Archive for June 2024Command Performance (Engine Air Filter)Posted June 30, 2024 4:01 AMThe internal combustion engine in your vehicle counts on two things that mix together to be burned in the engine for power: fuel and air. Both are important, of course. If you run out of fuel, your engine won’t run at all. Since there’s plenty of air around, you won’t run out of air, but you could feel your vehicle’s performance suffer if the engine air filter starts to get clogged. It's important that the air that enters your engine be free of dirt, dust, and debris to prevent damage to internal components. That’s where the engine air filter comes in. It prevents those particles from entering the engine, an important job that most people just take for granted. After a while, your air filter will get dirty, which results in less air reaching the engine. Modern fuel injected engines can adjust the amount of gas to mix with the air that is getting in, so your fuel economy won’t change significantly. What will change is how well the engine performs, its acceleration. In one test, a US Department of Energy study showed that a dirty air filter reduced a vehicle’s get-up-and-go by as much as 11 percent. The company that made your vehicle includes guidelines in your owner’s manual on how frequently that filter should be changed, and doing so will maintain your engine’s performance. If you drive in dusty, dirty areas or those with a lot of industrial pollution, we recommend you replace the engine air filter more frequently than the manufacturer’s recommendations. When you bring your vehicle to us for regular maintenance, we will routinely check several components, including your engine air filter, and recommend a change when we see signs it’s needed. It’s good for your engine, and you’ll enjoy the performance you expect. Arizona Auto and Radiator Repair Strutting Your Stuff (Shocks and Struts)Posted June 23, 2024 4:01 AMEver wonder how your vehicle is able to move over bumps, potholes and other irregularities in the road and you hardly feel a vibration in the cabin? It’s your shocks and struts doing the hard work along with the rest of your suspension and tires. They keep the ride smooth and are important for your vehicle’s safe operation. So, how do you know when your shocks and struts are wearing out? One way is to look at the surface of your tire (where the rubber meets the road—where the tread is). You might see some little indentations in certain spots, known as tire cupping. If your vehicle takes longer to stop than it used to, takes a dive when you hit the brake pedal or bottoms out (scrapes) on a big bump in the road, that’s another sign, as are loud, odd noises. You may also notice your vehicle sways more than it used to. Every once in a while, look around at your shocks to see what shape things are in. If you see the rubber cover cracked or worn out or see a fluid outside your shocks, those are signs to bring your vehicle in to us so we can see what’s going on. Since shocks and struts contribute to the safe operation of your vehicle, this service is important. Shocks and struts are what help your tires stay in close contact with the road and help stabilize your vehicle. They also help electronic safety systems work properly, including anti-lock braking, stability control, and collision avoidance. Bad shocks and struts are just going to get worse with time. It's best to have regular maintenance done before anything goes wrong with your struts and shocks. Your vehicle’s manufacturer has guidelines for how long those intervals are. If you do start to see some of the warning signs, head on over so we can evaluate any problems. We’ll replace the parts your vehicle needs and have you strutting your stuff once again. Arizona Auto and Radiator Repair A Bright Spark (Ignition Coil Replacement)Posted June 16, 2024 4:01 AMEver wonder how your vehicle’s engine is able to take the 12-volts from its battery and ramp that up to as high as the tens of thousands of volts it takes to fire its spark plugs? The secret is something called an ignition coil. Most newer vehicles have an ignition coil at each cylinder, but older ones have a coil that serves all of the spark plugs. There are telltale signs that you have an ignition coil problem. As you might expect, one symptom is it’s hard to start your engine or it won’t start at all. If your engine is misfiring or not running smoothly or you see the Check Engine light come on, those all could point to an ignition coil failure. Several things can contribute to ignition coil trouble in addition to normal wear and tear. Moisture and dirt may have gotten inside the coil, plus the heat and vibration of your engine over time can contribute to them going bad. Bad spark plugs or plug wires can also be a