  Q: How to replace the LH secondary camshaft timing chain on Cadillac SRX?

  A:

  The first step is to remove the Spark Plugs and the engine front cover in order to rotate the Crankshaft for the entire replacement process. Then, detach the right bank Timing Chain Tensioner, right bank Timing Chain shoe, right bank guide and right bank Timing Chain. Then, take out the primary Timing Chain Tensioner (Tensioner), the primary upper Timing Chain Guide (Guide) and the primary Timing Chain (Chain). Remove the left bank Timing Chain Guide, shoe and tensioner as well as the right bank camshaft intermediate Timing Chain idler. Last step is to take out the left bank Timing Chain and clean and inspect all camshaft timing drive parts, installing new ones if required. Begin installation by inserting the left bank Timing Chain (Chain) and then following it with the left bank camshaft intermediate Timing Chain idler (Idler), left bank Timing Chain Guide (Guide), left bank Timing Chain shoe (Shoe) and left bank Timing Chain Tensioner (Tensioner). After that, place the right bank camshaft intermediate Timing Chain idler (Idler), primary Timing Chain (Chain), primary upper Timing Chain Guide (Guide) and primary Timing Chain Tensioner (Tensioner). Replace the right bank Timing Chain with the guide, shoe and tensioner. Install the spark plugs and the engine front cover as the last step.

  Q: How to replace the Timing Chain on the right side on Cadillac SRX?

  A:

  Replacement of the right-side Timing Chain begins with removing the Oil Pump. With tool j 39946 (J 39946) rotate the Crankshaft until the primary timing gear marks meet up. Keep the actuator solenoids attached when you remove the right Camshaft position actuator housing. Special caution is essential when working with the en 46328 (EN 46328) installed on bank 1 (right) camshafts. Use j 39946 or en 46328 to loosen then remove right Timing Chain Tensioner bolts together with the tensioner. Reverse the Camshaft movement using an open-end wrench during removal of bank 1 (right) exhaust and intake Camshaft position oil control valves. The technicians should first detach the Timing Chain from actuator teeth before removing right exhaust and intake Camshaft position actuators from their Camshaft position. All components of the Camshaft timing drive need clean-up and inspection. Upon installation position all three black links of the Timing Chain in precise alignment with timing marks found on bank 1 exhaust and intake actuators and the intermediate sprocket. Mount the Timing Chain to the intermediate sprocket while maintaining precise alignment. Secure the actuators on their camshafts so their timing marks face directly opposite the cylinder head deck surface. Then loosely install the oil control valves before tightening them to 120 n.m (89 lb ft) as a preventive measure against Camshaft rotation. Installation must start with the right Timing Chain Tensioner followed by en 46328 removal then right Camshaft position actuator housing replacement before finishing with the Oil Pump.
