Oil Pan

To demolish the Oil Pan, have the required tools: engine support adapters (J 28467-9OA), universal engine support fixture (J 28467-B), engine support adapter leg set (J 36462-A). Start by disconnecting negatively cable from the battery and remove fuel injector sight shield. Then, disconnect the intake air temperature (IAT) sensor electric connector, and take off air inlet duct from the Throttle Body and Drive Belt. Then, after the removal of the right and left engine mount struts, install the engine support fixture and raise the vehicle. Ditch the right exhaust manifold pipe studs nuts from the Catalytic Converter, right front tire and wheel, right side engine splash shield retainers and splash shield. Drain out the engine oil and take out the Oil Filter, remove the A/C Compressor nuts and the A/C Compressor without releasing the a/c system and reposition it later on. Unscrew the guide bracket A/C Compressor bolts, the power steering oil cooler pipes brackets from the frame and disconnect the oil level sensor electrical connection. Remove the oil level sensor wiring sanitary bolt and make way for the wire harness, then unstability the engine mount downpan nuts. Lower the vehicle and lift the engine using the engine support fixture and bring it up before raising the vehicle once more to take off the left and right engine mount bracket bolts. Support the frame with jackstands and loosen the left side frame bolts along with removing the right side frame bolts and bring the right side frame for engine mount bracket removal. Take out the engine mount bracket and torque converter cover and then take out the oil level sensor before you drive in the Oil Pan bolts and place out the Oil Pan. Take off the oil pump pipe as well as the screen-assembled oil pump and Oil Pan Gasket, and clean the Oil Pan flanges along with the Oil Pan rail, front cover and rear main bearing cap, and the threaded holes. The Oil Pan Gasket is to be installed along with the oil pump pipe, and screen assembly and secured by oil pump pipe and screen bolts that are tightened to 15 nm (11 ft. Lbs.). Install the Oil Pan, clean the Oil Pan bolts, and apply one drop of thread lock compound gm p/n 12345382 or equivalent on threads. Tighten the Oil Pan bolts to 14 nm (125 inch lbs) and install the oil level sensor and tighten to 20 nm (15 ft. Lbs). Mount the torque converter cover, engine mount bracket, and loosely mount the right and left engine mount bracket bolts and tighten it to 102 nm (75 lb. Ft.). By means of the jacks, raise the frame to a previous position, and fasten the right side frame bolts, tightening the latter ones, both on the right and left sides, to 180 nm (133 ft. Lbs.). Take off the jackstands and bring the vehicle down, and then use the engine support fixture to bring down the engine. Jack up the vehicle once more to put in the engine mount lower nuts tightening them to 78 nm (58 ft. Lbs.). Mount the oil level sensor wiring harness and the bolt and tighten the bolt to 10 nm (89 inch lbs) and then attach the oil level sensor electrical connector. Mount the power steering oil cooler pipe brackets, a/c compressor bracket, and bolts, tightening the screw brackets on the A/C Compressor bracket to 50 nm (37 ft. Lbs.)) and the A/C Compressor nuts to 30 nm (22 ft. Lbs.)). Change a new Oil Filter, tighten the Oil Pan drain plug to 30 nm (22 ft. Lbs.), right side engine splash shield, and retainers, right front tire and wheel, and right exhaust manifold pipe stud nut also, tighten it to 32 nm (24 ft. Lbs.). Lower the vehicle and remove its engine support fixture, then put right and left engine mount struts, the Drive Belt, and the air inlet duct to the Throttle Body. Hook up the intake air temperature (IAT) sensor, electric connection, fill the crankcase with engine oil, install the fuel injector sight shield, and finish the process, with the negative Battery Cable, checking for leakage during the process.

Start the Oil Pan replacement by disconnecting the negative Battery Cable then removing the fuel injector sight shield followed by disconnecting the intake air temperature (IAT) sensor electrical connector. The process starts with removing the Throttle Body air inlet duct in addition to the right and left Engine Mount struts. Set up the engine support fixture (J 28467-B) before lifting the vehicle with it. Start by removing the right exhaust manifold pipe stud nuts from the Catalytic Converter then drain all engine oil before you remove the Oil Filter. To reposition the wiring harness you need to detach power steering oil cooler pipe brackets from the frame and disconnect oil level sensor electrical connector and remove the oil level sensor wiring harness bolt. Start by removing the lower nuts from the engine mounts then lower the vehicle. The engine support fixture (J 28467-B) helps raise the engine before a second vehicle lift allows workers to remove the left and right Engine Mount bracket bolts, the right stabilizer link, and the right Ball Joint from the Steering Knuckle. Stop the frame with jack stands while you remove the right side frame bolts and loosen the left side frame bolts five turns prior to the frame lowering process. Extract first the Engine Mount and bracket from the frame before removing the torque converter covers. The first step before removing the Oil Pan is to disconnect the oil level sensor because damage is likely to occur. Begin the installation by removing both the Oil Pan bolts then the Oil Pan and the oil pump pipe screen assembly and the Oil Pan Gasket. All mating surfaces of the oil pump screen need cleaning along with the Oil Pan flanges and engine front cover and rear main bearing cap and threaded holes and Oil Pan rail. Place the Oil Pan Gasket and the oil pump pipe screen assembly on the vehicle before tightening the screen bolts to 15 nm (11 ft. Lbs.). We should install the Oil Pan using one drop of thread lock compound gm p/n 12345382 or equivalent on the cleaned Oil Pan bolts before tightening them at 14 nm (125 inch lbs.). After tightening the oil level sensor to 20 nm (15 ft. Lbs.), install the torque converter covers and secure the Engine Mount to the frame. After positioning the frame back to normal height, replace the frame bolts while the jack stands remain in place before removing them. Mount the right Ball Joint onto the Steering Knuckle along with the right stabilizer link before attaching the loose right and left Engine Mount bracket bolts to the engine. Secure these bolts at 102 nm (75 ft. Lbs.). Use the engine support fixture (J 28467-B) to lower the engine after lowering the vehicle. Lift the vehicle for a second time to bolt the Engine Mount lower nuts at 78 nm (58 ft. Lbs.) torque setting before installing the oil level sensor wiring harness and bolt with 10 nm (89 inch lbs.) torque. Next install the power steering oil cooler pipe brackets, right exhaust manifold pipe stud nuts, and connect the oil level sensor electrical connector. Tighten the attachments at 32 nm (24 ft. Lbs.). Place the engine Oil Filter then lower the vehicle and use j 28467-b to remove the engine support fixture after reinstalling the right and left Engine Mount struts. To complete the procedure install the air inlet duct then reconnect the iat sensor electrical connector before filling the crankcase with engine oil while reinstalling the fuel injector sight shield and connecting the negative Battery Cable and performing leak checks and wheel alignment measurements.

Remove the oil pump pipe screen assembly and the oil pan gasket.

Reinstall the right engine splash shield, the right front tire and wheel, and connect the three-way catalytic converter pipe to the right exhaust manifold.

It is used to raise the vehicle.

Lower the vehicle and use the engine support fixture (J35368-B) to lower the engine to its original position.

Disconnect the oil level sensor wiring harness, remove the starter motor, and take off the transaxle brace from the oil pan.

Remove the torque converter covers and the oil level sensor.

Install the starter motor and connect the oil level sensor electrical connector.

Position the engine mount bracket and engine mount, then install the engine mount bracket bolts.

Disconnect the negative battery cable.

Use the Engine Support Fixture (J28467-360) to raise the engine again.
