Oil Pan

Begin by installing an engine support fixture then lift your vehicle into position. The lower AC compressor bolts need removal along with the upper AC compressor bolts and left side frame bolts before extracting the right side frame bolts. Drain the engine oil first. The bolts that secure the oil pan need removal before the oil pan can be extracted from the vehicle. Clean both the mounting surface on the lower crankcase and the oil pan until they remain free of debris and oil residue. Put a 2 mm bead of RTV (GM P/N United States 12346286, GM P/N Canada 10953472) around the oil pan edges and suction port opening while taking care not to apply too much material. Place the oil pan into position before applying torque on all bolts according to their specified notice. Torque the oil pan fasteners until they achieve 25 Nm (18 ft. lbs.). Next tighten the frame bolts on both sides before installing the AC compressor hardware. After lowering the vehicle users should remove the engine support fixture and add the correct amount of engine oil.

The start of Oil Pan replacement begins with vehicle elevation and removal of right front tire and wheel assembly followed by right engine splash shield removal. Empty the engine oil from your vehicle before disassembling the Starter which you will place somewhere safe. First remove the engine mount strut bracket while following it with the Oil Pan bolts and nuts before finally taking off the Oil Pan. Clear and clean all sealing surfaces from the pan as well as the cylinder case and front cover while removing all old rtv residue from the blind attaching holes. To install the Oil Pan use a 2-mm diameter bead of gm p/n 12346286 (Canadian P/N 10953472) 23 loctite 5900 or equivalent on the Oil Pan sealing surface while avoiding the rear seal mounting surface. Apply gm p/n 12346286 (Canadian P/N 10953472) loctite 5900 or equivalent to the Oil Pan sealing surface of the ends down to the ears before installing the new Oil Pan rear seal. Before finalizing installation, tighten first the Oil Pan bolts to 10 nm (89 inch lbs.) then proceed to tighten the Oil Pan nuts to 10 nm (89 inch lbs.). Install all of the following parts starting from the engine mount strut bracket then the Starter and right engine splash shield and right front tire and wheel assembly. Place the vehicle in its lowest position before adding engine oil to the crankcase.

Reinstall the engine splash shield, lower the vehicle, and fill the engine oil to the proper level.

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

Reinstall the AC compressor bolts and the engine mount strut bracket.

Ensure the oil pan and the mounting surface on the lower crankcase are clean and free of oil and debris.
