If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents.  There are many things that can cause a vehicle to give off a gasoline odor.  One of the easiest to track down is the gas cap.  It could be missing or it doesn't seal well any more (they do wear out).  That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis. Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal).  They can leak gasoline, too. It's always a good idea to check the garage floor for any gasoline puddles.  Note the location of the puddle in relation to ... read more

You know your body temperature is supposed to be 98.6 degrees F, 37 degrees C.  Your vehicle has a normal temperature, too, and if you pay attention to it, that can save you some big headaches down the road. Many vehicles have a temperature gauge on the dash that takes the temperature of the engine's coolant.  Some have a thermometer symbol, some read C-H (cold to hot). Many will have a red zone that shows when water temperature is getting into the danger zone.  Others are digital and have a red warning light that signals overheating.  And some vehicles have a light that goes on when the engine temperature is out of the normal range. If your vehicle has a gauge, pay attention to it.  If you need help locating it, ask one of our Thom's Four Wheel Drive experts to give you a quick explanation.  Chances are when the vehicle has been running for 15 minutes or more, the temperature gauge will settle into its own "normal" zone, often just below the midway point ... read more

Have you ever gone to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That's why they tune up together.Now this is no surprise; I'm going to relate the orchestra to your vehicle. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.We call this... (ta-da) a tune-up. When an orchestra's out of tune you get a bad concert. When your vehicle's out of tune you get bad performance and bad fuel economy.So check your owner's manual for recommended tune-up intervals. Or ask your CHICAGO service advisor at Thom's Four Wheel Drive what he thinks....Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

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

Every car in CHICAGO, Illinois, is at risk for theft. 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.

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. CHICAGO drivers would be wise to park in well-lit areas that have a lot of foot traffic. If possible, park near the end ... read more

Wiper blades are critically important to CHICAGO drivers for good driving visibility and safety. When it’s time to replace your wiper blades, there are a number of different wiper blade designs and grades. CHICAGO drivers should always use at least the design or grade that came with their vehicle. If you live in Illinois where there is a lot of wet weather, flying insects, or you do a lot of highway driving, you may want to upgrade to a more advanced design or premium quality wiper blade.

There are some boots that don't come in a shoe box and aren't worn on your feet.  They are called axle or CV boots, and they can be important parts for many vehicles. That CV stands for constant velocity.  CV axles are mainly used in front-wheel drive and all-wheel drive vehicles. They're also used in some rear-wheel drive vehicles with independent suspensions.  They have two CV joints, one inner and one outer, placed between the axle and the drive wheels.  That way the vehicle's engine power can drive the wheels, no matter what angle they are.  They also adjust for the different speeds wheels turn as they go around corners.  Because roads are full of all sorts of hazards (dirt, oil, water, grime), these CV joints need to be protected.  They also have grease in them to keep the bearings moving smoothly.  That's the job of the rubber boots that are supposed to keep that debris out.  These CV or axle boots are made of rubber or plastic and usu ... read more

Hello, CHICAGO residents. Let's talk fuel filters. Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the engine.CHICAGO auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be se ... read more
