What Is Antifreeze?

by Leave a Comment

Antifreeze is the colored fluid, usually red or green, found in your radiator.  It can also be referred to as coolant and serves a few purposes.     What Is Antifreeze? The main purpose for placing antifreeze/coolant in your radiator is to keep the water that is in the engine from freezing in cold temperatures and boiling over in hot temperatures.  The engine of a car produces high levels of heat when it is running, the fluids flowing through the radiator system help to draw some of the heat away from the engine so it doesn’t overheat.  Antifreeze/coolant also has corrosion inhibiting chemicals that prevent rust build up that can take place in the engine of a car.  Radiators are usually filled with a 50/50 mix of water and coolant, since antifreeze/coolant doesn’t evaporate like water does it keeps the levels of evaporation to a minimum.   An added purpose of antifreeze is lubrication, it lubricates the moving parts it comes in contact with, like the water pump.

By properly servicing your car’s cooling system, (which includes changing the antifreeze at recommended intervals), you will help to avoid major engine problems.  If you wait too long to change the antifreeze/coolant, the used coolant can harm cooling system components because the corrosion inhibiting chemicals have been used up and are no longer able to do their job.  The idea is to change the coolant before the corrosion inhibitors reach dangerously low levels.

For regular antifreeze the vehicle manufacturers generally recommend coolant changes every 30,000 miles or every two to three years.  There are also “extended life” coolants that are designed to last 100,000 miles or five years.  But be aware that these “extended life” coolants only provide extended life when used in a clean system mixed with water.  If they are mixed with regular antifreeze or old antifreeze in a system, the corrosion protection is reduced to that of regular antifreeze.

If you are unsure as to whether or not the antifreeze/coolant needs to be changed you can have your service center test it to determine its condition.

Fall Tune-Up

As the kids are heading back to school, now is the perfect time to “tune-up” your car!  Since you will more than likely be chauffeuring your children back and forth from their fall activities or school, it’s a good idea to make sure your car is running  in peak condition.

The phrase “tune-up” is an old-fashioned maintenance term that only applies to older cars.  For today’s cars that are equipped with electronic ignition and at least one on-board computer which automatically adjusts fuel mixture, ignition timing and idle speed, ” engine performance maintenance” is a more accurate term.  But whatever you call it, it is necessary to have your car serviced at least once a year to maintain peak engine performance or restore the engine to its original operating efficiency.            

A tune-up is a process of inspecting, diagnosing, testing, and adjusting or replacing parts on your car that if left unchecked could cause decreased performance or other problems.  A basic tune-up includes removing and checking the spark plugs,  cleaning or replacing the spark plugs and installing them in the engine.  Your car’s distributor cap and rotor are checked for wear and cracks.  If there are cracks, moisture can get in and cause corrosion of the metal, which causes your car to misfire.  These parts should be replaced at recommended intervals or if they show excessive wear.  A tune-up also includes setting the idle speed to your car’s specifications.  These are the basic procedures performed during a tune-up but you can take this opportunity to have other systems checked out as well, such as brakes, clutch, fuel lines, hoses and belts.

The terminology used and services performed on our cars may have changed with time, but the importance of having your car serviced regularly hasn’t, so call your automotive technician and make an appointment for your fall “tune-up” today!

My “Check Engine” Light Is On, What Do I Do Now?

You are  driving along enjoying the ride and suddenly the “check engine” light comes on and you say to yourself, what do I do now?  There is a good chance that the problem is simple and easy to fix but to err on the side of caution is usually best.My Check Engine Light Is On, What Do I Do Now?

Before 1981, the dashboard indicators on cars monitored basic problems, fuel level, oil pressure and the temperature of the engine.   In 1981 federal clean air statues were instituted that required catalytic converters on all domestic cars and trucks to help reduce the level of pollutants in the air.  The computer that performs this emission system is called an on-board diagnostic (OBD) computer.  Then in 1996 the government required automakers to upgrade to OBD II, this is a sophisticated system of sensors that conduct diagnostic emissions tests as you drive.  When the OBD II detects a problem, your ” check engine” light goes on and the computer stores a “trouble code” in its memory that identifies the source of the problem.  These codes can then be read with an electronic scan tool or a diagnostic computer, which is standard equipment in auto repair shops.  Once the codes are read, they direct your repair technician to the source of the problem.

A “check engine” light can signal many different things, something as simple as a loose gas cap to a seriously misfiring engine.  So what do you do now?  First of all, you should read your owner’s manual and be familiar with your cars gauges and indicator lights and the purpose of each of them.  Some lights are yellow to give  you a warning, and some are red, meaning  a problem needs immediate attention!  Know what your dashboard is telling  you! Look for indicators of a serious problem that might require quick action.  Check the dashboard for indications of low oil pressure or overheating.  If either of these conditions exists, pull over and shut off the engine as soon as possible!

If nothing serious is indicated, check your gas cap and make sure it’s tight.  Sometimes a loose gas cap can cause the “check engine” light to come on, but the most important thing is don’t ignore it.  It doesn’t always mean a big problem or an expensive repair is ahead, but driving with the light on could end up damaging expensive components and causing further damage to your engine.  Have your vehicle checked by a trusted mechanic as soon as possible when the light goes on. That way you can avoid any costly repairs and that little “check engine” light has done it’s job!

