Keeping Your sedan Young
Posted February 1, 2012 11:38 AM
Sometimes it seems in Denver we live in such a disposable society. It's amazing all the stuff we throw away.
New stuff comes out so fast, we just toss the old and move on. It seems like when we were kids in Denver, our parents were real sticklers about taking care of our stuff. You know, hang up your clothes, polish your shoes, put away your toys. If something got lost or ruined by neglect, tough, we had to do without.
We couldn't afford new cars very often, so we tried to make them last as long as we could. It's a good thing that cars are more reliable these days. They just don't break down as often. And the good news for us Denver penny pinchers is that a modern car can easily go 200,000 miles with proper care. The engineering's there and so is the manufacturing quality. The missing ingredient is us making sure we follow the manufacturer's recommended maintenance schedules.
Is it really that bad to get off schedule? Well, it all adds up. Every time you go a couple thousand extra miles between oil changes, you've created an opportunity for sludge to form and clog passages. Then some parts don't get oiled and they start to wear out faster.
Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. The same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.
It's also even more important for older vehicles in the Denver area. Those engines and other systems have had more time to get dirty, so they're a bit more stressed anyway. But it's never too late to get back on track with your maintenance and to hold off further damage.
It's just another example of our parents being right. (Surprising how often that happens.) And it really does start with the oil change, just like Dad said. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. That's like your safety net; go in for oil changes on time, and let your service advisor at Downing Street Garage in Denver help you keep track of the rest.
Of course, some things are going to wear out along the way, stuff like alternators, water pumps and such. But that stuff is cheaper than a new car payment. And taking care of problems early means they have less time to cause other problems. It's like having high cholesterol; you don't want to wait for a heart attack before you address it.

Tire Rotation and Balancing
Posted January 25, 2012 11:31 AM
Tires do a lot of work. They transfer engine power and braking forces to the road; they handle steering control; and they cushion all those bumps and jolts. They also support the entire weight of the vehicle, including you and your passengers. With such critical work to do, you want your tires to do their job well. And since replacing tires is fairly expensive, you want them to last as long as possible.
There are three keys to long, even tire wear:
The front tires on a car take the brunt of the steering forces. As they push through turns, the shoulders of the front tires wear down more quickly than the rear tires. Rotating front and rear tires allows them to all wear at about the same rate. That’s especially true of front wheel drive vehicles whose front tires steer, and put the power to the road.
SUVs and pick-ups, especially four wheel drives, also tend to wear their tires more unevenly than cars because of their suspension and drive train set-up. Your owner’s manual will likely contain a schedule for tire rotation. It’s usually every 5,000 miles or so.
Also, there are different rotation patterns for different vehicles. Downing Street Garage will know which is right for your vehicle. That brings us to wheel balancing. When wheels are balanced, they spin on the axle evenly. When they are out of balance, they wobble a bit. That makes the tires wear unevenly and may transmit a vibration to the car. Your service technician at Downing Street Garage puts weights on your wheels to balance them out so that they turn true and smooth.
Tires are a big investment for any vehicle. They’re critical for keeping you safely on the road. The cost for regular rotation and balancing is more than made up in extended tire life. And, can you really put a price on your safety and that of your passengers?

On Board Diagnostics For Denver Motorists
Posted January 17, 2012 11:03 AM
Some Denver motorists are confused by Downing Street Garage charges for diagnostic services for a vehicle repair. Many services at Downing Street Garage and other Denver automotive repair shops include diagnostic fees.
When you take your laptop into a Denver computer repair shop for a problem you’ll likely have to leave a deposit for diagnostics. When we visit our Cherry Creek doctor for a medical problem, we’re paying him to diagnose our ailment and of course for the tests that go along with it.
So receiving a diagnostic charge at Downing Street Garage for a tricky automotive problem shouldn’t be a surprise. In the Denver 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 Colorado 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, Downing Street Garage diagnosis may be much more involved.
Much of the Denver 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 Cherry Creek, Washington Park, and Capital Hill drivers that the trouble code tells the Downing Street Garage 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 Downing Street Garage 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 Downing Street Garage Denver customers. The Downing Street Garage technician makes a list of the most likely causes and begins tracking down the source of the problem.
Denver 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 Downing Street Garage wants to figure out what’s wrong with your sedan and get you back on the road as quickly as possible.

