If you have owned a car for any length of time, you have probably already figured out that cars will break down from time to time. Cars are made up of a complex arrangement of mechanical and electronic parts, all of which have the capacity to fail or malfunction. Fortunately, replacement parts exist to replace virtually any component on your vehicle that breaks.

Replacement Parts

Automotive replacement parts are parts that are made to replace existing parts when they break. Replacement parts are manufactured by both the vehicle manufacturers and aftermarket parts manufacturers. You can by a replacement for virtually every component on your vehicle, including body panels, knobs, dials, wiring, belts, pumps, pulleys, sensors and even the mechanical parts such as the engine and transmission. Granted, if your vehicle is not a common make or model, you will often have a harder time finding replacement parts or have to get used parts, but the components are still out there and available for purchase.

OEM Parts

Original Equipment Manufacturer parts (OEM) are auto parts that were manufactured by the same company that made the original part. This means that the part is identical to the original item that was in your car in every way possible. OEM parts are often considered desirable by mechanics and vehicle restorers because they keep the vehicle in as close to original condition as possible.

High Performance Parts

Performance parts are designed to be more sophisticated and higher quality than the original manufacturer parts. These may correct design flaws that the original parts experienced. They may also be designed to improve performance by increasing horsepower or the capacity of a component. for example, a larger radiator to improve efficiency of the cooling system.

Used Parts

There is a large market for second-hand or rebuilt auto parts. Some components, such as alternators and starters, can be professionally rebuilt and used again. Rebuilding typically involves replacing the internal components of the part. Used parts can be purchased from a parts reseller such as a junkyard. Used parts tend to be less expensive than new parts and many used parts come with a warranty.

Pressed cork gaskets absorb oil that causes the gasket to expand during use. The additional expansion allows the gasket to provide a strong seal between rigid parts. Over time, heat causes cork gaskets to break down and become brittle. Installing a cork gasket correctly extends the life of a mechanical part where it resides and allows you to remove and reinstall a part without ruining the gaskets ability to create a seal.

Instructions

1

Remove old gasket material and debris from both the part and engine mounting surfaces by pushing a paint scraper across both surfaces using short strokes.

2

Dampen a clean rag with isopropyl alcohol.

3

Wipe both surfaces clean with the alcohol-dampened rag. Ensure no dirt or grease remains on either surface.

4

Puncture the end of a gasket adhesive tube with the point located on the top of the cap. Apply a 1/8-inch-thick bead of adhesive to the parts gasket mounting flange. Press a cork gasket firmly into the adhesive. Allow the adhesive to dry for 10 to 15 minutes.

5

Press the part--gasket side down--onto the mounting flange of the engine. Secure the part to the engine to seat the gasket.

The knock sensor in your car detects a low-frequency engine knock and sends an electrical signal to other parts of your car. This makes knock sensors vital to proper engine timing, fuel efficiency and power.

Preparation

Varying in location on different vehicles, knock sensors are often found in the engine block, intake manifold or the cylinder head. While specific tool sizes may also differ by engine, youll generally need a ratchet with a socket fitting the knock sensors nut. Before beginning, drain the engine coolant.

Replacement

After caully removing the electrical connectors cover from the sensor, use the ratchet and socket to unscrew and remove the knock sensor. Evenly thread the new knock sensor into the hole and tighten it. Innova Electronics Corporation instructs to tighten the nut to the engine manufacturers inch-pound torque recommendation then reconnect the electrical connector.

After the Replacement

After replacing the knock sensor, youll replace the engine coolant and ensure that its full. Next, you should start the engine and visually inspect for coolant leaks, then test drive the vehicle to ensure proper working order. If the "Check Engine" light was on, it should turn off after replacing the knock sensor unless theres another engine problem. Continue to inspect for coolant leaks over the next few days, just to be sure.

Everyone has a few items to carry with them on a regular basis, and car keys are generally one of those items. When you realize youve lost or misplaced the keys to your Nissan Titan, if might feel like the end of the world, but in reality, obtaining a replacement is fairly simple. Nissan dealerships and professional locksmiths have the capability to replace the keys to your Titan in a relatively short amount of time.

Instructions

1

Write down the vehicle identification number (VIN) of your Nissan Titan. Find this inside the drivers door panel. It is also visible from outside the vehicle on the bottom corner of the drivers side windshield. The VIN is also located in your purchase paperwork, registration and title.

2

Contact your local Nissan dealership or a professional locksmith service to request a new key for your Nissan Titan.

3

Provide the Nissan dealer/locksmith with the Titans VIN. If your Titans key has a computer chip, as most late-model vehicles do, that information is relayed to your Nissan dealer or locksmith by your VIN. Wait while your key is made and pay for the services rendered.

Youve lost or misplaced the keys to your 2002 Saturn and are understandably frustrated. Replacing them doesnt have to be a great hassle. Since Saturn uses transponder or "coded" keys that emit a frequency specially attuned to your cars ignition, youll have to order a set that will be not only cut but programmed. A new set is as near as your Saturn dealership or a reputable automotive locksmith. If you are unable to travel to a dealership, an automotive locksmith can meet you on site with your new keys.

Instructions

1

Call the dealership and see how much it will charge you for a new set of keys. The keys will have to be found in inventory, cut and then coded for your particular car. Once you get a price, do a little comparison shopping.

2

Call a reputable automotive locksmith, preferably one recommended by your auto mechanic or through a listing with the Better Business Bureau. A reputable locksmith will more than likely give you a lower price quote than the dealership.

3

Place your order for your keys with a vendor. Expect it to take four hours to get a set of keys from a dealership and less than that from an automotive locksmith. If you are unable to travel to the dealership, a locksmith is by far the best choice as he will bring the key to you and test it in your ignition.
