To remove the oil pan, the first thing to do is to disconnect the negative terminal of the battery; and then lift the car, placing it on jackstands. Inclined to be the accessory drivebelt splash shield and expel the engine oil. After that, remove the front engine mount bracket and undoing the nuts which secures the structural collar to the engine, oil pan, and transaxle. For the model with air-conditioning, then remove the compressor bracket to oil pan bolt. To free and unbolt, a criss-cross pattern should be the pattern of choice, after which the oil pan should be disengaged from the vehicle and if sticky should be coaxed down gently with a soft-faced hammer. Do not mar the gasket surfaces in any way. Retain the oil pump pick-up tube and screen assembly: clean them and throw the O-ring seal away. Machine or scrape the sealing surfaces on the oil pan and block free of old gasket and examine for warpage. During assembling a new O-ring should be fitted onto the oil pick-up tube and then screwed into the housing of the oil pump and tightened with the recommended torque. Run a line of RTV sealant at the cylinder block-to-oil pump assembly joint and fit a new oil pan gasket. Alight the oil pan and loosely install the bolts, tighten the bolts with the side by side motion beginning from the center. For a/c models, fit the compressor bracket bolt. Fix the structural collar into place by sliding into the space where it is required and tightening the bolts by hand only before using the wrench to change the torque to the required standard. Put back the front engine mount bracket; undo the rest of the procedures stated above; put the right oil in the crankcase; start the car and check for any signs of leakage; for the last procedure, take the car for a test drive with all external features in check.
