A solid connection between the distributor and the spark plugs ensures your vehicle runs correctly. When a spark plug connector becomes loose or receives damage, the spark plug emits a weak spark. This causes the fuel/air mixture inside the engine combustion chamber to partially ignite, wasting fuel and reducing the amount of power generated by the engine. Tightening the crimp on a loose spark plug connector keeps the spark plug firing normally, increasing the power and fuel economy of your vehicle.

Instructions

1

Apply the vehicle parking brake. Pull the hood release to open the hood.

2

Pull the loose spark plug wire off the spark plug and the distributor cap with your hands.

3

Push the boot covering the spark plug connector back onto the spark plug wire to expose the connector.

4

Place a spark plug crimper around the loosened connector with the far end of the crimper sitting even with the end of the connector closest to the spark plug wire. Set the crimper in the jaws of a bench mounted vise.

5

Turn the handle of the bench mounted vise clockwise to force the jaws of the crimper against the spark plug connector. Turn the handle counterclockwise until the crimper releases from the vise jaws. Remove the crimper from the spark plug wire.

6

Push the boot back over the tightened connector. Attach the spark plug wire onto the spark plug and the connector located on the distributor cap.

You can remove the spark plugs on your 2000 Ford Explorer right from your home garage, saving yourself time and money. You should replace the spark plugs every 100,000 miles. The Ford Explorer gives you easy access to the spark plug wires, making the spark plug change quick. It will take you about a half hour to an hour to finish the job.

Instructions

1

Start with a cooled engine. Pop the hood and find the spark plug wires on either side of the engine.

2

Pull the wires off and turn one of the spark plug wires by the large piece on the end of it. This is called the boot.

3

Put a socket into the socket wrench with an extension and put it over the spark plug and turn it counterclockwise until the plug is free. Brush the debris out of the boot and cylinder well with a wire brush. Spray anti-seize compound inside the boot and on the new spark plug thread.

4

Screw the new plug into the well by hand. Test the spark plug tension with a tension tester tool and make any adjustments necessary with the socket wrench until it meets the requirements delineated in the vehicles owners manual.

5

Put the wire back in place and turn it a half turn to the left. Next, turn it to the right until the wire locks on the spark plug.

6

Repeat steps 2 through 5 for the remainder of the spark plugs.

The 2003 Mazda B2300 was produced at the Twin Cities Assembly Plant, in St. Paul, Minnesota, side by side with the Ford Ranger. The 2003 B2300 came equipped with a 2.3-liter, in-line four-cylinder engine. The ignition system on the 2003 B2300 is a coil ignition type, meaning that all of the spark plugs are controlled by a coil module that meters the spark through each wire to the plugs. The spark plug wires are usually removed when changing the plugs, or in order to replace damaged wires with new ones.

Instructions

1

Open the hood of the B2300 and set the hood prop. Remove the negative battery cable from the battery, using a 3/8-inch drive ratchet and socket.

2

Locate the ignition coil -- the box into which all four spark plug wires are routed from the engine. Follow each plug wire from the coil to the engine by running your hand along each wire; as you do so, remove any wire clips from the wires, using a small flat-head screwdriver. These clips are important for keeping the wires in place, so that they do not short out on anything in the engine compartment.

3

Twist the rubber boot at the engine end of one of the wires, while pulling it up off the spark plug. Trace the wire with your hand back to the ignition coil, and remove only one wire from the ignition coil. Pay close attention to the direction the wire is routed in the engine compartment, as it will have to go back the exact same way.

4

Spread the new wires out over the front of the radiator so that you can see the length of each wire. Match the length of the wire you have removed from the B2300 with one of the new wires.

5

Install the new spark plug wire onto the ignition coil. Route the wire through the engine compartment to the engine. Insert the wire and twist it, while pushing the wire downward onto the engine.

6

Repeat Steps 2 through 5 to complete the wire replacement on the entire engine. Secure all of the spark plug wires with the clips that were previously removed, snapping the clips closed, by hand. Double-check that each wire is securely pushed onto each spark plug, and onto the ignition coil.

7

Install the battery cable back onto the battery and tighten the tie-down nut snug with a ratchet and socket.

Toyota started manufacturing the 4Runner in 1984 and still makes this SUV as of 2010. The oil pan sits at the base of the engine and serves as a reservoir for engine oil as it circulates throughout the valves and crankshaft.

In-Line Four Cylinder Engine

Tighten the oil pan bolts for four-cylinder engines up until 1984 to 4.5 foot-lbs. or 54 inch-lbs. For vehicles made from 1985 on, tighten the bolts to 9 foot-lbs. or 108 inch-lbs.

V6 Engine

Most 4Runners in the United States have a V-6 engine. Tighten this engines oil pan bolts to 4.3 foot-lbs. or 52 inch-lbs.

Removing the 4Runner Oil Pan

Removing the oil pan on a 1979 to 1985 4Runner can prove tricky, as it requires separating the front stabilizer bar, leaf springs, shock absorbers and front driveline, then lowering the front axle assembly to create enough clearance. On later models, you must separate the front differential mounts and lower the axle assembly to create enough clearance.
