Today we would like to highlight the often-overlooked synergy between the alternator and battery. Together, they form a crucial partnership that drives the seamless operation of your vehicle's electrical system.  What Does The Battery Do? The battery serves as the initial power source, supplying electricity to start the engine and power the vehicle's electrical components when the engine is not running. It stores chemical energy in the form of lead plates and sulfuric acid, converting it into electrical energy to power the starter motor during ignition and supporting the electrical system when the engine is not operational. The battery acts as a reservoir of electrical energy, providing the necessary power for various vehicle functions, including lights, audio systems, and other electronic accessories. What Does The Alternator Do? Complementing the role of the battery, the alternator serves as a generator, converting mechanical energy ... read more

If you have ever heard of a Hemi engine, you probably only know that it's put in the fast muscle and race cars or something along the lines. Well, partially true it's also used in a lot of other vehicles. That's because it pushes a lot of horsepower while being just like a normal engine - with a slight change hinted at in its name. Read along to find out what Hemi stands for and its pros and cons. Hemi Engines Explained The Hemi or Hemispherical V8 engine differs from all other engines with its cylinders' shapes. The top of the cylinders is a flattened hemisphere at the center, which is a spark plug, fuel/ air injectors, and an exhaust valve. This particular shape provides a much lower loss of heat, therefore, more power.  The first Hemi engines were equipped with hemispherical cylinders, which were not that good. That's why today's Hemis have a flatter cylinder design than their predecessors. The first one was introduced in 1953 on the Dodge Red Ram, fo ... read more

A vehicle's  check engine light (or "service engine soon" light) usually indicates a problem with the ignition, fuel, transmission, or exhaust system. Often, it comes on for one of the following problems below: Gas Cap  This is the easiest and quickest fix, which is why most people hope that is why their engine light came on. When you forget to screw your gas cap all the way, or it is damaged, your car will detect a “leak”. The cap is supposed to keep the fuel vacuum sealed.  Spark Plugs Worn spark plugs or plug wires can initiate the check engine light. These are necessary to ignite the engine. If they’re over 100K miles, your car is most likely due for new ones. And you may experience misfires until you replace them. Mass Airflow Sensor  This component measures the amount of air entering the engine to ensure the right fuel-to-air ratio gets burned. If this sensor is on its las ... read more

When it comes to auto maintenance, most drivers tend to forget or not bother with replacing their filters, specifically the cabin air filter. Even though this filter doesn’t directly affect your vehicle’s functionality, it can cause an unfavorable atmosphere inside your car. Here are several reasons why you should change your cabin air filter on time: Bad Odors - Since the cabin filter is responsible for keeping out dirt, dust, and other pollutants, leaving it to build up can cause a stench. It might smell musty and overall unpleasant whenever you turn on the A/C or heat. Therefore, changing your cabin air filter can help deliver odorless, clean air to the passenger cabin. Increase Allergies - Air filters trap pollen and dust, which can be harmful to you. If you or your family members have sensitivities to these air pollutants, it can be very uncomfortable for you or them to be inside the car. Foggy Windows - A dirty cabin filter will clog up the HVAC system. Therefore ... read more

Worn tires are not only an inconvenience but can cause accidents if left unchecked. But don't worry, we will share with you the top 5 signs that your vehicle needs new tires, and what you can do about it! 1. Tread Wear One of the most common indicators that you need to retire your tires is tread wear. Worn tire treads can pose serious problems, especially in severe weather conditions such as rain and snow. The tread of the tire allows water and slush to escape and allow the rubber to meet the road. Worn tires have shallow tread or no tread at all and are less effective at evacuating water from the contact patch. This leads to hydroplaning, where the tire floats on top of the water, and loss of control. The tread wear can be checked by locating the tread wear indicators, small bars inside the tread. When the surface of the tire is even with these bars, it is time to replace the tires. Tread depth inspection is a crucial part of road safety. 2. Tire P ... read more

Pothole damage is a common road hazard that can cause damage to your vehicle. However, the damage may not be obvious. Say you nicked a porthole, just barely, or hit one straight on. Regardless, your vehicle could sustain some damage. But the intensity will depend on your speed during impact and the pothole's depth. Either way, these damages, whether obvious or hidden, can have long-term effects. Potential Potholes Damages 1. Wheel Bearing Damage Wheel bearings can fail following hitting a pothole. When your vehicle's tire goes into a pothole, the wheel bearing jolts, causing a minor indention to the bearing races. If unnoticed, the bearing grease will have turbulence over the area, causing less lubrication. Ultimately, the lack of lubrication will lead to wheel bearing failure. 2. Suspension Damage A severe pothole can damage the components of your car's suspension system. A pothole can impact components including ball joints, sway bar links, control arm bus ... read more

To drive smoothly and seamlessly, your car’s engine needs to stay at a stable temperature range. To make that happen, a fluid called coolant/antifreeze gets pushed throughout the engine to regulate the temperature. Unfortunately, the coolant doesn't stay effective forever. Over time, contaminants and grime can build up in the cooling system. A coolant flush can solve this problem and protects the engine from corrosion, keeping it in the best shape possible. Besides a simple inspection, how can you tell when you need a coolant flush? Low Coolant   You can pop open the hood and visually check your coolant levels. If the fluid looks too low, you may have a leak. Be sure to check if any bright-colored fluid is around or under your vehicle. We can also check for you when bringing your vehicle into Airpark Auto Pros. Bad Coolant Quality  Another sign that may trigger a need for a fluid flush is if you find the coolant to be contaminated or discolored.  Eng ... read more

The cooling system is a vital system in our automobiles – it keeps the engine safe and operable by stabilizing its temperature. A key part of the system is coolant/antifreeze. Over time, the solution will break down and become less effective at cooling.  Can Coolant Expire in the Bottle? When you buy coolant at an auto supply shop, it typically has a shelf life of 1-5 years, depending on the product. The manufacturer is required to put an expiration date on the bottle, so don’t worry if you forget. Always look at the expiration date before adding the solution to your car. Can Coolant Expire in a Car? Coolant degrades over time in your engine. As it flows in and out of the engine, it can pick up metals, dirt, and debris. Most automakers recommend flushing your coolant every 30,000 miles. Dirty coolant can corrode cooling system components and cause leaks. Old and ineffective coolant can also have a reduced boiling point, which can lead to engine overheating. Signs ... read more
