Disconnect the electrical connector for the fuel sending unit, and remove the mounting nuts for the fuel sending unit. Disconnect the fuel sending unit from the fuel pump.

    4

    Attach the fuel sending unit to the new fuel pump, and fasten the mounting nuts for the fuel sending unit with a socket wrench. Connect the electrical connector for the fuel sending unit, and place a new gasket on the fuel tank. Install the fuel pump assembly into the fuel tank, and fasten the mounting screws for the fuel pump assembly. Attach the fuel lines to the fuel pump assembly.

How to Replace the Water Pump in a 1991 Mazda MPV

The Mazda MPV is a minivan produced by Mazda since 1989. Rear-wheel drive was standard on the 1991 model, but a 4x4 version was also available. The term "4x4" in this context indicates that the vehicle has four wheels that receive power from the drivetrain independently. The water pump in a 1991 Mazda MPV attaches to the front of the engine block and its replacement requires the removal of several additional components.

Instructions

    1

    Start the engine and remove the electrical connector for the fuel pump. Allow the engine to stall and turn the ignition off. Connect the electrical connector for the fuel pump.

    2

    Remove the cable to the negative battery with a socket wrench to prevent the battery from causing sparks. Disconnect the air cleaner assembly.

    3

    Place a sealable container under the radiator drain and open the radiator drain cock. Allow the coolant to drain into the container and replace the drain cock. Seal the container of coolant for later use.

    4

    Disconnect the electrical wires to the spark plugs. Remove the air duct assembly, cooling fan, and cowling for the radiator with a socket wrench. Disconnect the drive belts and the pulley for the air-conditioner idler.

    5

    Disconnect the baffle plate for the crankshaft pulley and remove the pulley with a socket wrench. Detach the coolant bypass hose and the upper hose for the radiator. Remove the retaining bolts for the timing belt cover, and remove the timing belt cover.

    6

    Disconnect the upper idler pulley with a socket wrench and mark the direction of rotation on the timing belt so that you can install it correctly later. Remove the timing belt and the tensioner for the timing belt.

    7

    Disconnect the mounting bolts for the water pump with a socket wrench. Remove the water pump from the engine block and discard the gasket for the water pump. Clean the mating surfaces for the gasket with a clean shop towel. Coat the new gasket with sealer and place it into position. Install the new water pump onto the engine and tighten the mounting bolts to between 14 and 19 ft.-lbs. with a torque wrench.

    8

    Complete the water pump installation by performing steps 2 through 7 in reverse order. Fill the radiator with coolant and connect the air cleaner assembly with a socket wrench. Attach the cable to the negative battery terminal.
