Good Timing: Proper Timing Belt Replacement Saves Money for Rockford Drivers

Knowing how their engine works can help Rockford drivers make informed decisions about auto care and prevent repairs to their vehicles. This is especially true when it comes to timing belts.

An engine's power is generated in the cylinders. Inside the cylinder is a piston that moves up and down while the engine is running. Power is generated in a cycle that includes four strokes of the piston. First, the piston drops and a valve at the top of the cylinder opens to let in fuel and air. The piston then rises, which compresses the fuel and air. At this point, the spark plug fires, igniting the fuel and pushing the piston down. This downstroke transfers energy to the engine, which provides the power it needs to run. The piston rises again, and a valve opens to release the exhaust.

All of this movement is orchestrated by a timing belt. The timing belt is so named because it keeps the pistons and valves operating in synch with each other, just as a conductor keeps all of the instruments in an orchestra in time with one another. Thus, the timing belt is critical to the proper operation of your engine.

Not all vehicles in the Rockford area have timing belts. Some have timing chains. A timing chain is more durable and rarely breaks, but timing belts are cheaper, so many use them to save money.

Timing belts wear out and break, so part of preventive maintenance for Rockford drivers is to replace the timing belt on schedule.

The results of failure of a timing belt depend on the type of engine in your vehicle, but they are always inconvenient and can be very costly for Rockford auto owners. If your engine is a non-interference engine and the timing belt breaks, the engine simply stops running. Now that can be an incredibly inconvenient situation depending on where you are driving around Rockford when it breaks, but it won't cause any engine damage. On the other hand, if your vehicle has an interference engine and the timing belt breaks, the valves on your cylinders will actually fall into the path of the pistons. Then things start getting chewed up by the motion of the engine and it will cost thousands of dollars to get everything sorted out again. Compounding the problem is that there aren't any warning signs before a timing belt breaks. A visual inspection of the belt is difficult also. In some vehicles, parts of the belt may be visible, but most vehicles hide the belt under a cover.

The timing belt doesn't even have to break to cause major engine damage. If it slips, even one notch, the result could be engine damage with repair costs in the thousands of dollars.

Our only car care option is to simply replace the timing belt periodically. You can check your owner's manual to find out how often your timing belt should be replaced. Many vehicles need a replacement at 60,000 miles (100,000 kilometers), but the recommended replacement mileage could be as high as 90,000 or 100,000 miles (145,000 to 160,000 kilometers). If your owner's manual recommends replacement at 60,000 miles (100,000 kilometers), however, don't wait until 65,000 miles (105,000 kilometers) to get it done. Remember what you're risking.

Replacing a timing belt is not a cheap part of preventive maintenance for Rockford vehicle owners. The belt is usually difficult to get to and often requires removal of some of the engine accessories. The cost of the replacement, however, is a lot less than what the repairs may cost if the timing belt fails.

When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing Rockford drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in Rockford to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.

If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their suspension system. Struts are a compact combination of springs and shocks. They do the same job but in a single package.

Shocks wear out gradually, so it can be difficult for Rockford drivers to notice when they need to be replaced. There's no definitive point when a vehicle's ride goes from "smooth and controlled" to "a bit imprecise." To check if your shocks or struts are worn, you should first do a visual inspection on them. If they are leaking fluid, they need to be replaced.

There are other less obvious signs that your suspension system needs attention. For example, an uneven, cupping wear on your tires may indicate that your shocks are worn. If your vehicle feels “floaty” when you turn, or, in other words, you don't feel that you have full control of the vehicle, you should check your shocks. Also, if the front end of your vehicle dips noticeably when you stop, it's time for new shocks.

Your owner's manual gives recommendations on how often the shocks should be checked, usually between 15,000 and 30,000 miles (24,000-50,000 km). If one of your shocks does need to be replaced, you should replace all four. This will keep your suspension even and ensure good handling of your vehicle. If you carry heavy loads, tow a trailer or drive on uneven Rockford area terrain, you might also consider upgrading to a heavy-duty shock.

Regular shocks contain hydraulic fluid. The fluid helps them absorb the bumps or “shocks” of the road so the impact doesn't transfer to the vehicle's body. Premium shocks are filled with compressed nitrogen gas, which costs more but does a better job of controlling body motions. Regular shocks can develop air bubbles that reduce their effectiveness; the premium shocks don't have this problem. So if you want higher handling performance, if you drive off-road around Illinois or if you just want added comfort, you should consider upgrading to premium shocks or struts.

Replacing struts can put your vehicle out of alignment, so an alignment check should always follow this type of repair. Talk to your service advisor at TJ's Auto Center Inc. in Rockford for more information.

Time Out: Suspension Problems in Rockford

Your vehicle's suspension system has two jobs: to prevent the passengers from getting tossed around inside the vehicle every time it hits a bump in the road and to keep the tires firmly planted on the road around every corner and over every bump.

To see your suspension system, you'll have to look under your vehicle. Anything that connects the wheels to the vehicle's frame is part of the suspension system. They're heavy-duty parts that work hard while you're driving and take a lot of wear and tear. Because of this, you should have your technician at TJ's Auto Center Inc. look at them once a year as part of your preventive maintenance routine. A good time for it is every time you get your alignment checked.