Auto Repair: How Much Should It Cost?

by Leave a Comment

How many times have you gone into an auto repair shop for a repair that in your mind shouldn’t cost very much and then been shocked by the actual cost?  Auto repair isn’t cheap and we shouldn’t expect it to be. Auto Repair: How Much Should It Cost? The cost of repairing a  vehicle is based on several factors.   The make, model and year of the vehicle affect the cost of repairing it.  Lack of accessibility on some cars raises the cost.  Of course, type of auto repair needed determines how much it will cost.  Some repairs cost more because the parts involved are more expensive.  The cost of auto repair is also determined by the labor rates in your area.  The average shop charges between $60-$100 per hour for labor.  Finally, where you take the vehicle for repair affects the cost.  Dealerships usually charge more than independent repair shops because they have more overhead costs to cover.  As with all your auto repair needs, it’s important to look for a trustworthy shop that will give you honest advice, quality service and fair prices.

We can’t avoid auto repair!  Sooner or later, something is going to break, wear out or fail.  We can try to  prevent major repairs by good preventative maintenance but auto parts still wear out.  Most frequently, tires, brakes, belts and hoses.  And the more miles on your car the greater the possibility you may have engine or transmission problems.  Nothing lasts forever, so when your vehicle needs repair, you want to know how much it should cost before the work begins.  A reputable shop will give you an estimate that lists the parts that need replacing and their cost, the labor charged to replace those parts, any charges for diagnostic time (this covers the time it takes to connect a scan tool to your vehicle and read out any fault codes that may be in the vehicle’s computer) and any additional charges for miscellaneous items such as hazardous waste disposal fees, or shop supplies.

The labor you are charged is usually based on a standard “flat rate” and it most often the most expensive item on auto repairs.  The labor time required to perform a certain task will vary depending on accessibility of the part, the degree of difficulty of the job, and whether special procedures or tools are required to complete the job.  All of these are taken into account when a vehicle manufacturer or manual publisher determines the flat rate tables for various repair jobs.  This information is published and then used by repair shops in preparing their auto repair estimates.  The longer it takes a technician to replace a part, the higher the charge.  Auto repair is difficult, messy, back-breaking work that requires skill, training, and experience.  Cars today are just as technical as a PC, and when they crash, they’re just as costly to repair.  Most of us don’t expect to have our computers repaired for nothing but somehow we have the idea that  auto repair should only cost us pennies! Maybe it’s time to think again!

Cheap Oil Changes, Are They Worth It?

by Leave a Comment

During this economic crunch, we are all looking for ways to save money.  But when it comes to the condition of our cars, those valued objects that get us to our jobs, the grocery store, school and social events do we want to risk getting a cheap oil change?  Saving a little money now by using cheap oil can cost you a lot in the future when the oil fails to do its job.

There are two important things that oil does for your engine.  First it provides lubrication.  Inside your car’s engine there are many moving parts that would rub against one another, creating extreme levels of friction and wear. If these parts come into contact with one another without oil between them to create a cushion, there would be severe damage to your engine.  Without quality oil your engine’s performance is greatly  affected.  Your car won’t run smoothly and your gas  mileage will be much lower.    Secondly motor oil cleans the engine and prevents contaminates or “sludge” from building up.  Quality oil will contain detergents that help clean the engine and additives that help inhibit corrosion.Cheap Oil Change, Are They Worth It?

You might think that you are saving money by going to a shop that advertises a $19.99 oil change.  But in order to give you that price they have to sell you cheap oil and a low quality oil filter that doesn’t meet with manufacturer’s specifications.  When the cost of an average oil change is $35-$45 at a reputable shop that uses high quality oil and high quality oil filters and it’s recommended that you change your oil every 3 months or 3,000 miles, if you do the math that comes to 50 cents a day to change the oil in your car.  Most of us can afford 50 cents a day!  We spend more than that on our morning coffee!  If we skip one coffee trip a week and put that money toward our oil change, our wallets wouldn’t even notice! Considering all the benefits our cars provide when they run well, don’t you think it’s worth it?

When To Replace Your Timing Belt

by Leave a Comment

Some parts on your automobile are easy to see when they need replacing. The tread may wear down on your tires, or the fluid in your washer tank runs low. For other parts, its more important to maintain them on a regular basis based on an interval specified by your car’s manufacturer.

Replacing your timing belt is one such part. For most vehicles, your timing belt needs to be changed between 60,000 to 75,000 miles.

Your cars timing belt is a ribbed band of rubber and fiber that controls the timing of your engine’s valvetrain. In connects the crankshaft with the camshaft. It’s a necessary piece of your engine, and if it breaks, your car shuts down. Whether you’re at home, at work, or hundreds of miles from home on vacation, you’ll need to repair your car immediately after the timing belt breaks.

Your timing belt gives no indication of wear or impending failure – it simply snaps when you’re driving and leaves you stranded. While it may seem unfounded to change something with no problems, the alternative can cause you nothing but headaches.

In the case of replacing your timing belt, an ounce of prevention truly is worth a pound of cure.
