Exhaust Service at L and M Motors Inc: Passing the Smell Test
Posted November 25, 2014 12:00 PM
The exhaust system on a vehicle is more complex than most Anchorage residents realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All AK 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 L and M Motors Inc in Anchorage.
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 L and M Motors Inc 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 Anchorage 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 Anchorage 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 L and M Motors Inc in Anchorage.
Maintaining your emissions and exhaust system is not just good auto advice: it's good health advice for all Anchorage residents and their families.

Blind Spot Safety for Anchorage Driving
Posted November 19, 2014 12:00 PM
Blind spots may be a good thing when it comes to a spouse's annoying habits, but when driving an automobile in Anchorage, they are definitely to be avoided. So, while it's not good marital advice, it's good auto advice to minimize your own blind spots and stay out of other Anchorage drivers' blind spots, especially when it comes to large, heavy vehicles like trucks and buses.
First, minimize your own blind spots. Do this before you pull out of the driveway or parking space. Adjust your rearview mirror so that you see as much of the area behind you as possible. And, no, this doesn't include the passengers in the back seat. The rearview mirror isn't designed to be a baby monitor.
Next, lean to the side until your head almost touches the driver's side window. Now adjust the driver's side mirror so that it just catches the side of the vehicle. Then, lean to the middle of the car and adjust the passenger's side mirror in the same way. These adjustments will ensure you the widest possible view behind your vehicle.
Of course, you can't eliminate blind spots entirely. There is always an area behind any vehicle where the driver just can't see what's there. The bigger the vehicle, the bigger the blind spot. Toddlers are just the right size to hide in a pickup's or SUV's blind spot. The blind spot on an RV or tractor-trailer can actually hide your crossover! You should always check behind any vehicle before getting in and backing up. And if you sit in the vehicle for a few minutes before backing up, it is best to get out and check again, especially if you are pulling out of a neighborhood driveway in Anchorage. No precaution is too extreme if it saves the life of a child.
Trucks may cause about 60% of the accidents involving a truck and a car, but 78% of fatalities in such accidents are with the smaller vehicle. The number of fatalities in AK, as well as the number of crashes, could be cut significantly if Anchorage drivers learned to properly share AK roads with trucks.
While learning to share AK roads and freeways with trucks and other large vehicles may not seem like preventive auto maintenance, it does, in fact, go hand-in-hand with good car care. Keeping your vehicle out of the body shop can save you big bucks and prevent the stress of a major accident, along with the injuries that could come with it.
The team at L and M Motors Inc in Anchorage urges you to stay safe, and stay on the road!

Go Big or Go Home: Upsize Your Wheels at L and M Motors Inc
Posted November 12, 2014 12:00 PM
A lot of us Anchorage drivers like our vehicles to reflect our personalities. We're picky about color and body style. We'll customize anything from floor mats to window tints to license plates. One popular way for AK motorists to customize a vehicle is to get new wheels.
Wheels come in thousands of designs. Custom wheels can add personality, style or sass to a vehicle. Many of these customizations involve getting a bigger wheel.
Fifteen or 16-inch wheels used to be the factory standard, but today, because a lot of Anchorage drivers like the look of larger wheels, many vehicles are available with 17 or 18-inch wheels. Optional wheel packages of 20 inches or more are also available in Anchorage.
If you want to upsize the wheels on your current vehicle, however, you should know it's not a do-it-yourself project. There are factors involved in ensuring your wheel change doesn't jeopardize the safety of your vehicle.
First of all, you need to understand rolling diameter. The rolling diameter is the overall height of a tire. If you increase the rolling diameter of your tires when you upsize your wheels, you may have to modify your suspension to make sure the larger tires fit in the space and don't rub in turns or over bumps. If that's more work than you're willing to do or pay for, then you need to maintain rolling diameter when you change your wheels.
It's not as hard as it sounds. Imagine a doughnut. That doughnut represents rolling diameter, so you can't make the doughnut bigger. However, you can increase the size of the doughnut hole. That gives you a bigger wheel. Tires with reduced sidewall on larger wheels will preserve your rolling diameter.
Rolling diameter is important because your wheels and tires still need to fit inside the wheel well. Also, your speedometer, odometer and anti-lock brakes are all programmed to work with a specific rolling diameter. You'll throw off the readings on your speedometer and odometer if you change your rolling diameter. And for your anti-lock brakes to work properly, your rolling diameter has to be within 3% of factory recommendations. While some Anchorage drivers who upsize may not be concerned about meter readings, throwing off the brake system is a serious safety hazard.
Further, many vehicles in Anchorage are now equipped with electronically controlled suspensions. Changing the rolling diameter will negatively affect this system as well, which can lead to a less smooth ride and lower handling performance as well as safety concerns.
Your friendly and knowledgeable L and M Motors Inc tire professional may be able to reprogram your vehicle's computer to adjust for a larger (or smaller) rolling diameter.
So to maintain rolling diameter, you'll need tires with a shorter sidewall. These tires will be designed to give the sidewalls the strength they need to maintain ride quality. Consider that doughnut again. As the wheel (the doughnut hole) gets bigger, the sidewall of the tire (the width of remaining doughnut) gets shorter. That means the tire holds less air. The sidewalls have to be made stiffer to compensate for the decreased air capacity.
To improve their strength, the shorter tires will also be slightly wider than your previous tires. But this means you'll have a larger contact patch, or, in other words, a larger area of tire making contact with the road. This can actually increase your handling performance and decrease braking distances. Many AK auto buffs customize their wheels just for this reason—they want the improved performance rather than looks or style. If you drive a truck or an SUV around Anchorage, you might be interested in the extra control an upsized wheel can provide.
Now, that larger contact patch still has to fit inside your wheel well without rubbing when cornering or when bouncing over bumps or potholes on Anchorage roads. This is termed fitment, and you may need a few adjustments so your new wheels will fit properly. You may need spacers so that your brakes will fit inside the new wheels, as well.
L and M Motors Inc tire professionals are experts at mounting, adjusting and customizing wheels. They can give you a lot of good auto advice about wheels and tires and how they affect driving performance and car care. They can help you select wheels and tires that will suit your driving needs and habits.
For example, if you drive off-road around Anchorage, you should consider a higher profile tire. This type of tire will protect your rims from damage while you're bouncing over rocks. Or, if you tow a trailer or haul heavy loads around AK, you'll want a tire with a load rating equal to your demands. Your friendly and knowledgeable L and M Motors Inc tire professional can help you with these types of concerns.
Once you've got your new wheels, have your service advisor at L and M Motors Inc see if you need an alignment. You don't want those new wheels and your higher performance compromised by poor alignment. Get the most out of your investment by getting the work done right at L and M Motors Inc in Anchorage.
Last but not least, remember tire pressure. With larger wheels, your new tires will hold less air and they'll need slightly higher pressure. You'll need to stay on top of preventive maintenance and keep them properly inflated. Be sure to check their pressure at least once a week. If you don't keep your tires at their correct pressure, they will wear out really fast. It will also affect your braking and handling performance.
So smile and show off your vehicle around AK. Make it all yours. Bumper stickers, vanity license plates, custom wheels — strut your stuff!
