Archive for July 2024Differential Essential (Differential Fluid Exchange)Posted July 28, 2024 4:00 AMWhat's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels. The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn). Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there. (Your vehicle may have more than one differential in it depending on the drivetrain.) As you can imagine, it's important that the lubricant in those differentials do its job. Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down. So, it's important to have the differential fluid exchanged every so often. Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km-100,000km. Regular exchange of differential fluid can reduce premature wear of the gears inside. Scheduled maintenance goes a long way to preventing differential problems, but sometimes when they begin to fail, you may hear the vehicle sounding a little louder than usual where the differentials are located. When it comes to changing the differential fluid, some have a drain plug in them. Others require the entire cover to be removed to drain the fluid. There are often gaskets that must be changed at the same time to make sure there are no leaks. Arizona Auto and Radiator Repair No Fueling Around (Fuel Filter Replacement)Posted July 21, 2024 4:00 AMA driver called in to the shop the other day saying his European sports sedan had an odd problem. He was driving when his car started to slow down. Applying more throttle didn't help. He pulled over to the side of the road, shut the engine off and waited a few minutes before starting it up again. It ran fine… for a couple of minutes. Then the same thing happened. He was able to finally get home by stopping and restarting, and he was calling to see if we could take a look at it. Turned out it was one of his car's fuel filters that choked up with debris so badly that enough fuel couldn't get through it. When he stopped the car, enough fuel could flow through the unpressurized fuel line to supply enough fuel for a couple of minutes when he restarted his car. But then the pressure would cause things to clog again. There are other symptoms that point to a failing fuel filter. Perhaps your engine misfires, your vehicle is hard to start, or your fuel pump starts making odd noises. Many vehicles have at least two fuel filters. One is a strainer that is part of the fuel pump in the fuel tank, and the other is in the main fuel line. Your vehicle's manufacturer recommends how often yours should be changed, but your driving habits and environment (such as dirty or dusty conditions) may mean yours will have to be replaced more often. The technician will also look to see if your vehicle might have another problem that's causing your fuel filter to fail more frequently than normal, such as corrosion in the fuel tank. Your engine needs fuel to run. Maintain the health of your fuel system and that will help keep you on the road to your destination. Arizona Auto and Radiator Repair Timing is Everything (Timing Belt)Posted July 14, 2024 4:01 AMTalk about exquisite choreography; it happens under the hood of your vehicle every time you take a drive. Your engine’s many complex parts must work exactly together. One key is a part called a timing belt, which enables the synchronizing of two of your engine’s components, the camshaft, and the crankshaft. The timing belt coordinates the valves in your engine to open and close at the appropriate time to get exhaust out of the engine’s cylinders. Timing belts may also power the water pump and the oil pump. The belt is made of rubber. Some engines use a timing chain (made of metal). Your vehicle’s manufacturer recommends an interval after which you should have your timing belt or chain replaced, and that service should be part of your vehicle’s regular maintenance. It’s always better to replace it before it breaks rather than after. After all, if your timing belt breaks while you’re driving down the road, it throws off the whole sync of engine parts and can cause major damage to the type of engines most commonly used in vehicles today. It's also important to remember that a timing belt is made of rubber, and rubber deteriorates with time, no matter how much use it gets. Have us look at your timing belt to see if it’s time to get it replaced. Here are some signs to look for that will let you know if your timing belt is failing. You might have trouble starting your vehicle, it may misfire or black smoke may come out the tailpipe. If you notice any of those symptoms, bring your vehicle in and have us take a look right away. When it comes to your engine, timing is everything. Arizona Auto and Radiator Repair The ?Man-Made? Engine Oil (Synthetic Oil Change)Posted July 7, 2024 4:01 AMIf you own a newer vehicle, your vehicle’s manufacturer may require that it use synthetic oil instead of conventional oil. Synthetic oils are more stable, don’t break down as easily, and provide better engine protection than conventional oil. All those things can prolong the life of your engine and help it run better. Imagine the damage that could happen to your engine as it operates at high speeds and very hot temperatures. Oil reduces the friction between the metal parts. That’s why it’s important that it maintains its lubricating properties for a long time, which synthetic oil does better than conventional oil. Clean oil is better than dirty oil because it has fewer impurities. Synthetic oil is purer because of how it’s formulated and manufactured. Plus, as the outside temperatures change, the ability of oil to operate in those conditions is important. It’s not only newer vehicles that can benefit from synthetic oil. If you have an older vehicle, synthetic oil may offer superior lubricating than conventional. Our technicians can advise you what’s the best oil for your vehicle and how often you need to change it, which may vary from the owner’s manual recommendations. You might find you’re able to change your oil less frequently than you used to with conventional oil. Yes, synthetic oil is more expensive than conventional, so let us help you decide whether its advantages are worth the difference in price. Arizona Auto and Radiator Repair | ||

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