Power Steering: Keep Headed in the Right Direction, Denver
Posted January 12, 2012 11:46 AM
Power steering is standard on nearly every car and truck in Denver, Colorado these days. Now there are some exotic, new types of power steering systems, but for the most part, the heart of the system is a pump that’s driven by a belt powered by the engine.
Contact us at Downing Street Garage for questions about your power steering.
The pump generates boost that assists you as you steer your sedan around Denver, Colorado. Power steering systems use hoses to move pressurized fluid back and forth. These hoses can develop leaks so it’s a good idea to inspect them at every oil change.
A check of the power steering fluid level is on the list for every full service oil change because low fluid can damage the power steering pump. And the fluid needs to be compatible with the hoses and seals, so you need to use the correct type –just ask your service consultant at Downing Street Garage.
In addition to providing boost, the fluid cleans, cools and lubricates the power steering system. The lubricants and detergents are depleted over time so you need to replace your old fluid with clean, fresh fluid periodically.
Excess moisture can collect in the power steering fluid as well. That can lead to rust and corrosion as well as reduce the effectiveness of the fluid. Many manufacturers specify power steering service intervals in the owner’s manual. Unfortunately, this important service is sometimes left off the maintenance schedule. When in doubt, every two years is a good fallback.
Your auto service center in Denver, Colorado will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.
Now, if you are experiencing high steering effort, erratic power assist, loud whining coming from the pump you may have a power steering problem. Another sign is that you have to frequently top off the fluid.
Holding the steering wheel to the far right or left for more than a few seconds at a time can wear your pump out real fast. AutoNetTV wants you to be sure to service your power steering system regularly to keep you headed in the right direction.

What To Do In Case Of An Accident in Denver
Posted January 3, 2012 2:27 PM
Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in Denver, even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.
Let’s review what you should do in case of an accident:
When an accident occurs, you should always stop. Leaving the scene of an accident in Denver is considered a crime - even if it’s not your fault. And hit and run penalties are fairly severe, possibly resulting in steep fines, loss of your Colorado driver’s license or even jail time.
Your jurisdiction may require that you try to help someone who is injured by calling for help or performing first aid if you are able. Warn other Washington Park and Capital Hill motorists by putting out flares, using your flashers or lifting your hood. Call Denver emergency services as soon as possible. Tell the operator if medical or fire help is needed.
Always file a Denver police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you’ll not have an objective report to help defend yourself. Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of the law, the other guy is responsible.
Truthfully give the officer the facts: such as "I was going thirty miles an hour" not "I wasn’t speeding". Remember, anything you say to the officer or anyone else can be used against you.
Also get the officer’s name and ID number and ask where you can get a copy of the accident report.
Get the facts on the driver and owner of the other vehicle:
- Name
- Address
- Phone number
- Date of birth
- Driver’s license number and expiration
- Insurance information
Also take down a description of the other Denver vehicle, license plate and vehicle identification number. Most Colorado auto insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.
Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary. Always call your insurance agent or your insurance company. Call or see a physician if you think you may have been injured. For vehicle repairs, call Downing Street Garage at 303.777.0142
Contact Downing Street Garage to learn more about what do do in case of an auto accident.

Downing Street Garage and AutoNetTV hope that you never have to use this information and wish you happy Denver travels.

