  Q: How to remove and reinstall the oil pan on Chevrolet Suburban 1500?

  A:

  First off remove the left and right closeout covers and bolts and oil level sensor if needed, then remove the Oil Pan. Next, remove Oil Pan by unscrewing Oil Pan bolts and take Oil Pan out carefully, so that no foreign material enter the oil passes and avoid damaging the sealing surface. If necessary, drill out Oil Pan Gasket retaining rivets and remove the gasket, disposed of with the rivets. In the case that the Oil Pan baffle had been removed, insert it and tighten the baffle bolts to 12 nm (106 lb in). Apply a 5 mm (0.2 in) bead of sealant gm p/n 12378521 (Canadian P/N 88901148) to the engine block on tab portions of front and rear cover gaskets which enter the Oil Pan. Accurate the relinquished kinds of the oil gallery passages with the Oil Pan Gasket afterward pre-assemble the gasket to the pan and impose the Oil Pan, gasket, and bolts to the engine cornerstone, and bolt the bolts with your fingers tight. Use a straight edge to make sure that the rear of the engine block and the Oil Pan are flush before tightening the bolts of the Oil Pan-to-block, Oil Pan-to-front cover, bolts at 25 nm (18 lb ft), and the Oil Pan-to-rear cover bolts at 12 nm (106 lb in). Check the alignment of the Oil Pan and engine block, which needs not more than 0,1 mm (0,004 in) gap. If aligning is off-remove Oil Pan-again repeat the process. Lastly, fix the oil level sensor with the help of a wrench, using torque of 13 nm (115 lb in).
