While a bumpy road may be a minor nuisance to car drivers, a road littered with potholes can cause expensive car care auto repair / service costs to your car and even result in a car accident. Potholes are bowl-shaped openings in the road that can be up to 10 inches deep and are caused by wear-and-tear and weathering of the roads. They occur when the top layer of the road, the asphalt, has worn away and exposed the concrete base. Once a pothole forms, it can grow to several feet, with rain water accelerating the process.
We experience too many of these conditions just by driving our cars. Now, imagine that it is late at night, and there are no warning signs or overhead lighting. The speed limit is 40 miles-per-hour and, just before two cars meet, one car goes over a pothole, loses control and spins out directly in front of the other car driver and causes an auto accident.
Top-10 Worst U.S. Urban-Area Roadways For Potholes
New York City
With five major cities in the top seven, California residents will need to know about the dangers of potholes.
Potholes put a huge strain on your car’s suspension and shocks (which absorb most of the impact of bumps and potholes). It can cause expensive damage to your car and cause you to make an unexpected appointment with the auto mechanic. They can also cause an impact similar to that of a 35-mph car accident, if deep enough.
Sometimes, when a pothole is so severe, or your car is not equipped to handle the blow, it will cause you to lose control of your car. This leads to car accidents that, many times, have caused wrongful deaths. Motorcycle drivers are at special risk of injury if they ride over a pothole. Having just two wheels on the ground and a lower weight than cars, motorcycles are ill-equipped to handle potholes. Coupled with fewer safety features, motorcycle accidents caused by potholes are very deadly. Cars and truck are also at risk, as well, to get into an auto accident after running over a pothole.
Some Helpful Hints For Reporting Potholes To State Highway Authority
Give the exact location of the pothole.
Be prepared to describe it (length, width, depth).
Try to remember if you saw or heard rain water in the hole.
Ask if the hole in a bus route or on trolley or railway tracks.
It is always important to remember that, when dealing with potholes, you will have to expect the unexpected. Since a dangerous situation can arise out of nowhere, it is important to make sure that you are not speeding and are making safe decisions; otherwise, hitting a pothole could cause a car accident. Careful drivers have the best chances of avoiding car accidents. A careful driver will also be more likely to avoid an auto accident after hitting a pothole.
Although belts and hoses are still classified as expendable parts, their durability has increased to the point that many import shop owners and technicians are now neglecting to perform routine belt and hose inspections. From a historical perspective, belts and hoses have moved from a recommended replacement interval to an inspection interval. This means that, unless otherwise required, there is generally no recommended replacement interval for belts and hoses. The consequence of moving from replacements to inspections is that many shops are missing potential profits in belt and hose replacements.
TODAY’S BELT AND HOSE MARKETS
Just recently, I had a 2001 Asian import come in for a check engine light issue that illustrates what is happening in the belt and hose markets. Because the import wasn’t a popular brand in my area, many shops had turned down the diagnostics. So, after working with a vacuum schematic, I found the cause for the diagnostic trouble code to be a clogged vacuum line.
Of even more concern was that the owner was ready to leave on a long trip with a badly cracked alternator belt. The vehicle had just been “serviced” and, in the owner’s mind, was ready for his long trip. That wasn’t the case, however, because the belt was ready to shred its way off the pulleys within a few hundred miles of high-speed driving.
Unfortunately, in their haste to sell wiper blades and fluid flushes, many quick-lube mechanics overlook expendable items like belts and hoses. Although replacing the belt wasn’t difficult for a well-tooled tech, it would have been difficult for any repair facility that didn’t have the metric wrenches needed to fit under a tight-fitting intake manifold and power steering bracket.
The A/C compressor and power steering belt also had to be removed before the alternator drive belt could be accessed. Years of corrosion made removing the A/C compressor belt more challenging than it should have been, and an even greater array of tools was required to budge the tensioning pulley from its corroded mounting. Perhaps this example explains why many quick-service facilities give hose and belt inspection a relatively low priority on their service menus.
Belt inspections aren’t difficult. The first clue to a bad belt, for example, is a belt squeal heard during engine start-up. The second clue might be a belt squeal heard during parking maneuvers or during an alternator load test. The last clue is the fraying and cracking associated with a worn-out belt (See Photo 1). A frayed belt might indicate a pulley alignment problem, so it’s important to include some diagnostic time for inspecting and possibly correcting pulley alignment.
