Remove the negative cable from the battery, remove the Camshaft cover, and lift and block the vehicle. Next, take off the engine front cover and let the vehicle down. Finally, unbolt the Camshaft cover once more and use a 24 mm open-end wrench to turn the Camshaft clockwise to align the no. 1 piston at around 60 degrees before top dead center. Remove the spark plugs to accelerate rotation and the Timing Chain Tensioner, the upper Timing Chain Guide, and hold the camshafts with a 24 mm wrench. Proceed to unfasten the exhaust Camshaft sprocket bolt and sprocket, the Timing Chain Tensioner guide, the Engine Mount, the fixed Timing Chain Guide access plug, and the fixed Timing Chain Guide. Discard the intake Camshaft sprocket bolt and remove the intake Camshaft sprocket then take off the Timing Chain from the top of the cylinder head then remove the crankshaft sprocket, oil nozzle and bolt, balance shaft drive chain tensioner, adjustable balance shaft chain guide, small balance shaft drive chain guide, and upper balance shaft drive chain guide. To make it easier to remove the balance shaft drive chain, ensure all the slack for the chain will be between the crankshaft and water pump sprokets. For installations, begin with the upper balance shaft chain guide and tighten its bolts to 10 nm (89 inch lbs), followed by the small balance shaft chain guide and adjustable balance shaft drive chain guide tighten each of these bolts to 10 nm (89 inch lbs). Twist the tensioner plunger by 90 degrees and squeeze it until a paper clip can be inserted, then install the timing link tensioner and tighten the bolts of the 10 nm (89 inch lbs.). remove the paper clip, install an oil nozzle and bolt confident with 10 nm (89 inch lbs.), and install a crankshaft sprocket with the timing at the 5 o"clock position.

Seal, gm p/n 12345382 (Canadian P/N 10953489), to the Timing Chain Guide bolt access hole plug, and tighten to 90 nm (66 ft. Lbs.). Mount the Engine Mount, check the Timing Chain Tensioner for damage, and measure or take the assembly from end to end and ensure it is in a compressed state of 72 mm (2.83 in). If not, apply steps needed to compress it in j 45027-2 and j 45027-1 . Clean the threaded hole of the Timing Chain Tensioner, install the new Timing Chain Tensioner assembly, and tighten 75 nm (55 ft. Lbs.). Compress the tensioner 2 mm (0.079 in) with an appropriate tool and use a 24 mm wrench to hold the Camshaft and tighten the new Camshaft bolts to 85 nm (63 ft. Lbs.) turned 30 degrees added. Last of all, to install the Camshaft cover, lift the vehicle, install the engine front cover, let the vehicle down and reconnect the negative Battery Cable.
