  Q: How to replace the LH secondary camshaft timing chain on Buick Enclave?

  A:

  To switch out the left Timing Chain, kick things off by taking off the front cover of the engine. Then, remove the right bank Timing Chain Tensioner (Tensioner), then take out the right bank Timing Chain shoe (Shoe), guide (Guide), and chain (Chain). After that, take out the primary Timing Chain Tensioner, the primary upper Timing Chain Guide, and the primary Timing Chain. Afterwards, take off the right bank camshaft intermediate drive chain idler (Idler), the left bank Timing Chain Tensioner (Tensioner), the left bank Timing Chain shoe (Shoe), the left bank Timing Chain Guide (Guide), the left bank cam. Look over and clean all of the camshaft timing drive components, changing any that don't work properly. Start by putting on the left bank Timing Chain (Chain). Then, fit the right bank intermediate drive chain idler (Idler), the primary Timing Chain (Chain), the primary upper Timing Chain Guide (Guide), and the primary tensioner (Tensioner). The last step is to set the right bank Timing Chain (Chain), right bank Timing Chain Guide (Guide), right bank Timing Chain shoe (Shoe), right bank Timing Chain Tensioner (Tensioner), then put the engine front cover back on.