Many import manufacturers promote standards that might include the number of cracks per inch present on the inside of the belt. In addition to whatever standard might be published, I inspect the outside of the belt for signs of glazing or pulley slippage. If the original part numbers and markings are still visible, all is well with the belt and pulleys. On the other hand, if the belt is glazed or frayed, an idler or drive pulley bearing might be seizing up (See Photo 2).In most cases, any belt running past 100,000 miles might be running on borrowed time. Of course, many belts do last longer because of the variables that affect belt life, including the amount of torque transmitted by the belt, underhood heat, and exposure to oil and atmospheric ozone.
If, for example, the engine has separate accessory belts, the alternator belt will tend to crack and harden first because the alternator is continuously laboring to operate accessories and keep the battery charged. The air conditioning compressor drive belt might be the next to fail in warm climates. Here again, if the compressor is overcharged or is seizing up, belt life will suffer accordingly. Hydraulic power steering pump belts usually last the longest simply because they transmit maximum torque only under demand. Last, separate water pump belts transmit very little torque and are the most likely to incur the least wear.
Many years ago, the average water-cooled import had only four or five hoses including the upper and lower radiator, heater inlet and return, and a water pump bypass hose. In most cases, the lower radiator hose had a wire reinforcement to keep the hold from collapsing at high engine speeds. Imports built during the past several decades may have a dozen or more small coolant hoses that perform diverse duties, like heating the throttle plate assembly or warming up thermostatic idle speed controls.
In general, the upper radiator hose on a conventional cooling system is the first to fail because it endures the hottest coolant temperatures. The lower radiator hose, on the other hand, may operate at lower temperatures and, thus, may last much longer. The same can be said of the auxiliary hoses, including the heater outlet and smaller-diameter intake manifold hoses that have minimal exposure to underhood heat.
Hose inspections are relatively simple if, when the engine is fully warmed up, we begin by looking for any unusual swelling or seepage around the connection point of the hose. If the sides of a hose feel mushy or spongy at full operating pressure and temperature, the hose should be replaced (See Photo 3).
Similarly, if traces of coolant leakage are found around a hose connection, the hose has hardened and will likely leak if it’s reinstalled. If the cooling system is depressurized and the hose isn’t wire-reinforced, the radiator hoses can be evaluated by squeezing the sides together. Again, the rubber should feel firm to the touch. If the rubber feels soft or spongy, the hose is a candidate for recommended replacement. If the hose is so hard that it has lost its elasticity, it also becomes a candidate for replacement (See Photo 4).
WHEN TO SELL HOSES
Let’s face it: Because of the complexity of modern cooling systems, hose access issues and today’s relatively higher labor rates, it’s tough to sell a complete cooling system hose replacement. In many cases, a complete replacement isn’t absolutely necessary because most of the hoses might be in good condition. On the other hand, if a component like a heater core, water pump, radiator or engine is being removed or replaced, the only significant cost to the consumer is the cost of the hoses themselves.Keep in mind that re-clamping an old, hardened hose brings with it a potential liability issue. If you’re the shop that reinstalled that old hose, perhaps you’re not pursuing what is called “due diligence” in performing a reliable repair. If an engine is ruined because the old hose fails, you may not be following due diligence principle, at least not in the eyes of some legal experts.
BELT AND HOSE ESTIMATES
Economic times are tough, and it’s a demanding process to write an estimate for hose replacement that’s both profitable and competitive. Unlike other components, labor charges aren’t really an issue in many belt and hose replacements because belts and hoses must be removed to gain access to other components like a water pump, timing belt or the engine itself. Because the labor for belt and hose replacement is included in the replacement of another part in most labor guides, it simply doesn’t make economic sense to reinstall old, worn-out belts and hoses.It’s also important to emphasize to the customer how much more expensive it will be to replace the hoses at a later date when the issue of hose accessibility must be fully addressed. On some imports, accessibility issues might account for hours of additional labor time, not to mention the difficulty of performing a reliable installation within the confines of a tight engine compartment.
THE SECURITY ISSUE
Last, remember that having good belts and hoses is a security issue for most drivers. While having good belts and hoses on the family’s “beater” car isn’t a primary issue for most, having those new belts and hoses under the hood of their primary transportation becomes not only a security issue, but also a dollars-and-cents issue if the vehicle is stranded on a long trip due to a belt or hose failure.
