Archive for May 2022Why You Have an O2 Sensor (Oxygen Sensor)Posted May 29, 2022 10:12 AMIf someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent. But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust. If there's too much, it means there's a problem with the mixture of fuel and air. The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency. It does this constantly. Many vehicles have multiple oxygen sensors. Some have one close to the engine, another close to the muffler. Two measurements are better than one since they allow readings to be more accurate. You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail. One thing that can damage them is contamination from bad fuel. The sensors can simply wear out, though they usually last a long time. It's not unusual for an oxygen sensor to last 100,000 miles/160,000 km. One more thing that can cause an oxygen sensor to fail is residue from an engine that's burning oil. Plus contaminants from the road like salt can also cause problems. Here are some signs that your oxygen sensors might be failing.
Head to your service facility and tell your advisor what symptoms your vehicle is experiencing. They have the equipment and training to track down the issue. Note that simply replacing the oxygen sensor is often not enough since it doesn't get to the root of the problem; other repairs may be needed. So make sure your oxygen sensors are working the way they should be. Oh, and back to the question of what gas makes up most of the Earth's air? It's nitrogen, which comprises 78 percent of the air we—and our engines—breathe. Auto Authority LLC Cool Running (Water Pump)Posted May 15, 2022 11:37 AMYour vehicle is like you in a way. When it gets hot, it needs to be cooled down. And one of the key parts to keeping it cool is the water pump. Now, that's a bit of a misnomer. It IS a pump, but it's pumping coolant, not pure water. Cooling off your engine is vital since it builds up heat when it creates power by burning fuel. Your water pump acts as a way to recirculate that coolant. It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat. Cooled off, the coolant is recycled through the water pump to start the journey again. The water pump works by taking mechanical power from the engine, usually from a belt. Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job. Here are some things to look for that will signal problems with your water pump. If your heat gauge is erratic or showing a much higher than normal temperature, that could be a sign of trouble. Another is if you hear a whine under the hood. And if that gets louder when you go faster, get it checked right away. You may see steam coming out from under the hood or coolant may be leaking. These signs signal that it's time for you to have a technician check to see where the problem is. Some water pumps are powered by a timing belt. If your vehicle has that design and your timing belt is due for replacement, sometimes it's a good idea to replace the water pump too, even if it's working properly. That's because the labor to replace the timing belt can be expensive and it may be wise to proactively take care of the water pump while it's disassembled. Your service advisor will explain the options available and offer the best path to keeping your water pump doing its job. Your engine's life depends on it. Auto Authority LLC That Vexing Vapor Venting (Vapor Coming out of Vents)Posted May 8, 2022 7:48 AMYou may have noticed sometimes on a hot and humid day, vapor will come out of your vehicle's vents when you have the air conditioning on. Is that something to be concerned about? Well, it depends. Sometimes that steam or vapor can be caused by water accumulating in the vent system after it has condensed. And sometimes water can pool at the bottom of a vent. When you turn on the blower mower, the air hits the water and may create steam or vapor that you can see in the cabin. One thing to check is if that vapor smells like anything. If it doesn't, that's a good sign. You may be able to run the fan for a while and the issue may just go away when things dry out. But moisture collecting in the ventilation hoses in a hot vehicle may be a breeding ground for mold, and that can have health consequences. There's another possibility. Ventilation systems often have drains to get rid of any accumulated water, and debris can sometimes clog them. A technician can clean out those drains and you'll be back in business. One thing to nose around for is a sweet smell coming out of your vents. Sometimes the heater core (a component of your vehicle's heater system) can develop very tiny holes. That sweet smell may be coolant that's been vaporized by those tiny holes entering your cabin. It's always a good thing to mention to your service advisor any abnormality you're seeing—or smelling—in your vehicle. By venting a little about your vents, a technician can get to the bottom of the problem before it starts "clouding" the issue. Auto Authority LLC That Squeal is Telling You Something (What Causes Squealing While Steering)Posted May 1, 2022 9:16 AMIf you hear a squealing noise when you turn your vehicle, it's trying to tell you something is wrong. After all, it never made that noise before, right? The sound you hear may becoming from a few sources. Let's take a look (or a listen) to some of the possibilities. First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically. For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. Sometimes that fluid gets low because of a leak or some other problem. The belt could wear out and start squeaking, and you might feel the steering start to become harder. Your service repair facility can figure out the problem and offer some solutions. Another cause could be in your suspension. Some components may not be getting lubricated like they should. Or you may be hearing your tires squealing when you are turning. Properly working steering is a huge safety factor for your vehicle's operation. Your steering affects handling, vital to your well-being as well as that of drivers around you. So take your vehicle over to your repair facility and have it checked out. You'll be doing everyone on the road—including yourself—a big favor by listening to your vehicle. When it comes to steering, silence really is golden. Get that squealing repaired and get back to safe driving. Auto Authority LLC Beginning to See the Light (Check Engine Light Diagnostics)Posted April 24, 2022 11:17 AMIt's a light many drivers fear they'll see turn on at the most inopportune time. It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine. The truth is that Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine. Don't ignore it because it's there to help you avoid an expensive repair it is designed to alert you to, to tell you something's not quite right. Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light. If it's flashing, that could be serious. Look at some of the other warning lights or gauges such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right away. In that case, if you can, safely pull off the road and shut the vehicle down. If your vehicle loses power and the Check Engine light is on, try not to push the demands you are making on the engine, such as towing or accelerating hard. Simply put, a flashing Check Engine light should be checked out by a professional as soon as possible. If the Check Engine light is on steadily, manufacturers say it means there's a problem, but it probably doesn't require immediate service. The system is designed to remember the problem it found and store it (as a code) so it can be retrieved later. When you do bring your vehicle in to have us see what's behind the Check Engine light coming on, we’ll hook your vehicle up to a diagnostics tool that can reveal the clues the engine's computers have stored. It takes a trained technician to understand those clues, like a doctor who can interpret a patient's symptoms and come up with the correct diagnosis. Some newer vehicles can even be checked remotely. Once we figure out the problem and repair it, you'll be back on the road again. It's nice to know the Check Engine light is your sentry, standing by to alert you the next time you begin to "see the light." Auto Authority LLC What's in a Number? (What Tire Numbers Mean)Posted April 17, 2022 9:59 AMYou've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information. There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on. Let's check out this example found on an SUV: P245/70R17 108T. The first letter, P, means it's intended for passenger vehicles. If there's no letter, it means it's a metric tire. If there's an LT at the beginning or end that means a tire designed for light trucks. Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall. The number that follows in our example, 70, means the height of the tire is 70% of its width. The letter after that in our example, R, describes the type of tire (on this vehicle, radial). Following that is the diameter in inches, in our SUV example, 17 inches. How much load the tires' sidewalls are designed to take is what that next number is all about (108 in our example). The higher the load index, the more weight the sidewalls can take. And the last letter is the speed rating of the tire, in our example, T. The further along in the alphabet that letter is, the higher its speed rating. So now you know what those letters and numbers mean. But why are they important? When you are getting ready to replace those tires, those numbers are telling you what the original equipment was when your vehicle was new. Sticking with the same rated tires is always a good idea. If you don't know what you're doing, trying different sized tires and wheels can cause real issues when it comes to performance and safety, considering all the computerized systems now found on vehicles. When in doubt, consult your service advisor when it comes to buying new tires. He or she knows what those tire numbers and letters mean… and a whole lot more. Auto Authority LLC Bad Vibes (Disc brake rotor problems)Posted April 10, 2022 11:18 AMIf you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes. Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes. The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers. If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that are what create the friction and stop your vehicle. Here’s why disc brakes need regular maintenance. Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs. Your brakes may have one of the 3 “S” sounds: squeaking, squealing, or scraping. The sound is usually the first sign of brake pad wear which can lead to rotor damage. Soon you may notice a pulsating or vibration when you brake. That’s because your once smooth and straight rotor disc is warping from the heat generated from friction. Or it may be due to wear. Eventually, your brakes will take a longer distance to stop your vehicle, and the rotors can have grooves carved into them. When you start noticing any of these signs, it’s a good idea to have them inspected by a trained technician. They will measure the rotor thickness, check wear patterns for grooves and heat discoloration, and see how much of the brake pads remain. They will also check to make sure all brake components are moving freely, check your brake fluid, and look for corrosion. Most vehicle manufacturers require worn or damaged rotors to be replaced, not resurfaced. It’s all part of a complete brake job, replacing pads and the brake hardware parts along with the rotors. It reduces the chance of premature failure. How often you will need your brakes serviced depends on the manufacturer’s recommendations, your driving habits, and the environment you live in. Your service facility can recommend the best replacement parts based on those factors. Regular maintenance and attention are vital for keeping your brakes performing like they are designed to. Remember, your brakes are your vehicle’s most important safety feature. Auto Authority LLC Emergency! (Vehicle Emergency items)Posted April 3, 2022 10:59 AM"I never expected it could happen to me." Countless drivers have said that after they've had an emergency turn their lives upside down. So before that happens to you, let's thinking about planning ahead for an emergency with a few things you should keep in your vehicle.
