• Q: How to Service and Repair a Timing Chain for Left on 2004 Cadillac DeVille?

  A: Service and repair operations for the Timing Chain start by disassembling the right secondary camshaft drive chain and both the left secondary drive chain tensioner and left camshaft cover. The camshaft sprocket drive pins must be positioned at their highest rotation point. Users should exercise special caution when using the camshaft holding tool. Put the j 44212 camshaft holding tool (J 44212) across the camshafts prior to taking out left intake camshaft sprocket bolt while using an open end wrench to block camshaft rotation. To begin, unscrew the left intake camshaft sprocket bolt then pull the camshaft sprocket off the shaft and separate the left secondary chain from camshaft teeth. Lift the left secondary camshaft drive chain up from the camshaft intermediate drive shaft sprocket teeth before removing it from the engine compartment. All camshaft timing drive components need thorough cleaning before visual component inspection. When installing the drive chain start by passing the left secondary camshaft drive chain through the left Cylinder Head and onto the left exhaust camshaft sprocket and around the inner tooth row of the camshaft intermediate drive shaft sprocket. Set the left intake camshaft sprocket into position by placing it through left secondary camshaft drive chain and camshaft. Verify that the li notch on the sprocket lines up with the intake camshaft pin. Use an open end wrench to position on the hex cast of the camshaft to stop rotation and torque the left intake camshaft sprocket bolt to 120 nm (89 ft. Lbs.). After removing the j 44212 camshaft holding tool (J 44212) install the left camshaft cover, then proceed with installing the left secondary drive chain tensioner and complete the installation sequence by adding the right secondary camshaft drive chain.
