Igniting a Spark
Your Volvo has thousands of parts in it. Some play a crucial role in the car, while others do not. Some are used all the time, while some are needed only for a specific time. One of the latter is your Volvo’s ignition coil. Also called a spark coil, the ignition coil is an induction coil in the automobile’s ignition system. The Volvo ignition coil transforms a storage battery’s 12 volts into the thousands (which sometimes could reach as high as 120,000 volts) needed to ignite the spark plugs. Invented by A. Kent Atwater in 1921, the ignition coil is a simple transformer that has two sides: the 12 volt or primary side and the high voltage or secondary side. The primary side contains a few hundred turns of a large diameter wire and it builds up the magnetic field in the coils. On the other hand, the high voltage side contains thousands of turns of small diameter wire. The coil uses electromagnetic induction to create the high voltage. When the voltage in the primary side is turned off, the collapsing magnetic field in the secondary side induces a voltage in the secondary side, producing thousands of volts. In older vehicles, a single, large ignition coil would serve all the spark plugs, distributing voltage via an ignition distributor. In modern systems, the distributor is omitted and ignition is controlled electronically, instead. Much smaller coils are used with one coil for each spark plug or one coil serving two spark plugs (so two coils in a four-cylinder car). These coils may be remote-mounted or they may be placed on top of the spark plug (coil-on-plug or direct injection). Where one coil serves two spark plugs (in two cylinders), it is through the “wasted spark” system. In this arrangement, the coil generates two sparks per cycle to both the cylinders. The fuel in the cylinder that is nearing the end of its compression stroke is ignited, whereas, the spark in its companion nearing the end of its exhaust stroke has no effect. The wasted spark system is more reliable than a single coil system with a distributor and cheaper than coil-on-plug. Where the coils are remote mounted, they may all be contained in a single molded block with multiple high-tension terminals. This is commonly called a coil-pack. Your Volvo ignition coils are part of a larger system, which is the ignition system. The ignition system is part of an even larger engine system. The ignition system’s primary responsibility is the timely burning of the fuel-air mixture in the engine. Your Volvo user’s manual would carry the recommended service interval for your ignition system, including your Volvo ignition coil. Your Volvo engine might run rough, buck, surge, stall or even get poor fuel economy. These are signs that your ignition system might need servicing as they are potentially an ignition system problem. When this happens, drive to the nearest Volvo dealership and have a qualified technician take a look around. Your Volvo engine might be in problem in the long run.

Understanding Your Auto Warranty
The auto warranty is something everyone thinks about when they are purchasing a car, but few of these people realize that they need to think about it after that as well. You go into a dealership, which convinces you to purchase an auto that is perfect for you. What seals the deal, in many cases, is the fact that the auto has an auto warranty on it. You think that they could not or would not offer a warranty on a product that wasn’t up to standards. So, you purchase your car and get your auto warranty. Regardless of the car, the make or model number, you simply shove that auto warranty into the glove box and call it done. But, what you need to do is to know what is covered on that warranty, what you need to do to get those services, and what you need to do to keep that warranty up to date. Getting the information that you need to make a decision about your auto warranty is also important. For many people, they may not even realize that they should read the thing! You would be surprised at what is and isn’t covered in that warranty. If you have one and you haven’t read it, dig it out and get going. What you will want to know first of all is what things it cover. Does the auto warranty cover things such as parts and oil changes? Does it cover the tires, brakes and the body work? Now that you know that, do you know what to do to get the services that it covers? Read on. Learn where you will need to go to get these services, if there will be any fee and what happens if you don’t go to the right location. Lastly, you also want to know about the auto warranty expiration date if there is one. In some cases, you may actually be able to increase that amount of time by purchasing a warranty extension. The auto warranty can offer many things after all. For more information please see <a href="http://www.auto-warranty-help.co.uk" target="_blank">http://www.auto-warranty-help.co.uk</a>

How To Negotiate Car Repairs
Everything is negotiable, it just comes down to if you want to put forth the effort to negotiate. In my life I have owned no less than 15 cars , that means car repairs. When your car is in the shop for repairs it’s a unique situation, you have no control or true knowledge of what REALLY is needed and what isn’t. There have been several special reports on news programs with undercover cameras showing mechanics damaging or lying to customers about repairs that are needed. The fact that it is even possible creates a situation that should also be taken advantage of by the consumer. Chances are pretty good that your mechanic is over charging you for something, if you take a good look at your invoice after you have had a major repair it has to be somewhat of a surprise that the gizmo that controls your anti lock brakes is $1700.00. There has to be a huge mark-up on the price of an item that is a must have, and you can only get it from the dealer. Car repairs can be negotiated just like anything else, more so even. Your mechanic or service manager at the dealer, knows for a fact that you are being over charged, that means that all you have to do is ask for a discount. If your mechanic is worth his salt he calls you before he does any work on your car, that is when the negotiation should start. When your mechanic tells you that you need a new flex capacitor and it cost around $800, your first reaction should be Can you give me a better price? Or better yet Can you do it for $700 . You need to make it clear from the very beginning that you want a discount. A ten percent discount is always a good starting point, you are only trying to get a small discount, which is better than nothing. The biggest mistake you can make is to wait until your car repair is finished. At that point he basically is holding your car hostage until you pay him, so that means he is in full control of the negotiation. The very little control we do have is before any work is done, because we still have the ability to say no thanks I’ll take it somewhere else. Most people want a discount, but most people don’t like negotiating. Let’s face it, it’s not for everybody. The reason car repair is set up for negotiation is because your mechanic or service manager knows that he can give you a discount but he certainly is not going to offer it. You’ll be surprised to see how easy they will give you 10% just for asking. The next time your you need a car repair follow these steps to get a 10% discount:: 1. Make sure you tell the service manager or mechanic to call you BEFORE he does any work to your car. 2. Always ask for an estimate when he tells you what repairs you need. 3 What ever amount he says, ask for at least for a 10% discount. It’s much better saying a specific price instead of 10%, so make sure you have your math ready. That’s it. No one said it was complicated, you just have to be willing to ask. Your’e going to be surprised how easy it is, and wonder why you didn’t do it sooner. Now take your 10% and do something for yourself,…. you earned it. http://www.ClickForInfo.netTodd C.
