Suspension Service At Hi-Tech Car Care

January 17th, 2012 by hitech09


  />  

Suspension systems will continue to operate effectively for many years and tens of thousands of miles. Eventually Car components do wear out, but how long that takes depends a lot on how you drive in Paradise Valley.

As you can imagine, if most of your driving is on smooth Arizona highways, your shock absorbers will last a lot longer than if you do most of your driving on bumpy roads or hauling heavy loads. In addition to just wearing out, Car suspension components can be damaged in an accident or by a hard impact – like a pothole, hitting a curb or a rock in the road. Because the life span of shocks can vary so widely, your Car manufacturer recommends periodic inspections.

Suspension Service At Hi-Tech Car CareDuring an inspection at Hi-Tech Car Care, your Trustworthy Paradise Valley service technician will check for worn, broken or missing parts. Let me give a rundown of the major suspension components.

First there are the springs. The springs hold the weight of the vehicle. There are several kinds of springs. Springs are obviously heavy duty parts that rarely break or wear out. Shock absorbers work in conjunction with springs to smooth out the ride and help keep the tires on the road. The shocks are key to handling performance and ride comfort.

You’ve probably heard of struts. They combine a shock absorber and a coil spring in one unit. Shocks and struts will wear out over time. There are some signs that shocks or struts are wearing out. The tires may have a cupped wear pattern. This is from the shocks bouncing unevenly. You may notice a floaty or drifting sensation when cornering. If the front of your Car dives excessively when stopping, or rocks back and forth after you stopped, your shocks may be worn out. And if they are leaking fluid, it’s definitely time to replace them.

If you are experiencing any of these symptoms, visit Hi-Tech Car Care for a suspension inspection. Same if you’ve been in an accident that involved one of your wheels. If your Car suspension actually fails, it could lead to a serious accident, so take care of these things.

When you replace your shocks, it’s usually a good idea to replace all four at the same time. That’ll give you more even handling. Talk with your Hi-Tech Car Care service advisor because you don’t want a big difference between the performance of your shocks from wheel to wheel, and replacing all may be the safest bet.

There different grades of shocks and struts. You always want to use a replacement shock or strut that equals the one that came as original equipment when your Car was new. But remember, they were designed to meet the expected needs of the broad range of Paradise Valley people who buy that particular vehicle. Your needs may be more specialized.

For example if you want increased handling performance for your Car, your Trustworthy Hi-Tech Car Care advisor can recommend an upgraded shock or strut to give you what you want. If you haul heavy loads or trailers, you can get a more heavy duty shock absorber.

Ethics of Automotive Repair in Phoenix

January 10th, 2012 by hitech09

We’re going to be talking about the ethics of automotive repair. It seems like news outlets really like hit-and-run reporting; they hit everyone from groceries stores to retail to physicians. And the Phoenix automotive service and repair industry hasn’t been given a pass either.

Unfortunately, every profession in Phoenix has some bad actors that hurt the reputation of everyone else. On the automotive side, industry associations and professional licensing organizations are very committed to high ethical standards.

Yet some people remain uncomfortable with Phoenix automotive service and repair. It may start with the fact that our vehicles are a big investment and we rely on them for so much in our lives. That alone guarantees our attention. And how well we understand the recommendations really impacts our comfort level.

If we understand what’s recommended and the benefits of taking care of the work – and the pitfalls of putting it off – we’ll have more trust in the recommendation. So communication is key. It’s like going to the doctor; If she’s using medical jargon and takes a lot of basic medical knowledge for granted, we have a hard time following her train of thought. It can be like that with your Phoenix service advisor too. He’s so familiar with all things automotive, he may forget you don’t know a PCV from an EGT.

If you don’t understand what your doctor’s talking about: ask some questions. If you don’t understand what your Phoenix automotive advisor’s talking about: ask some questions.

Let’s go back to those ethical standards; when we hear a repair recommendation, we always ask ourselves, “Is this really necessary?” Well, here’s the industry standard:

If a technician tells you that a repair or replacement is required it must meet the following criteria:

  1. The part no longer performs its intended purpose
  2. The part does not meet a design specification
  3. The part is missing

For example, it you take your car in for a grinding noise when you step on the brakes, you may just think you need new brake pads. After the inspection, the technician at Hi-Tech Car Care says that you have a cracked rotor and need to replace it.

If you tried to get him to simply put new pads on, he would say that if you didn’t want to replace the rotor; Hi-Tech Car Care would ethically have to refuse the repair.