If your suspension is in trouble, you often feel it in how your vehicle drives. You should get a check of your suspension system: if the vehicle pulls to one side or wanders, if the steering is erratic, if your ride isn't as smooth as it should be, or if your vehicle handles poorly. Uneven tire wear can also indicate worn parts in your suspension system. If your shocks are leaking oil then they definitely need to be replaced. All in all, if you don't feel in control when you're driving, go get your suspension inspected.

Shocks and struts wear out. Wheel bearings may need to be repacked every few years. Some parts of your suspension may need to be lubricated whenever you change your oil. Preventive maintenance is the key to keeping your vehicle under control. Good care can prevent accidents for Rockford drivers.

If you are in an accident, even a minor one, it can damage your suspension system or knock your wheels out of alignment. Even hitting a curb, pothole or large rock can damage your suspension. A wheel balancing or alignment won't correct a suspension problem, and after any suspension work, you may need to get an alignment.

At TJ's Auto Center Inc., we advise Rockford drivers never to procrastinate on getting their suspension system repaired. A damaged suspension system can lead to loss of control of a vehicle in an emergency situation and serious accidents.

Potholes are unsightly nuisances around Rockford, but they're also a major cause of suspension damage for Rockford vehicles. To avoid this, Rockford drivers should always keep their tires properly inflated. This gives the tires maximum resiliency. When you're driving around the Rockford area, avoid potholes if possible. If you can't avoid one, then slow down before driving over it. Slower speeds limit pothole damage. But if you're a little late detecting a pothole, don't brake on top of it. This will throw the vehicle's weight forward and increase the damage.

The suspension system may not be pretty to look at, but it provides you with a safe, comfortable ride — as long as you maintain it properly. You don't have to show it off, but you should be proud of it.

Your Vehicle Is NOT Maintenance Free, Rockford Car Owners

A generation ago, Rockford drivers seemed to be more inclined to keep their vehicle's preventive maintenance on schedule. One reason for this may be that vehicles back then were a lot less reliable than they are today. Taking your vehicle in to your Rockford shop every year or two for repairs seemed to be a good reminder to keep the oil changed.

For example, almost everyone in Rockford used to take their vehicles in for regular tune-ups. Vehicles had mechanical ignition systems, which meant ignition points, spark plugs and coils had to be replaced and the timing adjusted every few years. As long as the vehicle was in for a tune-up at TJ's Auto Center Inc., the vehicle was inspected and you took care of any needed repairs at the same time.

Today's engines have electronic ignition systems and engine control computers. Spark plugs can last for up to 100,000 miles/160,000 km. Vehicle reliability has vastly improved in the last few decades, and surveys report fewer problems with new vehicles than ever before. That also means that our vehicles don't experience a huge performance drop when they're ready for some care. But it doesn't mean that they don't need it.

Modern Rockford drivers need to rely on calendars and mileage intervals to know when to schedule maintenance. Owner's manuals contain recommendations on when different types of maintenance should be performed. Also, TJ's Auto Center Inc. in Rockford can provide advice about auto maintenance schedules. At TJ's Auto Center Inc. in Rockford, we know that benefits of staying on top of preventive maintenance are substantial. First, you'll get better engine performance and fuel economy. Those two things alone return the cost of preventive maintenance: in fuel savings and safety. Also, routine maintenance has been proven to prevent major car repairs later on. Again, the cost savings can be significant. As the old saying goes, “Spend a penny, save a dime.”

Modern vehicle engines may be more durable and reliable than their predecessors, but they're more sophisticated and complex as well. For this reason, preventive maintenance today is even more critical than the old tune-up. Modern engine systems have a lot of parts that have to stay lubricated. These parts can be made of aluminum, plastic or steel. Special additives in lubricants are required to keep each of these materials from breaking down or corroding. Over time, these additives are depleted, even if the vehicle isn't driven. This makes fluid changes a critical part of scheduled maintenance if you want to keep your vehicle on the road.

As an example, coolant fluid in your engine is a sophisticated mix that not only keeps your vehicle engine cool but also protects and maintains its components. However, this fluid gradually gets contaminated and anti-corrosion additives are depleted. It can become corrosive and damage the vehicle's engine parts it was designed to protect. It can eat holes in your radiator and other engine parts. Changing the coolant could have prevented this damage, and it's a whole lot easier and cheaper than replacing a radiator.

Timely oil changes are more critical for Rockford drivers than they used to be. Skipping just one oil change can start the build-up of oil sludge in your engine. Sludge can clog small engine passages, which cuts off the supply of lubricant to engine parts. Just this small bit of sludge can reduce the life expectancy of your engine. If the build-up continues, it could lead to engine failure within two or three years.

One word of warning to anyone in Rockford who purchases used vehicles: take care when buying a leased vehicle. Rockford folks who lease vehicles only intend to drive them for two or three years, generally the years when the vehicle is least likely to experience any problems. One of the reasons people lease vehicles is that they don't want to be bothered with maintenance or vehicle care. Before buying a pre-leased vehicle, be sure to inspect it for signs of damage that result from lack of proper care.

We can all be grateful for the improved reliability of our modern vehicles. With proper maintenance and care, we can expect them to last longer, perform better, get better fuel economy and require fewer repairs than ever before. We just have to be more conscientious about scheduling time for their care.
