How Car Exhaust Systems Work

From Exhaust Gas Recirculation (EGR) Valves to O2 Sensors, your exhaust system has a critically important job to do to keep your car operating efficiently. Your vehicles exhaust system is engineered to withstand extreme conditions, including high exhaust temperatures, corrosive gasses, road salt (where applicable) and water. The vehicle's exhaust system performs three important functions. It directs exhaust gases from the engine to the rear of the vehicle, it treats the exhaust gases to reduce emissions and it reduces noise produced by the engine's combustion process. Key components of the exhaust system include: Exhaust Manifolds Gaskets Exhaust Pipes Catalytic Converters Resonators Mufflers Tail Pipes Flex Joints Heat Shields Exhaust Hangers Malfunctions can be caused by environmental damage, or even problems with the ignition or fuel systems. Catalytic converters can be damaged if the check engine light is flashing and the vehicle continues to be driven. The exhaus ... read more

Tempe Auto Repair: Check Engine Light

Tempe Auto Repair: Check Engine Light

When my check engine light comes on, I'm torn between utter panic and just wanting to ignore it and hope it goes away. How about you? How does it make you feel just thinking about it? It's understandable of course, because that same check engine light could be coming on for anything, from serious damage to your transmission all the way down to just a loose gas cap. "A loose gas cap?" you say. "There's a trouble code for that, seriously?" That's a really good question. There's a very common misconception that the trouble codes stored in your engine computer when your check engine light comes on will specifically identify a problem. It's really more like pointing to the symptoms of a problem. Take your temperature, for instance. Say it's 101 degrees. Your heat sensor, the thermometer, tells you your temperature is out of the norm ... read more

Paint-less Dent Removal - How Does It Work?

There's nothing like the let down of noticing the first dent on your new car. As one person put it, "it's not much fun to wax a dent". Getting it fixed is certainly an option, but maybe a pricey one. Or is it? Perhaps you've seen paint-less dent removal advertised or even offered in a local, exterior mall kiosk. Have you ever wondered how it works, and even if it works? I've wondered myself. My experiences of popping out a dent in many materials is that there's always some kind or remnant of the damage left behind. Not to mention we're usually talking metal here (sometimes plastic of some variety). Well, wonder no more how this is accomplished, all without removing any body parts from your car. Here's a beginners guide demonstrating the type of techniques and equipment used! And here are a few more examples

Tempe Auto Repair: Your Water Pump, the Unsung Hero of the Cooling System

Tempe Auto Repair: Your Water Pump, the Unsung Hero of the Cooling System

Water pumps. We don't think about them often, but they're a really important part of our vehicles. Let's take a step back. You see, the engine is cooled by a coolant, anti-freeze, mixed with water. This mixture circulates around your engine, absorbing some of the heat. The coolant then flows through the radiator, where air cools it down for the return trip back through the engine. The water pump is what drives this process. Cooling system problems are the number one mechanical failure. So, the water pump plays a pretty important role. You can't get very far without a water pump! Do water pumps just wear out? If so, what causes them to fail? After all those miles and years of pumping coolant, they simply wear out. You might notice a whining or grinding sound coming from the water pump, or maybe you'll see coolant leaking from the pump itself. Where's the water pump located? The exact location varies, depending on the vehicle. Some have the water pump attached to ... read more

The Changing World Of Professional Auto Technicians

The Changing World Of Professional Auto Technicians

For more than a century people have been using cars, trucks and other personal vehicles to transport themselves, other people and goods from one location to another. In fact, the motorized vehicle went from being a luxury to a necessity in many parts of the world where public transportation and other options are limited. As a result of this dependence, it's vital the automobiles on the road are kept in good repair. The work needed to do so has changed a great deal since the first cars hit the road, and is likely to continue evolving along with the rest of the industry. A few decades ago, there were many people who could perform simple repairs on their own vehicles. On top of that, "backyard mechanics" were common. These men could take care of the more complicated auto repair matters, including the engine and other complex issues. Of course, the majority of people would take their cars and trucks to a mechanic shop with licensed mechanics. Dealership shops were a great place f ... read more

How Do Flat Tire Repairs Work?

How Do Flat Tire Repairs Work?

A flat tire is one of the best ways to ruin your day. Not only do you have to jack up the car, take the flat tire off, and put the spare on (or call a service like AAA), you have to suffer the inconvenience of having the puncture repaired. But how does a tire repair work, is it effective and when is a tire considered to be irreparable? 1. Tire Repair There are basically three approaches to repairing a tire: - Plugs are used to repair holes in the tread of the tire, normally in the size and shape of the puncture. This should seal leaks from the outside of the tire but may be ineffective at sealing the inside or inner lining of the tire. This is the preferred method as it is quick, easy and inexpensive. - Seals are used on the inside of the tire. This means the tire needs to be dismounted, which is a time consuming task. However, seals are often more effective than plugs. On the other hand, they do not repair the tread or outside of the ti ... read more

Are Self Driving Cars Becoming Reality?

Are Self Driving Cars Becoming Reality?

Bloomberg is currently reporting, "Self-driving cars being planned by Google and global automakers may help counter slumping demand from younger customers by tapping the fastest-growing demographic in the world’s largest vehicle markets: the elderly." Baby Boomers are all quickly joining the elderly in both the US and abroad in strong markets like Japan, where an ever-increasing number of older drivers are being hurt and killed in auto accidents. In an industry conference last week GM and Toyota both emphasized as many as 90 percent of traffic accidents caused by human error, therefore a key benefit of the automation technology is boosting safety. Japan, the world’s fastest-aging major economy and the third-largest car market, is leading the accident trend: of the 4,411 people who died on the road in the country last year, more than half ... read more
