The engine has a two-part oil pan, where only the upper part of the oil pan needs to be removed when the engine is out of the vehicle, therefore, the instructions below are only all about the removal and installation of the lower oil pan when it is still in the vehicle. Removal of bottom oil pan requires firstly, parking brake and blocking rear wheels followed by lifting the front part of the vehicle and holding it firmly on jackstands. Then, take off the under vehicle splash shield, drain the engine oil, and take off the lower oil pan that has the fasteners in a diagonal order. In case, the oil pan is stuck, tap it with a mallet to loosen. To install, remove all traces of old sealant using a scraper on the top and bottom of the oil pan, clean the mating surfaces with brake system cleaner, and apply a bead of RTV sealant 1/8-inch in height to the oil pan flange and make certain that the oil pan is in place within 5 minutes of sealant application. The lower oil pan goes on the top pan and the bolts are installed and hand-tightened then all bolts should be tightened in a diagonal pattern to the recommended torque, the sealant should be allowed to dry and then oil should be added. Removal is the opposite of installation and then the engine should be started to examine the presence of oil pressure and leaks. As per the upper oil pan, firstly the low-lying oil pan is removed, and then the transaxle, crankshaft front oil seal flange, camshaft sprockets are loosened, control housing, oil pump chain tensioner and guide are removed, the pick-up tube retaining fasteners and the pick-up tube-to-oil pump seal are removed. Once the upper oil pan mounting fastensers have been removed, the oil pan can then be removed, however, by prying it off, but being very careful to pry at the number 6 and number 1 crankshaft bearing caps. To install, repeat above scraper used to clean the old sealant and clean the mating surfaces, apply RTV silicone sealant on the mating surface between the oil pan and the cylinder block. Clean up the threaded bolt holes and test the oil pan flange to be distortion free, meaning eliminate any nicks or burrs. Place the upper oil pan onto the block of the cylinder, fix and tighten two mounting connectors in front and back, and align the ends of the upper pan and the cylinder block. Installation of the oil pan should be done with a special tool till the edges are aligned and then install the rest of the bolts and tighten them in a diagonal pattern. Lastly, fit the oil pick-up tube and new seal, run the mounting fasteners and fit the oil pump timing chain and tensioner and leave the sealant to dry before putting the oil in and reassemble the assembly in reverse sequence of dismantling.
