2008 GMC Canyon Timing Chain Tensioner Parts and Q&A

• Q: How to replace the timing chain tensioner on 2008 GMC Canyon?

  A: Start by removing the camshaft cover together with the engine front cover before you can replace the Timing Chain tensioner. Rotate the Crankshaft clockwise until the #1 Piston is at top dead center (TDC) on the compression stroke. The j 44221 (Camshaft Holding Tool) which goes at the camshaft rear needs extra attention to safety. Mark the Timing Chain links next to the timing marks which are visible on the exhaust camshaft position actuator sprocket and intake camshaft sprocket and Crankshaft sprocket. Put a tee into the tensioner to hold the shoe in place after moving the tensioner shoe in. Start by detaching the bolts from the Timing Chain tensioner then pull the tensioner assembly out from the engine. Monte carlo mark sets Timing Chain tensioner position on the engine before securing Timing Chain tensioner bolts at 25 n.m torque (18 lb ft). When the tee is removed tension returns to the Timing Chain so j 44221 can be taken off from the camshafts. Position each seventh dark link of the Timing Chain to match the timing indicators which appear on the exhaust camshaft position actuator sprocket, intake camshaft sprocket, and Crankshaft sprocket. Afterward position both the engine front cover and camshaft cover in place.
