To remove and install the oil pan, first, disconnect the negative battery cable and securely lift the front of the vehicle. Now, drain the oil pan, next pull apart power steering bracket from suspension crossmember. Then, separate stabilizer bar from transverse link and other tension rod from transverse link. Remove nuts attaching front engine mounting insulators to body then lift engine up. Loosen specified number of oil pan bolts in given sequence; further remove suspension cross member bolts and power steering oil tubes screws securing to cross member. Lower suspension cross member so as to provide enough space for removal of oil pan. Take seal cutter and fit it between cylinder block and oil pan, tap it lightly with hammer moving it around whole periphery of oil pan. Be careful not to thrust it into rear seal retainer portion or into
Oil Pump. Lower oil pan out of cylinder block toward front end ofengine. While installing clean sealing surfaces well and apply sealant on oil pump gasket as well as rear oil seal retainer gasket surfaces. Apply liquid gasket continuously around four corners of cylinder block mounting surface at an appropriate position for 5 minutes before installing pan on it. Tighten specified torque in sequence for all bolts in order for the oil pan bolt to be secured properly together. Lastly reassemble in reverse order; fill crankcase with proper amount of oil; connect negative battery cable; start engine; check leaks. In case of particular vehicle models like 200SX with VG30E engine removal entails draining the oil sump, removing engine mount insulator nuts & bolts, taking out center cross member assembly installed by unbolting the exhaust pipe connecting nuts that secure the sump flange from beneath . It involves cleaning sealing surfaces, applying sealant, putting back the cup along with its gasketing material, screwing down bowl fasteners uniformly until fully tightened up and lastly lowering assembly down onto mountings again once torque has been applied to nuts. Removal of stabilizer bars, covers and other model specific components is also carried out in similar manner for other vehicle models such as 240SX and Stanza with CA or KA24E engines.