To just put pads on a cracked rotor would have been very wrong. The brakes could’ve failed at anytime and needed to be repaired – not just have a band-aid slapped on them.

Now, looking at something not so serious, the technician may suggest repair or replacement if:

  1. The part is close to the end of its useful life – just above discard specifications or likely to fail soon
  2. To address a customer need or request – like for better ride or increased performance
  3. To comply with maintenance recommended by the vehicle’s manufacturer
  4. Based on the technician’s informed experience

Of course, the technician has the burden of making ethical recommendations and properly educating their customers. For the customer, if you are uncomfortable with a recommendation, ask some questions. More information is always a good thing.

Tire Replacement: What Paradise Valley Drivers Need to Know

January 3rd, 2012 by hitech09


  />  

Looking at getting some new tires? The choices at Paradise Valley tire stores can be a little overwhelming. Suppose you have an SUV and are trying to decide between all season tires or some that are also rated for off-highway. Do you get off the payment on the outskirts of Paradise Valley more than most? If so, some additional off-road traction would be nice.

Tire Replacement: What Paradise Valley Drivers Need to KnowMaybe the real reason for wanting those off-highway tires is that they look cool. Well there’s nothing wrong with that. If you make sure that you’ve got your functional needs covered with your selection, then you can have some fun with where you go from there.

Let’s suppose you zip around Paradise Valley in a sporty car. You may like to run a high-performance summer tire when the weather’s good. When Arizona weather turns cold, you can put on high-performance winter tires. For the kind of driving you like to do, you want full-on performance tires. All-season tires are naturally a compromise that works well for most Paradise Valley drivers, but since you have a choice, go for dedicated summer and winter tires.

When it’s time for new tires, visit with a knowledgeable Hi-Tech Car Care tire professional. Describe your needs and wants. He’ll come up with some selections for you to discuss. And once you settle on a type of tire, there are options for special needs: like pulling a trailer or carrying heavy loads.

Tires are one of the biggest purchases for Paradise Valley drivers. With so many choices, you’ll be able to get what’s best for you. Take their time. And don’t worry about what’s in stock. If you want something that isn’t here at Hi-Tech Car Care, manager Jim Garnand can order it. Chances are you’ll be rolling on your new tires in a couple of days.

Hi-Tech Car Care Maintenance Tips: The Belt Goes On

December 27th, 2011 by hitech09


  />  

Today’s Hi-Tech Car Care auto maintenance article focuses on your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems. Let’s go over them.

First, the serpentine belt drives your Car air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in Phoenix.

Next, the belt powers the alternator. The alternator creates electricity that’s used by your Car’s electrical systems and also charges your car battery. Hi-Tech Car Care Maintenance Tips The Belt Goes OnAll Phoenix drivers know that without the alternator, the battery will go dead in a few miles.

The serpentine belt may also run the pumps for both the power steering and power brakes. And, on many Cars, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures as you drive around Phoenix.

Now on some Cars, the water pump is powered by the timing belt instead of the serpentine belt. So you can see the serpentine belt does a lot of work. And it if breaks, it affects a lot of systems. That’s why manufacturers and your service advisor at Hi-Tech Car Care have recommended that it be changed every so often so that it doesn’t fail.

Your Phoenix service technician can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will measure the amount of belt material to make sure there is enough.

There’s a special, spring loaded pulley attached to the engine called the tensioner pulley. Its job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. At Hi-Tech Car Care, we recommend that the tensioner be replaced at the same time as the serpentine belt.

All in all, the serpentine belt’s an important part for the function of your Car.
And it’s not that expensive to replace in Phoenix – so it’s good to do so before it fails.

PCV Valve Service At Hi-Tech Car Care In Phoenix

December 21st, 2011 by hitech09


  />  

The PCV Valve is a little, inexpensive part that does a big job for Phoenix drivers. PCV stands for Positive Crankcase Ventilation.

The crankcase is the bottom area of the engine that holds the oil. When the Car engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel.
PCV Valve Service At Hi-Tech Car Care In PhoenixThis can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause Car engine corrosion, something we see occasionally at Hi-Tech Car Care. At high speeds on Phoenix freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, engine makers simply installed a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, laws mandated that these gases be recycled back into the air intake system to be mixed with fuel and burned in the Car’s engine.

This is much better for the environment and it saves gas too. (Budget-conscious Phoenix drivers take note!) The little valve that controls all this action is the PCV valve. The PCV valve lets gases out of the engine, but won’t let anything back in. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and wasted gas.

