GM 12601240
Oil Pan, Green Line

Start by elevating and stabilizing your vehicle before you insert a drain pan under the Drain Plug of the Oil Pan to extract engine oil. Begin by uninstalling the Drive Belt from the engine and the lower ac compressor bolt and then unfasten all Oil Pan bolts. Clean out the old Oil Pan sealant from the surface before you remove the pan. Begin the installation process by clearing both the Oil Pan and lower crankcase sealing surface from oil debris before applying gm pn 12346286 (Canadian PN 10953472) sealant into a 2 mm bead around the Oil Pan edges and oil suction port. Do not exceed recommended application amount. Screw the Oil Pan in place and tighten its bolts starting from the specified sequence to 25 nm (18 ft. Lbs.). To complete the installation you must replace the lower ac compressor bolt then reattach the engine Drive Belt and bring down the vehicle before adding correct oil volume.

To replace the Oil Pan, firstly take off the oil amount indicator and tube, and then lift and support the vehicle. Position a drain pan under the Drain Plug of the engine oil and pull the plug to drain off the engine oil while making sure to reattach and secure the Drain Plug to 25 n.m (18 lb ft) afterward. Then after take off remove, the engine Drive Belt, and remove the lower air conditioning (A/C) compressor bolt. Where a manual transaxle is fitted, one is to remove the 2 lower transaxle bolts; for those with automatic transaxle, take off the 4 lower transaxle bolts. Continue removing Oil Pan bolts and the Oil Pan while at the same time disposing the old Oil Pan sealant. For installation, ensure the Oil Pan and the sealing surface provided on the lower crankcase have gone off oil and dirt. Clean all surfaces that gasket sealing o-rings make contact with. Use a 2 mm line of sealant around the Oil Pan's perimeter and the oil suction port opening but do not apply too much. Mount the Oil Pan and Oil Pan bolts, tightening them to 25 n.m (18 lb ft). Tighten them in the specified sequence. Reinstall 4 lower transaxle bolts (automatrics) or the 2 lower transaxle bolts (manuals), tightening to 75 n.m (55 lb ft) if applicable. Replace the lower a/c compressor bolt and tighten it to 20 n.m (15 lb ft); install the engine Drive Belt; lower the vehicle; and replace the oil level indicator and tube and fill engine oil to the correct level.

Starting with Drive Belt removal you should also remove the oil level indicator tube. Begin by supporting the vehicle from above along with bolting compressor a/c (Air Conditioning) at its top before removing the bottom compressor a/c bolt. The power brake booster pump must have its lower two bolts removed so you can relocate the pump out from the Oil Pan. Drain the engine oil into a suitable pan by first removing the Drain Plug from the Oil Pan then reinstalling the Drain Plug tightly. Use a socket wrench to remove the 4 bolts that connect the Oil Pan to transaxle and then proceed with removing the Oil Pan bolts until the Oil Pan can be removed while simultaneously scraping off any old sealant present in the area. Establish a clean condition for both the Oil Pan and the lower crankcase sealing surface before mounting the parts. Apply a 2 mm bead of sealant to run along the outer edge of the Oil Pan and the oil suction port opening while being careful not to go overboard. Fasten the Oil Pan and its bolts while following the recommended fastener installation steps. Use a torque wrench to tighten the transaxle bolts that hold the Oil Pan at 75 nm (55 lb ft) before moving on to a specified bolt sequence with a torque setting of 25 nm (18 lb ft). Fasten the m8 power brake booster pump bolt with 22 nm (16 lb ft) torque and the m10 bolt with 50 nm (37 lb ft). Lower the vehicle while you firmly tighten the A/C Compressor bolts to 20 nm (15 lb ft). Next, add the oil level indicator tube. You need to put on the Drive Belt then establish the proper engine oil level.

Use the 8 mm guides from the (EN-46109) set in the center oil pan rail bolt hole on each side of the engine block.

Install the 4 oil pan to transaxle bolts and tighten to 75 Nm (55 lb ft).

The oil pan and the sealing surface on the lower crankcase should be free of oil and debris.

Place a drain pan under the oil pan drain plug and remove the drain plug to drain the engine oil.

Clean any old oil pan sealant from the surface.

Lower the vehicle and repeat the previous steps until it can be removed.

Remove the engine mount and raise the engine approximately 76 mm (3 in) using the engine support fixture.

Raise and support the vehicle, then drain the engine oil.

Remove the engine drive belt and the lower AC compressor bolt.
