How to Replace the Water Pump in a Mercury Villager

The water pump is the heart of the Mercury Villager's cooling system, circulating the coolant. If the water pump goes bad, it can seriously affect your vehicle's engine and cause damage. Make sure to change out a faulty water pump in your Mercury Villager to keep the engine operating normally.

Remove the Old Pump

Step 1 - Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.

Step 2 - Disconnect the negative battery cable and the radiator hoses and take out the drive belts and remove the fan shroud.

Step 3 - Use a strap wrench, Part Number 303-D055-(D85L-6000-A), to hold the water pump pulley while you loosen and remove the bolts.

Step 4 - Raise the vehicle and remove the five splash shield bolts on the right inner engine and transmission splash shield. Then remove the inner engine and transmission splash shield.

Step 5 - Take out the four splash shield bolts and the two screws on the right side outer engine and transmission splash shield.

Step 6 - Use the strap wrench and hold the crankshaft pulley so that the bolt on the crankshaft pulley can be removed.

Step 7 - Draw the crankshaft pulley from the front of the crankshaft with a crankshaft damper remover and remove the crankshaft pulley.

Step 8 - Loosen and remove the five lower engine cover bolts and remove the front engine cover.

Take out the six water pump bolts and remove the water pump. Take note of the location of each bolt, as they are various lengths.

Install the New Pump

Step 1 - Clean the bolt threads of all bolts and the mating surfaces of the water pump and engine block.

Step 2 - Apply gasket sealer in a continuous bead about 1/8-inch wide to the water pump and install it to the engine block, tightening the bolts to 12 to 15 foot pounds (16 to 21 Nm).

Step 3 - Install the water pump pulley, tightening the 4 bolts to 12 to 15 foot pounds (16 to 21 Nm) while holding the pulley with the strap wrench.

Step 4 - Replace the engine front cover, tightening the 5 bolts to 27 to 44 inch pounds (3 to 5 Nm).

Step 5 - Reinstall the crankshaft pulley and pulley bolt, tightening the bolt to 90 to 98 foot pounds (123 to 132 Nm) while holding the pulley with the strap wrench.

Step 6 - Put the outer and the inner engine and the transmission splash shields back in their place and reinstall the drive belts.

Step 7 - Reconnect the negative battery cable and refill the cooling system.

Start the car and check for leaks when the engine reaches normal operating temperature.

TIPS: Loud noises coming from the cooling system in your Mercury Villager could be a sign that your water pump needs replacing. A leak in the coolant system may also be an indicator. Disconnecting the negative battery cable may reset the on-board computer system or parts of the computer system, so be aware that you may have to reset certain settings.

THINGS YOU'LL NEED: Drain pan, Wrench set, Strap wrench, Coolant

WARNINGS: Never attempt to drain the radiator when the engine in your Mercury Villager is hot. The steam and the hot coolant within the radiator can cause serious burns. Never leave antifreeze open or in puddles. Cats and dogs are attracted to the ethylene glycol in the antifreeze and if they drink it, it could be fatal.
