Q: How to Maintain and Fix an Oil Pan on 2006 Jeep Liberty?
A: To deal with the oil pan, disconnect the negative battery cable, fit the engine support and hoist up the vehicle. Take off the front wheel assemblies and the skid plate (when it's present) and finally, empty the engine oil. Mark each bolt and bolt stud where it is now, remove all the FR mounting bolts, disconnect the LH tie rod, the LH lower ball joint and the clevis. Unbolt the axle brace and front axle from the LH and take out the front prop shaft. After that, drain the front axle. After lifting the front axle with a transmission jack, remove all the bracket bolts and carefully remove the front differential even though the RH axle is still mounted. Take out the transmission oil cooler line bracket and the engine to transmission stiffening bracket. Attach Special Tool 8534 where the fender meets the lip, adjust its brackets so their holes fit the mounting holes of the fender and secure the brackets with four M6 X 1.0 X 25 MM flanged cap screws. Turn the screws on your sleeves to lock them to the support tube and make sure the support tube is upright. Place the flat washer, thrust bearing, hook and T handle against the attention support bracket, then use the M10 X 1.75 mm flanged nut provided with the support fixture to attach the chain to the front engine lifting stud. Adjust the tension on the engine mounts, free the bolts connecting the oil pan and take off the oil pan while avoiding prying, because the gasket is a key part of the engine windage system. Shuffling the oil pan and windage tray forward, get rid of them from the engine. Soak the oil pan in solvent and remove the excess liquid when it dries. While drying, confirm that the gasket surface is not scratched. Inspect the oil drain plug, look for any sign of damage in the same area and check the oil pan mounting flange for bends, fixing the flange if it is bent. Wipe down the joint areas of the oil pan and bed plate, watch the oil pan gasket and switch it out if required. Tuck the oil pump pick-up tube into the oil pan, then put the oil pan, pick-up tube and windage tray together as one part in front of the vehicle. Set in place the windage tray, oil pump pick-up tube and attach them with the two nuts and the one bolt, after moving the oil pan as necessary for clear access. Secure the fittings at the end of the pick-up tube and next tighten all the bolts for the oil pan. Should the equipment be present, put the engine to transmission cover in place, lower the unit, then take out Special Tool 8534. Adjust the suspension and then bolt down both the engine mounts, followed by installing the transmission oil cooler mount bracket. Fill the oil back into the engine, secure the battery and then start the engine to search for leaks.