Fortunately, it’s very easy to test the PCV Valve at Hi-Tech Car Care and quick and inexpensive to replace. Even so, it’s often overlooked because many Phoenix drivers don’t know about it. Check your Car owner’s manual or ask your Hi-Tech Car Care service advisor. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

There’s another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That’ll need to be replaced at Hi-Tech Car Care when it gets dirty.

Please ask your Trustworthy Phoenix service advisor about your PCV valve. For the price of a couple of burger combo meals in Phoenix, you can avoid some very expensive deep engine repairs.

Hi-Tech Car Care Tire Safety: Washington vs. Lincoln

December 16th, 2011 by hitech09


  />  

Welcome to the Hi-Tech Car Care blog. Today, let’s talk about the effect of tire tread depth on braking. When talking about stopping power, most of us Tempe drivers tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough. Safe Tempe drivers need to have tires with enough traction to translate braking power into stopping power.

Hi-Tech Car Care Tire Safety Washington vs. LincolnLet’s focus on stopping in wet Tempe conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water.

That’s called hydroplaning. If it’s really bad, Tempe drivers can actually spin out of control. At best, you won’t stop as fast.

So how does a tire move water? It has channels for water to flow through. Look at your Car tire and you’ll see channels: channels that run around the tire and channels that flow across the tire. They’re designed to direct water away from the tire so it can contact the road better.

And the deeper the channel, the more water it can move. A brand new Hi-Tech Car Care tire has very deep channels and can easily move a lot of water. As the tire wears down, the channels become shallower and can move less water. When it wears down enough, it can seriously affect your ability to stop your Car on wet Tempe roads.

So that’s why it’s so important to replace our Car tires when they get worn. Consumer Reports and other advocate groups call for a standard of 3/32 of an inch and they have the studies to prove it.

By comparison, you’ve probably seen the wear indicator that’s molded into tires. When tires are worn 3/32 of an inch, the tread wear bar is visible. So the recommended standard has twice the tread depth as a completely worn out Car tire.

At Hi-Tech Car Care, we want our customers to know that the deeper recommended tread depth makes a big difference. Stopping distances are cut dramatically on wet Tempe roads. A safe stop from Arizona freeway speeds with 4/32 of an inch of tread would result in a crash with worn out tires.

There’s an easy way to tell when a tire’s worn to 4/32 of an inch. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your Car tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Many Tempe car owners have heard of this technique using a penny and Abe Lincoln’s head. That measure gives you 2/32 of an inch – half the suggested amount. Of course, Car tires are a big ticket item. Most of us in Tempe want to get as many miles out of them as we can. But there’s a real safety trade-off. It’s your choice.

Clean Air for Your Engine: Engine Air Filters In Phoenix

December 6th, 2011 by hitech09


  />  

Every Phoenix car owner who has taken their car in for an oil change has been told that their engine air filter’s dirty.

Here’s what goes into the determination of when to change the filter: First, your Car owner’s manual will have a recommendation of when to change the filter. Second, a visual inspection by your Phoenix technician may determine that your filter it is visibly dirty and needs to be changed.

Clean Air for Your Engine Phoenix Engine Air Filter

So between your owner’s manual and your Phoenix technician’s inspection there’s really no guesswork involved.

Now, most air filters purchased in Scottsdale, Paradise Valley, or Tempe don’t cost a lot to replace. It’s just that Arizona people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at Hi-Tech Car Care can often save enough on gas to pay for itself before your next oil change in Phoenix.

Think about a dirty furnace filter in your Paradise Valley home. When it’s all clogged up, enough clean air can’t get through. In your Car, that means that your engine can’t get as much air as it needs to burn the fuel efficiently. So it makes do with less air and has to use more expensive Arizona gas to move your vehicle around Phoenix roads.

Your Car actually needs about 12,000 gallons of air for every gallon of gas it burns. Engine air filters don’t cost much in Phoenix at Hi-Tech Car Care. When it’s time to change yours, just get it done. You’ll buy less fuel, have better performance and protect your engine.

Finding Vehicle Recall Information In Phoenix Arizona

November 29th, 2011 by hitech09


  />  

No matter how well they’re made, cars in Phoenix Arizona will have design or manufacturing problems.

And when the government thinks a problem is really serious for people in Phoenix Arizona, they require the manufacturer to issue a recall notice and fix the car free of charge. The manufacturer then tries to contact everyone in Phoenix Arizona who owns that type of car to get the recall work done.

These recalls always affect safety, so take them seriously. It’s easy to see if a vehicle’s being recalled.

