• Q: How to replace the timing chain and sprockets on 2003 Cadillac Escalade?

  A: To replace the Timing Chain and sprockets, start by replacing the Oil Pump and rotate the Crankshaft until the timing marks are aligned on Crankshaft and sprockets are camshaft to not turn the Crankshaft assembly when the Timing Chain is removed to avoid damage to piston assemblies or valves. Next, take off the camshaft sprocket bolts, camshaft sprocket and Timing Chain. Make use of the j8433 (Two Jaw Puller), j41816-2 (Crankshaft End Protector), and j41558 (Crankshaft Sprocket Remover) to remove the Crankshaft sprocket, and then remove the Crankshaft sprocket. In case you require it, take out the Crankshaft sprocket key and clean and check the Timing Chain and sprockets. For installation, you take the key into the Crankshaft keyway and tap it into the place until its two ends are situated. Place the Crankshaft sprocket at the front of the Crankshaft and make sure the Crankshaft key and the sprocket keyway are in line, and install them fully to the Crankshaft flange with the j41665 (Crankshaft Balancer and Sprocket Installer). Rotate the Crankshaft sprocket until the alignment mark corresponds to 12:00 position, ensuring that the locating pin around the camshaft sprocket would align with the alignment hole of the latter, as well as the teeth of the sprocket teeth and Timing Chain are correctly engaged. Find the camshaft sprocket alignment mark at the 6 o'clock position and install the camshaft sprocket & Timing Chain with the required adjustment to the camshaft sprocket or crank sprocketbringing into the timing alignment marks. Finally, install camshaft sprocket bolts by tightening it to 35nm (26ft. Lbs.), and install the Oil Pump.
