  Q: How to replace the oil pan on Chevrolet Suburban 1500?

  A: The procedure starts with disconnecting the negative Battery Cable when replacing the Oil Pan. A front Differential removal becomes necessary for cars equipped with four-wheel drive systems. Initial steps require the removal of the underbody shield combined with its matching Oil Pan shield then proceed to the cross brace according to installation requirements. First drain all engine oil then remove the engine Oil Filter. First disconnect the negative Battery Cable before removing the lower transmission-to-Oil Pan bolts and separating the oil level sensor electrical connector and removing the two front wiring harness retainer bolts and engine wiring harness retainer bolts from the engine Oil Pan. Clear the engine oil cooler pipe to Oil Pan bolt and the transmission oil cooler pipe retainer and bolt from the Oil Pan. Start by removing the Starter motor and left closeout cover bolt and emission control canister. Following this, take out the engine Oil Pan. While building your new assembly place a 5 mm (0.20 inch) bead of gm p/n 12378190 or equivalent sealant on the engine block and both front and rear cover gasket tabs that extend into the Oil Pan surface. Apply gm's p/n 12378190 or equivalent sealant to the engine block and Oil Pan tabs. Then assemble the gasket to the pan before mounting it to the engine block by hand-tightening the bolts until they reach their recommended torque specifications. Next secure the two lower bellhousing bolts with just enough force to place the Oil Pan in its proper position. Tighten all Oil Pan-to-block bolts to 25 n.m (18 lb ft). Use 25 n.m (18 lb ft) torque on the Oil Pan-to-Oil Pan front cover bolts while tightening the Oil Pan-to-rear cover bolts to 12 n.m (106 lb in). Complete the process by tightening the bellhousing bolts to 50 n.m (37 lb ft). Install the left closeout cover along with its bolt through proper torque application to 9 n.m (80 lb in) resistance. Afterward install the Starter motor followed by the transmission oil cooler pipe retainer and its bolt to the Oil Pan before installing the engine oil cooler pipe to Oil Pan bolt after which tighten the engine oil cooler pipe nut to 10 n.m (89 lb in). Fasten the engine wiring harness retainer bolts to the engine Oil Pan then connect the oil level sensor electrical connector and install and tighten the transmission to Oil Pan bolts at 55 n.m (41 lb ft). A four-wheel drive configuration requires reinstalling the front Differential before reinstalling the underbody shield on the vehicle. Lower the vehicle and fill the engine with oil then install the engine Oil Filter before reconnecting the battery's negative cable.
