To remove and install the transaxle pan, first raise and support the vehicle on jackstands, then place a container under the transaxle to catch the oil when the pan is removed. Next, remove the transaxle pan bolts, and if the pan sticks, gently bump it with a soft hammer to break it loose. Clean the gasket mounting surfaces using a putty knife. For installation, use a new gasket and sealant, then reverse the removal process, ensuring to torque the oil pan bolts evenly to 3.6-5.1 ft. lbs. and refill the transaxle. Regarding filter service, the oil strainer typically does not need replacement under normal operation; changing the transaxle fluid suffices for maintenance. Begin by removing the oil pan, then take out the oil strainer plate bolts from the control valve body assembly to remove the oil strainer, noting that on some later models, disassembly of the transaxle assembly may be necessary to access the strainer. For installation, follow the reverse of the removal process, tightening the oil strainer retaining screws evenly and replacing any gasket for the strainer mounting.

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.

Next, remove the engine drivebelts and the lower idler pulley bracket, followed by the alternator and power steering pump. Ensure the power steering pump bracket is also removed. Take out the crankshaft position sensors from the front timing chain cover and transmission bellhousing.

Disconnect the cable from the negative terminal of the battery and raise the vehicle, securely supporting it on jackstands. If equipped, remove the engine under-cover.

Apply a continuous 5/32-inch (3.5 mm) bead of RTV sealant to the inner sealing surface of the oil pan. Install the oil pan and tighten the bolts in three or four steps following the sequence to the specific torque.

Remove the remaining bolts and drop the pan.

The remaining installation steps are the reverse of removal. Allow at least 30 minutes for the sealant to dry, add oil and a new oil filter, start the engine, and check for oil pressure and leaks.

Remove the oil pan bolts, following the reverse of the tightening sequence. Detach the oil pan. Don't pry between the pan and engine block to prevent damage to the sealing surfaces.

Examine the lower steel oil pan flange for distortion, particularly around the bolt holes, and flatten it if necessary.