Finding Vehicle Recall Information The government has links on its websites, or just visit AutoNetTV for links.

There are many websites with free recall information and searches. There’s CarFax, AutoByTel and the DMV.

Recalls are serious, but not all that common. But sometimes there are less significant issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like Hi-Tech Car Care how to repair a frequent or difficult problem.

The pros get updated information through subscription plans, also available in consumer versions for a reasonable cost.

So when vehicle recalls occur, get the work done, and keep you and yours safe.

Keep Your Cool In Phoenix: Air Conditioning Service

November 22nd, 2011 by hitech09


  />  

Most Phoenix drivers wait for their air conditioning to fail before they service it at Hi-Tech Car Care. That’s because many Phoenix and Paradise Valley motorists don’t really understand that automotive air conditioners need periodic service. Let me share some of the reasons why they fail.

First, like every machine, the Car air conditioner parts need lubrication. The lubricant is actually mixed in with the refrigerant (that’s the stuff that makes the air cool). So sometimes, even though the air conditioner is still making cool air, the oil that lubricates the parts has just been used up: and unlubricated parts can fail in all Arizona cars.

Keep Your Cool In Phoenix: Air Conditioning Service

Now here’s a tip for Phoenix drivers: You should run your air conditioner every so often during Arizona winters. This circulates the lubricant to help keep the seals from drying out.

The air conditioner actually removes some of the moisture in the air. So if you have trouble with fogging on your windshield during Arizona winters or during a rain storm, running the A/C on the defrost setting should help. Now on some Phoenix cars you can’t run the A/C at the same time as the defroster. Don’t ask me why, but I suspect lawyers were involved.

Also, air and water can get into the A/C system. That can reduce the efficiency of the system and also lead to corrosion that causes damage. Phoenix drivers should periodically purge the system and replace the refrigerant to clear out the air and water.

Phoenix drivers should be aware of early warning signs of trouble: One might be that the air’s not as cold as it used to be. You may hear an unusual noise when the A/C cycles on. Those are signs to get your vehicle into Hi-Tech Car Care in Phoenix before the damage gets worse.

So following the recommended service intervals in your Car owner’s manual can help prevent mechanical failure of your air conditioning system. You’re A/C system contains some expensive components like the compressor, condenser, dryer, etc. Anything Scottsdale and Paradise Valley car owners can do to lengthen the life of their A/C is well worth it.

Economics of Maintenance For Phoenix Auto Owners

November 15th, 2011 by hitech09

Buying a new car in Phoenix is always a big financial decision. The allure of that new car smell is powerful, to be sure. But what if your current car is still in good shape? How do you decide?

People in Phoenix who’ve been used to driving a new car every three to five years may be having second thoughts in this economy. For many, the question is, how does the certainty of a new car payment stack up against uncertain repairs for a car that may be out of warranty?

For purposes of our discussion, let’s assume you live right here in Phoenix and have a five year old vehicle. It’s now paid off. If you keep it, you fear that there’ll be some repairs over the next five years, but you really don’t know what to expect. For help we turned to Edmunds.com.

Edmunds.com has compiled maintenance and repair information for cars and trucks. With this data, they project likely service and repair costs for a particular make and model. They’re able to use manufacturer’s maintenance schedules and repair histories for the projections.

Of course, these projections can’t predict what will happen to your vehicle in Phoenix, but they do give you information to use in your decision.

Let’s look at the numbers for a five year old Toyota Camry V-6. In this example, the combined maintenance and repairs for the five year period is $5,748. This works out to an average of $96 a month. The year-by-year averages range from a low of $49 a month to $124 a month.

So compare $96 a month with a new car payment. And it’s actually better news than that; you would still have maintenance expenses with a new car, so the repair element could be less than half that figure.

Here are numbers for some other five year old vehicles from around Phoenix:

  • Ford Escape – $116 a month
  • Chevy Silverado – $131 a month
  • Jeep Grand Cherokee – $138 a month
  • Hyundai Accent – $85 a month.

Now, if your vehicle is older than five years, have a chat with your Phoenix service advisor at Hi-Tech Car Care. We see hundreds of vehicles through our bays every month and we know your car. See if there’s any particular problem common with your vehicle that you might see over the next couple of years.

And of course, the best way to keep future repair costs down is to take care of all your scheduled maintenance. This is especially important in older vehicles that have had time to accumulate some deposits.

There are special motor oil formulations that help clean older engines and protect and recondition their seals and gaskets.

We hope this eliminates some of the unknowns in the decision to keep or trade.
