Relax When the Wind Blows in VA: Winter Car Prep for Herndon Drivers

When autumn comes around in Herndon, leaves fall, nights get longer and there's a definite nip in the air. Time to unpack the boots and gloves and fold some extra blankets onto the beds. It's also time for Herndon drivers to winterize their vehicles.

Here is some expert auto advice for Herndon drivers on what vehicles need to keep everyone safe and rolling throughout the VA winter months.

1. Check your antifreeze. Top it off or change it if necessary. You don't want your radiator, engine or hoses freezing up. If your vehicle isn't generating enough heat to keep you warm, your antifreeze might be low, or you might have a thermostat problem. Either way, you should get it checked out before the full force of VA winter sets in. If you are due for a cooling system service at McLearen Shell in Herndon, get that done as well.

2. Check your brakes. The slushy wet conditions of winter increase stopping distances. Ice exacerbates the problem. Your first concern, of course, is to make sure you adapt your driving habits to winter weather: slow down, and give yourself plenty of room to stop. Get your brakes checked at McLearen Shell and replace any worn pads or other parts. Check your brake fluid. It can accumulate moisture and decrease your stopping power.

3. Test your battery. A battery's cranking power drops in the cold, so if your battery is already weak, the onset of winter will do it in. The last thing you want is to be on a snowy VA road in the dark and cold with a dead battery.

4. Pack emergency supplies. Toss a blanket into the trunk. If you do find yourself stranded, your first concern will be to stay warm. If you're traveling away from VA population centers, then pack some emergency food and water as well. Also, it's a good idea to top off your tank in winter. That way, if you get stuck, you'll have some fuel to burn to stay warm, and it'll keep your gas lines from freezing up.

5. Check your wiper blades. They may be able to handle a light Herndon summer rain shower, but they might not be up to the ice and snow that collect on a windshield in winter. If you experience particularly harsh winters or really wet ones, you can purchase special blades that resist freezing. And don't forget to top off your wiper fluid.

6. Check your tires. Tires lose pressure over time, but they lose pressure fast when it's cold outside in Herndon. Tires lose about one pound of pressure every six to eight weeks; they also lose one pound of pressure for every 10°F/5.6°C drop in temperature. If the last time you checked your tires it was 80°F/26.7°C outside and it's 40°F/4.4°C now, your tires could be down five pounds in pressure — and that's serious. It's a safety issue and cuts down on your fuel economy.

7. Driving conditions in the Herndon area may warrant special winter tires. Check with your friendly and knowledgeable McLearen Shell tire professional to get the right tires for your area and for your driving habits. If you are getting winter tires, it's always best to get them for all four wheels. But if you're only going to get two, put them on the rear wheels, even if you drive a front-wheel or four-wheel drive vehicle. Traction is more important on the rear of a vehicle if you want to prevent sliding or fish-tailing on slick surfaces.

So there you have it: a quick checklist to winterize your car in VA. When it comes to car care, preventive maintenance is always the best practice for Herndon drivers, especially when it comes to winter weather. None of us want to be caught out in the winter cold.

Clean Fuel Equals Clean Performance for Herndon Drivers

Hello, Herndon residents. Let's talk fuel filters. Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the engine.

Herndon auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.

Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.

The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be serviced and how long you can expect it to last. Herndon drivers should change it before it becomes clogged. Your friendly and knowledgeable McLearen Shell service advisor can help you with recommended fuel filter replacement schedules.

Good vehicle care means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered in every owner's manual and have your vehicle regularly inspected at McLearen Shell. It may save Herndon auto owners money by preventing costly repairs, but it will also repay them in improved safety and peace of mind.

Battery Replacement for Your vehicle

Modern vehicles in and around Herndon run on 12 volt electrical systems. 12 volts is enough to get the job done for Herndon drivers without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks windows and sun roofs. And then us VA drivers have all the power outlets for our cell phones, computers and DVD players.

We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.

Fortunately, battery technology has given Herndon drivers resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over time. Eventually, every battery gets to the point where it cannot hold enough of a charge to start your vehicle. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak which makes it even more important to get it replaced.

