Toyota 12101-0P040 Pan Sub-Assy, Oil

The manufacturer recommends removing the engine and transaxle assembly to perform this procedure. To begin, drain the engine oil. Next, remove the bolts and nuts securing Oil Pan No. 2 to the larger cast aluminum oil pan. If it is stuck, tap it loose with a rubber-tipped mallet or carefully cut the sealant with a putty knife and hammer. Remove the oil pump pickup tube/strainer assembly and then the bolts and nuts securing oil pan No. 1 to the engine block. Carefully pry the oil pan loose from the engine block, being cautious to only pry in the designated areas. Remove the O-rings from the bottom of the engine block and, if necessary, the sheet metal baffle plate. For installation, first install the baffle plate if it was removed. Clean the mating surfaces of the block and oil pan and ensure the threaded holes in the block are clean. Install new O-rings on the block and check the flange of the steel oil pan for distortion. Flatten and restore the gasket surface if needed. Inspect and clean the strainer before installing it with a new gasket. Apply RTV sealant to the upper oil pan flange and position the pan onto the block, tightening the fasteners in several steps. Apply RTV sealant to the flange of the No. 2 oil pan, position it on the upper oil pan, and install the bolts. The remainder of the installation is the reverse of removal. Add oil, install a new filter, run the engine, and check for leaks.

Disconnect the cable from the negative battery terminal. Set the parking brake and block the rear wheels. Raise the front of the vehicle and support it securely on jackstands. Remove the two plastic splash shields under the engine, if equipped. Drain the engine oil and remove the oil filter. Remove the oil dipstick. Remove the bolts and detach the oil pan. If it's stuck, pry it loose very carefully with a small screwdriver or putty knife. Don't damage the mating surfaces of the pan and block them, or oil leaks could develop. Use a scraper to remove all traces of old sealant from the block and oil pan. Clean the mating surfaces with brake system cleaner. Make sure the threaded bolt holes in the block are clean. Check the oil pan flange for distortion, particularly around the bolt holes. Remove any nicks or burrs as necessary. Inspect the oil pump pick-up tube thoroughly for cracks and a blocked strainer. If the pickup was removed, clean it thoroughly and install it now, using a new gasket. Tighten the nuts and bolts to the torque. Apply a 3/16-inch-wide bead of RTV sealant to the mating surface of the oil pan. Carefully position the oil pan on the engine block and install the oil pan-to-engine block bolts loosely. Working from the center out, tighten the oil pan-to-engine block bolts to the torque in three or four steps. The remainder of installation is the reverse of removal. Be sure to wait at least one hour before adding oil to allow the sealant to properly cure. Run the engine and check for oil pressure and leaks.

Apply RTV sealant to the appropriate sections of the pan, and carefully position and install both the aluminum and steel oil pan sections, tightening the bolts from the center out. Allow the sealant to set for at least two hours.

Apply RTV sealant to the aluminum pan section, following the grooves that indicate where to apply the bead of sealant inside and outside the bolts.

Clean the mating surfaces of the engine block and aluminum pan section, being careful not to gouge the soft metal, which could lead to leaks.

Remove the two plastic splash shields under the engine, if equipped.