Other things like basic tools, a first aid kit, a space blanket and jumper cables are also good ideas. Many service repair facilities offer these items for sale, and you can ask your service advisor for suggestions. While it's fresh in your mind, plan a shopping trip and put together your own emergency kit now. Sure, you can put it off, but you may find yourself stuck in a difficult situation, saying to yourself, "Only if…" Auto Authority LLC The Part You've Never Seen (Flat Tires and Solutions)Posted March 27, 2022 12:04 PMThey say your vehicle has one, but you've never seen it. And you might not even know it if you stumbled on it accidentally. We're talking about the jack, that tool that allows you to lift one corner of the vehicle up so someone can change a flat tire. So you say you'd never try to change a flat anyway, so you don't care where it is. But one day, you may find yourself in a spot where you're stranded with no cell service and you'll need to at least know the basics of what to do. Well, here's the ironic part. Many of today's vehicles don't even have jacks and spares! Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor. If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it. Hopefully you'll be able to call roadside assistance and they can take care of things, but circumstances may prevent help from coming for a long time. The next time you're here at Auto Authority LLC for routine maintenance, ask one of our pros to show you the basics of your vehicle's flat tire tools. Consider watching an online video, too; there are plenty out there and may be specific to your make and model. Some vehicles have a space-saving spare, a smaller one that is meant to get you on the road long enough to find a place to have it repaired or replaced. Those vehicles will also have a jack. Then there are vehicles that have a full-size spare tire and a jack. Again, you may prefer to call roadside assistance, but if no one is available or reachable (which is sometimes the case in a major storm), you may have to fix your own flat. Some drivers do a "dry run" of changing a tire in their driveway during daylight hours so they at least know where the jack and spare are and how to use them. Our service experts may be able to help you locate each part and give you some tips. And again, there are many videos online that can show you the fundamentals of jacking your make and model of vehicle. Nobody relishes a flat tire. You may be lucky and never have to change one. But in this case, a little knowledge is better than no knowledge at all. In the unlikely case you are stranded at the side of a highway at night in the middle of the rain with no cell service, you'll at least be one step ahead.
A Turn for the Worse (Using Turn Signals)Posted March 20, 2022 11:54 AMDistracted driving is bad, you know that. Daydreaming, talking on the cell phone, putting your makeup on in the rear view mirror. All bad. But there's something else that causes more than twice as many accidents, according to a recent study. And that's people who don't use their turn signals. Maybe you're one of them. One survey said nearly a quarter of drivers were just too lazy to use their turn signals. Others said they didn't use them because they weren't really necessary. Traffic laws may dictate otherwise, but statistics show police don't write that many tickets for turn signal violations. You may have encountered the driver who cuts into your lane without signaling a change. Often, that person does it deliberately to catch you off guard so you won't invade his or her space. And when it comes to young drivers using turn signals, one insurance company survey showed more than two-thirds of those they talked to admitted it wasn't their regular practice. Knowing that, you may wonder why you should use your turn signal. The reason is simple. It lets other drivers know what you plan to do. Driving it tricky enough with all the moving parts on the road. The more you know what other people are doing, the more you can prepare for that with the way you drive. How many times have you seen someone turn left without putting their turn signal on? That's a leading cause of rear-end accidents. Not only does using your turn signal promote safety, it also shows courtesy to other drivers. There are some drivers who don't use turn signals because their turn signals don't work. What a lousy excuse! All of the safety equipment in your vehicle should be working; if it isn't, head over to your repair facility. Often it's as simple as a burned out bulb or a broken wire. Finally, the number one reported reason for not using a turn signal is that drivers just forget to do it. (And the ones who DO use their turn signals and forget they're on? We won't even go there.) Engineers put turn signals on vehicles for a reason. They help drivers communicate with other drivers. Using them could save accidents… and lives.
