Nm (35 lb-ft). Reinstall the LH splash shield by securing seven retainers to 9 Nm (80 lb-in) and fasten the 2 RH engine-to-bellhousing bolts to 48 Nm (35 lb-ft) in addition to tightening the 2 upper bellhousing-to-engine bolts to 48 Nm (35 lb-ft). For the completion install the ACL outlet pipe and then add clean engine oil into the engine.
