Repair 7

The Mazda B Series is a line of pickup trucks that Mazda Motor Corporation has manufactured since 1961. The number in the model name indicates the displacement of the engine, so the B2200 has a 2.2-liter engine. This engine has a single overhead camshaft, and uses a timing belt to coordinate the opening and closing of the cylinder valves. The replacement of the timing belt in a 1989 Mazda B2200 is part of its routine maintenance schedule.

Instructions

1

Remove the cable from the negative battery terminal with a socket wrench, and detach the accessory drive belts. Disconnect the covers for the timing belt.

2

Turn the crankshaft clockwise to align the A mark on the camshaft pulley with the timing mark on the camshaft housing. Disconnect the mounting bolts for the crankshaft pulley with a socket wrench, and remove the pulley from the crankshaft.

3

Detach the spring for the timing belt tensioner with a pair of brake pliers. Disconnect the mounting bolt from the timing belt tensioner with a socket wrench and remove the tensioner. Disconnect the timing belt from its pulleys.

4

Place a T-wrench onto one of the housing bolts for the camshaft pulley. Place another T-wrench on the mounting bolt for the pulley and disconnect the mounting bolt. Remove the camshaft pulley from the camshaft.

5

Install the new timing belt and align the timing marks on the camshaft pulley if necessary. Ensure that the timing belt engages the teeth on the sprockets of the camshaft, crankshaft and belt tensioner.

6

Install the mounting bolt for the belt tensioner and tighten it by hand. Install the tensioner spring, and loosen the lock bolt for the belt tensioner with a socket wrench.

7

Turn the crankshaft clockwise by two turns and align the timing marks. Tighten the locking bolt on the timing belt to between 28 and 38 ft. lbs. with a torque wrench. Turn the timing belt tensioner to adjust the tension on the timing belt. The timing belt should deflect by about 12mm when you apply a force of 22 lbs. to the longest span of the timing belt.

8

Replace the covers for the timing belt with a socket wrench, and attach the accessory drive belts. Connect the cable to the negative battery terminal.

The 1997 Mazda Protg has a single oxygen sensor threaded into the exhaust manifold. When the sensor fails, it will trigger the "Check Engine" light on your cars instrument panel, and your cars gas mileage will substantially decrease. If you want to avoid losing money at the gas pump, purchase a new sensor from an auto parts store and replace it at home.

Instructions

1

Raise the Protg with a jack and secure the car on jack stands. Locate the oxygen sensor threaded into the exhaust manifold. The exhaust manifold is located beneath the intake at the base of the engine and is connected to the exhaust pipe. The oxygen sensor resembles a spark plug threaded into the manifold with an electrical wire connected to the top.

2

Pull the electrical connection apart to disconnect the wiring harness from the sensor. Remove the oxygen sensor from the manifold with a wrench.

3

Coat the new sensor threads with anti-seize compound. Insert the new sensor by hand. Tighten the sensor with the wrench. Push the electrical connection together until it locks.

4

Raise the car slightly with the jack. Remove the jack stands and lower the jack to return the car to the ground.

The Mazda 6 sedan is equipped with fixed door mirrors that may be subject to damage from minor car accidents. The procedure for replacing a door mirror is simple enough to be performed at home using basic tools, although it does require partial removal of the interior door panel. You can obtain a replacement mirror at either a Mazda dealer parts counter or you may find one at a local parts shop or junkyard.

Instructions

Removing the door and mirror assemblies

1

Open the hood and disconnect the negative battery cable.

2

Remove the tweeter speaker assembly from the inside of the door where the window frame meets the front of the door. Use a wide, flat bladed screwdriver or your fingers to caully pop the retaining clips around the assembly away from the door.

3

Disconnect the tweeter assembly from the doors wiring by pushing the locking pin down and separating the connector pieces. Set the tweeter assembly aside.

4

Pop off the cover for the door light at the base of the door panel. This is held in place by plastic prongs. Once this is removed, remove the screw located underneath.

5

Pop open the small cap underneath the passenger side door handle and remove the screw hidden below the cap. Pull the door handle out and remove the plastic surrounding piece. Disconnect the wiring for the power door lock and set the plastic surrounding piece aside.

6

In the door handle "pocket," pull the rubbery trim piece up ---this is secured by adhesive--- just enough to access the screw hidden beneath. Remove the screw.

7

Caully work your way around the door panel starting at the base and pull the panel out to the retaining clips holding the panel in place. There are two clips at the back (latching) side, there are two along the base, one at the front lower corner, and three going up the front (hinge) side.

8

Lift the door panel vertically to disengage the hooks from the top of the door. You may be able to just disengage the front hook while leaving the rear hook clipped. Allow the panel to come away from the door structure enough to allow access to the three bolts holding the door mirror in place. This will not require disconnecting the power window harness.

9

Disconnect the power mirror electrical connector and remove the three nuts holding the mirror assembly on the door. Gently work the mirror away from the door.

