Battery Replacement For Your pickup

Modern cars and trucks in and around Tupelo run on 12 volt electrical systems. 12 volts is enough to get the job done for Tupelo car owners 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 MS car owners 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 Tupelo auto owners 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 pickup. 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 in the shop at Tupelo NAPA AutoCare Centers in Tupelo, MS. 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 Tupelo drivers working with their battery. Be careful to not spill acid on your clothes or the pickup’s paint. Of course, avoid short circuiting the battery as well.

Replacement car batteries come in all shapes and sizes. Some cars have limited space that requires a specially shaped battery to fit. Larger engines require more powerful batteries to get them started. If you live where it gets cold in MS you will need a more powerful battery because engines are harder to start when it is cold.

Sometimes there is quite a price range in Tupelo 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 money in the long run for Tupelo drivers.

Timing Belt Replacement in Tupelo

Today we want to talk to Tupelo auto owners about timing belts. They’re something that many Tupelo drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most Tupelo car owners remember because it’s not well understood.

Let’s review what a timing belt does. As most Tupelo car owners know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.

Now, not all Belden and Mooreville vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. The leading vehicle manufacturers started using belts rather than chains to save money in the manufacturing process. So now Tupelo auto owners and Tupelo NAPA AutoCare Centers technicians are left with a component that can break. They sort of shifted the problem to us. There are two broad categories of auto maker engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous for auto owners depending on where they are at the time, but it causes no internal engine damage.

Interference pickup engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost a chunk of money to repair the pickup engine.

So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from Tupelo NAPA AutoCare Centers may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the pricey damage it’ll cause. There’s no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Tupelo NAPA AutoCare Centers service advisor right away if your automobile manufacturer requires a timing belt replacement.

Sometimes Tupelo drivers can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.

What does it cost to replace a timing belt in Tupelo or Plantersville? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the expensive damage caused by a failure.

At Tupelo NAPA AutoCare Centers in Tupelo we’re all about trying to prevent pricey repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

Have You Checked Your Headlights?

Like everything on the Tupelo automotive market, there have been great strides in headlight technology in recent years. MS car owners can be safer at night because of it. Good headlights improve visibility on Tupelo highways, enabling you to see farther. They also improve your peripheral vision, helping you to see the sides more clearly. The more you can see, the quicker you can react to road conditions. This is critical because nearly half of traffic fatalities take place at night. And as Tupelo’s population ages, everything that helps older eyes is welcome.

Most new pickups sold in Tupelo come with halogen headlamps. A decade ago, halogens were exotic and expensive. Now that they are standard equipment, the price has come way down. Many luxury cars are equipped with high intensity discharge, or HID, headlamps. You have probably seen them on Tupelo highways, they’re very bright and have a bluish tint.

From behind the wheel, there is no doubt that HID headlamps are the best thing going. However, many Tupelo auto owners complain about HID lights in oncoming traffic or when they approach from behind. In fact, when the National Highway Traffic Safety Administration called for public comment, they received a record number of complaints about HIDs. This has lead to several studies – your tax dollars at work. Some expect future regulation of HID lamps.

All halogen headlamps dim over time. Your knowledgeable Tupelo NAPA AutoCare Centers service professional recommends that they be changed out once a year. AutoNetTV suggests you replace your headlamps in the fall at the end of Daylight Savings Time. It’s easy to remember – when you change your clock, change your headlamps. Remember to replace all headlamps at the same time – then all your lights will be equally bright. You will appreciate it during those long MS winter nights.

If you have an older pickup with old-school headlamps, you might be able to get a halogen replacement. You’ll be amazed at the difference this upgrade will make.

In addition to regular halogen lamps, Tupelo drivers can upgrade to premium lamps that filter some of the yellow light, making a bright white light that’s more like natural sunlight. This light’s easier on the eyes and should improve reaction time.

Now, you may be able to step up to HID headlamps, depending on the kind of car you drive around the Tupelo area. These lamps should last the life of your car, but cost several hundred dollars a pair. If you want other Tupelo auto owners to think you’re running HID lamps, you can even buy regular halogens that have a bluish tint. Does she or doesn’t she? Only her Tupelo NAPA AutoCare Centers service professional knows for sure.

Over time, plastic headlight covers can get cloudy or yellowed. In fact, AAA reports that nine out of ten headlights are dirty or yellowed, greatly reducing vision. In addition to helping you replace your headlamps, many service centers such as Tupelo NAPA AutoCare Centers in Tupelo, MS can restore headlight covers. Headlights can be restored at a fraction of the cost of replacing.

PCV Valve Replacement

The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Gasoline engines used to simply have a hose that let the poisonous fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. Diesel engines are not required to have these valves.

The positive crankcase ventilation, or PCV, valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It’s really a pretty simple system, but does an important job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil, but the engine as well. The PCV relieves pressure in the crankcase, preventing oil leaks.

Eventually, the PCV valve can get gummed up. Then it can not move enough air through the engine to keep it working efficiently. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation or surging or an oil leak, it may be a sign of PCV value problems. Your owners’ manual may give a recommendation for when the PCV valve should be replaced – usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some manufacturers don’t list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed with a visual inspection. Fortunately, PCV valve replacement is both quick and inexpensive. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your Tupelo service technician tells you its time to replace your PCV valve, you will know what he’s talking about. If you have had your car for a while and this is the first you’ve ever heard of a PCV value, ask your tech to check yours out or call Tupelo NAPA AutoCare Centers at 662.842.0036.
