Lexus 35106-33040 Pan Sub-Assy, Automatic Transaxle Oil

Before proceeding to the removal of the oil pan the job requires you to take off the cable of the negative terminal of your car battery , engage the parking brake and jack up the rear wheels of your automobile . Lift the front of the vehicle and put it on jack stands securely. On this subassembly, if available, take off the two plastic splash shields located under the engine, drain the engine oil, and thereafter, dismantle the oil filter as well as the oil dipstick. Unbolt the oil pan and ensure that if it is tightly fixed then other thin tools like a screwdriver and putty knife can be used to pry off the oil pan without compromising on the mating surfaces in a way that they will develop leaks. For installation, scrape out all the existing sealer from the block and oil pan with a scraper and wipe the mating surface with brake system cleaner. Make sure that the holes on the block for the threaded bolts are smooth and the oil pan flange will not have any warp; if there is, the sharp edges should be smoothened. Check the oil pump pick-up tube assembly on the shop floor for cracks and a blocked strainer and if removed, clean it before re-installation using a new gasket, and tighten the pick-up tube nuts and bolts as specified. Squash an RTV sealant with approximately 3/16-inch thickness on the joining surface of the oil pan, adhere to the producer's instructions for assembling and setting times. Set the oil pan onto the engine block and put the bolts in, just loosely, and then tighten them to the middle from the outside. The rest of the installation process goes in the reverse order to the removal process; however, oil should not be introduced for at least an hour to allow the sealant to harden. Last but not the least, start the engine and observe the oil pressure and any kind leaks.

The first step is to drain the engine oil.

Disconnect the cable from the negative terminal of the battery.
