• Q: How to replace the oil pan on 2005 Chevrolet Trailblazer?

  A: You should start by disconnecting the negative Battery Cable when replacing the Oil Pan. Unbolt the A/C Compressor from its bottom position while also loosening its top bolts numbers two and three. Start by extracting the tube along with the oil level indicator before you can remove the stabilizer shaft. First secure the front Differential to the frame as you remove it and afterward extract the front drive axle intermediate shaft bearing assembly. Begin by draining engine oil then working to unfasten transmission cooler lines which are attached to the engine block. Unscrew the 4 bolts securing the bell housing to the Oil Pan before eliminating the other Oil Pan bolts. Tighten the Oil Pan bolts placed in jack screws until the engine releases the Oil Pan. Pause Oil Pan installation while adding a 3 mm (0.12 in) bead of sealer to the engine block's surface. First normalize the space between the Oil Pan and screen assembly then guide the Oil Pan into position and secure it using proper fasteners at their specified locations. Ensure accurate alignment of the Oil Pan using a straight edge across the block's backside and transmission-mounting region before tightening all side bolts to 25 nm (18 lb ft) and end bolts to 10 nm (89 lb in). After securing the transmission bell housing bolts with 47 nm (35 lb ft) torque, return the transmission cooling line installation to the engine block. The maintenance process includes reinstallation of the front drive axle intermediate shaft bearing assembly and oil drain plug and filter preceding installation of the front Differential and stabilizer shaft. Before finishing, torque the bottom A/C Compressor bolts (2, 3, 4) to 50 nm (37 lb ft). Conclude by installing both the oil level indicator and tube then reconnect the negative Battery Cable afterward inspect the engine for oil leaks and perform engine oil filling.
