• Q: How to replace the engine front timing cover on 2005 Cadillac DeVille?

  A: In order to replace the engine front cover, start by removing the drive belt tensioner, after which the drive belt idler pulley bolt and the pulley itself need to be removed. Next, remove the balancer of the crankshaft and raise the vehicle while lifting the engine assembly with an appropriate jack. Solve the nut that holds the Engine Mount to the Engine Mount bracket, and then undo the nut that holds the Power Steering Hose to the Engine Mount bracket. Take out the bolts that hold the Engine Mount bracket to the engine where you can remove the rest of the bolt to locate the engine front cover. Place the Engine Mount bracket down, then loosen and remove the engine front cover bolts and remove the engine front cover and gasket that isn't used again if damaged. For installation, apply a little sealant gm p/n 12345739 (Canada P/N 10953472) to the split line of the upper and lower crankcases, set the engine front cover gasket on the crankcase dowel, and install the engine front cover on the crankcase. Mount the engine front cover retaining bolts and tighten them in the prescribed order down to 10 nm (89 inch lbs.). Replace the crankshaft balancer and the bolts that fix the Engine Mount bracket to the engine, applying the torque of 50 nm (37 ft. Lbs.). Second, install the nut that holds the Power Steering Hose to Engine Mount bracket that is also tightened to 9 nm (80 inch lbs.) and also the nut that secures the Engine Mount on the Engine Mount bracket that needs to be tightened to 80 nm (59 ft. Lbs.). Also remove the engine support jack, lower the vehicle, and install the drive belt idler pulley and its bolt, tightening the bolt to 50 nm (37 ft. Lbs.), and then install the drive belt tensioner.
