The new 2008 Chevy HHR comes in five different models, and there are plenty of HHR accessories for you to choose from to customize your new car to your own personal tastes. Here&amp;#39;s a look at some of the options.&lt;br&gt;&lt;br&gt;The LS is the basic model and the lowest price. As such, the HHR accessories on this vehicle are fewest. However don&amp;#39;t let this deter you. You get a lot for what you pay for and there are plenty of add-on options. The Chevy HHR accessories included in the LS are a 149-horse power ECOTEC engine, remote keyless entry, power locks and doors, AM/FM/CD stereo system, and remote vehicle starter system available when you purchase the automatic transmission instead of standard. Some notable auto parts and accessory options are OnStar Navigation, four wheel antilock braking system, side impact air bags, MP3 player, and XM satellite radio.&lt;br&gt;&lt;br&gt;The next step up from the LS is 1LT. This model sports the same standard HHR accessories as the lesser-priced LS model, but includes sixteen-inch custom-spoke painted silver metallic wheels, an eight-way power driver&amp;#39;s seat, thirty-six AM/FM radio presets, and MP3 player. The 1LT also has the same accessory options as the LS but with the addition of some wonderful features such as fog lamps, rear spoiler, sunroof, leather seats and steering wheel and a larger ECOTEC engine. The Chevy HHR 1LT is a more luxurious ride with more power and comfort than the LS.&lt;br&gt;&lt;br&gt;The Panel LT is the next evolution in the HHR series. This model is very similar to the 1LT, with the obvious exception that there are no side windows behind the driver and passenger seats. The duty of this kind of vehicle is mostly for cargo, and the standard Chevy HHR accessory options are geared towards that job. Among the standards included are 175 horsepower ECOTEC engine, seventeen-inch painted aluminum wheels, gas-charged shocks and suspension, storage compartments in the rear floor, and rear power outlet. Optional auto parts and accessories for the Panel LT are leather interior, sunroof, and electronic traction control to stabilize the vehicle.&lt;br&gt;&lt;br&gt;The top of the line HHR is the 2LT. The standard options have already been named in the previous vehicle descriptions. The remaining standard HHR accessories are exclusive to the 2LT: four-wheel ABS braking system, eight-way power driver&amp;#39;s seat, Pioneer seven-speaker sound system, and auto-dimming rear view mirror. The optional auto parts and accessories are a shopping list of everything already mentioned, with the exception of some of the cargo-related options offered with the Panel LT.&lt;br&gt;&lt;br&gt;The final model of the Chevy HHR series is the 2LT Special Edition. This vehicle includes all the options of the 2LT but with curb appeal added to the mix. The standard auto parts and accessories include seventeen-inch black chrome wheels, black chrome exterior package, fog and head lamps with smoked lenses, black roof side rails, leather steering wheel, and exterior colour-keyed running boards and accent stripe. &lt;br&gt;&lt;br&gt;No matter which Chevy HHR model you choose, you will be sure to find an auto parts and accessories package that fits your budget and style. Take the model of your choice, and add some Chevy HHR accessories from this &lt;a class=&quot;external&quot; href=&quot;http://onlineautorepair.wetpaint.comhttp://www.auto-facts.org/auto-parts-online.html&quot; rel=&quot;nofollow&quot; target=&quot;_blank&quot;&gt;auto parts online&lt;/a&gt; warehouse that offers enough variety to please any driver.&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;hr size=&quot;1&quot;&gt;&lt;br/&gt;</description></item><item><title>Check engine light problems</title><link>http://onlineautorepair.wetpaint.com/page/Check+engine+light+problems</link><author>mastertechmark</author><guid isPermaLink="false">http://onlineautorepair.wetpaint.com/page/Check+engine+light+problems</guid><pubDate>Sat, 16 Feb 2008 19:18:44 CST</pubDate><description>&lt;h2&gt;Check engine light help&lt;/h2&gt;&lt;br&gt;If you disable the check engine light, you also are disconnecting the bulb test function. The bulb check function is when the bulb is illuminated, behind the check engine light symbol when the key is turned on and the engine is not running.&lt;br&gt;&lt;br&gt;Most areas have state inspections or smog check points that verify the proper operation of this check engine light bulb test. If you have disconnected the check engine light, you will be in violation of the clean air act and will fail your state inspection or smog check.