• Q: How to replace the camshaft on 2007 GMC Canyon?

  A: You can begin Camshaft replacement by taking out the Camshaft cover together with the Camshaft position (CMP) sensor. Reverse Crankshaft rotation until the #1 Piston reaches its top dead center (TDC) position on the compression stroke. The delphi word on the exhaust Camshaft position actuator needs to become parallel to the cam cover mating surface of the Cylinder Head. You should install the Camshaft holding tool (J 44221) behind the camshafts before discarding both intake and exhaust Camshaft sprocket bolts. The installation of the Camshaft sprocket holding tool (J 44222) to the Cylinder Head front requires complete tightening of its two bolts while proper adjustment of the horizontal bolt into the exhaust Camshaft phaser actuator sprocket before sprocket removal from camshafts. Adjust the horizontal bolts into the Camshaft sprockets that are attached to the j 44222 tool which functions as a Cylinder Head sprocket holder to sustain chain tension. Transfer the sprocket with Timing Chain from each Camshaft to the Camshaft sprocket holding tool (J 44222). The mechanic should loosen the Camshaft cap bolts slightly to clear valve spring pressure before removing both caps and the Camshaft holding tool (J 44221) along with the camshafts from the Cylinder Head. Clean engine oil should be applied to the Camshaft journals thrust face and lobes before mounting the Camshaft holding tool (J 44221) with Camshaft flat positioned up against the #1 tdc position. After oiling the intake and exhaust camshafts plus their caps reconstruct them within the original positions by using the marks on the caps as alignment guidance. Put the Camshaft caps in place following their identification marks while tightening all Camshaft cap bolts equally to 12 n.m (106 lb in). A 25 mm (1 in) wrench applied to the hex of the camshafts allows you to steadily rotate them for alignment pin insertion. Remove the Camshaft sprocket holding tool (J 44222) after sliding the sprockets with Timing Chain to the camshafts. Use the angle meter (J 45059) to tighten the intake Camshaft sprocket bolt to 20 n.m (15 lb ft) and an extra measurement of 100 degrees while tightening the exhaust Camshaft actuator bolt to 25 n.m (18 lb ft) with an additional 135 degrees. Reinstall the Camshaft cover after installing the cmp sensor while taking out the Camshaft holding tool (J 44221).
