Smooth Operator (Shocks and Struts)

Few of us ever drive somewhere without encountering some pretty rough roads, and it's amazing how well our vehicles are able to smooth out the ride. Thank your shocks and struts.

The two parts are similar.  Some cars have shocks in the rear, and struts in the front.  Others have struts all around.  A shock absorber uses a cylinder filled with gas or liquid that's connected to your vehicle's frame and axle.  When your vehicle encounters an imperfection in the road, the shock dampens the motion. 

A strut is essentially a shock absorber mounted inside a spring and can support more weight than a shock by itself.

Shocks and struts take a lot of punishment and wear out.  When they do, your tires are not contacting the road as much as they should, and that can result in a bumpy, unstable ride. Worn-out shocks and struts also transfer the impacts of road imperfections directly to your vehicle's body which can cause further damage to other parts.

You can tell when your shocks and struts are wearing out when your vehicle's ride is bouncy, you feel the bumps and body motion a lot more than you used to, or you may see fluid leaking from the areas near the wheels.

How often your shocks and struts need replacing depends on what surfaces you drive on, how far they've traveled, and how long they've been on the vehicle.  Our technicians can check the condition of your shocks and struts and advise you when they need to be changed.  Shocks and struts should always be changed in pairs.  

Because shocks and struts wear out gradually over a long time and distance, experts recommend you have them checked at least once a year.  Plus, if you know you've recently hit something especially hard in the road, you should have your suspension checked just to make sure it's ok.

A Bumpy Ride (Strut Assembly Replacement)

If you’ve noticed your vehicle’s ride has lately been bumpy or you’re hearing strange noises when you drive over bumps, you may need new struts.   The strut assembly is part of your vehicle’s suspension system that’s used to absorb the irregularities on the surfaces you drive on.

You have probably heard of shocks or shock absorbers.  A shock is a piston with gas or liquid inside.  When you hit a bump, that shock absorbs the blow. Struts are similar to shocks but they also have a coil spring for extra strength.  They’re often used in the front of the vehicle because of the engine’s extra weight. 

As you might imagine, your struts take a beating every day.  Eventually, they will wear out, and your wheels and tires won’t stay connected to the road as well as they used to. In addition to a bumpier ride, you may notice your tires starting to wear with failing struts because those tires aren’t in contact with the road surface as evenly as they used to be. 

When you bring your vehicle in to us, we’ll run some tests to determine what’s going on and what condition your suspension components are in.  Your vehicle’s manufacturer recommends struts to be replaced at certain intervals, and it’s important to change them out with the same type of equipment.  They should always be replaced in pairs on the same axle. 

After your struts are replaced, your suspension should be aligned so everything is headed down the road in the right direction. After that, driving should be smooth sailing.

What's in a Number? (What Tire Numbers Mean)

You've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information.  There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on.  Let's check out this example found on an SUV: P245/70R17 108T.

The first letter, P, means it's intended for passenger vehicles.  If there's no letter, it means it's a metric tire.  If there's an LT at the beginning or end that means a tire designed for light trucks.

Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall.  The number that follows in our example, 70, means the height of the tire is 70% of its width.  The letter after that in our example, R, describes the type of tire (on this vehicle, radial).  Following that is the diameter in inches, in our SUV example, 17 inches. 

How much load the tires' sidewalls are designed to take is what that next number is all about (108 in our example).  The higher the load index, the more weight the sidewalls can take.  And the last letter is the speed rating of the tire, in our example, T.  The further along in the alphabet that letter is, the higher its speed rating.  So now you know what those letters and numbers mean.  But why are they important?

When you are getting ready to replace those tires, those numbers are telling you what the original equipment was when your vehicle was new.  Sticking with the same rated tires is always a good idea.  If you don't know what you're doing, trying different sized tires and wheels can cause real issues when it comes to performance and safety, considering all the computerized systems now found on vehicles.  When in doubt, consult your service advisor when it comes to buying new tires.  He or she knows what those tire numbers and letters mean… and a whole lot more.

On Board Diagnostics for Your Engine

Starting in 1996, East Coast Automotive Services service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at East Coast Automotive Services. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. Jupiter drivers need to understand that doing so can cause major damage.

When a vehicle is brought to East Coast Automotive Services in Jupiter because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your East Coast Automotive Services technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at East Coast Automotive Services exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at East Coast Automotive Services. But the ensuing process of actually diagnosing a vehicle's trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for Jupiter vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn't indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don't have the ability to read the history stored in an engine's computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. East Coast Automotive Services invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it's good auto advice to use East Coast Automotive Services for your car care. In the long run, it can save you time, unnecessary expense and frustration. East Coast Automotive Services can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.
