To change an oil pan, locate the drain bolt on the bottom of the oil pan, remove the bolt, and drain the oil into a drain pan. Use a ratchet and socket to remove the screws bolts securing the oil pan in place. Set the bolts in a secure location. Scrape the gasket off the connection on the vehicle with a putty knife. Install the new gasket, and bolt the new oil pan into place.
Clean the connection point thoroughly with a recommended solvent before installing the drain pan, and check the drain plug to ensure it is secure before adding the recommended type and amount of oil to the vehicle. Refer to the owner's manual for additional information on the type and amount of oil to add.
Liquid gasket is an alternative to traditional gaskets. Avoid covering the holes in the oil pan with the gasket material. After adding the oil, place a clean piece of cardboard under the oil pan, and start the engine. Allow the engine to run for several minutes to check for leaks.
When recommended in the owner's manual, use a thread sealing compound on the bolts securing the oil pan. Drain the oil into an approved container, and dispose of it according to local regulations.
