Using Good Quality Parts.

When something goes wrong with your vehicle, it can be tempting to take the cheapest route. With eBay, Amazon, and the countless other sources for car and truck parts on the market today, many people decide to go that route to save some money. Here we choose only quality automotive parts for our Northern Virginia drivers at Great Falls Auto Service because we want to ensure their parts match our commitment to providing them high quality repairs.

Using quality parts ensures Reliability. Reliability is a big concern when it comes to parts. Two parts that look the same with different prices are often very different. Manufacturing tolerances, procedures, and materials used make all the difference in how reliable a part will be. When it comes to machinery, one-thousandths of an inch can make all the difference.

Cost. Saving some money on a cheaper component may save you a few bucks initially, but it can quickly get expensive. If the part fails, in the best case scenario you’ll be spending the money again on a replacement. More than likely, you’ll be replacing that part, plus whatever that part damages when it fails - a cheap wheel bearing can ruin your tires, your brakes, and your suspension along with the bearing itself. Plus, a lot of the cost from vehicle repair comes from the actual job itself. A component that costs ten dollars but takes 12 hours to replace isn’t a job you want to pay for twice. It’s always better to do it right the first time.

Warranties. Warranties are important - a good one not only protects the part, but the labor and other damage associated with it if it fails. We want to ensure you get quality repairs backed by parts from suppliers that offer the best products available for your vehicle repair. If possible, we want to ensure you have a warranty on those products and one that will be honored.

Our technicians only use quality parts and only perform quality work because we want our customers to have their vehicles running like new! For the best repair and service shop in Northern Virginia, call or stop by Great Falls Auto Service today.

How to maintain your battery properly!

Your car’s radio and headlights, plus a slew of other important functions, are powered by an electrical current generated by your vehicle’s engine. A vital part of generating electricity is having a place to store it while it’s not being used. This is where your car battery comes into play. The battery of your vehicle holds electrical energy while the car is off in order to help the engine turn over and create a spark to start internal combustion. Without a working battery, your car will not be able to start. If you allow our team here at Great Falls Auto Service to perform proper maintenance, an average car battery can start your car reliably for roughly four years.

The typical car battery found in most modern cars is of a lead-acid storage design. While we don’t suggest it, if you were to look beneath the surrounding casing of a standard 12-volt car battery, you’d find six connected cells. In these cells is a toxic concoction of hydrogen-oxygen gasses and sulfuric acid, which can burn your skin on contact. The American National Standards Institute advises wearing gloves and eye protection when handling your car battery. We’d also recommend you not smoke around your car battery.

A car’s battery is connected by two metal terminals – one positive (+) and one negative (-) – located at the top of the battery’s casing. These terminals can develop buildup over time, which can inhibit electrical flow. If there are encrusted deposits on the battery, bring them in and let our team here at Great Falls Auto Service clean them for you! This will ensure that current flows more freely through the terminals and then to the necessary components.

We will also check that the cable ends are securely attached to the terminals. A loose cable end can cause a car not to start and mimics the symptoms of a dead battery. It's important to let a technician check the cables on your battery. Removing the positive terminal before the negative can result in a spark, which could ignite anything flammable in the engine compartment and cause an explosion.

If you are facing issues with your battery or want to get it checked to be sure it is properly maintained, bring it to our team today. Here at Great Falls Auto Service, your safety is our top priority, and we want to keep you on the road for years to come!

Do you want to get more miles per gallon?

At Great Falls Auto Service, efficiency is a concept that interests us. While your fuel economy is largely dependent on what kind of car, truck, or SUV you drive, there are a variety of tips and tricks to get the most bang for your buck. We’ve provided a few of our favorites here.

Check your tire pressure, regularly. Low pressure isn’t always caused by leakage; your tire pressure will drop with changing weather and over time. By keeping your tires inflated to the correct pressure, you significantly reduce the friction your engine is constantly fighting. Not only does this save your tires, but you’ll also notice better gas mileage as well.

Accelerate smoothly. Hard acceleration wastes more gas than anything else...you use a lot more fuel getting your car up to speed than you do maintaining that speed as you drive down the road. Avoid accelerating as much as possible, and practice keeping steady momentum to reduce fuel consumption.

Don’t speed. The faster you drive; air resistance increases exponentially. Air resistance is actually the greatest force affecting your vehicle as you drive and fighting as little of it as possible will greatly increase your gas mileage. Plus, the faster you go, the higher your engine has to rev, which burns more fuel as well.

Keep your car maintained. Faulty sensors, neglected tune-ups, vacuum leaks, expired spark plugs, and a myriad of other potential issues will negatively affect your gas mileage. A vehicle with faulty oxygen sensors, for example, can lose ten miles per gallon. Make sure your car, truck, or SUV is running well...it not only keeps your car on the road longer, but it also saves you money in the process.

