  Q: How to replace the water pump (LL8) on Buick Rainier?

  A: First drain coolant before you remove the fan and shroud then the Drive Belt to access the Water Pump (LL8). Install the j 41240 fan clutch remover and installer tool to hold the Water Pump Pulley in position. Thread out bolts of the Water Pump Pulley and take off the j 41240 along with the pulley. Begin by unwinding Water Pump bolts before pulling it out the unit. Check and sanitize the Water Pump before replacing its gasket when needed. Place a fresh Water Pump Gasket before setting the Water Pump in place and fastening it with the bolts. Tighten the bolts to 4 nm on the first pass followed by 10 nm on the last turn. Insert the j 41240 between the pulley and Water Pump to secure the component before screwing the bolts tight to 25 nm (18 ft. Lbs.), then remove the j 41240. Complete the system by putting the Drive Belt back on and setting up the fan and shroud afterward. Add recommended coolant to the system and test it for leaks first.
