Automotive Tips from McLearen Shell: Serpentine Belt Overview

The technicians at McLearen Shell know your serpentine belt drives important engine accessories like your alternator, air conditioning compressor, and power steering. In some cars it may also power the power brakes or water pump. The serpentine belt is powered by the engine and winds around pulleys and the accessories. Some cars in Herndon have two serpentine belts.

The serpentine belt, the belt tensioner (which maintains the appropriate tension on the belt) and the idler pulleys are together known as the accessory drive system.

Now your serpentine belt and the belt tensioner will just wear out over time – that’s why your vehicle manufacturer has a scheduled belt replacement interval. The team at McLearen Shell in Herndon can inspect your serpentine belt for wear and get it replaced if it’s time.

10 Services Herndon Drivers Often Overlook

We live such busy lives nowadays: work, social events, running the kids all over Herndon. Some days it's all we can do to keep track of everywhere we need to be. That's why you've gotta be organized. Smartphones, calendar apps - we have to keep track of it all.

So let's talk about schedules. Specifically, automotive service schedules. And particularly, the scheduled services that are sometimes forgotten.

Here is a list of 10 service items that are often overlooked by Herndon residents. They're all very important and need appropriate attention. So here we go, in no particular order.

1. Power Steering Service
Be honest; have you ever thought of this on your own? Your power steering fluid gets dirty and builds-up moisture over time. Cleaning out your power steering system means that dirt and gum are removed and your power steering parts are protected from corrosion. Next time you're in for an oil change, ask your McLearen Shell service advisor if it's time for a power steering check-up.

2. Wheel Alignment
When your wheels are out of alignment your vehicle pulls to one side. It's pretty annoying, but it's also dangerous. And it causes your tires to wear out really fast, which is an unnecessary expense! Most owner’s manuals suggest you get your alignment checked once or twice a year.

3. Differential Service
Did you even know you had a differential? Well, you do - one, two or three in fact. Differentials are often called gear boxes and they're part of the drive-train that transfers power from your vehicle engine to your wheels. They don't need service that often, but you can't completely forget them. Check with your friendly and knowledgeable McLearen Shell service advisor.

4. Cabin Air Filter
More and more cars these days have cabin air filters (a great feature, in my opinion) to clean the air in the passenger area where we sit. They filter out dust and pollen. When they're clogged up, they can get smelly. Change your cabin air filter on schedule to enjoy fresh, clean air, which can also help with allergies.

5. Timing Belt Replacement
Most cars and some vans and trucks driven around the Herndon area have timing belts. Without going into a lot of detail, let's just say that your car won't run without it – period. And if it breaks while you're driving, it can do thousands of dollars’ worth of engine damage. Check your owner's manual or speak with your McLearen Shell service advisor. If you're approaching 60,000 miles or 100,000 kilometers; definitely look into it right away.

6. Transmission Service
Transmission service is very basic, but it's often forgotten by Herndon drivers. Your vehicle transmission needs clean fluid from time to time to keep operating efficiently and avoid pricey repairs.

7. Air Conditioning Service
Most of us don't think about our air conditioning until it fails on a hot day in Herndon. If you're lucky, you just need to add refrigerant. If you're not, some of the components may have been ruined. Of course, these components are not cheap. Regular air conditioning service at McLearen Shell in Herndon adds clean refrigerant which cools and lubricates your air conditioner and conditions the seals.

8. Brake Service
No we're not talking about squealing, grinding brakes here. We're talking brake fluid. Over time, the fluid gets a lot of water in it. Because water compresses differently than the brake fluid, your brakes won't work as well. It may even get dangerous. The water can also rust out brake system components and then your brakes can fail altogether. Check with your McLearen Shell technician for recommendations.

9. Coolant System
Another thing that's so easy for Herndon drivers to forget about: When you don't change your antifreeze on schedule it becomes corrosive. Fresh coolant contains additives that maintain the pH balance in the coolant. These additives wear out and the fluid in the radiator can actually eat holes in the radiator or hoses. Then you're stranded - bummer.

10. Fuel System Cleaning
In these times of high fuel prices, fuel system cleaning is vital. Fuel gums up a bunch of parts as it moves from the gas tank and through the engine. A thorough fuel system cleaning at McLearen Shell in Herndon will keep clean gas flowing into the engine. Your fuel injectors also get gunked up over time and need to be cleaned. Having your fuel system cleaned on schedule at McLearen Shell will really help your fuel economy.

