Two-links are of matching color, and1-link is of a unique color. Note:There are 3-colored links on the timing chain. The proper mark is also in line with a semicircularnotch in the inner diameter of the gear.Install the inner friction washer-(1).Install the crankshaft sprocket with the timing mark-(2) is in the 5-o'clock positionand facing outward.Install the outer friction washer-(1) if equipped. If applicable, the washer must be removed in order to view the correcttiming mark on the lower crank gear. The outer spacer/washer is in between the crank/balancerpulley and the lower timing gear and may remain in place when the pulley is removed.The spacer/washer has a dot/mark on its surface that may be mistaken for the lowertiming mark. Note:Ecotec 4 cylinder engines with SIDI-Direct Injection, the lower timing chain crankgear may be equipped with a second spacing washer installed in front of the lowertiming chain crank gear. The number-1 piston should be attop dead center (TDC), crankshaft key at 12-o'clock. Note:If equipped with following engine LAP, LE8, LEA, LUK, or 2011 LAF, ensure the intakecamshaft notch is in the 10 o'clock position and the exhaust camshaft notch is inthe 7 o'clock position and beyond.Ensure the intake camshaft notch is in the 10-o'clock position-(2) and the exhaustcamshaft notch is in the 7-o'clock position-(1). Note:If equipped with one the following engine LE5, LE9, LAT, LNF, LDK, LHU, LTD, LBN,or 2010 LAF, ensure the intake camshaft notch is in the 5-o'clock position-and theexhaust camshaft notch is in the 7-o'clock position and beyond.Ensure the intake camshaft notch is in the 5-o'clock position-(2) and the exhaustcamshaft notch is in the 7-o'clock position-(1). The proper mark is also in line with a semicircularnotch in the inner diameter of the gear.Remove the outer friction washer-(1) if equipped.Ensure the crankshaft gear timing mark-(2) is in the 5-o'clock position and crankshaftkey is in the 12-o'clock position.Remove the crankshaft sprocket-(3).Remove the inner friction washer-(1).Installation Procedure Install a 24-mm wrench on the hex on the intake camshaft in order to hold the camshaft.Remove and discard the intake camshaft actuator bolt-(2).Remove the intake camshaft actuator-(3), and the timing chain through the top of thecylinder head. Remove the fixed timing chain guide bolts and guide. Remove the fixed timing chain guide access plug. Remove the timing chain tensioner guide bolt and guide. Install a 24-mm wrench on the hex on the exhaust camshaft in order to hold the camshaft.Remove and discard the exhaust camshaft actuator bolt-(2).Remove the exhaust camshaft actuator-(1,-3) from the camshaft and timing chain. If it is not, the timing chain will become cocked and it will bedifficult to remove.Remove the timing chain tensioner. Note:The timing chain tensioner must be removed to unload chain tension before the timingchain is removed. Refer toEngine Front Cover ReplacementRemove the upper timing chain guide bolts and guide. Refer toSpark Plug Replacement.Rotate the crankshaft in the engine rotational direction clockwise, until the number-1piston is at top dead center (TDC) on the exhaust stroke.Remove the engine front cover. Refer toCamshaft Cover Replacement.Remove the number-1 cylinder spark plug.