&lt;br&gt;&lt;br&gt;Disabling the check engine light has become a difficult procedure to accomplish, even if you were to ignore the law. The good news is, that it is easier to repair the malfunction than it is to disconnect the check engine light. &lt;br&gt;&lt;br&gt;Removing the check engine light bulb would require disassembly of the dash and removal of the instrument cluster. On most late model vehicles, this is a difficult task to complete. &lt;br&gt;Also on some models when you remove the check engine light bulb, your computer that handles the air fuel mixture will go into a backup mode.&lt;br&gt; &lt;br&gt;This will cause poor gas mileage and poor drivability. In essence your computer is monitoring the proper operation of the check engine light and its bulb. The technical term used to describe the check engine light bulb is the MIL or malfunction indicator lamp.&lt;br&gt;&lt;br&gt;&lt;h3&gt;Do not disconnect the check engine light&lt;/h3&gt;&lt;br&gt;Believe it or not the check engine light is your friend. It is there to notify you that your car is suffering from either a minor or a major malfunction.&lt;br&gt;&lt;br&gt;Removing the check engine light bulb is not only against the law, it is counter productive to your vehicle&amp;#39;s long-term health. Learning to fix your own check engine light malfunction can be a very rewarding experience.&lt;br&gt;&lt;br&gt;For detailed information on dealing with your engine light visit master tech marks page about how to &lt;a class=&quot;external&quot; href=&quot;http://onlineautorepair.wetpaint.comhttp://www.auto-facts.org/auto-scan-tool.html&quot; rel=&quot;nofollow&quot; target=&quot;_blank&quot;&gt;reset check engine lights&lt;/a&gt; properly!&lt;hr size=&quot;1&quot;&gt;&lt;br/&gt;</description></item><item><title>Motor Vehicle Department</title><link>http://onlineautorepair.wetpaint.com/page/Motor+Vehicle+Department</link><author>mastertechmark</author><guid isPermaLink="false">http://onlineautorepair.wetpaint.com/page/Motor+Vehicle+Department</guid><pubDate>Sun, 16 Dec 2007 10:56:24 CST</pubDate><description>Motor Vehicle Department &lt;br&gt;The motor vehicle department in your city or state is designed to help you update your automobile information, and these days, modern technology makes getting services from this department much easier than before. You can find cheap car insurance, find out about the car insurance company you are considering, and even discover where to have your motor vehicle repaired. Here are some of the great services that your motor vehicle department has to offer.&lt;br&gt;&lt;br&gt;Most of the time, that motor vehicle department is a place where you can renew your driver&amp;#39;s license, as well as your tags for your car. You can even get personalized plates for your vehicles (this will usually cost more than a regular tag) and renew your vehicle registration online now in most states, and you can also update certain information on your license. For instance, if your address has changed, or you would like to become an organ donor, you can submit this information on the website for the motor vehicle department in your state, and you should get a response confirming the changes in a few days. &lt;br&gt;&lt;br&gt;Vehicle insurance verification is another feature you can take advantage of at the motor vehicle department. If you need to get documents to keep in your car to show police in case you are stopped for anything, the DMV should be able to mail or email these documents to you, and you will also get information on the car insurance company you&amp;#39;ve chosen, so that you can keep track of the changes that may be taking place with insurance policies in your state. Many insurance companies are now partnering with DMV offices across the country, so you can get free information on cheap car insurance while you&amp;#39;re getting your license renewed, and you may even be able to get a car insurance quote while your registration is being updated. This especially a plus for Arizona car insurance, since mandatory insurance is available at the DMV, so that you can make sure you don&amp;#39;t have to pay any penalties if you are stopped, in case you decide to change insurance companies in the future.&lt;br&gt;&lt;br&gt;The next time you dread the idea of going to the DMV, remember that you can take care of many of your needs online, and take advantage of the benefits your motor vehicle department has to offer. And, be sure to find out all you can about cheap car insurance while you&amp;#39;re taking care of other vehicle obligations, so that you and your family can save money.&lt;br&gt; &lt;br&gt;&lt;br&gt;Marks favorite hobby besides cars and auto repair is &lt;a class=&quot;external&quot; href=&quot;http://onlineautorepair.wetpaint.comhttp://www.auto-facts.org/buildyourownwebsite.html&quot; rel=&quot;nofollow&quot; target=&quot;_blank&quot;&gt;building profitable websites&lt;/a&gt;.

