So Fix it

An engines firing order is the sequence that each cylinder is used in power delivery. The firing order for the 6.6L turbo diesel V8 in the 2004 Chevrolet Silverado 2500 2WD is 1-2-7-8-4-5-6-3.

Gasoline Versus Diesel

In a gasoline engine, the distributor or Engine Control Unit sends electricity to individual spark plugs to ignite fuel in each cylinder in a specific order. In a diesel engine it is determined by the order in which fuel is injected into each cylinder.

Cylinder 1

Engine firing orders always start with cylinder number one, which on this engine is located at the front left of the engine from the drivers point of view.

Cylinder Banks

GM V8 cylinders are numbered 1-3-5-7 on the left (drivers) side of the engine, and 2-4-6-8 on the right (passenger) side.

If you have gotten into an accident or you are repairing a 2004 Dodge Stratus that simply needs a new grille and bumper, you can visit any official Dodge retailer to order replacement parts.

If you are driving down the road in your Chevy Tahoe and you notice a light on the dash for "tire failure" or "low tire pressure" you might become alarmed. Today more and more vehicles are being manufactured with tire pressure monitor systems called TPMS. The TPMS was designed for driving safety because most people never take the time to even look at their tires or check the air pressure. Low air pressure in a tire is the leading cause of tire failure and can lead to accidents. If you have a TPMS monitor that is not working properly, you can troubleshoot it with a few easy steps.

Instructions

1

Walk around your Tahoe and look at each tire to see if one of them looks low.

2

Slide the air pressure gauge over each valve stem to check each tire and make sure that it is inflated to the proper psi. The proper psi is noted on the car door. Never go by the maximum inflation noted on the tire. You must always go by what is indicated on the car door. Improper inflation will cause the TPMS unit to flag a problem.

3

Take your TPMS computer scanner out of the box and become familiar with the settings. You will need to push the buttons on the front to find your make and model of car. Press the button to enter the scan mode and walk around to each tire. Press the button at each tire until you get an indication that the scanner cannot find the TPMS unit. This is the unit that needs to be changed.

The 2004 Chevy Trailblazer base model came with a 4.2-liter inline six-cylinder engine and a four-speed automatic transmission. Your catalytic converter is located between the exhaust manifold and the muffler. A faulty catalytic converter can result in poor performance and higher emissions levels that will cause you to fail an emissions test. Replacing your catalytic converter is a straightforward task, but the transmission mount has to be removed because of the length of the catalytic converter assembly.

Instructions

Removal

1

Park the vehicle on a level surface and set the parking brake. Lift the front of the vehicle into the air with a floor jack and place jack stands under the front frame rails. Lower the vehicle until it rests securely on the jack stands. Allow the engine and exhaust to cool completely before continuing.

2

Position yourself under the vehicle so that you can clearly view the catalytic converter and its connection to the exhaust manifold. Locate the front oxygen sensor that is positioned just after the first flange and disconnect the pigtail from the wiring harness. Follow the catalytic converter piping after the converter to find the rear oxygen sensor. Disconnect the rear oxygen sensor pigtail from the wiring harness.

3

Place the oxygen sensor socket over the front oxygen sensor so that the pig tail extends through the slotted portion of the socket. Rotate the sensor counterclockwise with a ratchet to remove the sensor from the exhaust. Apply heat with a propane torch around the base of the sensor, if it is difficult to remove. Repeat for the rear oxygen sensor and label each one accordingly; they are not interchangeable and must be installed in the same position.

4

Place one jack stand at the rear and one under the front of the converter assembly, and elevate them until they make contact with the converter assembly. Remove the nuts securing the converter assembly to the exhaust manifold with a ratchet and socket. Remove the nuts securing the converter assembly to the rear muffler pipe.

5

Place a floor jack under the transmission and place a small block of wood on the jack arm. Raise the jack until the wood makes contact with the case of the transmission, but do not apply any upward force. Examine the transmission support that runs between the two frame rails to find the two center access holes. Remove the bolts securing the transmission mount to the transmission support with a socket and ratchet.

