How to service the auxiliary water pump on 2008 Mercury Mariner?

The procedure to service an auxiliary coolant flow pump starts by hoisting the vehicle in NEUTRAL position while draining engine coolant. Start by taking away the LH lower engine splash shield and untie the clamp to unplugged the thermostat hose linking the auxiliary coolant pump with the heater outlet hose. To disconnect the electrical connector of the auxiliary coolant flow pump you must first remove the two securing bolts, re-install these bolts with a torque of 4 Nm (35 lb-in). The process requires removal of the auxiliary coolant flow pump with its rubber bracket assembly before lubricating connected hoses with plain water that should not contain soap or detergent substances. Turn your efforts to reinstall the pump before you complete filling up the engine cooling system.
