Fix It

A timing light uses a strobe flash to determine the ignition timing of a car, which is the frequency of spark plugs firing. The timing light illuminates marks that the car manufacturer has placed on the engines crankshaft pulley or flywheel. The position of the marks when the engine is running indicates the timing of the spark in relation to piston position. The Equus Xenon, also called the Innova, uses a xenon bulb to read settings and connects to the spark plug with an inductive pickup. While timing analysis can be performed at home, a repair manual for the vehicle make and model is necessary to determine if the timing is set correctly.

Instructions

1

Locate the timing mark and erence pointer, which are typically located on the crankshaft pulley, vibration damper or on the flywheel. Make sure the timing mark and pointer are clean and visible, using chalk to define the marks if necessary.

2

Connect the timing light battery clips to the vehicle battery, placing the red clip on the positive (+) battery terminal and the black clip on the negative terminal. Attach one end of the supplied inductive pickup leads to the bottom of the timing light handle and the other part to the number one spark plug cable.

3

Start the engine and run it until normal operating temperature is reached. Turn on the timing light by pressing the "On/Off" switch, and the timing light will begin flashing. Adjust the timing light barrel to direct the light toward the timing marks.

4

Note the position of the rotating timing mark in relation to the erence pointer. If the readings are within the range advised in the vehicles repair manual, the ignition timing is correct. If the timing reading is not in range, an adjustment or part replacement may be necessary

5

Press the "On/"Off switch to turn the light off after use, then turn the car engine off and remove the battery clips.

The Chevrolet Aveo is a subcompact car manufactured by GM Daewoo since 2002 and marketed under the Chevrolet brand. The most common engine for the Chevrolet Aveo in the United States is a four-cylinder, 1.6-liter engine with a double overhead camshaft. The timing belt on this vehicle synchronizes the rotation of the crankshaft with the rotation of the camshafts. The most important part of the timing belt installation process is keeping the crankshaft and camshafts properly aligned during the procedure.

Instructions

1

Remove the cable from the negative battery terminal with a socket wrench. Disconnect the front cover for the timing belt and remove the mounting bolts for the power steering pump if your vehicle is so equipped.

2

Place a socket wrench on the crankshaft bolt and turn the crankshaft clockwise. Align the timing mark on the crankshaft gear with the timing mark on the rear cover of the timing belt.

3

Loosen the retaining bolts on the water pump slightly. Turn the water pump counterclockwise with Special Tool J-42492-A to relieve the tension on the timing belt. Detach the timing belt from its gears.

4

Disconnect the cover for the engine with a socket wrench and detach the electrical wiring from the spark plugs. Remove the crankcase ventilation tubes and camshaft position sensor from the valve cover. Disconnect the valve cover and its gasket.

11

Install the mounting bolts for the power steering pump with a socket wrench and replace the front cover for the timing belt. Attach the cable for the negative terminal of the battery.

The Chevrolet 230 is a six-cylinder inline engine. The engine is quite reliable and was used in many General Motors, Studebaker and Checker vehicles. General Motors produced a large number of inline six-cylinder engines of the same configuration with different bores. High production equates to affordable and readily available parts; new ignition and tune-up parts for the Chevrolet 230 can be found on the shelves of many auto parts stores. Worn contact points and oxidized distributor cap electrodes are a few good reasons for a tune-up.

Instructions

Tune-up

1

Trace the spark plug wire from the first spark plug in the engine to the distributor cap and mark a corresponding line on the distributor housing straight down from the spark plug wire. Be sure the mark is visible on the distributor after the cap is removed.

2

Remove the distributor cap and rotor button from the distributor. The distributor is located on the left side of the engine when viewed from the front and the rotor button is inside the distributor cap.

3




Loosen the nut on the wire post of the distributor, using the small ignition wrenches, and remove the contact points and condenser wire. Remove the screws that attach the contact points to the distributor plate and remove the points.

4

Loosen, but dont remove, the screw that holds the condenser band to the distributor plate and push the condenser out of the band. Dont remove this screw because it is tough to get back in place and if its dropped in the distributor it is difficult to retrieve.

5

Install the new contact points with a gap set at .019-inch with a feeler gauge. Push a new condenser into the condenser band, re-tighten the band screw and attach the wire to the wire stud on the contact points.

6

Place a new rotor button on top of the distributor shaft and install a new distributor cap. Be sure the rotor button seats into the grove on top of the distributor shaft or it may aim at the wrong distributor post and cause harmful back firing.

7

Pull the spark plug wire off the first spark plug on the engine and remove it from the distributor cap. Remove that spark plug and replace it with a new one. Place one end of a new spark plug wire on the new spark plug and the other end in the hole of the newly installed distributor cap that corresponds with the mark made on the distributor.

8

Proceed in a clockwise direction and remove the next spark plug wire from the old distributor cap. Trace that wire to the spark plug, remove the spark plug and replace it with a new one. Install a new spark plug wire on this plug and place the other end of the plug wire in the next hole of the newly installed cap proceeding in a clockwise direction.

Repeat this procedure until all the spark plugs and wires are replaced with new ones.

9

Unscrew the wing nut on top of the air cleaner and remove it. The 1949 Chevy is equipped with an oil bath air cleaner. The oil bath air cleaner has a wire mesh type filter in it and contains oil to trap the dirt.

