• Q: How to replace the engine front timing cover on 2006 Chevrolet Avalanche 2500?

  A: In order to remove the engine front cover, first, disconnect the camshaft position (CMP) sensor electrical connector, and remove the Water Pump and crankshaft balancer. Then, the engine harness clips are to be removed from the battery cable channel and the cmp sensor bolt, and then the cmp sensor is to be removed. Then remove the battery cable-channel bolt and move the battery cable-channel. Unfasten the engine front cover bolts and the engine front cover while keeping in mind that the engine front cover gasket can be reused. Once the crankshaft front oil seal was removed from the front cover, install a new crankshaft front oil seal using the front cover oil seal installer (J 42851) and lubricate its sealing surface with clean engine oil. Use sealant gm p/n 12346286 (Canadian P/N 10953472) or gm equivalent in 2 locations on the engine block at the Oil Pan junction with the front cover. Install the engine front cover gasket in the front cover, in so doing observe the appropriate installation procedure in order to avoid the displacement of sealant. Let the pin, holding front cover, rest on the sealant while placing the front cover over the crankshaft, lifting it as going over the crankshaft o, and placing it on the dowel pin. Install and tighten the engine front cover bolts in the sequence first to 6 nm (53 inch lbs.) then to 12 nm (106 inch lbs.). Reposition battery cable channel, install and tighten the battery cable channel bolt to 9 nm (80 inch lbs.). Check the cmp sensor o-ring for any damage and replace it if needed and then apply a thin coat of clean engine oil to it before installing the cmp sensor and tightening the bolt it to 12 nm (106 inch lbs). At last, install the engine harness clips to the battery cable channel, reconnect to the cmp sensor electrical connection, and reinstall crankshaft balancer and Water Pump.
