Bad Vibes

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something.

There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. 

So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall. 

That's the same thing that's happening with an out-of-balance tire/wheel combination.  A technician has special equipment to figure out where to put small weights on the wheel to get things back in balance again.  But it could be that you hit a pothole some time ago and bent the rim.  Or your tire isn't as round and even as it once was.  That could be due to age, damage or wear and tear. The technician will know and offer you options.

Another possibility for that vibrating wheel is a faulty brake, such as warped rotors or a sticky caliper.  All of these issues can be evaluated as part of regular, routine maintenance with us.  There are many things that cause vibrations in your wheels.  But you don't want any bad vibes when it comes to your vehicle. 

Fuel Filter Service in Memphis, TN

There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.

Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember because it is a long list, but your service center at Madison Automotive can help you know what's scheduled to be taken care of.

Some of us in Memphis, TN, really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention and addressing small problems before they get big. Let's take the fuel filter for example.

You may not know this but the median age for private vehicles on our Memphis, TN, roads is over nine years. When vehicles get older, five years or so, they've accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation is the lowly fuel filter: a very inexpensive part that doesn't cost too much to replace. And your vehicle will just run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the Memphis, TN, freeway or when you accelerate. Enough fuel can't get through to meet the demands of higher speed. If it gets bad enough, your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We've already talked about how expensive that can be.

The fuel filter is even very important for newer vehicles. The fuel is still dirty even if there isn't rust in the tank. It's just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner's manual. Your Memphis, TN, service advisor at Madison Automotive can tell you as well. It's usually around 30,000 miles (50,000 kilometers) or so. Ask if it's time for a full fuel system cleaning as well. They often go hand in hand.

It's good to know that your Memphis, TN, service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of Madison Automotive as your ally - and maybe even your memory.

TN: What Is the Risk of High Oil Change Intervals?

TN residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.

Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.

So what is a good time interval for oil changes? How do TN residents know when to change it? And why do we change it in the first place?

Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for TN residents. What you really want to avoid is called oil sludge.

Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.

Sludge forms rapidly in an engine that is driven under what are termed “severe conditions.” A vehicle's owner's manual includes recommendations for oil change intervals under both normal and severe conditions. Severe conditions include towing a trailer, driving in polluted or dusty conditions, hauling heavy loads or using a car top carrier. Also, extremes in climate such as very hot or very cold temperatures constitute severe conditions for vehicles.

Some people may be tempted to overlook the severe conditions preventive maintenance schedule in their 's owner's manual because of the word “severe.” But consider this: the most common form of severe conditions is stop-and-go driving, rush hour commuting or only driving your vehicle on short trips around the area.

When a vehicle only makes trips under four miles/six kilometers, or under 10 miles/16 kilometers in freezing conditions, the engine doesn't get warm enough for condensation in the oil to evaporate. The result? You get oil sludge build-up. If your driving patterns are the same as any of the conditions that count as severe, you should be changing your oil more frequently under the severe conditions schedule. 

The team at Madison Automotive in Memphis can help you understand what type of oil to use in your vehicle and how it can affect your oil change schedule. Some vehicles are filled with synthetic or synthetic-blend oil at the factory. The owner's manual will recommend that this oil continue to be used in the vehicle, and oil change intervals will be based on this type of oil.

Also, if your vehicle uses conventional oil, but you have some of those severe driving habits we talked about, you can switch to a premium-grade oil to give your vehicle extra protection. The answer to why we change our oil is fairly simple: to protect our engines and make our vehicles last longer and run better. But the answer to how often to change our oil is more complex: it depends on our vehicle, our driving habits, where we live and what kind of oil we use.

When it comes to oil changes, a little information can go a long way to helping people save money and extend the life of their vehicles. Stay safe, and stay on the road.

Water Pump

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system:

• the radiator
• the radiator cap
• the hoses
• the thermostat
• the water pump

The water pump's like the heart of your cooling system, circulating the fluid throughout your vehicle. It's a small pump that's driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine's running. Water pump failure is pretty routine. We see it often at Madison Automotive. Some start failing at around 40,000 miles/64,000 km, but most fail by 100,000 miles/160,000 km. Consult your owner's manual or friendly and knowledgeable service advisor at Madison Automotive to see what's recommended.

Since a water pump either works or it doesn't, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It's possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can Memphis drivers tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump, it's got a problem. If you can see coolant in that area, you've got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can't see the water pump. Look for coolant on the driveway. If you see some, have Madison Automotive check it out.

Most timing belts need to be changed at 60,000 miles/97,000 km – some longer. It's a good idea to change your water pump at the same time if it's one of those that's driven off the timing belt. To start with, 90% of the work's already done with the timing belt change. And if you don't and develop a leak later, you'll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

Madison Automotive can replace a failed water pump with a brand spankin' new one or with a rebuilt pump. Rebuilt will save you some money, but ask your service advisor at Madison Automotive what he thinks. Don't feel too bad if your water pump gives out. They will all wear out eventually. We can get you back on the road and on with your life.
