To remove the oil pan on 2WD models, the engine must be removed. First, if the vehicle has air suspension, turn the switch OFF before raising it. Disconnect the negative battery terminal, remove the oil dipstick, drain the engine oil, and remove the oil filter. Raise the vehicle securely on jackstands, then remove the engine mount through-bolts. Raise the engine about two inches using an overhead support fixture or crane, avoiding using a jack under the oil pan to prevent damage. Disconnect the electrical connector from the low oil level sensor if equipped. For 4WD models, the front differential must be removed. Remove the oil pan-to-transmission bolts and the oil pan-to-engine bolts, noting to place a block of wood between the engine and mount. Carefully remove the oil pan, breaking the seal with a thin putty knife if necessary, and clean it out with solvent. For installation, remove all traces of old gasket material and sealant from the pan and engine block, clean the mating surfaces, and use gasket adhesive to hold the rear rubber seals in place. Create alignment dowels from long bolts, apply RTV sealant, and position the pan against the engine block, installing the bolts finger tight before tightening them to the specified torque. Replace the alignment studs with pan bolts, then install and tighten the pan-to-transmission bolts. Finally, refill the engine with oil, install a new oil filter, start the engine, and check for oil leaks at the oil pan, driving the vehicle to check again.

Disconnect the negative battery cable from the battery, then remove the air cleaner assembly. Drain the engine oil and remove the oil filter, followed by the engine cooling fan assembly and shroud. For 4WD models, remove the front axle assembly. On models through 2003, attach an engine support fixture to the engine lifting eyes adjacent to the exhaust manifolds, and raise the vehicle securely on jackstands. Remove the oil level dipstick, then raise the engine slightly with the support fixture and remove the engine mount through-bolts. Continue to raise the engine gradually, ensuring no interference with engine compartment components, and when raised about two inches, place short lengths of 2x4 lumber between the motor mounts and the crossmember for safety. On 2005 and later Expedition/Navigator models, remove the four bolts/nuts and take out the front crossmember for clearance to remove the oil pan. Remove the oil pan mounting bolts and lower the pan to the frame cross member, then carefully separate the oil pan from the engine block using a large rubber mallet or a wood block and a hammer to avoid damaging the sealing surfaces. The oil pan gasket is reusable if care is taken during removal. Use a gasket scraper or putty knife to remove all traces of old gasket material and sealant from the pan and engine block, being careful not to gouge the surfaces. Clean the mating surfaces with lacquer thinner or acetone, ensuring the bolt holes in the engine block are clean. Apply a bead of RTV sealant to the four corner seams where the rear seal retainer meets the engine block and the front cover meets the engine block. Carefully position the oil pan against the engine block and install the bolts finger tight, ensuring the gaskets haven't shifted, then tighten the bolts to the specified torque, starting at the center of the oil pan and working outward in a spiral pattern. The remaining steps are the reverse of removal, and remember to refill the engine with oil before starting it. Finally, start the engine and check carefully for oil leaks at the oil pan, driving the vehicle and checking again.

Disconnect the cable from the negative battery terminal, remove the oil dipstick, drain the engine oil, and remove the oil filter. Raise the vehicle and secure it on jackstands, then remove the crossmember bolts and the crossmember. Take out the engine mount through-bolts and raise the engine about two inches with an engine hoist properly attached to the lifting brackets, avoiding the use of a jack under the oil pan to prevent damage. Remove the oil pan-to-transmission bolts and the oil pan-to-engine bolts, then take off the oil pan, breaking the seal if necessary with a thin putty knife while ensuring not to gouge the sealing edge. Empty any residual oil from the pan and clean it with solvent. For installation, use a gasket scraper or putty knife to remove old gasket material and sealant from the pan and engine block, clean the mating surfaces, and use gasket adhesive to hold the rear rubber seal in place. Stick the side gaskets on the engine block with adhesive and apply RTV sealant at the corners where the side gaskets meet the end seals. Create alignment dowels from two long bolts, apply a bead of sealant on the block and front cover, and ensure the oil pan is installed within 15 minutes to prevent the sealant from hardening. Position the pan against the engine block, install the bolts finger tight, and then tighten them in the correct sequence, replacing the alignment studs with pan bolts. Complete the remaining steps in reverse order, remembering to add engine oil and install a new oil filler. Start the engine and check for oil leaks at the oil pan, then drive the vehicle and check again.

Apply a 7/32-inch (5.5 mm) bead of RTV sealant at the junctures of the rear main seal housing and the block, and also where the pan meets the front cover.

Attach an engine support fixture to the engine lifting eyes adjacent to the exhaust manifolds. Note: Many equipment rental yards rent engine support fixtures.

Use a gasket scraper or putty knife to remove all traces of old gasket material and sealant.

Disconnect the cable from the negative battery terminal.