Tech Tip: Make Sure You Have the Tools and Equipment Needed to Service Today’s Electrical Systems
By Mike DuBois
One day we are fat, dumb and happy using a piece of wire with a 12-volt bulb on the end of it to test things with. Now we are faced with deciding between using the 10 meg-ohm computer safe test light, the power injector or a logic probe complete with polarity protection, audible alarm, light and 20-foot memory cord. Geeesh! How did things get so confusing so fast? Progress my boy! That is the root of our problem here! As the cars and systems have gotten more and more complicated, so have the tools and equipment needed to work on those cars ….
Today’s professional technician is expected to be able to understand electrical theory, electronics, physics, as well as understand and interpret readings from complex electrical test equipment. Add to that volts and amps and ohms…OH MY!The good news is that there are some general classifications of electrical test equipment that can at least narrow down the choices to a more manageable number of tools to consider. There are generic system testers, there are specialty testers and there are diagnostic testers. These main three groups are a good starting place to think about the tools and equipment needed to test today’s modern automotive electrical systems.
Generic or general testers normally are designed to perform a range of tests or work on a variety of vehicles and systems. These testers might include such things as multimeters, battery load testers and voltage test lights. Again, the main thing about these tools is that they can work on different vehicles, and perform general tests on different systems.
This is the largest category of electrical testing tools and equipment. These tools provide the foundation for all the more complex testing that may be necessary later on. A technician will do well to start building his or her collection of tools here. The basics are still necessary even on the most complicated vehicles. The basics should include a 12-volt test light, a multimeter that is capable of performing a host of tests including the basics such as volts, amps AC and DC current measurement, diode testing, rpm, temperature and starter draw testing.
The meter should have overload protection via fuses, it should also be able to store min/max values on data, and meters that show a graphical representation are needed to perform many tests today. From here, a tech should consider a collection of ancillary items to support and complement the multimeter. These items might include an rpm inductive pickup, a K-style temperature probe and an amp clamp adapter (this allows for starter draw testing). Once these items are in place, make sure that the kit includes an assortment of test leads and extensions, back probes, clamps, etc. These items ensure that the technician can always hook his or her test equipment to whatever item is being tested.Another incredibly powerful tool is a power injector. These tools allow the technician to provide power to a component for testing. Most of these units have a ground wire available directly next to the power source. These tools are some of the best productivity tools in the current technician’s toolbox. These tools have features such as lights, audible alarms and polarity indication.
Specialty Test Equipment
Specialty testers such as oxygen sensor testers, ABS wheel speed sensor testers and fuel injection signal testers are designed to do one specific test. These tools are indispensable for verifying a diagnosis prior to replacing an expensive component. Many of these testers aren’t used every day, but on those occasions where you really need it, you will be glad you have it.
Diagnostic Test Equipment
This is some of the most expensive, complicated and powerful equipment and tools that a technician can purchase. The true value of this equipment is in the description. Diagnostic test equipment will actually provide the user with possible answers or diagnosis of what might be wrong with a vehicle. These tools are different from other test equipment in that they usually have the ability to receive, interpret and analyze multiple sources of data input.
One example of diagnostic test equipment is the latest generation of battery testing equipment. These tools are incredibly complex, they are using microprocessors and, in some cases, are performing multiple tests at one time to verify the condition of a battery. The early battery testers placed a load on a battery and then the user was left with making a decision based on the analog results of that test. Compare that with today’s testers, which are evaluating the battery on several levels including state of charge, voltage, amperage, percentage of life left, maximum potential power output and many other tests. This is just one example of a diagnostic tester used for electrical systems on today’s modern vehicles.Regardless of a technician’s knowledge level, picking test tools is not an easy task. Many times the testers that are available today are so complicated that even the professional sales and tool people can’t always know all the features and benefits of a specific tool or piece or equipment. The best course of action in those cases is for the technician to contact the supplier directly to learn more about the tool before making a buying decision. Another great way to learn about test tools is by attending seminars and continuing education programs. These are opportunities for the tech to see, touch and use the tool in a relaxed environment.

