Under Pressure in Lansing: TPMS

Have you noticed an increase in price when you get a flat tire fixed in Lansing, or have your tires rotated? It might be the result of your TPMS, or Tire Pressure Monitoring System.

The federal government began requiring a TPMS system on 2008 model year passenger vehicles and light trucks. Some 2006 and 2007 models may have them as well. The system has a warning light that is mounted on the dashboard that will go on if one of the tires becomes severely underinflated.

Why the new requirement? Because underinflated tires are the number one cause of tire failure. Tire blowouts cause crashes and sometimes fatal accidents. Underinflated tires also need longer stopping distance and can skid, both of which also present dangers on Michigan roads. Many flat tires can also be prevented by proper tire inflation, and though this may seem an economic consideration, Lansing drivers who have changed a flat on the side of the road recognize that this has serious safety concerns as well.

Advances in tire technology, specifically the development of radial tires, has made it harder for Lansing drivers to recognize when a tire is underinflated. At a recommended pressure of 35 psi, a tire is seriously underinflated at 26 psi. But the tire doesn't look low on air until it reaches 20 psi. This raises concerns about vehicle owners being able to tell when their vehicles are a safety hazard on the road. Hence, the TPMS.

So, like seatbelts, the TPMS system is expected to save a lot of lives. The technology has been in use in race cars for years, and now it's being mandated for all passenger cars, SUV's, minivans and pick-ups. Besides warning drivers in the Lansing area when their tires need air, the system is required to indicate when it is malfunctioning.

This increased safety won't come without increased costs. Estimates regarding the cost of maintaining the TPMS on your vehicle run from $27 to $100. Also, there will be an added cost for tire repair. Lansing service centers have had to purchase new scanning equipment to work with TPMS sensors and other equipment to repair tires and wheels equipped with TPMS. The pros at AutoSurgeonInc have to be trained to use the new equipment. These costs will have to be passed on to Lansing drivers.

Further, whenever a tire is changed, AutoSurgeonInc will have to deal with the TPMS. Sensors will have to be removed, then re-installed and re-activated. Sometimes the act of changing a tire will damage a sensor, and it will need to be replaced. These extra services will come at an added charge to Lansing drivers.

Tire rotations will require that the TPMS be re-programmed. And whenever a vehicle's battery is disconnected, the TPMS will require re-programming as well.

The TPMS itself will require attention – it contains batteries and sensors that will wear out and need to be replaced.

So, if you've noticed an increase in the cost for vehicle care at your Lansing tire center, it may not be the economy. It could be the cost of the TPMS in newer vehicles. Before you dash off an angry letter to Congress, however, stop and consider what you're paying for. If predictions are correct, the TPMS will save lives, and that will be a benefit to all of us.

Of course, no warning system will save lives in Lansing if drivers don't pay attention to it. And remember that the warning doesn't come on until the tire is severely under inflated; you still should check your tire pressure at least once a month. You can prevent accidents and potentially save lives without a warning system by keeping their tires properly inflated.

Safe driving!

Fuel Injection Keeps Getting Better for Lansing Motorists

Lansing residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.

Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.

Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy for Lansing drivers as well as delivering less power to the engine.

Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice for Lansing residents. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance at AutoSurgeonInc in Lansing. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.

Getting the Right Tires and Wheels in Lansing

A lot of people get custom wheels in Lansing. When you do this yourself (over the internet . . .) you could run into trouble if you're not careful. Sometimes, once they're mounted, they just don't fit right. The tires rub in turns or on bumps. You don't want that.

Consulting your AutoSurgeonInc tire professional can ensure you get the right fit. First he'll ask you a series of questions about your Lansing driving needs and what you want in your new wheels. Now, not every wheel can go on every car. Care must be taken so that tires and wheels are not too large or that the wheel is centered too far towards the outside or the inside so the tires rub.

If you don't want to make any modifications to your vehicle, you would need to focus on the wheels that would fit. With trucks, some people in Lansing like much bigger tires so they need a suspension lift.

Also, most Lansing drivers don't realize that you need to keep the rolling diameter of your new tires – the overall height of the tire – very close to what came from the factory in order for your vehicle's anti-lock brakes and stability control systems to work properly.

