2006 Mercury Grand Marquis Water Pump Parts Questions & Experts Answers

• Q: How to Service and Repair the Water Pump on 2006 Mercury Grand Marquis?

  A: A repair or service procedure of the coolant pump starts with disengaging the fire suppression system when present before draining the cooling system. First tighten the four bolts that secure the coolant pump pulley then detach the accessory drive belt. Start by removing four bolts which secure the coolant pump pulley followed by four bolts taking hold of the coolant pump assembly while discarding the O-ring seal. The installation requires tightening the bolts to 25 Nm (18 ft. lbs.) while installing the new O-ring seal that should use clean engine coolant. Protect the seal by avoiding any rotation of the pump housing. After the procedure you should reverse all the steps of removal and enable power to the fire suppression system if it exists. To finalize the procedure you must perform a cooling system fill and bleed operation.
