Many motor vehicle accidents occur because other drivers and pedestrians dont see other vehicles until its too late. The daytime running lamp system on a 2004 Toyota Corolla turns on the headlamps at a reduced brightness level whenever the engine is running in order to combat this problem. This system helps other drivers and pedestrians to see the vehicle, reducing the likelihood of accidents and other potentially dangerous situations. In order to service the daytime running lamp system and make certain repairs, the daytime running lamp relay must be disconnected from the engines wiring harness.

Instructions

1

Turn off the engine and apply the Corollas parking brake. Shine a work light under dashboard, near the upper-right pedal area.

2

Locate the daytime running lamp relay; it is mounted on the right side of the foot well area. It is attached to the right under-dashboard wall, adjacent to the gas pedal. It is a small, square black relay and is third in a row of relays, furthest from the firewall.

3

Lift the locking tab on the relays connector with a small flat-head screwdriver and remove the relays electrical connector.

4

Start the engine and confirm that the daytime running lamps do not turn on. When youre done with your testing or repair, reconnect the daytime running lamp relays electrical connector and confirm that the lamps operate properly.

Diesel engines are more commonly found on larger trucks. The standard engine in a 2004 Dodge Ram 2500 is a six-cylinder, 5.9-liter, turbocharged diesel engine. This engine uses a high-pressure fuel injected system to deliver fuel to the engine. The fuel injectors on the 2004 Dodge diesel engine are located on top of the engine. Removal requires a special tool. You will also need to remove the fuel in the fuel lines before replacing the injectors.

Instructions

1

Loosen the bleed bolt on the fuel rail with a socket wrench. Push the fuel primer on the fuel transfer pump until the fuel coming from the bleed valve no longer has air bubbles. Tighten the bleed bolt to 72 inch-pounds with a torque wrench.

2

Disconnect the negative battery cable by loosening the terminal nut with a socket wrench. This will prevent the accidental discharge of fuel as you remove the fuel injectors. Disconnect the valve cover with a socket wrench and detach the fuel lines from the fuel injectors.

3

Remove the retaining nut for the high-pressure fuel connector on each fuel injector. Disconnect the high-pressure connectors from the fuel injectors with tool 9015.

4

Disconnect the exhaust rocker arms with a socket wrench. Remove the retaining nuts from the solenoid wire, located on top of the fuel injectors. Disconnect the hold-down clamp bolts on the fuel injector. Remove the rocker-housing bolt with a socket wrench.

5

Connect the lower half of the mounting stud on tool 9010-2004 to the center of the bridge for the rocker housing. Connect the upper half of the mounting stud on tool 9010-2004 to the lower half of the mounting stud.

6

Connect the handle of tool 9010-2004 to the mounting stud on the tool. Tighten the nut on the tool to loosely connect the handle to the mounting stud. Connect the lower half of the clam shells on the special tool to the sides of the fuel injector. Connect the upper half of the clam shells to the head of the tool handle.

7

Slide the retaining sleeve over the pivoting handle of tool 9010-2004. Push the handle of the tool down to force the fuel injectors out of the cylinder heads. Remove the fuel injectors from the cylinder heads.

The inner tie rod of the 2004 Chevrolet Silverado connects the outer tie rod to the center link. The center link crosses the center of the vehicle to link the driver and passenger side tire to move both tires the same distance on each side as the steering wheel turns. The inner tie rods screw directly into the center link, and is engineered with a ball and socket design much like a hip socket. The linkage allows the wheel to turn while holding the tire precisely in line with the steering wheel. Over time, the ball and socket wears and the tie rod must be replaced to eliminate play between the tire and the steering wheel.

Instructions

1

Park the 2004 Chevrolet Silverado on a hard flat level surface such as the concrete floor of a garage. Set the parking brake. Block the rear tires with wheel chocks to prevent the truck rolling.

2

Jack the truck with an automotive jack. Place jack stands under the frame rails where the control arms attach. Lower the vehicle onto the jack stands.

3

Measure the length of the inner and outer tie rod steering linkage with the tape measure. Write down the measurement and where the measurement was taken from on the scrap piece of paper with a pencil.

4

Break loose the inner tie rod to outer tie rod jam nut with a metric wrench.

5

Remove the outer tie rod to steering knuckle retaining nut with a 3/8-inch drive socket and ratchet. Hit the side of the steering knuckle where the outer tie rods ball stud attaches several times to break the outer tie rod free from the steering knuckle. Remove the tie rod from the steering knuckle.

6

Unscrew the outer tie rod from the inner tie rod by hand. Use metric wrenches to turn the outer tie rod and prevent the inner tie rod from turning if necessary.

7

Find the appropriate insert from the inner tie rod tool to firmly hold the flats of the inner tie rod where it attaches to the center link. Install the sleeve of the inner tie rod tool over the tie rod to engage the insert and lock the insert into place. Attach the 1/2-inch drive long handled ratchet to the inner tie rod tool. Unscrew the inner tie rod from the center link.

8

Install the new inner tie rod using the tie rod tool. Thread the inner tie rod to outer tie rod jam nut down the shaft by hand.

9

Thread the outer tie rod onto the inner tie rod to approximately the same position it was in before. Attach the tie rod to the steering knuckle, torquing the retaining nut with a 3/8-inch drive socket and ratchet.

10

Measure the tie rod assembly again at the same points. Turn the main shaft of the inner tie rod with a wrench until the measurements match exactly. Tighten the jam nut while preventing the inner tie rod shaft from turning.

11

Lower the vehicle from the jack stands. Remove the wheel chocks. Release the parking brake.

12

Align the vehicle to the factory specifications with an alignment machine for proper handling and minimal tire wear.
