What is an In-Cabin Air Filter?

In-Cabin Air Filters help keep pollen, dust and other particles from reaching you and your passengers by filtering both incoming and re-circulating air inside your vehicle inside cabin. Most vehicle manufactures recommend periodic replacement of the In-Cabin Air Filter for optimal and fresh air quality inside of your vehicle. General rule of thumb would be, to check it at least once a year and replace at least every 30,000 miles. Who wants to breath molds, mildews, allergens, dust, pollens and other fowl contaminants?

What’s with the motor oil?

Motor oil is the lifeblood of your engine. It lubricates your entire engine and protects all of the internal moving parts. It also keeps your engine running cool because it acts as a coolant and, because it is a lubricant, it makes your engine run smoothly. There are varieties of grades, viscosities, and brands of oil available in the market place. However, choosing the right motor oil specification for your vehicle is critical to keep your vehicle performing at a highest level. It is recommended to only use manufacturers’ recommended oil viscosity and grade of oil specified. Using non-recommended motor oil will void vehicle warranty and may cause severe damage to the engine. Furthermore, changing your motor oil and oil filter at the manufacturers’ recommended interval is highly recommended for longevity of the engine.  We can do a Scottsdale oil change at our Bell Union Auto Service shop.

What can shift me to a higher level?

Did you stop and think about your Automatic Transmission fluid today? Of course, why not? We all know that Automatic Transmission Fluid (ATF) directly impacts how well your transmission shits and performs, right? Changing your ATF at regular schedule intervals will make your transmission last a long time, improve fuel mileage and keep your vehicle shifting smoothly on the road. On a manual transmission it is important to have your clutch cable or master cylinder fluid level checked regularly for optimal shifting and wear of clutch plate. Most manufacturers require a very specific ATF for their vehicle, so it is critical that you only use manufacturers required ATF only.

What’s in the timing?

Timing Belt or Chain. Timing belt or chains keeps your engine’s valves and pistons to work in synchronization. A broken timing belt will not only shut down your engine immediately, in some vehicles it may even result in a severe engine damage, thus causing expensive, unnecessary repairs. Having your timing belt inspected at the recommended intervals and replacing it at proper intervals can save you money, time and the inconvenience of getting stranded on the road. So, why take a chance when so much is at stake. Always insist on using a highest quality timing belt to minimize cracks and slippage. Higher quality belts will maximize durability, and maintain close tolerance for your timing gears for optimum performance of your engine. Timing is everything when it comes to fuel efficiency, and engine performance. Do not settle for less.

Filter them out!

Whether it’s motor oil, transmission oil, air or fuel they are vital to keep the environment clean from dirty impurities and contaminants. Filters can protect engine, transmission, fuel system, intake air, and the air you breath by filtering out impurities and contaminants. The higher the quality of the filter, the more impurities and contaminants it can remove from the environment it protects. Oil filters and some of fuel filters come with built in anti-drainback valves to maintain proper pressure. Of course, cheap filters will have inferior quality backflow valves which will not perform properly. Engine air filters are like lungs of your body. As you need to breath clean air, so does your engine. The job of your engine air filter is to remove most of dust and contaminants from the air as your engine aspires to the intake system. As the engine air filter gets clogged and restricted the fuel mileage of your car goes down and your vehicles performance goes down.

Will you stop for me?

Brakes are essential to safely stopping your vehicle. When you apply your feet to the brake pedal your brake pads or shoes apply pressure to the brake rotors or drum. Through the friction between the pads and rotors or shoes and drums, your vehicle eventually comes to stop. However, over time these parts wear down to a point where you need to repair them to maintain the performance as intended. There is more than just replacing these brake parts to the remedy. An experienced, qualified and certified technician can determine exactly what replacement parts will work best for your need and keep the brakes working the way it was designed and specified by the vehicle manufacturer. Experience and knowledge of the technician will keep your vehicle brake parts from premature wear, annoying squeaks, vehicle pulling and other weird sensations from your steering wheel and brake pedal pulsations. In addition to the mechanical parts of the brakes there are many fluid dynamic components to your brake system. There are Master Cylinder, ABS System, Disc Calipers, Wheel Cylinders, brake hoses and lines, and of-course there is Brake Fluid. Depending on your vehicle design, every vehicle uses different specifications for the Brake fluid. There are Dot 3, Dot 4, Dot 5,and some manufacturers require a very specific Brake fluid such as a mineral base or other exotic blends. To determine all these different specifications and requirements, only a highly experienced technician can repair and service your brakes properly.

What is black and round and never complains?

