Keeping Your Engine Cool In Stoneham Massachusetts

January 24th, 2012 by lom004


  />  

The cooling system keeps our engine from overheating while you are driving around Stoneham Massachusetts. Its job is to move heat away from the engine. Let’s talk about the various components of the system and how they work to accomplish this.

The radiator is the part most everyone associates with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there’s enough airflow over the radiator, a fan pulls air over the cooling fins even when the car is idling.

In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your car off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

Stoneham Massachusetts Radiator A hose connects the radiator to the water pump. The water pump pushes the water into the engine block. Now the engine block and cylinder heads have passages for the coolant to pass through without getting into the oil or the combustion chamber. These passages are referred to as the “water jacket”.

While the coolant is passing through the water jacket, it absorbs heat from the engine on its way to the radiator for cooling. Between the engine and the radiator is a gatekeeper called the thermostat. The thermostat’s job is to regulate the temperature of the engine just like your home thermostat regulates the temperature of your house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

When your first start the engine, it’s very cold and needs to warm up. So the thermostat blocks the flow of coolant to the radiator. As the engine warms up, the thermostat starts to let coolant flow through the system.

The final component I want to talk about is the overflow reservoir. This bottle is designed to hold some of the coolant. It’ll have a mark that indicates whether or not you have enough coolant. This is where you should add coolant if you just need to top it off.

Caution: never open the reservoir or the radiator cap when the car’s hot. The cooling system is pressurized and opening them while it’s hot can cause hot coolant and steam to escape resulting in serious burns.

Cooling system failure is the most common mechanical failure in vehicles around Stoneham Massachusetts. Your Stoneham Massachusetts service center can do a periodic inspection of the components for leaks, loose connections and weakening hoses.

Your manufacturer has also specified a cooling system service interval. With a cooling system service, the old coolant is replaced with correct clean fluid that contains the additives required to prevent corrosion. The additives are depleted over time and you need fresh fluid for adequate protection. Your radiator pressure cap should be replaced at this service as well.

On Board Diagnostics For Stoneham Motorists

January 19th, 2012 by lom004


  />  

Some Stoneham motorists are confused by Hometown Automotive charges for diagnostic services for a vehicle repair. Many services at Hometown Automotive and other Stoneham automotive repair shops include diagnostic fees.

When you take your laptop into a Boston computer repair shop for a problem you’ll likely have to leave a deposit for diagnostics. When we visit our Woburn doctor for a medical problem, we’re paying him to diagnose our ailment and of course for the tests that go along with it.

On Board Diagnostics For Stoneham Motorists

So receiving a diagnostic charge at Hometown Automotive for a tricky automotive problem shouldn’t be a surprise. In the Boston area, automotive diagnostics can cover quite a range. If you hear a noise in your sedan brakes when you slow down in rush-hour traffic on a busy Massachusetts expressway, you pull off the next off-ramp and take a quick visual check. That is usually enough to know what needs to be done. If you’re having an intermittent problem with your sedan engine, Hometown Automotive diagnosis may be much more involved.

Much of the Boston public’s confusion comes when the problem involves the check engine light. The check engine light comes on when the engine management computer has sensed a problem.

There’s a common misconception among Woburn, Wakefield, and Melrose drivers that the trouble code tells the Hometown Automotive technician exactly what’s wrong. Why then is there a diagnostic charge, the scanner just gave the diagnosis?

Reality is more involved than that. The computer monitors many sensors throughout the vehicle. When one of these sensors has a reading that’s out of parameters, the computer will record a trouble code and turn on the check engine light.

The sedan computer’s trouble code just tells the Hometown Automotive technician what engine parameter is out of range – not what’s causing it. The technician needs to determine the underlying problem that’s causing the symptom.

There are many problems that could cause a troublesome sensor reading for Hometown Automotive Stoneham customers. The Hometown Automotive technician makes a list of the most likely causes and begins tracking down the source of the problem.

Boston service centers subscribe to databases that document possible causes for a given trouble code. They outline procedures for confirming a diagnosis and provide the documented fix. These databases are specific to each vehicle and engine combination.

Some diagnoses are quick and easy. Others are more involved and difficult. Of course Hometown Automotive wants to figure out what’s wrong with your sedan and get you back on the road as quickly as possible.

