  A:

  Warm up the engine, then drain the oil and remove the oil filter. Detach the cable from the negative battery terminal. Caution: On models equipped with the Delco Loc II audio system, be sure the lockout feature is turned off before performing any procedure that requires disconnecting the battery. Raise the vehicle and securely support it on jackstands. Remove the exhaust pipe shield. On air-conditioned models, remove the air conditioner brace at the starter and compressor bracket. Remove the starter and bracket. Remove the lower bellhousing cover. On air-conditioned models, remove the air conditioner brace. Remove the four right support bolts. Lower the support slightly to gain clearance for oil pan removal. Remove the oil filter extension (automatic transaxle equipped models only). Remove the bolts and nuts securing the oil pan to the engine block. Tap on the pan with a soft-face hammer to break the gasket seal, then detach the oil pan from the engine. Using a gasket scraper, remove all traces of the old gasket or sealant from the engine block and oil pan. Make sure the threaded bolt holes in the block are clean. Wash the oil pan with solvent and dry it thoroughly. Check the gasket flanges for distortion, particularly around the bolt holes. If necessary, place the pan on a block of wood and use a hammer to flatten and restore the gasket surfaces. Clean the mating surfaces with lacquer thinner or acetone. Place a 2 mm diameter bead of RTV sealant on the oil pan-to-block sealing flanges and the oil pan-to-front cover surface. Apply a thin coat of RTV sealant to the ends of the rear oil pan seal down to the ears. Press the oil pan seal into position. Carefully place the oil pan against the block. Install the bolts/nuts and tighten them in 1/4-turn increments. Start with the bolts closest to the center of the pan and work out in a spiral pattern. Don't overtighten them or leakage may occur. Reinstall components removed for access to the oil pan. Add oil and install a new filter, run the engine, and check for oil leaks.
