1. Disconnect the negative cable from the battery.
2. Set the parking brake and block the rear wheels.
3. Raise the front of the vehicle and support it securely on jackstands.
4. Remove the splash shields under the engine, if equipped.
5. Drain the engine oil and remove the oil filter (see Chapter 1). Remove the oil dipstick.
6. Disconnect the front exhaust pipe from the engine and remove the clamp behind the engine to allow the pipe to hang down.
7. Unbolt the crossmember which connects the lower suspension mounts, and then remove the crossmember under the oil pan (see illustrations).
8. Remove the block-to-transaxle brace (see illustration).
9. Remove the bolts and detach the oil pan. If it's stuck, pry it loose very carefully with a small screwdriver or putty knife (see illustration). Don't damage the mating surfaces of the pan and block or oil leaks could develop.
10. Use a scraper to remove all traces of old gasket material and sealant from the block and oil pan. Clean the mating surfaces with lacquer thinner or acetone.
11. Make sure the threaded bolt holes in the block are clean.
12. Check the oil pan flange for distortion, particularly around the bolt holes.