My automotive / car brake warning lights is on. What does that mean? Houston,Tx
If your auto backfires while starting (not while driving) usually one of a few things is the culprit. 1. Is it wet? Most commonly, this occurs in "damp" conditions and can be attributed to moisture in the distributor cap. The humidity in the air causes some condensation within the cap and interferes with the ability of the distributor to function properly. 2. Carbs and Fuel Injection. If your problem seems more general in nature and occurs other than in wet conditions, you likely have a problem with your fuel injection system or carbuerator. Depending on how your car is equipped (fuel injected or carbuerated) you will likely find your problem here.

My automotive / car brake warning lights is on. What does that mean? Houston,Tx
If the light is on all the time, it could mean you simply forgot to release the parking (emergency) brake. The brake warning light remains on when the brake is set as a reminder. If the brake warning light remains on when the parking brake is released, then something is amiss. In some cases, the brake warning light may remain on if the switch on the parking brake pedal or lever is misadjusted. Nothing is wrong with the brakes and a simple adjustment should fix the problem. If the brake warning light comes on when you apply the brakes, or is on continuously, it means that hydraulic pressure has been lost in one side of the brake system or that the fluid level in the master cylinder is dangerously low (due to a leak somewhere in the brake system). In either case, the fluid level in the master cylinder should be checked. Adding brake fluid to the master cylinder reservoir may temporarily solve the problem. But if there’s a leak, the new fluid will soon be lost and the warning light will come back on. Brake fluid leaks are serious because they may cause the brakes to fail! So avoid driving the vehicle until the system can be inspected to determine what’s wrong. Leaks can occur in brake hoses, brake lines, disc brake calipers, drum brake wheel cylinders or the master cylinder itself. Wet spots at hose or line connections would indicate a leak that needs to be fixed. Leaking brake fluid can also contaminate the brake linings, causing them to slip or grab. The uneven braking action that results may cause the vehicle to veer to one side when the brakes are applied. Brake shoes or pads that have been contaminated with brake fluid cannot be dried out and must be replaced. Brake Warning Light Circuit The brake system is divided into two hydraulic circuits. On most rear-wheel drive vehicles, it is divided so one circuit applies the front brakes and the other applies the rear brakes. On front-wheel drive cars and minivans, the system is usually split diagonally. One circuit works the right front and left rear brake, and the other works the left front and right rear brake. This is done for safety purposes so if one circuit loses all its brake fluid and fails, the vehicle will still have one remaining circuit to apply two wheel brakes. Usually located on the master cylinder or the brake lines exiting the master cylinder is a "pressure differential" switch. If either brake circuit develops a leak and loses its fluid, the difference in pressure when the brakes are applied will trip the differential switch causing the brake warning light to come on. Abs Warning Light On vehicles equipped with antilock brakes (ABS), a second warning light is provided to warn if a problem occurs within the ABS system. The ABS lamp comes on when the ignition is turned on for a bulb check, then goes out after the engine starts. If the ABS warning light remains on or comes on while driving, it indicates a fault has occurred in the ABS system. What happens next depends on the nature of the fault. On most applications, the ABS system disables itself if the ABS warning light comes on and remains on. This should have no effect on normal braking. Even so, ABS will NOT be available in an emergency situation or when braking on a wet or slick surface. CAUTION: If the brake warning light also comes on and remains on while the ABS warning light it on, it signals a serious problem. Your vehicle may not be safe to drive. The brakes and ABS system should be inspected immediately to determine the nature of the problem! If the ABS light comes on momentarily then goes out, the nature of the problem is usually minor and the ABS system usually remains fully operational. Some vehicle manufacturers call this kind of fault a "nonlatching" fault (meaning it isn’t serious enough to disable the ABS system). Regardless of the type of fault that occurred to trigger the ABS warning lamp, a special "code" is recorded in the ABS module’s memory to aid in diagnosing the problem. On some vehicles this code can be retrieved by putting the ABS system into a special diagnostic mode. The code is then flashed out through the ABS warning lamp. The code number refers to a diagnostic chart in a service manual that must be followed to pinpoint the faulty component. On other applications, a special "scan tool" must be plugged into the vehicle’s diagnostic connector to read out the fault code. Diagnosing ABS problems requires a fair amount of knowledge and expertise (as well as special equipment in many applications), so this job is best left to a competent professional.