Wheel Bearings

January 12th, 2012 by lom004

Let me start by saying that your wheel bearings keep the wheels on your vehicle. Did that get your attention? In this article we’ll discuss more about wheel bearings and how you can keep them doing their very important job while you drive around Woburn Massachusetts.

Come see us at: 32 Pine st Stoneham, Massachusetts 02180

Wheel bearings are pretty simple parts. They’re made of high quality steel and are engineered to last 100,000 miles or more if properly cared for. The bearings do two very important jobs: First they allow the wheel to freely rotate with as little friction as possible. Second, they support the weight of the vehicle. For example, if your car weighs 3,600 pounds, each wheel has to support approximately 900 pounds. That’s a lot of heavy lifting over many, many thousands of miles.

Even though wheel bearings are relatively simple, they need to be in near perfect condition to do their job. The bearings are packed with heavy grease to lubricate and protect them. A seal keeps the grease in and water and dirt out. It’s when the seal starts to leak that problems begin. The grease can become contaminated; causing the wheel bearings to overheat and ultimately fail.

The first sign that your wheel bearings are in trouble is an unusual noise coming from a wheel. It could be a chirping, growling, rumbling or a cyclic sound. The noise could get louder or even disappear at certain speeds. Your technician at Hometown Automotive can inspect for bearing wear by lifting the vehicle and checking for play in the wheel.

Now some wheel bearing assemblies are factory sealed. That means that they cannot be serviced – they can only be replaced. Those that aren’t sealed can be serviced on schedule. The bearings are removed, cleaned and inspected. If the bearings are still good, they’re re-installed – if not, they’re replaced. They are then packed in grease and a new seal is installed.

If your vehicle has a factory sealed wheel bearing assembly, the entire assembly needs to be replaced when trouble arises. Unfortunately, the parts are pretty pricy – but they usually last about 150,000 miles as long as the seals hold up.

Now, even a good seal cannot keep out water that’s exerting pressure on the seal. So if you’ve driven through hub deep water your bearings should be cleaned and repacked if they’re serviceable. If you have factory sealed bearings, you just need to watch for signs of premature failure.

If your wheel bearings can be serviced, your owner’s manual will recommend an interval, usually around 30,000 miles.

Now, if you have any sort of trailer, don’t forget its wheel bearings. They probably need to be serviced even more frequently. This is especially true for boat trailers that are used to launch the boat by backing it into the water. These should be serviced every year, usually at the end of the season so that the bearings don’t have the opportunity to sit and rust all winter.

So what happens if wheel bearings fail? Well, the wheel can literally fall off the vehicle. I don’t need to tell you how bad that could be. So check with your service advisor at Hometown Automotive and see if your vehicle’s wheel bearings can be serviced and when it’s recommended. Listen for warning signs. If you’ve been fording streams or puddle surfing after rainstorms, be especially vigilant.

Come by Hometown Automotive for a wheel bearing inspection, or for tires. Call for an appointment at 781-279-0220

Tire Tread Depth for Stoneham Massachusetts

January 5th, 2012 by lom004

So, when are your tires actually worn out? This is a question a lot of us in Stoneham Massachusetts ask ourselves. For many, the answer is ‘when they no longer pass a safety inspection’. But waiting that long can have a serious impact on your safety.

The U.S. Federal government doesn’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Hometown Automotive (just call 781-279-0220) to find out what your requirements are in the Stoneham Massachusetts area.

Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give you enough safety?

Well, Consumer Reports issued a call to consider replacing tires when tread reaches 4/32”. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the big issue is braking on wet surfaces.

We tend to think of the brakes doing all the stopping, but you also need to have effective tires to actually stop the car. When it’s wet or snowy in Stoneham Massachusetts, the tread of the tire is critical to stopping power.

Picture this: you’re driving over a water-covered stretch of road. Your tires actually need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is actually contacting the road and not floating on a thin film of water – a condition known as hydroplaning. When there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.

This is where the studies come in. We think you’ll be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up truck were brought up to 70 mph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32” of tread were tested – this is the depth suggested by Consumer Reports

When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph with the worn tires.

Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph at the point where new tires brought the car to a halt. That’s a big improvement – you can see why Consumer Reports and others are calling for a new standard.

Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile of clear road ahead to come to a safe stop. Obviously this is really a big safety issue.