Higher Mileage Service Intervals For Denver
Posted December 29, 2011 10:59 AM
The government mandates a lot of equipment on cars for the Denver Colorado area: emission devices and control computers; safety equipment like airbags; and crash worthiness requirements. All of this is great for the motoring public in Denver Colorado, but it does add quite a bit to the price of a new car.
Because new cars are more expensive, people are driving their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge - but they need a little help to keep on going.
Some owner's manuals don't specify service requirements at higher mileage. That doesn't mean it doesn't have to be done. In fact, it's more important than ever to stay on top of routine maintenance for cars with more than 120,000 miles/190,000 kilometers. Just extend regular service intervals out: for instance a service that's recommended every 24,000 miles/38,000 kilometers should be performed at 24,000 mi/38,000 km; 48,000 mi/77,000 km; 72,000mi/116,000 km, 96,000 mi/154,000 km; and on and on.
Because of the additional stress older engines experience, the severe service maintenance schedule may be more appropriate than the regular schedule. Watch for leaks - seals and gaskets dry out over time and do not hold the fluids as well as they used to. It is also time to make sure you have a good technician. There are some services and replacements that are scheduled after you put some clicks on the odometer, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course.
Check for unusual sounds, smells or the way your car feels. These could be hints that trouble is brewing. Better to catch it early before it turns into a costly repair. Regular wash and wax will help maintain your car's appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a higher mileage.
High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older engines are dirtier inside - and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection. Come into Downing Street Garage for a checkup.
Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high kilometer vehicles. So once you hit around 50,000 mi/80,000 km, consider stepping up to high mileage formulations. The fluids cost a bit more than standard fluids because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road.
It does cost more to properly maintain a higher mileage vehicle - but it's much cheaper than a new car payment!

Serpentine Belt Replacement Near The Denver Area
Posted December 23, 2011 1:13 PM
Don't you hate it when you hear that squeal from under the hood when you're driving aroun Denver? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator-which charges the battery, the water pump-which cools the engine, the air conditioning and the power steering pump. All pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components.

Serpentine belts are especially tough. They can last for years and go for tens of thousands of miles. But, with time they wear out. If your belt breaks while you are driving, everything will come to a halt within minutes. You have to stop the car or it will overheat, potentially causing major engine damage. And it probably won't be at a convenient time or place. You might even need to get your car towed to a service center. That is why manufacturers recommend a belt replacement on schedule. You really should get it done on schedule because a belt failure will definitely take you off the road.
If you hear a squeal when accelerating or a slow, slapping sound at idle, you should have your serpentine belt looked at. Your Denver area service technician at Downing Street Garage will visually inspect your belt to see if it needs to be changed sooner than scheduled. If the belt has more than three or four cracks an inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.
Serpentine belt replacement is relatively inexpensive, especially compared with the cost and inconvenience of being stranded or getting a disabled vehicle back to Downing Street Garage for repairs.
An ounce of prevention is worth a pound of cure.

Risk of Extended Oil Change Intervals
Posted December 13, 2011 9:59 AM
Nothing in your engine workers harder than your oil. With hundreds of moving parts, and thousands of explosions every minute, it's no wonder that engine oil needs to be changed frequently!
You've probably heard the old rule of thumb: Change your oil every 3,000 miles/ 5,000 kilometers or 3 months, whichever comes first. But some car manufacturers have introduced extended oil change intervals. They figure that a modern vehicle driven under the right conditions can go for 5,000 miles/8000 kilometers or more between an oil change.
The key phrase here is "under the right conditions". If you look at your owner's manual, you'll see two different maintenance schedules: one for "normal" driving conditions and one for "Severe Service". Severe service driving conditions include stop and go, short trips, towing, hauling, hot, cold, and dusty driving. That's why at AutoNetTV we often refer you to the severe service schedule in your owners' manual, because, for most of us Colorado car owners, that's the way we use our vehicles in everyday life.
Recently, four of the largest auto manufacturers in the world have extended engine warranty coverage for engine damage caused by oil sludge resulting from longer oil change intervals. They found that real-world conditions require more frequent oil changes than the 7,500mi/12,000 km interval they were recommending. They subsequently recommended more frequent oil change intervals and proof of timely oil changes in order to qualify for the extended warranty.
Oil sludge is the culprit. Sludge is oil that has turned to a thick, jelly-like consistency. Sludge can block passages in the engine, preventing oil from lubricating vital engine parts. Parts wear more quickly and may fail prematurely.
Sludge is caused by several factors. The first one is simply - time. The engine oil is contaminated by exhaust gas that eventually leads to sludge. That is where the recommendation to change your oil at least every three months comes from. Sludge can also come from oil that gets contaminated by water from normal condensation. A few minutes of driving at Colorado freeway speeds allows the oil to heat up enough for the water to evaporate. The problem is we often run errands or take other short trips that don't allow the engine to warm up enough for the water to evaporate. This is especially true in winter. Sludge also forms when the engine gets too hot, causing the oil to breakdown. Stop and go summer driving, towing and hauling are all prime conditions for creating harmful sludge. And every engine has hot spots that create sludge.
Given all of these factors, estimating when to change your oil is pretty complicated. A couple of manufacturers have computer programs built into their vehicles that record the number of cold starts, how many times the cylinders fire, engine temperature and other factors. From that, the computer estimates when you should change your oil and flashes a warning. But what if you do not have a vehicle with this feature? How do you know when to change your oil? We're not sure you really can. Which is why it is better to be safe than sorry. 3,000 mi/5,000 km or three months - whichever comes first - talk with a service advisor at Downing Street Garage in Denver and see if that's a good recommendation for the way you drive.