For all your maintenance and repair needs, trust the experts at Great Falls Auto Service. Our mechanics have the professional knowledge and ability to service your vehicle, no matter what you drive, and keep it reliably on the road for years to come. Call or drop-in today!

What makes up an Air Bag?

At Great Falls Auto Service, we believe it’s important for you to know how different systems in your car, truck, or SUV operate. Whether you want to know what to watch out for, or you’re just curious about how things work, we’re here to supply the answers.
Airbags are an element of your vehicle that you probably don’t think about too much since you don’t use them that often. However, they are a revolutionary and interesting component in all modern automobiles. They are simultaneously a testament to modern engineering, and actually quite simple.
There are only a few main components to an airbag. A sensor, an ignitor, a chemical compound, and the airbag itself. When the sensor is activated in a collision, it sends an electrical pulse to the ignitor, a heating element that ignites a compound, causing a rapid expansion of harmless gases inside the airbag, filling it almost instantly. That’s right, an airbag is really nothing more than a controlled explosion, detonated by an electronic signal. All of this happens within a fraction of a second, providing passengers in the car a strong cushion between them and less forgiving parts of the car.
Airbags rarely fail. However, if there’s an airbag warning light illuminated on your dashboard, it’s important to figure out why as soon as possible. The light indicates that something in the system has malfunctioned, and it’s possible your airbags won’t be there for you if you need them.
If you’re having complications with your airbags, and for all your other repair or maintenance needs, our team of expert mechanics has you covered. For the best auto service shop in Sterling, call or stop by Great Falls Auto Service today.

Is It Time To Replace Your Ball Joints?
separated ball joint that needs to be replaced
We know you’re busy. At Great Falls Auto Service, we also know that while there are certain issues with your car, truck, or SUV you can ignore for a while, some of them shouldn’t wait. While serious issues are often obvious, sometimes they aren’t - ball joints are one such case.

The ball joint is a component of your suspension. A ball joint is a big, round bearing pressed into a cup, essentially, which connects your control arm to the steering knuckle. The ball joint is able to compensate for movement in the suspension, connecting your car to the suspension system underneath. Really, the only important takeaway here is that the ball joint is responsible for bearing the weight of your car; when one fails completely, the body of the car will fall, likely all the way to the ground. The wheel is engulfed by the wheel well, and the car is rendered inoperable. As you can probably guess, this is a huge problem on the road...not only do you lose the support of your vehicle, but steering goes with it, and the vehicle will pretty much be stuck wherever it breaks. If it fails while the vehicle is in motion, you can imagine the sort of trouble this situation might cause you.

So how do you know if one of your ball joints is failing? While there aren’t immediate signs that make you think “I don’t know what that sound is, but it definitely isn’t good,” there are telltale symptoms of imminent ball joint failure.

The most common is an arrhythmic knocking or clunking sound, particularly over bumps or rough pavement. It sounds sort of similar to two bowling balls being knocked together. Another sign is loud squeaking when the suspension bounces over bumps or turns - it’ll sort of sound like an old noisy bed. While loud squeaking could also be due to a variety of bad rubber bushings, it’s best to play it safe. It’s also a good idea to have ball joints lubricated at regular intervals, to make sure they last.

Replacing a ball joint isn’t a big deal and is certainly less hazardous than waiting until one fails completely. If you suspect your car is in need of new ball joints, have one of our technicians take a look. Our team of expert mechanics has the knowledge, equipment, and ability necessary to service any type of vehicle, whether the job is big or small.

Air Filtration & Why It Is Important

dirty air filter vs clean filter

Your vehicle's engine needs clean air to burn the fuel – and it needs a lot of clean air. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Great Falls Automotive, we ensure you get the best air quality in your vehicle and explain the process of where this dirty air is going to our area drivers.

Dirty air passes through the mass airflow sensor and starts to accumulate on the delicate sensor element. The mass airflow sensor measures how much air is getting into your engine. When the airflow reading is incorrect, your family car engine doesn’t get the proper amount of fuel. It runs rough and doesn’t perform as well as it should.

Eventually, the sensor is so damaged it needs to be replaced – which is pricey. In fact, you could buy a case or two of air filters for the cost of a sensor replacement. Of course, that dirty air keeps on going through to your family car engine where it’s burned along with the fuel, which dirties up your combustion chamber and increases harmful exhaust emissions – not a good thing for community air quality, not to mention our lungs.

