  Q: How to replace the oil pan on Buick Terraza?

  A: Replacement of an Oil Pan begins with disconnecting the negative Battery Cable before installing the engine support fixture. After vehicle support lift the vehicle and empty the crankcase fluid. Insert the following sequence of steps to begin pan replacement: remove the right front tire and wheel after you perform splash shield removal on that same side. Begin by disconnecting the wheel speed sensor harness at the right suspension support. Then disconnect the right front Ball Joint, bolt, and nut to split the Ball Joint from the Steering Knuckle. Start by removing the lower closeout panel along with A/C Compressor bolts before setting the compressor to the side. To proceed begin by removing braces that support the engine toward the transmission and Starter then disconnect the oil level sensor. First disconnect the retainers that secure the Brake Line to the frame and remove right Engine Mount nuts and bolts. Afterward loosen left cradle bolts and take out frame bolts from the right front and rear locations. First remove the Oil Pan side bolts and Oil Pan bolts then remove the Oil Pan alongside its gasket. Clean all flange surfaces on the Oil Pan as well as the Oil Pan rail and front cover and rear main bearing cap and threaded holes. The installation requires placing a new gasket with gm p/n 1052080 (Canadian P/N 10953480) or equivalent sealant on the Oil Pan gasket tabs when installing the rear main bearing cap. Fasten the Oil Pan bolts to 25 nm (18 ft. Lbs.) while the Oil Pan side bolts require 50 nm (37 ft. Lbs.). Start by replacing the Starter then install the flywheel inspection cover and A/C Compressor onto the engine. Begin installing frame bolts on the right side while adding Engine Mount bolts and nuts and Steering Knuckle Ball Joint on to the right side. Install the right front antilock brake system (ABS) wheel speed sensor harness then install retainers for the Brake Line and engine-to-transmission braces. Secure the right front splash shield together with the tire and wheel assembly and then the lower closeout panel. Lower the vehicle before removing the engine support fixture then fill the crankcase with engine oil before reconnecting the negative cable.
