Setting Camshaft Timing

Tools Required

J 39946 Crankshaft Socket. See Special Tools .

Setting the camshaft timing is necessary whenever the camshaft drive system has been disturbed such that the alignment relationship between any chain and sprocket has been lost.

The crankshaft and camshafts are correctly timed when the crank sprocket and the intermediate shaft sprocket have their timing marks aligned and all 4 camshaft position actuator timing marks are perpendicular (90 degrees) to the cylinder head deck surface at the top of their rotation. The black timing chain links are used for assembly purposes. Do not reference these black links to determine if the engine timing components are properly aligned. The black links will only align with the actuator timing marks and the intermediate shaft sprocket, once every 126 revolutions. For this reason, it is not necessary to have the black secondary chain links aligned with the timing marks when servicing only one of the secondary timing components. Proper alignment is maintained by marking a chain link and sprocket gear tooth with a paint stick prior to disassembling individual components. When servicing individual components, refer to the appropriate procedure.

  1. Remove the following components for access to the timing chains: The left camshaft actuator housing-Refer to «Camshaft Position Actuator Housing Replacement - Left Side»(/cadillac/xlr/i-2003-2009/remont/mechanical/#engine-mechanical-44l-1-of-5) .

The engine oil pump-Refer to «Oil Pump Replacement»(/cadillac/xlr/i-2003-2009/remont/mechanical/#engine-mechanical-44l-1-of-5) . The right secondary camshaft drive chain-Refer to «Secondary Camshaft Drive Chain Replacement - Right Side»(/cadillac/xlr/i-2003-2009/remont/mechanical/#engine-mechanical-44l-1-of-5__secondary-camshaft-drive-chain-replacement) .