When one of our technicians brings out your dirty air filter and recommends a replacement, remember the cost and poor performance that can be waiting for you down the road if you neglect this simple automotive service. Talk to us at Great Falls Auto Service about general automotive care and maintenance, your safety is important to us and we have been providing quality auto repair services for cars, trucks, vans, and SUV for many years.

“Spark plug” is a word you are likely familiar with; it’s one of those car terms that you’ve heard your whole life. You know they’re important, you know sometimes they need to be changed. But how do you know when it’s time to replace them? What do they do, and where do they go wrong? Great Falls Auto Service in Sterling Va. has the answers.
Your spark plugs are an essential part of your engine. While much of car technology has improved, and old technology has been replaced, spark plugs have remained integral and virtually unchanged since the beginning.
The spark plug is a simple mechanism with a simple job - two points, with a gap in between them, because an electrical charge to jump across the gap, igniting the fuel in your cylinder at just the right moment, creating the combustion in your engine which powers your car. Essentially, the spark plug creates a spark that ignites the gasoline. Changing spark plugs used to be an easy maintenance item that anyone could do at home. However, with the advent of v-shaped engines, front-wheel-drive cars, aluminum heads, and engine positions that aren’t exactly conducive to easy maintenance, the job has become a bit more technical on many modern vehicles.
A simple job that took your grandpa 20 minutes in the 1950s, has transformed into one which may require the removal of a wheel, special tools, certain techniques, and runs the risk of stripping out the spark plug hole or damage to other components. What this also means is spark plugs have become a maintenance item people often neglect, running the same spark plugs well after their time has expired. Another common issue is as follows: a home mechanic begins replacing spark plugs, eventually runs into one that is too difficult to remove, and opts to just change all the easy ones. When someone checks the plugs to see if they have been replaced, they too check the easy ones, see that they are new, and assume all of them have been replaced. Now the vehicle has mostly new plugs, and one hidden plug in a dark recess of the engine compartment that desperately needs replacing. Since the other plugs are new, the engine will probably keep running, but will exhibit signs of a problem.
So how do you know if your plugs need to be changed? Low power, engine vibration, or a check engine light are all signs that one or more spark plug needs to be replaced. Even if your car runs well, it may be time for a replacement - once the plugs wear down or corrode, the spark weakens, and your engine suffers a slow decrease in performance that you may not notice over time. Plugs can also crack or break internally, rendering them useless. If your car is running poorly, your spark plugs may be the culprit. If your car is overdue for a factory recommended spark plug change, or you aren’t sure when they were changed last, it’s time to at least have them inspected.
The bottom line is that spark plug maintenance is essential. They are cheap, and to a professional with the right equipment, they are also easy to change. If your car isn’t performing like you think it could, or you are overdue for new plugs, let one of our expert technicians at Great Falls Auto Service take a look. We can tell you if they need to be replaced, and to the trained eye, a spark plug is also an indicator of how well your engine is performing. If it is time to replace them, we’ll handle that too. Trust Great Falls Auto Service to keep your engine running smoothly and your mind at ease.

Is your A/C SYSTEM ready for summer?

Heating & Air Conditioning Facts & Information

Your vehicle’s HVAC system is important not only for comfort, but for defrosting and defogging windows, uninterrupted flow of engine coolant, and proper operation of belts which drive your alternator, power steering, and water pump. Heating and cooling issues come in a variety of shapes and sizes depending on the type of car or truck you drive and the make or model of that vehicle, but Great Falls Auto Service can handle them all.

Your heat and A/C system are complicated, to say the least, requiring the right tools, and constant training to keep up-to-date on the new information and diagnostic tools required to take care of your specific system. Our technicians at Great Falls Auto have experience on all makes and models and can quickly find and solve any issue you might have with your heat and A/C system should it be due to an issue with your compressors, high-pressure lines, special gasses, condensers, actuators, electronic and vacuum signals, or multiple other aspects of your car or truck. Your air conditioning system has to work in harmony to effectively cool your vehicle infrastructure and when needed heat the inside of your vehicle for your comfort. The longer an A/C system remains broken the more problems it will develop, so it’s a good idea to have it serviced regularly.

We have found that the heating systems are generally far more reliable than A/C since they primarily operate on circulating engine coolant. However, if you’re having heating issues, the consequences are usually far greater if neglected. Lack of defrosting and defogging ability is not just inconvenient but also extremely unsafe. A clogged heater core can cause engine overheating, and a failed heater core will leak coolant into your vehicle, damaging other components. If your heater is misbehaving, have it inspected immediately. Often a simple coolant flush will correct the issue if we can catch it quickly.

