Car Diagnostic: The Details

If your car is acting up, you could take it into a repair shop for a total vehicle inspection, but there is an easier way to troubleshoot. The “check engine” light and other misfires can indicate a wide range of issues that can be difficult to determine. An auto diagnostics test will investigate the computer system in your car, and reveal any problems going on quickly and accurately. To learn more about the specifics of an auto diagnostic test, keep reading this blog post.

The Process

Once you take your vehicle in to the dealership or repair shop, a certified mechanic will link a car diagnostic computer to your vehicle’s computer processor, sensors, and microchips. This process takes just a few minutes, rather than the hours needed to perform a total car inspection. The convenience of the auto diagnostic makes it a necessity when your car is off-kilter.

The History

Back in the year 1996, the Environmental Protection Agency established that all cars sold in the United States must use the same diagnostic systems so repair shops can diagnose all vehicles regardless of the make and model. The diagnostic test that was created does a total-vehicle checkup, responding to a set of codes that signal what the mechanic must focus on.

What Does it Detect?

A simple auto diagnostic will tell you a number of things about your car. For example, it will indicate whether it has ignition timing issues, buildup in the engine, engine RPM inconsistencies, and coolant levels. The mechanic can also look for manufacturer notes and other vehicle history information during the scan, which will allow them to tailor repairs to your car’s needs. During the diagnostic exam, the computer will reveal a report with codes that indicate areas that need repair. Since the test will notify you of minor issues, you will be able to avoid future costly repairs.

How Often?

Professionals recommend that people perform annual checkups on their vehicles to ensure their proper function. Once it’s been a year, you should head on in to the auto shop to be safe. Even if you don’t notice any present issues with your vehicle, there could be minor problems with the exhaust system, transmission, brakes, or more that could lead to major future damage. Get ahead of the problem with annual checks.


There is nothing easier than taking your car in for a diagnostics check, which takes only an hour or two. To keep your car in great shape for longer, make sure you get it done every year. If you’re in Del City, OK come on in to H.W. Automotive Inc the next time you’re ready for auto repairs.

Check Your Engine!

Saying that your car’s engine is an important component of your vehicle is an understatement. Without your engine, you wouldn’t be able to go anywhere, it would just be a stationary pile of metal parts. A vehicle without an engine is like having a bike with no pedals – it is pretty useless. Unless you’re going downhill the entire time, you are going to need an engine to make it go forward.

What Does It Do?

You are probably thinking to yourself, what does a car engine actually do? To put it very simply, the engine converts all that gas you fill up on at the gas station into energy, which in turns makes your car move. Gas and air are sucked into the engine which produces tiny explosions, or combustions.

Hence the name “internal combustion engine”. The tiny explosions move the pistons, turning the axle which then proceeds to move your car. This, in layman’s terms, is how your car engine works, and why it is extremely important to keep it in proper working order.

Signs That You Need Engine Repairs

If your check engine light begins to shine, it is best not to ignore it. The check engine light is a sensor that is part of your vehicle’s onboard system. There are a number of issues that could set off the light, but this is the most obvious sign that your engine is in trouble and is going to be in need of maintenance. But that handy check engine light isn’t always going to turn on, so you must be vigilant in paying attention to what your car’s engine is telling you.

If you are at a stop, parked, or in neutral and feel your car sputter and jerk, then your engine could be in bad shape. Loud thumping or banging coming from your engine is also a telltale sign of some direly needed repairs. Make sure you keep a lookout for oil leaks because your engine needs to stay lubricated in order to function properly.

So if you didn’t know before, then hopefully this shows you the importance of keeping the engine of your vehicle well maintained. If the check engine light is on or is showing any one of the symptoms previously stated, make sure you take it to an auto shop as soon as you are able to. The longer you let the problem linger, you risk the issue becoming much worse. A minor fix could become a major one, and a major repair is much more expensive. So keep that engine in shape, and keep driving friends.

The Most Common Transmission Problems

A transmission is one of the most important parts of a vehicle. This complex mechanical system is designed to direct any power from your engine into the driveshaft which helps turn the wheels. As a result, any problems that are inflicting its performance, including excessive wear and tear, can cause some serious drivability issues up to the point of making it inoperable.

By following proper preventative maintenance protocols, you can ensure the longevity of your transmission while avoiding any costly repairs. However, whenever you transmission does have any problems, it’s a good idea to be able to recognize what you could be dealing with. In this article, we’ll run down two of the most common transmission problems that can happen if it isn’t well-maintained.

Low Transmission Fluid or Leaks

Low transmission fluid levels or leaks are easily the most common type of problems this component can experience. Automotive Transmission Fluid, or ATF, helps lubricate, clean, and conditions the hydraulics. If it gets too low or is completely empty, your engine will start to seize up and stop working in its entirety.

Leaks also happen to be one of the most recognizable symptoms. The fluid itself normally has a bright red color, so if you discover this liquid deposited in your driveway, you just need someone to patch up the holes. If it has a dark red color or has a burnt smell (usually through overheating fluid), you will need to have your transmission fluid changed or flushed with the strong possibility of further repairs.

The way to check your transmission fluid level is the same as oil. Take your car for a drive for a few minutes in order to warm it up and then take a look under the hood to read the dipstick (with the vehicle on even ground). For those with a manual transmission, there should be a transmission case through the fill plug.

Unlike oil, transmission fluid is not consumed by your car, so you should be able to tell quite clearly if there is a leak somewhere. If it will be a while before you can get it fixed, top off the fluid until you have your vehicle serviced so your engine can still do its job. Also, make sure you follow your owner’s manual so you don’t overfill, which can create even bigger issues.

Check Engine Light

This is clearly the best indicator that something is about to go wrong with your transmission or it has already happened. While this light could illustrate another problem, you should always take this light seriously. Your vehicle has a number of sensors located throughout the engine to alert the system if it starts to recognize any causes for concern. It can even pick up any jerkiness or vibrations you may not have felt yourself.

When that check engine light appears, take your vehicle in for an inspection as soon as possible. Through the shop’s diagnostic tools, they can find out what is going on to fix the problem immediately. Don’t delay as it could be warning you of a more serious problem.

Bottom line, if you start to hear a whining or grinding noise coming from your transmission, this could be the result of a mechanical issue. This is why it’s so important to have your transmission go through regularly-scheduled maintenance to ensure its operation while avoiding expensive repairs. That goes double if you start to hear any unusual noises or a slipping or dragging clutch.

You will be able to save money in the long run by bringing your vehicle in for repairs. In the meantime, by keeping yourself informed about the common transmission problems, you can also avoid being overcharged for a simple service.
