The thermostat in your car serves the purpose of regulating the temperature so it stays at a desired level.  To achieve this, it controls the cooling and heating mechanisms that control the heat flow throughout the system.  The thermostat manages the amount of coolant in the internal combustion engine.  A thermostat is necessary in all liquid cooled engines.

If your thermostat isn’t working correctly it may be due to several reasons.  First, the thermostat may be affected if the water pump is failing.  The thermostat may also be affected with an overheated engine or if coolant is leaking.

Make sure you have a mechanic look at your thermostat on a regular basis.  It plays a key position in keeping your engine cool, so it needs to be replaced every few years.

Also, if you don’t replace your thermostat when it’s time, you may find yourself with additional problems, such as emission problems, knocking with acceleration, and poor fuel-economy.  This is why it is important to have a good auto warranty.  You don’t want to find yourself paying unnecessary repair costs.

After recalling 944,000 vehicles, GM has had to discontinue its HotShot windshield washer system, which was responsible for an electrical short.  So far, the malfunction has caused 34 auto warranty claims and three fires as a result of a short in the circuit board, which caused the control-circuit ground wire to overheat.

GM claims that the system’s supplier, Microheat, is responsible for the dangerous glitch.  GM feels that Microheat should pay the $20 million to $25 million that has been estimated for the cost of the recall.  However, the supplier claims that it is still owed by GM for tooling and parts.  Microheat is already suffering financial troubles, which means the recall could cause Microheat to go out of business, even though its innovative system is great for getting rid of insect remains in warm months and ice in cold months.

Vehicles that were involved in the recall are the Cadillac DTS and Escalade; the Buick Lucerne and Enclave; the GMC Yukon, Sierra and Acadia; the Hummer H2; the Saturn Outlook; and the Chevrolet Avalanche, Silverado, Suburban and Tahoe.

The 2009 Pontiac G8 GXP with 402 hp will be listed at $37,610, which is at least $1,000 cheaper than the Dodge Charger SRT8 and you still get an impressive auto warranty.

The GXP has a 402 hp, 6.2-liter V-8 engine with 402 pounds of torque, which is the most powerful Pontiac of all time.  This vehicle has a six-speed automatic transmission that comes standard, however you can also get a six-speed manual for an extra $695.

For those of you who might think the 361-hp G8 GT already had enough power under the hood, don’t forget added horsepower isn’t the only impressive change to the GXP.  This car has a track-tuned suspension and steering, a unique interior, Brembro brakes and new car warranties.

Some people have suggested that the GXP is a BMW M5 killer, however, this car is such a great bargain that you could purchase one for you and your friend and still end up shelling out less than you would for a M5.

Cars need fuel pumps because the gas tank is on the opposite side of the car than the engine.  The purpose of the fuel pump is to bring the fuel to the engine.

Fuel pumps come in two varieties.  Vehicles that have electronic fuel injection systems use electrical fuel pumps.  Carbureted vehicles have mechanical fuel pumps.

The carburetor delivers fuel through a vacuum.  Here, the vacuum that brings the mixture of air and fuel to the engine also draws the gas along lines to the engine.  But, extra help is needed, so engines that are carbureted have a fuel pump that is mechanical.  This pump is located next to the engine of the vehicle.

Electronic fuel injection is a system of delivery in which gas is squirted into the chambers of the engine.  The fuel pump is next to, or inside of the gas tank.

Cars with electronic fuel injection typically don’t have the fuel pump fail.  However, when it does, the car will start to sputter and eventually die.  In addition, it won’t start back up. It is important to protect yourself with an auto warranty so if your car fails you won’t have to pay unnecessary repair expenses.

In future car accidents a circuit could be as crucial to survival as a seat belt.  Congress made seat belts mandatory in the 1960’s, which was revolutionary in car safety.  Since then, seat belts have greatly reduced deaths.  Now, there is an additional safety revolution in the midst.  The National Highway Traffic Safety Administration has employed a new standard.  This makes electronic stability control equipment a mandatory component in all cars.  The adoption of ESC will save approximately 10,000 lives every year.

Most luxury vehicles already come with ESC.  Other models offer it as an option.  This is just one of the new safety advancements designed with the purpose of preventing auto accidents, not just protecting passengers.  The majority of these new features have a microchip base.  Many are still being perfected. So beware, you never know when new technology will fail.  However, new car warranties will save you from unnecessary expenses.

Many motorists are finding it easiest to buy a package of safety options, rather than individual gadgets.  Lexus, for example, places an emphasis on how its safety features work as a system.  It has a package with lane-departure warning, smart cruise control, and ESC.

Integrating such systems, and the yielding of throttle, brake, and steering raise the question: Do drivers need or want this much help?  Who is actually in charge of the wheel?  No matter the answer, an auto warranty is essential in protecting your vehicle with all of those fancy gadgets.

When purchasing a new car, it is up to consumers to do their homework before shopping.   This will ensure the best deal possible.  Three important tips will save you from unnecessary costs.

