    Q:
    How to replace the lower timing chain guide on Chevrolet Colorado? Posted by Customer
    A:
    The first step for replacing the lower Timing Chain Guide requires removal of the Timing Chain tensioner shoe. You should slide the crankshaft sprocket off its snout to generate Timing Chain slack that enables the lower Timing Chain Guide removal. Users must extract the lower Timing Chain Guide starting with removal of the cylinder head access hole plug then followed by unscrewing the lower Timing Chain Guide bolts before removing the lower Timing Chain Guide from the engine. The proper installation of the lower Timing Chain Guide requires fitting it to the engine and screwing lower Timing Chain Guide bolts to 12 nm (107 lb in). You should proceed to install the cylinder head access hole plug before torqueing it to 5 nm (44 lb in). Install the crankshaft sprocket onto its snout while positioning the marked chain link straight with the crankshaft timing mark. Position the last component by installing the Timing Chain tensioner shoe.

    Q:
    How to Service and Repair the Timing Chain Guide on Chevrolet Colorado? Posted by Customer
    A:
    Start by taking off the Timing Chain tensioner shoe followed by sliding the crankshaft sprocket from the crankshaft sprocket snout to generate Timing Chain slack that enables lower Timing Chain Guide removal. The first stage involves removing both the lower Timing Chain Guide bolts and cylinder head access hole plug after which the lower Timing Chain Guide can be extracted from the engine. Position the lower Timing Chain Guide to its proper engine location and fasten the lower Timing Chain Guide bolts to 18 n.m (13 lb ft). Replace the cylinder head access hole plug by securing it to 5 n.m (44 lb in) torque before restoring the crankshaft sprocket onto the crankshaft sprocket snout with attention to the marked link facing the timing mark on the crankshaft sprocket. Put back the Timing Chain tensioner shoe as the last step.