6

Remove the bolts securing the transmission support to the frame rails. Lower the transmission support from the vehicle and set it aside. Remove the bolts securing the transmission mount to the base of the transmission. Remove the catalytic converter and transmission mount from under the vehicle.

7

Pry the rubber hangers from the old catalytic converter assembly with a pry bar and set them aside. Set the transmission mount aside, with the rubber hangers attached.

Installation

8

Examine the rubber hangers for any damage or wear and replace as necessary. Install the transmission mount, with the rubber hanger bracket attached, to the transmission. Install the mounting bolts and tighten to 48 foot-pounds with a torque wrench.

9

Set the catalytic converter assembly onto the jack stands so that the flanges at both ends meet up with the exhaust manifold and muffler assembly. Lift the catalytic converter assembly as necessary and install the rubber hangers at the transmission mount to the metal hangers on the converter assembly.

10

Lift the transmission support into place between the frame rails and install the retaining bolts. Install the transmission mount to transmission support nuts through the access holes and tighten to 35 foot-pounds.

11

Install a new gasket at the front and rear of the converter assembly. Slide the converter assembly rear flange over the studs for the muffler pipe. Install the rear mounting nuts hand tight. Install the front converter flange to the exhaust manifold and install the mounting nuts hand tight. Tighten the mounting nuts for both flanges one turn at a time until they are tightened to 33 foot-pounds.

12

Remove the jack stands from under the converter assembly. Clean the oxygen sensor threads with a wire brush and apply copper anti-seize to the threads. Install the both oxygen sensors to the converter assembly until hand tight. Tighten both sensors to 30 foot-pounds with a torque wrench and oxygen sensor socket. Plug the oxygen sensor pigtails to their respective wire harness connectors.

13

Lift the front of the vehicle off the jack stands and remove the jack stands from under the vehicle. Lower the vehicle to the ground and remove the floor jack.

Traction control may be any method of reducing the loss of traction that occurs when the driver applies too much throttle for the current road conditions. It is a secondary function of the anti-lock braking system, or ABS, in a 2004 Mustang. A hydraulic control unit, or HCU, typically has a hydraulic line for each wheel and and an additional line for the master brake cylinder. An HCU with traction control has a sixth hydraulic line for the traction controls brake cylinder.

Instructions

1

Disconnect the cable from the negative terminal of the Mustangs battery with a socket wrench. Detach the electrical connector from the ABS control module. The ABS control module is a small, box-shaped component that sits on top of the HCU in the engine compartment. The traction control module, or ABS control module, determines the braking force to apply to each wheel in order to minimize the loss of traction.

2

Remove the brake lines from the HCU with a socket wrench. Plug the open ends of the brake lines with shop rags to prevent brake fluid from leaking out of the brake lines.

3

Remove the nuts that attach the HCU to its bracket with a socket wrench, and detach the HCU from its bracket. Detach the electrical connector from the brake pump motor.

4

Disconnect the mounting screws from the ABS control module with traction control by using a socket wrench. Separate the ABS control module from the HCU.

5

Mount the new ABS control module with traction control to the HCU. Fasten the mounting screws for the ABS control module with a socket wrench. Connect the electrical connector for the brake motor pump.

6

Mount the HCU to its bracket, and tighten the bracket nuts to 13 foot-pounds with a torque wrench. Remove the shop rags from the open brake lines, and attach the brake lines to the HCU. Tighten the fittings for the brake lines to 14 foot-pounds with a torque wrench.

7

Attach the electrical connector for the ABS control module. Connect the battery cable to the negative battery terminal with a socket wrench.

The Subaru Impreza is a four-door passenger vehicle with all-wheel drive which has been in production since 1992. The WRX is a version of the Impreza that has a turbocharger. The 2004 model features a four-cylinder, 2.0-liter engine with a double overhead camshaft. This engine uses a timing belt to drive the camshafts with the crankshaft, allowing the cylinder valves to open and close in the correct sequence.

