How to replace the harmonic balancer on Buick Rainier?

The Radiator and Drive Belt must be removed at first step before handling the crankshaft balancer replacement process. The diagonal brace needs just one bolt from the battery tray brace removed for detachment. Start by loosening the balancer bolt before discarding it along with removing the service slot plug to lower the vehicle. Follow the procedure in j 41816-2 and j 41816-a to extract the crankshaft balancer by avoiding any pulling force on the outer edge. Proceed by taking away the puller and j 41816-a then discard the crankshaft balancer shim before cleaning the balancer. After vehicle elevating place a new crankshaft balancer shim (GM P/N 12573950 for 2003 and first design 2004, GM P/N 12578073 for second design 2004 and later) on the crankshaft snout. First install the balancer with en-48034 then remove it with the same tool to secure it with j 44226-1 which prevents turning. Install the new bolt with the balancer washer and follow this by tightening the crankshaft balancer bolt to 150 nm (110 ft. Lbs.) then add another 180° closure using j 45059. The worker removes the torque converter holding device followed by installing the torque converter access plug into the Oil Pan. After lowering the vehicle he returns the Drive Belt and Radiator assembly.