Special safety precautions are taken when working with batteries at McLearen Shell in Herndon, VA. These precautions also apply to anyone who is poking around the battery. Batteries contain sulfuric acid that can damage your eyes and burn your skin, so safety glasses and rubber gloves are a must for any Herndon resident working with their battery. Be careful to not spill acid on your clothes or the vehicle's paint. Of course, avoid short circuiting the battery as well.

Sometimes there is quite a price range in Herndon auto part stores for batteries that will work in a particular car. Think of it as "good," "better" and "best." More expensive batteries have a longer warranty and are guaranteed to last longer. As with most things, paying a little more up front saves in the long run for Herndon drivers.

Drive Train - What You Need to Know in Herndon

One Herndon automotive service issue that doesn't get much attention is driveline service. Drivelines don't get talked about very much around Herndon, but they're very important. First let's define what the driveline is:

Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.

That's not really a lot of components, but they handle the full force of the engine. Without the driveline you're not moving. So Herndon residents need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we're going to have to oversimplify a bit.

If you are ready to have your drive train looked at, give us a call at (703) 318-7744.

Let's start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.

So, McLearen Shell driveline service would include properly servicing the transaxle and inspecting the cv boot to see if it's torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner's manual, or check with your friendly and knowledgeable McLearen Shell service advisor.

On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Herndon have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. Most Herndon residents have probably heard the term 'u-joints.' These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected at McLearen Shell in Herndon.

The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axle is damaged or leaks, the axle will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner's manual or Herndon service advisor for intervals.

Now let's go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The vehicle may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.

Some all wheel drive vehicles are designed to work well off-road in Herndon, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don't work well on dry pavement when they're in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.

Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is recommended as well as service to the center and rear differentials.

Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There's a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So Herndon residents need differential service for the front and rear differentials and for the transfer case as well.

The bottom line for Herndon residents is that the maintenance schedules are in your owner's manual. Your Herndon service advisor can answer any questions you've got. If this is the first time you've heard some of this stuff – it's time to ask someone at McLearen Shell if any of it needs to be done now.

Nighttime Visibility in Herndon

There are a number of factors that contribute to the high nighttime accident rate in the Herndon area, things like drowsy driving and a higher rate of impaired driving. Without a doubt, visibility is a major contributor. Let's focus on visibility…

It's said that 90 percent of our driving decisions are based on what we see. Nighttime driving has the effect of reducing 20/20 vision to the equivalent of 20/50 vision. What you could clearly see at 50 feet in daylight can't be seen until you are just 20 feet away at night.

Too make sure your headlights are giving you the greatest visibility, visit us at McLearen Shell, located at 3043 Centreville Road, Herndon, VA 20171. Please give us a call to make an appointment: (703) 318-7744.

Accident avoidance is dependent on reaction time. Reaction time deteriorates measurably in low light conditions. One thing we can do to improve visibility is to make sure our headlights are as bright as they can possibly be.

Headlamps dim over time. They dim so gradually that you may not notice it. Many experts suggest replacing your standard or halogen headlamps once a year.

If your vehicle has standard headlamps, consider upgrading to halogen lamps. They make a big difference. And there are upgrades available within the halogen category as well. This once-a-year expense is very modest compared to the safety benefits.

Some vehicles come with high intensity discharge – or HID – headlamps. These lamps should last for the life of your vehicle. They are very bright and are clearly the best option for nighttime driving. Depending on your vehicle, you may be able to upgrade to HID headlamps. Talk with your Herndon area service advisor at McLearen Shell about options for your car.

Another startling fact is that 90 percent of vehicles on the road have dirty or yellowed headlight covers. Dirty is easy to fix. Just run the window washer over the headlight cover when you stop for gas. Get those bugs and dirt off the cover.

Now plastic headlight covers can yellow or become hazy over time. They can be restored to clarity with a special polishing process. Our pros at McLearen Shell can help you with this service.

It's also vital to keep your windshield clean and streak free when driving at night. Make sure you have plenty of washer fluid and that your windshield wipers are in good working order.

We recommend replacing wiper blades twice a year – in the spring and fall. Fall is also a good time to replace headlamps so you'll be ready for those long winter nights.
