Lexus 35106-48011 Pan Sub-Assembly, TRANSAXLE

To remove the hood, disconnect the cable from the negative terminal of the battery, raise the vehicle, and securely support it on jackstands. Remove the engine splash shields, drain the engine oil, and remove the oil filter. The oil pan consists of an aluminum casting attached to the block and transaxle, along with a lower stamped-steel pan section. Disconnect the front exhaust pipe from the catalytic converter and the support bracket, and remove the nuts holding the pipe to the exhaust manifolds. Remove the driveplate cover by taking out two bolts, then remove the two bolts securing the aluminum oil pan section to the transaxle. Detach the steel oil pan section by removing ten bolts and two nuts; if it's stuck, carefully pry it loose without damaging the mating surfaces. Remove the oil pump strainer/pickup and the bolts securing the aluminum oil pan section to the block, noting that some bolts may be under the steel pan. If equipped, remove the oil pan baffle plate. For installation, use a scraper to eliminate old sealant from the block and oil pan, clean the mating surfaces, and ensure the threaded bolt holes in the block are clean. Check the flange of the steel pan section for distortion and flatten it if necessary. Reinstall the baffle if it was removed, clean the mating surfaces of the engine block and aluminum pan section, and apply a 4 mm wide bead of RTV sealant to the aluminum pan section. Install the aluminum pan section within five minutes and uniformly tighten the bolts from the center outwards. Inspect the oil pump pick-up/strainer assembly for cracks and blockages, clean it if removed, and install it with a new gasket. Apply a 3 to 4 mm wide bead of RTV sealant to the flange of the steel oil pan section, position it carefully on the aluminum section, and install the bolts, tightening them from the center out. The remainder of the installation follows the reverse order of removal, allowing the sealant to set for at least two hours before adding new oil and a new oil filter, then run the engine to check for oil pressure and leaks.

Apply RTV sealant to the flange of the No. 2 oil pan, position it on the upper oil pan, and install the bolts.

To inspect and install the oil pump pick-up tube:Thoroughly inspect the oil pump pick-up tube for cracks and a blocked strainer.If removed, clean the pick-up tube and install it with a new gasket.Tighten the nuts and bolts to the specified torque.

The remainder of the installation is the reverse of removal. Add oil and install a new filter. Run the engine and check for leaks.