By connecting certain iPOD automotive accessories, thousands of songs can be downloaded and accessed through your own car stereo system. Quality interfaces from Panasonic, JVC, Sony, and Pioneer can all be purchased new or aftermarket.&lt;br&gt;&lt;br&gt;Another useful iPOD auto accessories is the iPOD cup holder mount. This contraption fits conveniently in any standard cup holder and allows you to slide your iPOD into an easy accessible position so it won&amp;#39;t be sliding across your dash or passenger seat as you drive.&lt;br&gt;If you&amp;#39;re looking for an easier connection from your iPod to your car&amp;#39;s stereo, there are several options for you. The most economical is a wireless FM transmitter. This transmitter attaches directly into the headphones jack of your iPod and broadcasts music over a localized FM band within your car. The versatility of this item is that it can be brought from vehicle to vehicle no matter what the vehicle&amp;#39;s radio capabilities are. The only requirement is that the radio can pick up an FM signal.&lt;br&gt;&lt;br&gt;&lt;h3&gt;Long term ipod solution&lt;/h3&gt;&lt;br&gt;A more permanent and upscale stereo arrangement is available with Pioneer car accessories. Pioneer has a reputation for quality sound systems and crystal-clear audio. If you want a sound system above an iPod, look at what the line of Pioneer car accessories has to offer. The Pioneer CD-ID100II is an accessory that works as a connector between your iPod and your Pioneer car audio system, doubling as a charger for the iPod. Other options include surround sound, subwoofers, and a Bluetooth hands-free tuner for iPod controls.&lt;br&gt;&lt;br&gt;With all the great options for automotive audio accessories parts on the market today, there is no reason to settle for the stock stereo system that comes with your car when you buy it from the dealer. Both Pioneer and iPod have systems to fit any budget and any car, turning the listening experience into something worthwhile.&lt;br&gt;&lt;br&gt;&lt;h3&gt;Me and my ipod&lt;/h3&gt;&lt;br&gt;Connecting my ipod to my truck was the best thing I have ever done to releave the stress of my long daily drive to work.

Personalizing your Chrysler 300 has never been easier. Here are a few examples of how you can add a touch of luxury to your Baby Bentley.   &lt;br&gt;&lt;br&gt;Begin with custom car accessories like the Sherwood Dash Thirty-Four Piece Dash Kit for your dashboard to add a wooden accent to your interior. If you are willing to spare no expense to upgrade your interior, you can go with the Laurence Gartel Signature Series Dash Art that retails at $1300 US and up. Each of these dashes is one of a kind and comes with a signed certificate of authenticity.&lt;br&gt;&lt;br&gt;Next, choose quality auto accessories parts for your Baby Bentley, such as the Mopar OEM AM/FM 6-CD changer/MP3 Player and DVD Navigation Radio. These multi-faceted radios come with a color digital display which uses GPS technology to guide you turn-by-turn to any location in the United States or Canada. The unit also comes equipped with Sirius Satellite Radio technology. You can take advantage of this feature if you have a subscription to Sirius and the right antenna. This amazing system can set you back a cool two or three grand.&lt;br&gt;&lt;br&gt;&lt;h3&gt;  Luxury automotive accessories for the 300&lt;/h3&gt;&lt;br&gt;What kind of auto accessories parts do you need to get Sirius radio? Look no further than Mopar&amp;#39;s OEM Chrysler 300 Sirius Satellite Radio kit. The kit comes with a permanent but discreet antennae and receiver that wire directly into your radio. The cost is a manageable $350 US plus $12.95/mth subscription to Sirius.&lt;br&gt;&lt;br&gt;A great radio needs a great sound system. The Kicker Subwoofer Kit (estimated $500 US) will give you strong booming base. Double that with Kicker Premium Front and Rear Speakers (estimated $280 US), and you will have the envy of all custom car accessories.&lt;br&gt;Throw in either an All Sales Flame Rearview Mirror ($90 US) or All Sales Polished Billet Oval Rear View Mirror ($80 US), and DUB Custom Edition Floor Mats ($80 US for set) for those finishing touches.&lt;br&gt;&lt;br&gt;&lt;b&gt;Exterior automotive upgrades&lt;/b&gt;&lt;br&gt;&lt;br&gt;The exterior of your Chrysler 300 should be treated as much with quality auto accessories parts as the interior. Installing an E&amp;amp;G Classics &amp;quot;Phantom&amp;quot; Style Grille for $800 US would turn heads with its stainless steel design. However, this luxury item only fits the 2005 and 2006 models of the Chrysler 300.&lt;br&gt;&lt;br&gt;Grab a silver Xenon 6-Piece Fascia Auto Body Kit ($1800 US), for a stylish sporty look to your vehicle from front to back. To prevent from accidentally dinging your door on another car when you open it, invest in JT Auto Style&amp;#39;s Vertical &amp;quot;Lambo&amp;quot; Door Kit ($1000 US).

