• Q: How to replace the harmonic balancer on 2007 Cadillac Escalade?

  A: The replacement of a crankshaft balancer requires users to begin by removing the air conditioning Drive Belt alongside cooling fan components along with shroud and Starter motor elements. Use the Flywheel holding tool (J 42386-A) by ensuring its teeth fit the engine Flywheel teeth before mounting it with one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt to a torque of 50 n.m (37 lb ft). The next step involves removing crankshaft balancer bolt (139) because it must be reused when reinstalling the device. Apply both crankshaft balancer remover (J 41816) and crankshaft end protector (J 41816-2) to the crankshaft balancer before using them to take off the balancer (138). The installation requires placing the balancer onto the crankshaft followed by utilization of the crankshaft balancer and sprocket installer (J 41665) with its threaded rod function from the crankshaft front oil seal installer (J 41478) to install the balancer. Tighten the previously used crankshaft balancer bolt to 330 n.m (240 lb ft) in the first stage of tightening before removing it. Check the crankshaft nose depth in the balancer bore using the mentioned dimensions; continue installation until the specified mark is achieved. The new crankshaft balancer bolt (139) requires installation according to a tightening sequence of 50 n.m (37 lb ft) then 140 degrees using the angle meter (J 45059). After removing the Flywheel holding tool (J 42386-A) and bolts you can install the Starter motor and cooling fan along with their associated shroud and a/c Drive Belt followed by completion of the crankshaft position (CKP) system variation learn procedure.
