Your parents probably taught you to have common sense. When it comes to your vehicle, common scents can also come in handy. Different smells may tell you about some conditions in your vehicle that need attention. For example, you know what rotten eggs smell like. If you smell them around your vehicle, it means sulfur can't be far away. Here's a surprising fact: Gasoline has a little sulfur in it. There's a device in your exhaust system that's supposed to convert it to something that doesn't pollute the atmosphere. That device is a catalytic converter. If you are smelling rotten eggs, maybe your catalytic converter is wearing out. But it could also be a problem with your fuel injectors. Either way, something's rotten that should be repaired. Ever smell something sweet around your vehicle, maybe a little like pancake syrup? If you sniff out a little sweetness just when your engine is warming up or after you shut off your engine, you might be smelling some co ... read more

There's one fluid in your car you are always careful to keep at a certain level: the fuel. If you don't have fuel, you're not going anywhere. Your vehicle has other fluids which are vitally important to proper and safe operation, too. So, here's a "level" headed approach to those "other" fluids. Engine oil. This one's probably the most important fluid to maintain at the proper level. Without enough oil, you'll wear out your engine prematurely. Sometimes vehicles have warning lights on the dash that will tell you to get your oil checked. Don't ignore that one; get it checked immediately. Certainly don't go on a long trip at high speeds with your oil level low. Oh, and it's not good to have too much oil in, either. Our pros at Walker Automotive can advise you on oil levels and tell if you if you should be concerned about abnormal fluctuations. Windshield washer fluid. OK, this is one you probably know about. You certainly miss it when it ru ... read more

Nobody has to tell you that computers are a part of so many things in our lives. Smartphones, kitchen appliances, vacuum cleaners, televisions. You name it—it has a computer in it. And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer. But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems. There are various sensors throughout modern vehicles that measure thousands of data points. When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car. It displays certain codes that help technicians track down the culprit. But it's not just the diagnostics that are computerized. Everything from your vehi ... read more

So your vehicle won't start. What's the first thing that comes to mind? Battery dead? Starter motor worn out? Out of gas? Well, those are all reasons that make sense. But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it. Here's how that works. You have lots of computers in your vehicle. They need to know the status of things so there are several sensors monitoring various things going on. These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel. They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly. Here's an example of a sensor doing its job. Your engine needs oil to lubric ... read more
