2004 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to service and repair the timing cover on 2004 Cadillac DeVille?

  A: Maintenance operations on the Timing Cover commence with drive belt tensioner elimination followed by drive belt idler pulley bolt and idler pulley removal. Start by removing the crankshaft balancer then raise the vehicle for support. A suitable Engine Mount support allows you to remove the Engine Mount securing nut from both the Engine Mount bracket and Power Steering Hose bracket. First unwedge the Engine Mount bracket bolts which attach the bracket to the engine before softening the last Engine Mount bracket bolt to create access to the engine front cover. Beginning with positioning the Engine Mount bracket aside you should proceed by taking off the engine front cover with its gasket that can be reused unless showing damage. First make an application of gm p/n 12345739 sealant (or Canadian P/N 10953472) to the split line separating upper and lower crankcases. Place the engine front cover gasket over crankcase dowel pins and set the front cover into position on the crankcase unit. Put the engine front cover retaining bolts in position to be tightened using 10 nm (89 in. Lbs.) torque sequence. Secure the crankshaft balancer and Engine Mount bracket bolts to the engine using a torque of 50 nm (37 ft. Lbs.). Second, apply 9 nm (80 in. Lbs.) torque to the Power Steering Hose's nut when fastened to the Engine Mount bracket. The Engine Mount-to-engine mount bracket nut requires 80 nm (59 ft. Lbs.) torque for secure attachment. Lower the vehicle while you install the drive belt idler pulley with its bolt. Secure the bolt using 50 nm (37 ft. Lbs.) torque before you attach the drive belt tensioner.