There you have it: 10 services that are often overlooked by Herndon residents. Did you know that a recent survey showed that 90 percent of vehicles on the road have at least one scheduled maintenance service that hasn't been performed? Considering our busy lives, we're not surprised. McLearen Shell can help with any of these services. Give us a call or come see us.

The McLearen Shell Guide to Vehicle Diagnosis

Modern Herndon vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions – and on some vehicles, even steering, braking and the throttle.

Think about that for a minute – things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their vehicle it can be pretty complicated for Herndon drivers to track down the source of the problem.

To help your service advisor at McLearen Shell figure out what's wrong, your vehicle is equipped with on-board diagnostics. The Check Engine light comes on to tell you there's a problem and the engine management computer stores a trouble code. Your friendly and knowledgeable McLearen Shell technician connects a scan tool to your vehicle's diagnostic port and retrieves the trouble codes as well as other important data.

Trouble codes are like clues for the technician to follow as he diagnoses what's wrong with your vehicle. In a way, it's like going to your Herndon doctor with a problem. She'll run some additional tests and gather the information she needs to make a diagnosis and form a treatment plan. How much a vehicle diagnosis costs at McLearen Shell in Herndon depends on how much time it takes to sort out the symptoms and find the underlying problem.

New Life for Your Older Car in Herndon

Isn't it amazing how much of our stuff is disposable these days? Clothes, electronics, housewares, furniture.

Remember the days when Herndon families mended their clothes, polished their shoes and neatly put away their toys every night? If something was lost or ruined through neglect, your parents just told you to do without, that you should have taken better care of it. They considered the loss a “life lesson.”

But today many Herndon drivers tend to neglect one of the more expensive and important purchases we make: our vehicles. Vehicles are a lot more reliable today than back when we polished our shoes, and that reliability can sometimes make us take them for granted. Drivers in Herndon neglect good vehicle care practices and procrastinate when it comes to preventive maintenance. What we're really doing is heading straight for one of those dreaded “life lessons.” Eventually we'll pay for our neglect in repair bills and a shorter life for our vehicle.

Is procrastinating on routine maintenance really so terrible? Consider what happens when you procrastinate on brushing your teeth, washing your clothes or getting the dishes done. Gunk builds up, makes the job harder and ultimately damages your teeth, clothing or dishes. It's the same with your vehicle. Some of the best auto advice out there for Herndon drivers is to stay on top of routine oil changes by bringing their car into McLearen Shell. Even a little extra interval between oil changes can result in oil sludge, which can clog passages in your engine. This means oil can't get to some of the engine components, and they'll wear out faster without lubrication. Every time you put off an oil change, the problem gets worse, eventually cutting years off the life of your engine.

The same is true if you skip cooling system service. Corrosion inhibitors in the fluid become depleted over time, opening the system up to damage. Consistent neglect will lead to holes in your radiator. Talk to your friendly service advisor at McLearen Shell for suggestions and feedback.

Neglect of other fluids can also result in engine damage. Brake fluid, transmission fluid, differential fluid—all of these need to be serviced on a regular basis. In addition, your fuel system needs periodic cleaning or it can start to break down and cause permanent damage to your engine.

The good news is that it's never too late to get on track and start getting good, regular preventive maintenance for your vehicle at McLearen Shell. You may not be able to reverse damage that's already been done, but you can prevent further damage.

It really does all start with an oil change. With a full-service oil change at McLearen Shell, your fluids will be checked and your car inspected for wear and tear. Our pros at McLearen Shell can also advise you of other inspections and maintenance items that are coming due. If you're on top of oil changes, your service advisor will keep track of your maintenance schedule and remind you what needs to be done.

Older vehicles are going to need repairs. But with good maintenance, those repairs will involve fairly routine stuff like alternators, water pumps, belts and batteries. The cost of these replacement parts at McLearen Shell is much cheaper than the repair bills that come with serious engine damage, and they're certainly less than the cost of a new car.

We may not need to polish our shoes anymore, and tossing out that outdated cell phone may not be such a loss. But when it comes to our vehicles, they're just too valuable to be treated as disposable. Let's take a step back, listen to our parents and take care of our stuff. If we don't, we could be on our way to a “life lesson” involving our bank account and a bus pass.
