"Current" Affairs (Blown Fuses)

You may be driving along and find that suddenly your radio stops working.  There are no numbers on the display.  Then when you get home, you notice the garage door opener doesn't do a thing when you press the button. Hmm, this was working just fine this morning.  Are the two problems somehow related?

No, your vehicle doesn't need an exorcism. This has all the signs of an electrical issue, and when you experience symptoms like those, you've probably blown a fuse.  Most vehicles have fuses just like most houses have circuit breakers (some houses still have fuses). They cut the power when it reaches a pre-determined threshold that could cause major damage if it was allowed to continue.  You might say fuses take one for the team.

Most modern automotive fuses are plastic with a thin strip of metal in them designed to melt when a calibrated amount of power passes through.  The philosophy is it's better for an inexpensive fuse to be destroyed than your sound system or your engine's main computer.

It can be tricky to figure out what fuse has blown and why.  Modern vehicles have many computerized electronic components; they can easily be damaged if too much electricity gets to the wrong spot.  At McLearen Shell in Herndon, we have technicians trained to trace which fuse has blown and why.

While sometimes a simple fuse replacement will fix the problem, other times there may be some other electrical component that has failed, causing the circuit overload.  Our technicians have special equipment to track down where the power problems are, get to the root of the problem and fix it at the source.

Keep in mind, fuses are there to protect your vehicle. And when they shut down your radio, garage door opener, vanity mirror or anything else, just be thankful they're doing their job. They may have saved you from a much more expensive repair. They've sent an important signal to you about your electrical system.  That's why it's good to keep up with "current" affairs.

McLearen Shell Service for Your Exhaust System

Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle.

The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important American Fork residents keep their exhaust system in good repair.

The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.

The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn't require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in VA. Call McLearen Shell at (703) 318-7744 if you suspect a problem with your catalytic converter.

Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the vehicle engine's computer keep the fuel-to-air mixture at optimal levels.

The muffler is also part of your vehicle exhaust system, but it deals with a different kind of emission. It keeps your vehicle from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.

It is important that damaged mufflers be replaced immediately at your Herndon automotive service center, especially if they are leaking. Not only will the extra noise annoy your Herndon neighbors, a leaky muffler could be serious.

The entire exhaust system is attached to your vehicle by hangers and clamps. These fasteners can rust, come loose or break. The components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.

Caring for your vehicle exhaust system at McLearen Shell yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.

Road Trip: Be Ready for Anything with a Trip Inspection at McLearen Shell

Road trip, anyone? Nothing spoils a great vacation faster than ending up stranded on the side of the road or spending a week in a rundown motel while our vehicle sits in the shop. Long days on the road can bring out the worst in your vehicle, so before you leave, prepare it for the journey by getting a trip inspection at McLearen Shell in Herndon. After all, you wouldn't travel without clean socks, why ask your vehicle to travel with a load of dirty oil?

The first step in a trip inspection at McLearen Shell is to look at your travel plans. What kinds of roads will you be driving on? Will you be in the VA back country or on the freeway? Will you be crossing mountains? Off-roading? What will the weather be like? How far away from Herndon will you be traveling? How much are you hauling? Will you be towing a trailer or lugging a rooftop carrier? Will you encounter dust, mud, snow or sea salt? All of these questions can help determine which services are most needed. And don't hesitate to ask your McLearen Shell service advisor. He can give you good auto advice on what trip conditions are hardest on what systems of your vehicle and what kinds of services it realistically needs. Start with the tires and check them for tread wear and proper inflation. Replace or rotate them as needed. If you need to change them out for winter tires, then do so.

Then look at your shocks or struts for wear. Replace them if needed. You'll want that extra comfort on your trip. Be sure to check your alignment as well. Steering a vehicle that is out of alignment is tiring, and dangerous. Don't overlook your brakes. With extra passengers and baggage, your brakes are going to get a workout. You want them in top condition.

In addition, inspect belts and hoses. If any of them are close to wearing out, have them replaced before your long trip does them in.

Change your engine air filter if it needs it, or if it's close to needing it. Your car's air filter processes 12,000 times as much air as the amount of fuel it burns. A clean air filter will protect electronic sensors that affect how your engine runs.

Get an oil change at McLearen Shell in Herndon if it's coming due. Make it a full-service oil change while you're at it. That way, all of your fluids will get checked and topped off. Change any dirty or old fluids. Herndon drivers don't want to overstress their cooling systems or transmissions with dirty fluid during a long trip.

Does your vehicle smell? Check the cabin air filter. The bad smell could also indicate an exhaust leak, which can be fatal on a long trip. So don't ignore bad odors; check them out.

If your air conditioning hasn't been up to snuff, then give it an overhaul. You want your vacation to be relaxed and pleasant, and that means keeping the passenger compartment comfortable.

And be sure to check your wiper blades and your headlamps. You may find yourself driving in unfamiliar territory at night after a long day. You'll want to be able to see as much as possible.

Of course, almost everything listed here is just part of preventive maintenance for smart driving. If you keep up with your vehicle care on a regular basis, a trip inspection will be a breeze at McLearen Shell.

Taking care of your vehicle before you leave for a road trip will pay you back in safety, peace of mind, improved comfort and better fuel economy. It will also help your vacation go as planned by keeping you on the road and headed for that next great adventure. Just don't forget to pack your socks.

Keeping Your Cool (Coolant leak repair)

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”).  Or maybe yours has a picture of a thermometer on it and a blue and red zone.  If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does.

One of the most common causes of an engine running hot is a leak in your cooling system.  Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on.

Your vehicle’s coolant can leak for several reasons.  You may have hoses that are deteriorating (heat and age take their toll). It’s possible the pump that circulates coolant has developed a problem (seals and bearings can fail from heat and wear).  You may have something as simple as a bad radiator cap.  Or your radiator or heater core may have holes in it. 

If your coolant is leaking out, this can cause serious damage to your engine if you just let it go.  Your engine could get so hot that some of the metal parts start to warp.  Sometimes, your coolant can start mixing in with your engine oil.  That can result in a very expensive repair if it gets to that stage, so have it checked out before that happens.

A technician will visually inspect your coolant system, including the reservoir tank, check hoses and fittings, test the water pump, and also may pressure test the radiator.  When the problem or problems are found, they will replace the necessary parts and get you back on the road. 

When it comes to a coolant leak, finding the cause can be tricky.  But it’s important to catch a cooling system issue in time—before your engine sustains more serious damage.  Now, that’s pretty cool.