Tires, yes tires. Tires are vital part of your vehicle, it is the final part of your vehicle that move your vehicle and stop your car. Tires impact your vehicle performance, fuel economy, ride comfort and safety of you and your passengers. As the miles add-up on your vehicle normal wear of tires occurs, gradually diminishing the quality of your drive and safety, especially in wet driving conditions. The National Transportation Safety Board (NTSB) recommends the thread-dept of your tires to be at least 2/32nd of an inch at the lowest point of the tire to be safe. Also due to the cracks and dryness of rubber over the years, it is recommended to replace your tires if they are older than 6 years. It is also recommended to check your tire air pressure at-least once a month. Manufactures recommended air pressure as noted at drive side door-jam where other Vehicle Identification Number (VIN#)’s are.

How is your Driving?

Your driving may be perfect, but your vehicle may have an attitude. Is your vehicle steering wheel pointing in the correct direction? Is your vehicle vibrating at different speeds? Are your tires wearing properly? All these questions and more can be answered by a properly trained and experienced technician. Having your tires air pressure checked and rotated at regular intervals, and checking the wearing condition of tires can increase your vehicle’s comfort, fuel mileage and the safety of you and your family. Furthermore, an improperly balanced and aligned vehicle could wear your tires thus causing unnecessary expenses.

Are you in control?

You can rate your ride by observing the following motions of your vehicle: braking nose dive, body roll, ride harshness, acceleration squat, traction loss when wet, bottom-out over bumps, swerving while going around the bend, vehicle bouncing while driving and tires cupping and unusual tire wear. Vehicle stability means being able to stop, turn, and swerve at exactly the moment and in the amount you need. Your shocks and struts react to every wheel and body movement, every bump and every corner. Shocks and struts keep your vehicle stable and you in control. If your vehicle is over 50,000 miles or more it may have worn shock or struts. Worn shocks or struts can decrease your vehicles stopping distance, cause the front-end of your vehicle to nose dive and cause premature tire wear.

Are you in-charge?

Is your car battery in-charge? A battery’s performance abruptly drops just before it fails to start the vehicle. Before that abrupt drop, the battery may start the vehicle but its performance has begun to decline. This condition is called marginal state. Extreme heat or cold could cause a marginal battery to completely fail. Where you live affects your battery’s life expectancy. Phoenix, Arizona is one of these extreme heat climates. If your battery is 3-years or older you may experience a battery failure in Phoenix, Arizona. It is a good idea to have your battery checked if you have experienced following: battery indicator light-on on your dashboard, lights or stereo have been left on for a long duration, your vehicle has been jump-started recently, your lights dim when the A/C is on, the battery cable or post is corroded. Remember, batteries never die at your convenience. Early detection is the key, we can perform a diagnosis of your battery in few minutes.

Am I Hot or Cool?

It is another beautiful day here in Phoenix. The outside temperature is reaching 120 degrees and inside of your vehicle’s ambient temperature is reaching almost to a kitchen oven temperature. Are you cool as a cucumber or hotter than roasted jalapeno pepper? Well, a properly operating Air-Conditioning (A/C) system in your vehicle could give you all the comfort inside of your vehicle as long as it is working properly. Your Air-Conditioning System has many different components that work together to keep that cool air flowing inside your car and keep you cool and comfortable. A/C systems consist of: A/C Compressor, Clutch & Field, Condenser, Condenser Fan, Evaporator, Cabin Fans, Vents, Expansion Valve or Tube, Receiver Dryer, Pressure Sensors & Switches, High & Low Pressure Hoses, Seals, Refrigerant and oil, Control Valves and Switches and many other components. To determine a A/C problem with your vehicle a qualified and experienced technician must check all these components to diagnose your A/C System. There are many cheap and inferior parts out-there, of-course they would not work as efficiently as a higher quality components. Quality components will provide you with better cooling of inside temperature, better gas mileage, less noise and vibration, less leakage, proper fit and many other benefits.

I need more power Scotty!

The Fuel Injection System is an intricate part of modern internal combustion engine. Fuel is distributed to each of the cylinders of the engine directly or indirectly depending upon the design of your engine. Of-course the carburators went-out with the disco-balls and bell bottom pants. The fuel injection system is a much more efficient system than carburators, because it could deliver more precise air-to-fuel mixture for proper power and economy to the vehicle. However, over time these injection systems get gummed-up in the fuel injectors, intake ports, intake chambers, and even in the combustion chambers. The build up of these dirty deposits can cause increased exhaust emissions, reduced fuel economy, driveability problems, engine knocking and loss of engine power. If you vehicle is over 50,000 miles, it is recommended to have fuel injection system cleaned and performance-checked. You would be amazed at the new car feeling as you notice an increase in fuel mileage and the performance of your engine.