Alternative Fuel Vehicles In Denver Colorado
Posted December 7, 2011 2:21 PM
Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our Denver environment, automakers will have a number of alternatives for us very soon.
For instance, Flex Fuel vehicles are already available in the Denver area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn.
The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline.
You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.
Diesel engines have been around the Denver area for a long, long time. Modern diesels are very refined and fuel efficient. Diesel fuel can be made from renewable sources like vegetable oil, too. Diesel fuel from algae and sunlight is reported to be pretty close to being commercially viable.
There are also a number of natural gas vehicles on our Denver roads. Gasoline engines are adapted to run on compressed natural gas. It's less expensive than gasoline and burns very cleanly. You can even refill it with a special pump from your gas line at home.
Natural gas engines don't make as much power and don't get as good of mileage, but they cost less per mile to run. The big inconvenience is that the tank that holds the compressed natural gas takes up a lot of room; even your whole trunk! And there may not be places to refuel on a road trip from Denver.
Plug-in electric vehicles are now available in our Denver area. Battery technology is the limiting factor right now. Electric cars have a limited range and are really best for use close to home. As battery technology advances, electric cars will perform closer and closer to conventional power plants.
That brings us to hybrids. There are a bunch of hybrids on our Denver roads, with more to come. Hybrid technology combines internal combustion engines with electric motors.
A mild hybrid has a regular gas or diesel engine that's assisted by the electric motor. The electric motor can propel the vehicle by itself up to a certain speed under gentle acceleration. There are mild hybrids in full-sized pickups and SUVs. They deliver city fuel economy similar to their highway ratings.
A full hybrid will rely primarily on the electric motor for power. It'll have a small gas or diesel engine that generates electricity for the batteries.
Another breakthrough technology is hydrogen fuel cells. Fuel cell vehicles use hydrogen to generate electricity. Several global car makers have prototypes on the road. The appeal is that the only thing that comes out of the tail pipe is water vapor. It'll take some time to build a national infrastructure of hydrogen fueling stations before there's widespread use.
A quick word about safety around hybrid and electric vehicles. Unlike the battery in your current family car, these carry enough voltage to kill you. Never mess around under the hood or with the batteries or electrical wiring. Your Denver service technician at Downing Street Garage is trained to safely disable the flow of electricity before performing maintenance or repairs on the vehicle.
Hybrids are really not do-it-yourself vehicles unless you're specifically trained on hybrid systems.

Fuel Saving Tip: Denver Tune Up
Posted November 29, 2011 12:42 PM
Have you ever gone to Denver to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That's why they tune up together.
Now this is no surprise; I'm going to relate the orchestra to your car. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.
We call this, (ta-da) a tune-up. When an orchestra's out of tune you get a bad concert. When your vehicle's out of tune you get bad performance and bad fuel economy.
So check your owner's manual for recommended tune-up intervals. Or ask your Denver service advisor at Downing Street Garage what he thinks.
...Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.
