Thom's Four Wheel Drive

One might say the most challenging part of being an automotive service technician at Thom's Four Wheel Drive is diagnosing a problem before it can be fixed.Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it's challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it's not something obvious, it's easy for the customer to focus on the fixing and not the diagnosing.Let us at Thom's Four Wheel Drive introduce you to something we'll call 'Customer Detective Work' –  helping your technician find clues to what's wrong.We start with the detective basics: What, Where and When. Play along with me; You come in to Thom's Four Wheel Drive and your car is making a funny sound... Q: Where's the sound? A: Around the right front wheel. Q: What kind of sound?

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.