The flat rate mechanic can often break things in the repair area and then claim that these parts were broken before. And of course need replacement for a profit to the mechanic.&lt;br&gt;Performing your own automotive repairs will not only teach you valuable skills but will also make you less open to auto repair rip-offs and scams. &lt;br&gt;When you start a do it yourself auto repair job, you will be more successful, if you are able to continuously work on the vehicle until it is finished.&lt;br&gt;If you stop and leave the repair site, not only do you break the rhythm of the repair. But you may also forget something very important. The best chance for success is to start and finish the job in one motion. &lt;br&gt;A few tips to assure that you have everything you need. First double check the replacement parts. On first glance it may seem that this is the right part for the job.&lt;br&gt;I recommend taking the replacement part out of the box and holding it next to the part to be replaced. This will assure that you have a direct replacement part in that you will not have to leave the job site to switch out parts.&lt;br&gt;You also want to make sure that you have all the supplies needed to complete the repair. Things like rags, silicone, coolant, razor blades and other tools that may be required.&lt;br&gt;Know when the repair is over your head and get the needed online auto repair help before the repair operation snowballs into something ugly. This happens to me all the time and I have been doing this for 24 years. &lt;br&gt;Before you attack a needed auto repair do some research into  &lt;a class=&quot;external&quot; href=&quot;http://onlineautorepair.wetpaint.comhttp://www.auto-facts.org/autoservicemanuals.html&quot; rel=&quot;nofollow&quot; target=&quot;_blank&quot;&gt;online auto repair manuals&lt;/a&gt; when it comes to repairing your own car or truck. You may just avoid a disaster. &lt;br&gt;Your car or truck is a huge investment not to mention your life blood of an active lifestyle. When it comes to repairing your own car it can go one of two ways. &lt;br&gt;You can be successful and fix it right the first time. Or you can make matters worse by creating additional problems. The latter will increase total costs and the down time of the automobile in question.&lt;br&gt;&lt;br&gt;For more about &lt;a class=&quot;external&quot; href=&quot;http://onlineautorepair.wetpaint.comhttp://www.auto-facts.org/autorepairhelp.html&quot; rel=&quot;nofollow&quot; target=&quot;_blank&quot;&gt;online auto repair help&lt;/a&gt; give us a visit&lt;hr size=&quot;1&quot;&gt;&lt;br/&gt;</description></item><item><title>Automotive air filter story</title><link>http://onlineautorepair.wetpaint.com/page/Automotive+air+filter+story</link><author>mastertechmark</author><guid isPermaLink="false">http://onlineautorepair.wetpaint.com/page/Automotive+air+filter+story</guid><comments>reasons for diy auto repair</comments><pubDate>Sat, 10 Nov 2007 10:55:27 CST</pubDate><description>Quick story I had a friend of the family go into a quick lube and they sold her an air filter. &lt;br&gt;When replacing the air filter the oil changer wiped out the air filter housing and got distracted and left the rag in side and under the air filter. &lt;br&gt;&lt;br&gt;When he started it up the rag got sucked into the engine and bent an intake valve. &lt;br&gt;The shop did pay to have the engine fixed but the car never ran the same again. A flat rate mechanic at a dealership repaired the engine cutting corners and the car had multiple problems after the engine service. &lt;br&gt;&lt;br&gt;Most mechanics are not as good at putting engines together as the factory is. Even if they are not cutting corners.

