Before removing the engine one has to disconnect the negative terminal of the battery and drain the engine oil. For easy working on the area of the oil pan, it is recommended that you lift the vehicle on a jack and put on support stands. Take the bolts out and pull the engine undercover; next grab the exhaust pipe clamp bolt and separate it from the pipe bracket. Subsequently, undo the four retaining bolts of stiffener plates on each side of the engine and pull out the flywheel inspection cover. Place an engine hoist beneath the vehicle and use hooks to hook to the two red clips on the engine at the frame, unscrew the two nuts connecting the engine to the car and slightly lift the engine. Take out the oil pan retaining bolts; if the pan does not come off, use a knife blade and hammer to cut around the gasket and loosen the bond, avoiding to scrape the gasket faces. Installation before cleaning the sealing surfaces, using gasket scraper, remove old gasket material and sealant on the pan and block. To clean the bolt and sealing patterns, you should dip a cloth in lacquer thinner or acetone. Open the oil pan flange and check whether it is distorted and flatten it if so. Put on a new gasket on the pan flange, align the pan and place it over the block, fasten bolts and tighten in sequences, starting with the middle to outward spiral manner. Lastly turn on the engine and look at oil leaks at the lower region of the engine especially at the oil pan.