The computers that control these systems are calibrated to a certain size tire. When you go bigger or smaller, the computer doesn't know what changes you made so it can't tell how fast you're going. This, of course, means it sends commands to the brakes and traction control that are based on the wrong speed. If you go with a different rolling diameter, your vehicle engine control computer can be reprogrammed for the new tire size.

Either way, there are hundreds of wheel and tire choices to choose from in Michigan. You can pick the style of wheel you want and then talk with your friendly and knowledgeable AutoSurgeonInc tire professional about how big the wheel should be – and how to select the right tire for your vehicle. Your AutoSurgeonInc service advisor will help you find the best tire to meet your style, performance, ride and handling needs in Lansing.

Exhaust Service at AutoSurgeonInc: Passing the Smell Test

The exhaust system on a vehicle is more complex than most Lansing residents realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All Michigan folks know a properly functioning exhaust system is good for the environment, but sometimes we forget that a damaged exhaust system can be deadly. That's why preventive maintenance on your exhaust system is so important. We can help you with that at AutoSurgeonInc in Lansing.

The exhaust manifold is the first component in your exhaust system. The manifold is attached to the engine. It collects the gases that are produced by the engine and directs them into the exhaust pipes. At this point, these gases are both hot and chemically dangerous.

One of the gases produced in your engine is carbon monoxide. This gas is colorless and odorless. Breathing it can cause headaches, dizziness, nausea and drowsiness. Continue breathing it and you will die.

To keep this gas and others from entering your vehicle passenger compartment, the connections from the manifold to the engine and from the manifold to the exhaust pipes are sealed with gaskets. These connections should be routinely inspected at AutoSurgeonInc for cracks and to check if they have come loose.

The exhaust pipes can also get damaged, allowing dangerous gases to leak into your passenger compartment. These pipes can rust or be dented or broken by rocks and other roadway debris, so they need to be inspected regularly.

The catalytic converter is the next component in your vehicle exhaust system. You can breathe a sigh of relief now, because this is where the dangerous engine gases are converted into carbon dioxide and water, greatly reducing the amount of harmful emissions in your exhaust. You'll also be happy to know that your catalytic converter doesn't require maintenance. However, it will wear out. If you fail an emissions inspection because of a faulty catalytic converter, you need to replace it.

The muffler's job is far less critical, but far more noticeable, than the catalytic converter's. It dampens or absorbs the noise from the engine. Most Lansing residents don't realize that we can actually customize the noise our car makes with a custom muffler. You can upgrade to a muffler that will make your car sleuth-quiet, or you can advertise your presence in Lansing with a sassy rumble.

Mufflers can also rust or be damaged by road debris. But just because their main function is to dampen out engine noise doesn't mean they can be ignored. If your muffler is leaking, you need to get it replaced quickly. Exhaust fumes need to exit through your tailpipe, not your muffler.

The exhaust pipe contains at least one oxygen sensor. The sensor monitors the oxygen content of the exhaust, which allows it to adjust the fuel-to-air ratio in the engine. This keeps your vehicle engine running smoothly and maintains good fuel economy. So, besides keeping you and the environment healthy, a well-maintained exhaust system also keeps your vehicle healthy. The tailpipe itself can rust or get damaged by road debris, so it needs a quick inspection once in a while, too.

The whole exhaust system is mounted on the vehicle with clamps and hangers. These clamps and hangers can come loose, rust or get dinged up by road debris. Remember that the gases in your exhaust system are hot, so the exhaust system itself gets hot. The clamps and hangers keep the exhaust system attached to the vehicle, but they also prevent the heated components from touching things they shouldn't. If you don't inspect and replace broken, loose or damaged clamps, you may end up with melted wires, hoses or lines. And that can spell some expensive repairs.

You should schedule an exhaust system inspection as recommended in your vehicle owner's manual. Because this system is critical to your health and the health of your car, and because of its sophistication and complexity, you need to have the work done at a qualified service center such as AutoSurgeonInc in Lansing.

Maintaining your emissions and exhaust system is not just good auto advice: it's good health advice for all Lansing residents and their families.
