Vehicle emission testing has become ubiquitous in North America and for a good reason.  Clean air quality is important for the environment and all of us.  Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute. Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde.  Emissions control systems reduce these gases if they are working properly.  The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key.  So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong. Let's start on the easy one.  Your gas cap could be loose, allowing vapors to escape into the atmosphere.  The most common solution ... read more

There are a lot of things in life that CHICAGO residents have to do on a regular basis. We wash dishes every day, do our laundry and mow our lawns every week, and pay the bills every month. We should go to our CHICAGO dentist twice a year and see our doctor for a check-up once a year. When we don't stay on schedule with these routines, it can lead to embarrassing, painful or expensive consequences. Scheduled maintenance is also part of good vehicle care. CHICAGO drivers should take their vehicles in regularly for a good check-up. But many folks struggle to remember — or actually even ignore — this auto advice. When it comes to our vehicles, we're more likely to listen to, “If it ain't broke, don't fix it,” than, “An ounce of prevention is worth a pound of cure.” Yet it is the second adage that is the more applicable one.Regular brushing treatments prevent cavities. Filling a cavity prevents a more painful ... read more

It's happened to all of us.  We're driving down a highway at night and over a crest appears a car with its high beams blazing.  You are momentarily blinded, hoping the other driver will switch them to their low beam setting and restore your vision. Not only do we not appreciate being blinded, face it; we don’t want to be that other driver, either.  You know, the one who forgets to turn down their high beams. Why do we want high beams in the first place? They can improve safety when used correctly, giving drivers more reaction time since they can see farther down the road.  But research has found many drivers either don't use them or, when they do, they frequently forget to switch to low beams.  Enter the automatic high-beam dimmer. The quest for the perfect one began back in the 1950s, General Motors invented something it called the "Autronic Eye." It was a phototube which sat on the dashboard and turned down your beams when it saw other headlights.  ... read more

So it's up to us to make our cars a less appealing target and more of a challenge – hopefully sending potential thieves to look elsewhere.The National Insurance Crime Bureau recommends a layered approach to protecting vehicles: Common sense Visible and audible devices Immobilizing devices Tracking devices Let's review each of these. One is common sense; you would be surprised how many vehicles are stolen in Illinois where the keys were left in the ignition with the doors unlocked. Always take your keys and lock the doors. In fact, in some places it's against the law to leave a vehicle unattended with the keys in the ignition.And don't leave spare keys in the car or hide them outside – because a thief will find them.