Instructions

1

Remove the cable on the negative battery terminal with a socket wrench. Disconnect the V-belt and the crankshaft pulley from the engine. Remove the left timing belt cover, right timing belt cover and front timing belt cover in that order.

2

Disconnect the guides for the timing belt with a socket wrench if your vehicle has a manual transmission. Remove the No. 1 idler pulley, timing belt and the No. 2 idler pulley in that order. Disconnect the timing belt tension adjuster assembly.

3

Push the adjuster rod on the timing belt adjuster down with a constant pressure of 66 lbs. until the end of the adjuster rod reaches the surface of its cylinder. Place a 0.08-inch Allen wrench into the pin hole of the cylinder to hold the adjuster rod in place.

4

Install the timing adjuster and tighten its retainers to 29 foot-pounds with a torque wrench. Attach the the No. 2 idler pulley and No. 1 idler pulley in that order. Tighten the retainers for both pulleys to 29 foot-pounds.

5

Turn the crankshaft sprocket clockwise to align its timing mark with the timing mark on the oil pump. The double lines on the left intake camshaft must align with the double lines on the left exhaust camshaft sprocket. The double lines on the right intake camshaft must align with the double lines on the right exhaust camshaft sprocket.

6

Place the new timing onto the sprockets with the arrow pointing in the clockwise direction. The "A" mark on the timing belt must align with the timing mark on the crankshaft, The "B" mark aligns with the left intake cam shaft, the "C" mark aligns with the timing mark on the left exhaust camshaft, the "D" mark aligns with the timing mark on the right intake camshaft and the "E" mark aligns with the right exhaust camshaft.

7

Attach the belt idlers and tighten their mounting bolt to 29 foot-pounds with a torque wrench. Remove the Allen wrench from the cylinder on the timing belt adjuster.

8

Replace the guide for the timing belt if your vehicle has a manual transmission. Ensure that the clearance between the guide and the timing belt is between 0.019 and 0.059 inches Tighten the retainers for the timing belt guide to 7 foot-pounds.

9

Replace the timing belt covers and tighten their mounting bolts to 3.5 foot-pounds with a torque wrench. Connect the crankshaft pulley and tighten its mounting bolt to 94 foot-pounds. Install the V-belt.

The 2004 Nissan Xterra is equipped with disc-type front brakes. This type of brake uses two pads pressing against a disc-shaped brake rotor to create friction, which stops the vehicle. If the brake pads become excessively worn and are not replaced, the rotor can be damaged. If this happens, you will need to remove the rotor and either have it repaired at a machine shop or replace it with a new one. To remove the rotor and bearing assembly, you will first need to remove the brake caliper. The procedure differs slightly on 4WD vehicles.

Instructions

1

Loosen the wheel lug nuts. Raise the front of the vehicle with a jack and support each side with a jack stand. Remove the lug nuts and take off the wheel.

2

Saturate the entire brake assembly with brake fluid and allow it to dry. This will remove the dangerous dust generated by the brake pads.

3

Remove the three bolts that attach the brake caliper. There are two bolts that face inward, and one that faces downward.

4

Rotate the caliper off the rotor and use a piece of wire to suspend it from the SUVs body. This prevents strain on the brake lines.

5

Remove the free running hub assembly on 4WD models by removing the six bolts that hold it in place. Pull it off the hub. This step does not apply to 2WD models.

6

Use a flat screwdriver to remove the lock washer from the center of the hub. For a few dollars, you can also obtain a special tool for removing the locking washer. The lock washer is only present on 4WD models.

7

Remove the wheel bearing locking nut from the center of the hub by turning it counterclockwise. On 2WD models, you can use a large pair of needle nose vice grips to remove it. On 4WD models, you will need the special removal tool. The tool is available from Nissan dealers or you can usually rent it at tool-rental agencies or auto-parts stores.

8

Pull the rotor and hub assembly off the axle. If it is stuck, use a rubber mallet to gently tap it around the edges.