The tests were conducted with the same vehicles, but with different sets of tires. The brakes were the same, so the only variable, was the tires.

So, how do you know when your tires are at 4/32”? Well, it’s pretty easy. 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 tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Now you may remember doing that with pennies. But a penny gives you 2/32” of an inch to Abraham Lincoln’s head. The quarter is the new standard – 4/32”.

Tires are a big ticket item and most people in Stoneham Massachusetts want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out? For us, and we would guess for many, the answer is “no”.

Well, Mr. Washington, let’s go out and look at my tires.

The Fallacy of Cheap Tires

December 28th, 2011 by lom004

Do you ever shop for shoes in one of our Boston area shoe stores?
When buying a running shoe, is quality important?
Does durability matter as long as the shoes look fabulous?
Would you rather have one pair of long lasting shoes or two pair of lower quality shoes at the same price?

Is the warranty important when buying tires?

When you choose new tires in Stoneham, what’s the most important factor for you?

Give us a call at Hometown Automotive at 781-279-0220 for tire recommendations.

You know, buying tires in Stoneham is a big deal. It’s a big ticket item so you know you’ll be spending a lot. You’re not only concerned about the price, but you want to know that it’ll be a long time before you need to buy new tires again.

And of course there’s the safety aspect as well. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. They need to be up to the task. You want to be sure they hold the road and provide good traction. If you carry heavy loads or tow a trailer, the tires need a high load rating to be up for the job.

As a tire professional, I think it’s important that people understand the effect of price on a tire’s performance and durability. When I was a kid, my dad had a saying. He said, “Pay twice as much and buy half as many”.

Dad applied that to a lot of things. He thought that one high quality suit would last longer and look better than two cheap suits. The saying really seems to hold true when it comes to shoes and boots, too.

I buy high-quality work shoes because I spend a lot of time on my feet. They’re more comfortable, have important safety features like steel toes and non-slip soles – and they last at least twice as long as cheap shoes. I feel I get very good value for my money.

I apply the same thinking to tires. The major tire brands that you’re familiar with are known as Tier 1 tires. These tires are well-engineered and very high quality. Comparable tires are usually in the same price range from brand to brand.

Stepping down in price you come to private label tires. Some large tire store chains carry tires with the chain’s own brand. It’s important to know that most private label tires are built by the same Tier 1 brands that you are familiar with – so they are a quality product. You can ask your tire professional who makes their private brand.

The lowest priced tires on the market are Tier 3 tires. These tend to be imported from China or South America. Since you get what you pay for, you can’t expect a Tier 3 tire to deliver the same performance and durability as the others.

So let’s say you need new tires. You’ve determined the features you need. So you have several options, including price options. Now, you’ve probably heard the term ‘it’s a 40 thousand mile tire’ or ‘it’s a 60 thousand mile tire’. Simply put, the manufacturer warrantees the tire for ‘X’ number of miles. If that’s important to you, look for the warranty.

What’s the difference in the tires with higher mileage warranties? It’s the rubber compounds and the amount of tread material. As you might expect, you’ll pay more for the longer-lasting tire.

Now the cheapest tires you can find won’t have a manufacturer’s mileage warranty or if it does, it’ll be relatively low. That brings us back to dad’s saying; if you buy the cheapest Tier 3 tire you can, you will likely go through two sets in the time it would take to wear out one set of good quality tires. And the good tires won’t cost twice as much, so you’ll end up paying more per mile driven with the cheap tires.

Hey, I realize that sometimes the budget will only allow for a Tier 3 tire. I make them available for my customers who need them because I would rather see them driving with safe, new tires than pushing their old tires beyond their safety limits. But I always counsel my customers to buy as much tire as they can afford, because it will be much less expensive in the long run.

Your tires are the only part of your vehicle that touch the road. You’re only as safe as your tires are well built.

Buy value – not price.

Fuel Saving Tip: Tire Pressure Saves Fuel In Woburn

December 21st, 2011 by lom004


  />  

Under-inflated tires waste gas for lots of folks in the Woburn area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don’t have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from Stoneham to Woburn.

Stoneham Tire Pressure Always check your tire pressure when you gas up at one of our local Woburn service stations. If they’re low – even just a little bit – bring them up to proper pressure. There’s a sticker on the inside of your driver’s door that gives the manufacturer’s recommended tire pressure.

