How to replace the harmonic balancer on GMC Terrain?

The first step for replacing the crankshaft balancer involves Drive Belt removal. The Harmonic Balancer holder (J 38122-A) should be used to stop crankshaft rotation before you remove the crankshaft balancer bolt to discard it with the balancer. The installation process requires placing a new crankshaft balancer while installing a new balancer bolt. The Harmonic Balancer holder (J 38122-A) should maintain position of the balancer while you tighten the bolt. The crankshaft balancer bolt needs to be tightened with an angle meter (J 45059) to 100 nm (74 lb ft) torque and an additional 125 degrees of angle. Finally, reinstall the Drive Belt.
