How Often Should I Replace My Car's Battery?

Your car's alternator and battery are two essential components that work together to power the various electrical systems in your vehicle. While the alternator generates electricity to keep the battery charged, the battery stores that electricity and provides the initial power needed to start your car. Understanding how these two components function in tandem is key to maintaining a reliable and efficient electrical system in your vehicle. The alternator is responsible for converting mechanical energy from the engine into electrical energy to power the vehicle's electrical systems and keep the battery charged. It works by producing alternating current (AC) that is then converted to direct current (DC) to charge the battery and supply electricity to the lights, radio, air conditioning, and other accessories in the car. Without a functioning alternator, the battery would quickly run out of power, causing the vehicle to stall and the electrical systems to fail. On the other hand, the battery acts as a storage unit for electricity, providing the initial power needed to start the engine and ensuring that the vehicle has a constant supply of electricity when the engine is not running. The battery also helps stabilize voltage fluctuations in the electrical system and provides power to accessories when the alternator cannot keep up with the demand. While both the alternator and battery play integral roles in your car's electrical system, it's important to note that the battery has a limited lifespan and typically needs to be replaced every four years, even if it appears to be functioning properly. Over time, the battery's ability to hold a charge diminishes, leading to decreased performance and potential issues with starting the vehicle. Even if a battery tests "good" during a diagnostic check, it may still be nearing the end of its lifespan and could fail unexpectedly. Replacing your car's battery every four years is a proactive measure to prevent breakdowns and ensure reliable performance. By staying ahead of battery deterioration, you can avoid being stranded with a dead battery and potentially damaging the alternator due to excessive strain. Regular maintenance and timely battery replacements can help keep your car running smoothly and avoid costly repairs in the long run.

Do Tires Expire?

Image
  Do tires expire is a question that our customers often ask. For years many motorists have relied only on tread depth to know when it is time to replace them. Unfortunately, the age of your tires is also a factor. Over time, tires can dry out and crack. Excessive heat and sunlight contribute to this and can cause tire to unexpectedly fail, even when there is plenty of tread remaining on the tire . Tire manufacturers offer different opinions regarding how long tires will last, but the National Highway Transportation Safety Administration (NTHSA) recommends that you replace tires after six years . How do you know how old your tires are ? The best way to know the age of your tires is to check the Department of Transportation (DOT) code. The manufacturer stamped it in the sidewall of your tire. DOT numbers identify the manufacturer and the make of tires, but they also tell you when the tires were made . The last four digits of your tires’ DOT code tell the month and year of manufa...

What is a Belt Tune Up?

Image
A Serpentine Belt is the rubber Drive Belt that causes the pullies on your car's Alternator, Air Conditioning Compressor, Water Pump, and Power Steering Pump to rotate and to create electrical and mechanical power. Rotation of the alternator creates your car's electrical power. Gas powered vehicles have one or more Drive Belts, at least one Belt Tensioner, and they may have one or more Idler Pulleys. Belt Tensioners insure that the Alternator, A/C Compressor, Water Pump, and Power Steering Pump continue to spin with the rotation of the engine. Idler Pulleys are simply pulleys that do not drive other components. Idler Pulleys are used to route the Serpentine Belt.  With use, a Serpentine Belt will stretch and wear.  Belt Tensioners and Idler Pulleys also wear, and this will cause additional belt wear. When a Serpentine Belt breaks, the components that it drives will not longer function. Because of this, Sant Automotive recommends that you replace your Serpentine Belt(s), Idler ...

What Do Spark Plugs Do?

Image
  Spark Plugs are the small electrical parts that provide the power to ignite the fuel in gasoline powered devices. As electricity passes between the Spark Plug's electrodes, gasoline ignites causing an explosion that powers your vehicle. Spark Plugs fire once every two engine rotations. This means that if your engine is running at 800 RPMs, your Spark Plugs will fire 400 times per minute. The heat produced by these explosions causes the Electrodes to wear which increases the gap between the Electrodes. The increased gap causes your vehicle to use more fuel to produce the same amount of power.  Worn Spark Plugs reduce Gas Mileage, and unburnt fuel will damage your car's Oxygen Sensors and its Catalytic Converter. Also, the longer that plugs stay in a vehicle, the more likely they are to become stuck in the engine's cylinder head. If a spark plug breaks, it can be very expensive and time consuming to extract it. For these reasons, Sant Automotive recommends that you change y...