Installing the mirror and door assemblies

10

Insert the bolts on the replacement mirror assembly through the openings in the door and thread the nuts onto the bolts. Tighten the nuts, ensuring that the fit is snug and even. Reconnect the power mirror wiring harness.

11

Hook the door panel back to the top of the door structure, caully ensuring that the panel lines up properly and that the interior door handle fits through the cutout in the door panel. Work around the door panel pushing each of the retaining clips back into place.

12

Insert the screw into the hole in the door handle pocket ---under the rubbery trim--- and tighten it to snug. Push the trim down and hold until the adhesive sticks it into place.

13

Clip the wiring connector for the power door lock back onto the harness and work the trim piece into place around the interior door handle. Insert the screw into the hole in the trim piece and tighten until snug. Push the cap into place covering the screw. Insert the screw into the hole by the door light and tighten until snug. Clip the door light cover into place.

14

Reconnect the tweeter wiring harness and reinstall it by pushing the retaining clips back into place. Reconnect the cars battery and test to make sure that the electrical connections are properly installed and that all devices work as intended.

You can read the trouble codes on your 93 Mazda 626 right from your home garage, saving your time and money. The On-Board Diagnostics II computer (OBDII) comes standard on the Mazda 626. This computer receives trouble codes from sensors positioned throughout the vehicle that monitor all of the cars functions. When it receives a trouble code, it alerts you by illuminating a warning or service light on the vehicles instrument panel. When you see one of these lights, you can read the codes using an OBDII scanner to pinpoint the problem.

Instructions

1

Put the key into the ignition and turn it to the "II" position. Dont start the engine.

2

Look for an open port on the lower drivers-side dashboard, near the steering column. Plug the scanner into the port. The vehicles electrical system will power on the OBDII scanner. Wait for the codes to appear on the scanner.

3

Write down the codes on a piece of paper and look them up in the booklet that came with the scanner. The numerical codes will be translated into descriptions.

4

Unplug the scanner and turn off the vehicle. Take the codes and descriptions to your mechanic to have your vehicle serviced or repaired.

The Madza RX-7 is a two-seater sports car made by Mazda. The RX-7 is unique in that, unlike almost every other car on the market, the RX-7 uses a rotary engine instead of a piston engine to make its power. This is practically unheard of in the automotive world. The 2-rotor engine, also called a Wankel engine after its inventor, Felix Wankel, has up to 40% fewer parts than a piston engine and is able to create a tremendous amount of power with a lightweight, simple design. With that said, the Mazda RX-7 does have a traditional exhaust system, which includes a catalytic converter. Over time, as in piston engines, these converters eventually burn out and need to be replaced.

Instructions

1

Jack up the front of the RX-7. Place the jack under the front jack point of the RX-7. This is located behind radiator.

2

Place jack stands under the frame of the vehicle and lower the RX-7 onto the jack stands.

3

Unplug the electrical wiring running to the O2 sensor on the catalytic converter.

4

Remove the catalytic converter to exhaust tubing bolts with a socket wrench.

5

Remove the catalytic converter to manifold bolts with a socket wrench.

6

Separate the catalytic converter from both sides of the exhaust. You may need to use a flat head screwdriver to pry the mating surfaces apart.

The Mazda MPV is a four-door sedan designed for fuel efficiency. If your Mazda MPV isnt starting properly, you could have a dead battery or no fuel in the car. A broken fuel gauge can give you the wrong information and allow you to run the car down. A dead battery will not be able to spark the motor and keep the car from starting. You can troubleshoot your Mazda MPV by checking the fuel and the battery.

Instructions

1

Open the hood to the Mazda MPV. Locate the battery; its to the right of the engine.

2

Use a socket wrench to remove the battery terminals. Inspect the battery terminals for any corrosion.

3

Use a wire brush and a can of soda to clean the corrosion off of the terminals. Replace the terminals on the battery and try to start the car.

4

Smell the battery for a rotten egg smell. This is sulfur and means that the battery is dead. Replace the battery if you detect this odor.

5

Use a different car and a pair of jumper cables to jump-start your MPV. Allow the car to sit for about five minutes in order to charge the MPVs battery.

6

Turn the MPV off and then try to start the car. If the car will not start, you need to change the battery.

7

Add a gallon of fuel to the car and then try to start it. Replace the fuel gauge if the car starts up.

You can turn off the check engine light yourself manually on your Mazda. When the light illuminates on the instrument panel, it is telling you that there is a problem with the valves, solenoids or sensors on the Mazda. In any case, its a problem that needs to be looked at immediately by a qualified mechanic. Turning off the light is a very quick and fairly simple process that requires just a couple of basic tools.

Instructions

1

Lift the hood of your vehicle and prop it open. Remove the negative cable from the battery terminal by loosening the nut on the cable with a 10-mm end wrench. (If you have a Miata, the battery is in the trunk.)

2

Wait for five minutes, taking care not to allow the negative battery clamp to touch the positive clamp or the positive side of the battery.

3

Reattach the negative cable to the battery and tighten the nut using the end wrench.

4

Put the key into the ignition and turn it to "On." Look at the instrument panel to make sure the check engine light has turned off.