cause. While ignition coils can last 100,000 miles/160,000 km, depending on how you drive and in what conditions. If you start noticing some of the signs and symptoms just described, it’s a good idea to schedule a visit to see us so a technician can diagnose what’s wrong. Driving too long with an engine misfiring can damage your catalytic converter, and that can be expensive to replace. A technician will thoroughly check your ignition system and determine where the failure is. If it’s only one coil that’s bad, it may be the only thing that will need replacing. If your vehicle has a distributor, it may also need to be replaced. Properly-working ignition coils will help your vehicle operate at its best and help prevent future engine damage. Arizona Auto and Radiator Repair Flat Tire? Three?s the Charm (Tire Repair)Posted June 9, 2024 4:01 AMFor most drivers, at some point you’re going to have a flat tire. Depending on how it was damaged, it may have to be replaced. But sometimes, a repair will do the trick, as long as the puncture isn’t on the sidewall and the hole is smaller than ¼ inch/6.35mm in diameter. Here are the three common ways your tire can be fixed. One way is to put a plug in the hole. Since most tires are damaged by running over sharp objects such as screws and nails, the small hole from which the air is escaping is on the part of the tire that touches the road. If it’s in the sidewall, it most likely can’t be fixed. In the plug method, a technician inserets a rubber plug. It is covered with some sticky, gluey stuff, and is pushed into the hole from the outside. That plugs the hole and stays in place, thanks to the glue. Friction from driving heats it up and seals the deal. Another method is to patch the hole. For this, your tire has to first be taken off the vehicle, then off the rim so the technician can get access to the inside. There, they’ll clean the inside surface around the hole and apply a rubber patch with an adhesive on it. This type of patch works well, and because of the extra steps and complexity, costs more than having your tire plugged. There’s also a combination of those methods just described, the plug-patch. It is, in essence, a type of patch with glue on it that has a plug sticking out of it. The plug is inserted into the tire from the inside and pulled through the hole from the outside, drawing the attached patch tight against the tire’s inside surface. The last two methods can’t be used if the hole is near another repair or the sidewall. The good news is if it’s fixed properly, your repaired tire should give you good service. Arizona Auto and Radiator Repair Clean Machine (Fuel and Air Induction Cleaning)Posted June 2, 2024 4:01 AMAs your vehicle ages, its performance isn’t quite what it used to be, but many of us never notice the change because it’s gradual. So here are a few questions to ask yourself. Does your vehicle feel like it doesn’t have the pep that it used to? Have you noticed your fuel economy isn’t quite as good as it once was? Does it idle roughly or is it hard to start? Do you hear the engine knocking? Has it recently failed an emissions test? All of those can be signs that your fuel and air induction systems are dirty and need cleaning. Your fuel system takes gasoline from the tank to the engine’s combustion chambers where fuel injectors spray fuel that mixes with air and is ignited by spark plugs. Black carbon deposits eventually can build up, obstructing fuel flow and diminishing your engine’s performance and fuel efficiency. The air induction system is what allows air to go into the engine’s combustion chamber. Getting the proper air flow is necessary for you to quickly start your vehicle, accelerate, and perform the way it should and idle smoothly when you’re standing still. Like the fuel system, your air induction system can get blocked up with deposits and other contaminants. A professional fuel and air induction cleaning can help restore your performance and fuel economy, especially when you are experiencing problems. A technician will use specialized chemicals that can remove the carbon buildup. In extreme cases, they will remove the fuel injectors and clean them with specialized tools. After cleaning, you may notice how much more pep your vehicle has and how smoothly it runs. Keep your fuel and air induction systems clean and enjoy your vehicle’s performance improvements.

AZ Auto and Radiator performed a thorough check of my vehicle and found some issues that I suspected were present, but were never diagnosed by another local auto business. The owner took the time to show me (on the vehicle) what he recommended and why. Professional, friendly service, and they didn't pressure me to have everything fixed immediately. Highly recommended!~ Susanne, Sierra Vista AZ