When you bring your vehicle to the ASE certified automotive specialists of Great Falls Auto Service for an HVAC check or a repair of your air conditioning, heating, and ventilation system, our highly trained technicians may perform any of the following services:

Air conditioning performance test
Radiator cooling fan and condenser check
Thorough inspection and repair and replacement of HVAC components due to leaks degraded seals and malfunctions including hoses, gaskets, and belts
System pressure checks, such as with hi and low-pressure hoses
Air conditioning recharge
Refrigerant refill
Replacement or cleaning of the cabin air filter
Condenser repair and replacement
Compressor repair and replacement
Evaporator repair and replacement
Accumulator/receiver-drier repair and replacement
Radiator repair and replacement
Thermostat repair and replacement
Water pump repair and replacement
Regular and preventative maintenance of your HVAC system will ensure you avoid many of the preventable extensive repairs that arise from failure to properly service and maintain your vehicle’s air conditioning, heating, and ventilation system. If you have noticed exterior or interior leaks, odd smells or a failure to maintain cabin temperature, our technicians are qualified and prepared to quickly diagnose any HVAC issues in your vehicle and efficiently complete any necessary maintenance or repair services to have you back on the road as soon as possible. Sometimes just rolling down the windows and living with the problem isn't the "simple solution" you think it is but the start of really causing major damage to your vehicle.

Our shop is here to save you money and keep you on the road going where you want - when you want, so if you have questions or issues with getting your service work done simply give us a call here at Great Falls Auto where we have you covered. Whether your car, truck, or SUV needs a coolant flush, an A/C system flush or charge, actuator replacement, or any other sort of repair or maintenance we will ensure you drive in comfort again.

Fuel Saving Tips

Keep your tires inflated at their proper levels. Under-inflated tires create rolling resistance which means your engine uses more fuel to maintain speed.
Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.
Use the air conditioner sparingly. The air conditioner puts an extra load on the engine forcing the vehicles to use more fuel.
Keep your windows closed as much as possible. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.
Avoid idling for long periods of time. If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel than letting it idle.
Stay within posted speed limits. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph increases fuel consumption by as much as 20 percent.
Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduces your fuel consumption.
Keep your engine well-tuned. A fouled spark plug, or a plugged/restricted fuel injector can reduce fuel efficiency by as much as 20 percent.
Check your owner's manual to find out what fuel octane rating your car's engine needs.
Have the fuel filter changed every 30,000 miles (or per manufacturer specifications) to prevent rust, dirt, and other impurities from entering the fuel system.
Replace your air filter and PCV valve more often than recommended if you drive in dusty conditions. If you are experiencing engine problems such as hard stops, rough idling, stalling, diminished power, etc., make sure to get them corrected at a quality automotive shop.

Do you have an ALIGNMENT issue?

When your car, truck or SUV begins to shake, vibrate, or pull to either side while driving it typically means it's time to bring it into our shop here at Great Falls Auto Service, for an alignment! Doing so will save you serious wear and tear on tires and it is an easy fix if caught early. But what exactly is a tire alignment and why is it important?
Wheel alignment is important for many reasons. First off, a properly aligned car drives better and handles the road with more agility. Then there is the cost factor. An out of align car will wear tires out in as little as a few thousand miles. With the high cost of tires today it really pays to keep your car in proper alignment. We look at our customer's vehicles each time they come in and set up a vehicle maintenance plan for them, alignments are part of your vehicle maintenance and checked typically every 6,000 miles on average. Wheel alignments ensure optimal vehicle driving and help your tires last longer, your vehicle will drive better.
Alignments can also be necessary after a shock to your front wheels like running through a pothole, hitting a curb, driving on back roads, and bumping on solid objects with your tires here on our local streets in Northern Virginia. The suspension and front-end assembly of your vehicle you drive are comprised of many different components, which keep your tires centered and resting flat on the pavement. When things wear out or move over a fairly long period of time, it’s necessary to reset your front-end components to get your car, truck, or SUV driving straight again. Avoid driving too much if you believe your tires need an alignment; investing in a repair at Great Falls Auto service as soon as you notice any of the symptoms listed as the more you drive, the worse the damage is.
Important Tips: To save you hundreds on repairs with new tires, suspensions & steering parts, make sure to look at your tires for uneven tread wear.

Signs of Off Alignment Checklist:
- Your car or truck pulling to one side, or the other is a great sign that you need an alignment. Simply get on a straight road like an interstate and release the wheel for a few seconds and see if it pulls. When you come into the shop let us know which side it pulls towards.
- If the steering wheel is crooked! Your alignment is off! Sounds odd but it is true, looking at your steering wheel when you are going straight if it isn't properly lined up you DO have a problem.
- When you are driving on a smooth road and your steering wheel is vibrating or shaking, we have a problem which could be an alignment, or it could be a tire balance problem.
- Your tires are starting to wear unevenly or rapidly is a sign of needing an alignment.