Unfortunately, even though these types of mechanical failures create recognizable symptoms of poor performance, many technicians get caught up analyzing or over analyzing computer-controlled systems. When the root failure is related to a mechanical or hard part failure.&lt;/font&gt; &lt;font color=&quot;#000000&quot;&gt;&lt;font face=&quot;Times New Roman&quot;&gt;&lt;/font&gt;&lt;/font&gt;&lt;font color=&quot;#000000&quot; face=&quot;Times New Roman&quot;&gt;Automotive diagnostics used to uncover diagnostic trouble codes, may actually be the result of faulty mechanical components. That&amp;#39;s why it is important to follow a logical diagnostic routine. In this article we&amp;#39;ll take a look at just one basic automotive diagnostic troubleshooting procedure that can effectively isolate the root cause of many power train related failures.&lt;/font&gt; &lt;font color=&quot;#000000&quot;&gt;&lt;font face=&quot;Times New Roman&quot;&gt;&lt;/font&gt;&lt;/font&gt;&lt;font color=&quot;#000000&quot; face=&quot;Times New Roman&quot;&gt;Simple automotive diagnostics. Checking vacuum, while it may be low tech a vacuum gauge is a powerful diagnostic tool that can help you quickly determine an overall engine&amp;#39;s performance. Engine vacuum is simply a condition in which the pressure of gas. In this case air is less than the normal atmospheric pressure at sea level atmospheric pressure is approximately 14.75 psi, which corresponds to a barometric pressure of 29.5 inches of mercury.&lt;/font&gt; &lt;font color=&quot;#000000&quot;&gt;&lt;font face=&quot;Times New Roman&quot;&gt;&lt;/font&gt;&lt;/font&gt;&lt;font color=&quot;#000000&quot; face=&quot;Times New Roman&quot;&gt;This means that if you placed a long tube into a bowl of liquid mercury and remove the air from the opposite end the surrounding air pressure would force the Mercury almost 30 inches up the two. This works out to 2 inches of mercury for every one psi of air pressure.&lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; face=&quot;Times New Roman&quot;&gt;&lt;/font&gt; &lt;br&gt; &lt;font color=&quot;#000000&quot; face=&quot;Times New Roman&quot;&gt;&lt;/font&gt;&lt;font color=&quot;#000000&quot; face=&quot;Times New Roman&quot;&gt;&lt;b&gt;&lt;u&gt;Using vacumm for automotive diagnostics&lt;/u&gt;&lt;/b&gt;&lt;/font&gt; &lt;br&gt;&lt;font color=&quot;#000000&quot;&gt;&lt;font face=&quot;Times New Roman&quot;&gt;&lt;/font&gt;&lt;/font&gt; &lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;Understanding the relationship between pressure and vacuum is important to avoid misinterpretation of automotive diagnostics. The OBD to automotive sensor that measures vacuum is the map sensor or manifold absolute pressure. &lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;&lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;With the key on and the engine off the map reading will be about 29.5 inches of mercury, which is the equivalent of atmospheric pressure at sea level. Once the engine is idling the map sensor reading will drop to about 11.5 inches of mercury. At first glance, you may think that this reading is indicative of a serious mechanical problem. &lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;&lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;However, while this may appear to be a low vacuum reading. It is actually a normal pressure reading. Remember that map sensor voltage is measured in pressure and not vacuum. To determine actual engine vacuum simply subtract the running map sensor value from the key on the engine off value. &lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;&lt;/font&gt;&lt;br&gt;&lt;font color=&quot;#000000&quot; size=&quot;2&quot;&gt;This means that if the running value is 11.5 inches of mercury actual engine vacuum is 18 inches. A healthy engine will typically produce between 18 and 20 inches of vacuum at idle with closed throtle and no engine load.

Basically the federal government wants to notify the driver that the vehicle may be contaminating the atmosphere. Yes, the main function of this light is for emission system compliance.&lt;br&gt;&lt;br&gt;The check engine light comes on to notify the driver that a code has been set in memory. Sometimes the code relates to a serious problem, but in most cases it&amp;#39;s a minor malfunction or intermittent condition.&lt;br&gt;&lt;br&gt;If you have your own auto scan tool. You can answer the number one question in everyone&amp;#39;s mind when that service engine soon light comes on. Of course the question is, why is this light on. An auto scan tool can give you the answer quickly and easily.&lt;br&gt;The automotive scan tool is a lot easier to read and use than most people realize. Your auto repair center is counting on you not finding this out.&lt;br&gt;Automotive scan tool or car code reader. This is my second article on the subject of why everyone should have one.&lt;br&gt;&lt;br&gt;Connecting the auto scan tool to your vehicle and pulling out the codes and then resetting the light is your auto repair shops favorite job. They don&amp;#39;t have to get dirty or bust their knuckles, and it pays very well.&lt;br&gt;&lt;br&gt;In this next example of using an automotive scan tool and reading scan tool data. I&amp;#39;m going to give you a very common code that you could find set in the computers memory. I come across the oxygen sensor voltage low or high code all the time. Many mechanics when they find this code just want to go ahead and replace the oxygen sensors. This may not be the right thing to do.&lt;br&gt;&lt;br&gt;When you pull this code up on your automotive scan tool, the first thing you want to do is reset the code and see if it returns. If the check engine light has come back on and this code has reset the second thing you want to do is read the data stream for the oxygen sensors. Reading scan tool data for this code using the automotive scan tool is a lot easier than you would think.&lt;br&gt;&lt;br&gt;Mark is a certified master mechanic that has set up a car questions website for the do it yourself auto mechanic.
