  Q: How to replace the engine front timing cover on GMC Envoy?

  A: The replacement procedure for the engine front cover starts by draining the engine coolant then continues with cooling fan and shroud removal followed by the Drive Belt and Water Pump and crankshaft balancer and Power Steering Pump. Engine pan removal requires a vehicle elevation then a return to floor height once all removal is complete. Begin by removing the 7 mm center bolt and then loosen the rest of the engine front cover bolts. The cover alignment pins (J 44219) function through placing two front cover bolts into the jack screw holes while tightening them with uniform torque to detach the front cover from the engine. Use a screwdriver to remove the two front cover and Oil Pump bolts which will later be cleaned and inspected. Apply a 3 mm (0.12 inch) bead of sealer to both the trace grooves on the engine front cover's backside and inside three bolt hole bosses before installation. Align the Oil Pump to the crankshaft sprocket splines and install the front cover, ensuring to tighten the front cover bolts to 10 nm (89 inch lbs.) the final installation step should involve tightening the center bolt. You must first remove the cover alignment pins (J 44219) and complete the installation of the Oil Pan followed by lowering the vehicle to add the Power Steering Pump, crankshaft balancer, water pump, Drive Belt and finally the cooling fan and shroud. Place coolant into the engine to carry out final completion.