First, look around to find the best dealership.  One way to do this is to check the Internet about dealerships. Web searches can be a wealth of information. Many times you will find complaints or positive revues that could help you.  Also, it is a good idea to contact several car dealerships in your area to see which ones are going to respond quickly and be helpful.

Next, don’t buy alarm systems or dealer financing. These are two ways that consumers lose in the end. For example, when cars are manufactured they already have wiring installed.  However, automakers sell alarms separately for up to $1200.  This is added on to the price of the new vehicle.  Also, finance offices don’t usually give you the best deals.  A better option would be to put your money towards a much needed auto warranty.

Finally, sell your car before arriving at the dealership.  If you sell it yourself, you will get a much better deal than you would on a trade-in.

The bottom line is that any mechanical breakdown leaving a motorist stranded could wipe out all of the gains from a perfectly negotiated deal.  New car warranties should be an essential part of your purchase in order to protect you from unnecessary repairs.

A driver’s worst nightmare is to turn the key and have their car not start.  Sometimes your engine will turn over but for some reason the car just won’t start.  Do you know what to do if this happens to you? Of course you could call a mechanic.  However, without an auto warranty you might face costly repairs. There are three things that you should check on your own first.  A car relies on air, fire and fuel.  If a car doesn’t get one or two of these vital ingredients, it won’t start.

The first thing that you should check is to make sure the car has gasoline.  If there is an adequate amount, the engine might have been flooded.  You can floor the gas pedal for around ten seconds, but be careful not to pump it while you are turning the ignition.  If the engine is still not starting, tap the carburetor close to the gas line.  This can free the line if the needle valve is stuck.

It is also important to check for broken or loose spark plug wires.  Make sure to do this with the engine off.  The wires that go from the distributor cap to the spark plugs should be secured down on the ends.

Now that you have checked for fuel and fire, we move on to an air check.  If you own a car with a carburetor, take off the top of the air filter and look at the choke plate.  If it appears stuck, open or close it.  Then jiggle the plate in order for it to move freely.

Checking the three main ingredients, air, fire and fuel are a great place to start if your car won’t turn over.  However, you may need a mechanic if you can’t find anything wrong.  You never know when your car might breakdown, which makes it a necessity to have an auto warranty to protect you from costly repairs.

Because of the poor economy, Americans are trying to find ways to save at the gas pump.  Ford has put together some easy tips for all motorists, which suggest ways to alter their driving behavior.

First of all, drivers should slow down and keep a steady speed.  Consider driving 55 mph instead of 65 mph.  Just by following this simple tip you can improve your fuel economy 10-15%.  Also, by maintaining a constant speed and not pumping the accelerator you can avoid sending more gas to the engine.

Next, avoid aggressive driving to avoid wasting fuel.  Also, this will help you avoid wearing out brakes and tires.  Try to have a smooth acceleration and soft brake.

Don’t waste money idling.  Even in frigid temperatures, engines today don’t need to warm up.  After starting the vehicle, drive away gently.  Instead of idling in traffic and fast food drive-thrus, just turn you engine off.

Finally, purchase an auto warranty so that you aren’t afraid to have maintenance and repairs performed.  Maintaining your vehicle will ensure that it is running efficiently and has the best fuel economy possible.

More and more recent cars are being sold with all-wheel drive or four-wheel drive as an option.  Is this something that your really need?  Will it actually make you safer or is it just a way for automakers to make extra money?

As of now, there haven’t been any formal studies by the National Highway Traffic Safety Administration on the effectiveness or ability to prevent crashes, in regards to four-wheel drive.

To decide if two or four-wheel drive is for you, you should make a list of the ways you will be using the vehicle and the conditions you will be driving in.

And ask yourself a series of questions.  For instance, do I live in an area with a lot of rain or snow?  Or, do I go on skiing trips often?  Do I travel on dirt roads, or off-road?  Also, will I be doing a lot of hauling?

These are worthwhile situations to have two or four-wheel drive.  However, if you’re just traveling on roads where there are mild conditions, you probably don’t need it.

Having two or four-wheel drive can benefit you greatly if you’re going to use it often.  However, if you really don’t need it, it might just be a waste of money.  This is a terrific feature, but you will want to purchase an auto warranty to ensure that you aren’t going to pay repair costs that are unnecessary down the road.

Consumers can experience sensory overload when walking down the car care isle at their local store.  It can be confusing to know what products to purchase, or even if you need to purchase them.  Some people assume that if you have a factory auto warranty that includes the finish, you don’t need to bother washing and waxing, but this isn’t true.

A factory auto warranty will protect you by ensuring that the paint job was sound, that they used quality paint, and that it was cured correctly.  However, new car warranties won’t protect you from oxidation that occurs over time.  This happens naturally if you don’t care for your finish.  Car wax serves the purpose of being a sacrificial layer between Mother Nature and your paint.

If new car owners want to keep their finishes looking great, they don’t have to spend a lot of time or money.  Preventative maintenance is the key for your finish, just like it’s under the hood.  All you have to do is wash your vehicle frequently with car care products.  Even just a basic car wash will do a lot to help protect your investment.  After washing, you can spray-on a wax that will boost the shine and extend the intervals between regular wax jobs.