And don’t rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops twenty percent below recommendations. That’s severely under inflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Hometown Automotive.

Get some air and save some gas.

Protecting Your sedan From Theft In Stoneham Massachusetts

December 7th, 2011 by lom004

Every car in Stoneham Massachusetts is at risk for theft. So it’s up to us to make our cars a less appealing target and more of a challenge – hopefully sending potential thieves to look elsewhere.

The National Insurance Crime Bureau recommends a layered approach to protecting vehicles:

  1. Common sense
  2. Visible and audible devices
  3. Immobilizing devices
  4. Tracking devices

Let’s review each of these. First, common sense: you would be surprised how many vehicles are stolen from Stoneham Massachusetts where the keys were left in the ignition with the doors unlocked. Always take your keys, and lock the doors. In fact, in some places it’s against the law to leave a vehicle unattended with the keys in the ignition.

And don’t leave spare keys in the car or hide them outside – because a thief will find them. Try to park in well-lit areas that have a lot of foot traffic. If possible, park near the end of a row and near a light. Back your car into a parking space or your driveway to make your car more visible to passersby and harder for a thief to work under the hood without being seen.

Remember to roll up your windows completely and avoid leaving your car in public lots for a long time. If you park in a lot that has an attendant, only give them the ignition key.

Keep valuables out of sight: purses, wallets, cell phones, clothes and even change are attractive “smash-and-grab” targets. And pay to have your Vehicle Identification Number, or VIN, etched into your windows – it makes your car less attractive to a thief who wants to send your car to a chop shop.

There are lots of visible and audible devices available. A steering wheel lock is highly visible and will deter some thieves. Loud alarms can alert you and others that your vehicle is being tampered with. But if your alarm does go off, be careful. Observe what’s going on; get descriptions of suspicious people and vehicles, including license plate numbers.

Now, if you catch a thief in the act, call 911 but don’t approach the person. Your safety is more important than the car.

And here’s a great one – immobilizing devices. They actually shut off your car’s electrical or fuel supply. So without a key, or knowing where the hidden switch is located, a thief can’t drive your car away.

Finally, you can also get a tracking device that allows police to track your car down and recover it quickly.

Remember, where you live, work and drive around Stoneham Massachusetts has a great impact on your decisions. If you’re in an area with high theft rates, you may want to spend more money on security systems. And check with your Stoneham Massachusetts auto insurance company to see if they offer discounts for adding any of these items.

Of course, the common sense suggestions from Hometown Automotive don’t cost anything and go a long way toward keeping your car safe from thieves. Take a look at the attached video auto tip from AutoNetTV.

Keep Your Stoneham Car Breathing Free: Engine Air Filter

November 29th, 2011 by lom004

This is something really amazing: For every gallon of gas your Stoneham car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean.

That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed.

Dusty conditions in and around Stoneham or polluted city driving means you’ll need to change your filter more often. Your Hometown Automotive technician can check your filter for you. In fact, it’s often a routine part of an oil change.

When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your car needs this air to efficiently burn its fuel, giving you better fuel economy and performance.

Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.

So have your air filter checked. If it needs replacing, it doesn’t cost very much and it should easily pay for itself in better fuel economy before your next oil change.

Stop by Hometown Automotive at 32 Pine st, Stoneham, Massachusetts 02180, and we’ll take a look at your air filter for you. Feel free to give us a call at 781-279-0220 to make an appointment.

Fuel Injector Cleaning In Woburn, Wakefield, and Melrose

November 22nd, 2011 by lom004


  />  

In very simple terms, a fuel injector is a valve that squirts fuel into your sedan engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Woburn, Wakefield, and Melrose roads.

Fuel Injector Cleaning In Woburn, Wakefield, and MelroseMost fuel injectors for gas engines are known in the Boston auto industry as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few auto makers have recently introduced gas direct injection systems on some engines. They are now available at some Boston dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved fuel economy for gas-poor Woburn, Wakefield, and Melrose commuters. Massachusetts motorists can expect to see more of it in the future.

High temperatures
under your sedan hood and variations in Boston gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel economy and loss of power. So it’s important for Stoneham drivers keep their fuel injectors clean.

Your Stoneham Hometown Automotive service center can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your sedan fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Boston repair bills down the road.
