First obtain these essential tools to change the engine front cover: the front cover oil seal installer carries the j 42851 part number. Front cover oil seal installer (J 42851). Start by disconnecting and removing the
Water Pump then disconnect the camshaft position (CMP) sensor electrical connector before removing engine harness clips from the battery cable channel. The next step requires removal of the cmp sensor bolt then the cmp sensor followed by unbolting the battery cable channel and repositioning the channel. Remove the engine front cover bolts next while keeping the reusable engine front cover gasket in mind before removing it altogether. We need to remove two items from the front cover: first the front cover gasket and second the Crankshaft front oil seal. To install the Crankshaft front oil seal you must use the front cover oil seal installer (J 42851) together with fresh engine oil for lubricating the sealing surface. Use gm p/n 12346286 sealant (Canadian P/N 10953472) in two locations on the engine block where the front cover touches the
Oil Pan. Start by placing the engine front cover gasket into the front cover. Put the front cover on top of the Crankshaft so it rests on the sealant. When installing the engine front cover bolts use a sequence that requires initial torque to 6 nm (53 inch lbs.) followed by torque to 12 nm (106 inch lbs.). Position the battery cable channel into place before securing the cable channel bolt at 9 nm torque (80 inch lbs. Torque). Check the cmp sensor o-ring for damages before applying a minimal layer of clean engine oil to it. Install the sensor with its bolt maintaining a torque of 12 nm (106 inch lbs.). Afterward install the engine harness clips then connect the cmp sensor electrical connector before reinstalling the Crankshaft balancer with the Water Pump.