Dump the oil from air cleaner in a container for proper disposal. Internally clean the air cleaner with a spray brake cleaner. Refill the air cleaner with oil to the level line marked and reinstall it.

Engine Timing

10

Connect the timing light induction clamp to the spark plug wire of the number one spark plug. Connect the lights red clamp to the positive terminal of the battery and the negative clamp to any grounded bolt on the engine.

11

Loosen the distributor hold down screw a half turn. Disconnect the vacuum line from the distributor housing and start the vehicle.

12

Locate the timing marks through the bell-housing access hole, located on the front right side of the bell housing by aiming the timing light pulse at the hole.

13

Set the engine idle at 500 rpm, align the circle ball mark on the flywheel with the indicator mark on the bell-housing under the timing light strobe, by rotating the distributor shaft until the marks align perfectly. Lock down the distributor hold down bolt once the marks are aligned and recheck the timing to be sure it did not change after it was tightened.

Working on a car can sometimes be inconvenient, especially if the parts that need replacing or examining are underneath the vehicle and too close to the ground to easily access. Elevating the car with an automobile lift is one way to get at many automotive problems without twisting your arm and craning your neck to see whats happening. Fortunately these lifts arent hard to use.

Instructions

1

Drive the vehicle onto the lift. Some lifts have rails that you have to park the tires on, while other lifts have a cage that will grab the vehicle by the frame to support its weight. Once the vehicle is in place, put it in park.

2

Press the lift button. This will get the lift moving and it will begin to raise the vehicle up. Keep a careful eye on the vehicle as its lifted to make sure it isnt rocking or tilting, and make sure that its rising steadily rather than jerking up.

3

Stop the lift. Either take your hand off the lift button and the lift will stop, or push the actual stop button once the lift is in place. When the vehicle is in the air and the lift has a good hold of it, youre ready to get to work on the car.

Fuel injectors provide fuel to the engine. The injectors are comprised of a nozzle and a valve that help regulate the amount of fuel entering the combustion chamber. Fuel injectors are essential for peak engine performance, and can cut down on excessive fuel consumption and emissions. Changing the fuel injectors can take care of issues such as lean misfire, slow throttle response, and high hydrocarbon and carbon monoxide emissions.

Instructions

1

Relieve the pressure in the fuel system (fuel lines and fuel filter) by first locating the fuel pump fuse in the fuse box. If your vehicle does not have a fuel pump fuse, locate the relay that runs the fuel pump.

2

Start the car and pull the fuse or relay out while the engine is running. This will kill the engine quickly.

3

Dissipate the electric circuit by first disconnecting the negative cable from the battery terminal. Loosen the retaining bolt on the cable clamp with a wrench turned counterclockwise. Wait 10 to 20 minutes before proceeding.

4

Remove the entire air cleaner assembly, including the air box and intake tubing, by unscrewing the bolts and the hose clamp located at the throttle body assembly with a wrench or ratchet and socket. Once the screws and bolts are removed, pull out the entire air cleaner assembly and set it aside.

5

Locate and remove the bolts holding the injector retaining rail in place, if your vehicle is so equipped, to gain access to the injectors. To do this, disconnect the main fuel line located at the end of the rail with an open-end wrench. If there is an extra fuel line at the other end, remove it with the open-end wrench.

6

Remove the bolts on the fuel rail with a ratchet extension and socket. The fuel rail should come off with a little pressure once the bolts have been removed.

7

Unplug the fuel injector connectors by prying the spring clip loose with a flat head screwdriver. Once the spring clip is loose, pull the connector off the injectors.

8

Put on safety goggles then use a fuel injector puller to remove the fuel injectors. Slide the injector puller below the lip in the injector seat and pop the injectors out.

9

Check to see if any pieces of the old seal are stuck in the seat. Use the flat head screwdriver to remove the debris.

10

Remove the plastic caps attached to the new fuel injectors before installing them. Lubricate the O-rings with a little engine oil.

11

Install the new fuel injector. Ensure that the center line of the electrical connector is in sync with the corresponding mark on the intake manifold.

12

Reassemble the components by reconnecting and re-bolting any wiring or bolts that were removed prior to the installation of the fuel injectors. Re-attach the air cleaner assembly, fuel rail, and cable for the battery terminal.

The engine oil for the Suzuki DF60 marine motor should be changed every season. In some cases, it should be changed every 100 hours to ensure the longevity and maintenance of the engine. Changing the oil in the boat can be a messy job. But with the right equipment, you can do the job quickly and easily.

Instructions

1

Start the Suzuki DF60 motor and let it run for a few minutes. This will warm up the oil in the engine and make it easier to extract.

2

Open the engine cap and locate the dipstick tube. Engage the oil evacuation system to drain the oil from the engine. Loosen the oil filter with a filter wrench as the oil is draining.

3

Collect the oil in an oil pan or jug as it drains from the engine. Replace it with new oil. Use Suzuki 10W-40 engine oil. Pour approximately 1.8 quarts of engine oil into the receptacle.

4

Change the oil filter by unscrewing it. Replace it with a new oil filter and put the old one in a plastic bag for disposal. Use a funnel to ensure the oil is kept contained to the engine and does not cause a mess. Replace the oil cap.
