What Is a Differential and Do You Have One?

With front-wheel drive being so common these days in Quincy, IL, the differential is just taken care of during a transmission service, so most Quincy drivers don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of Quincy customers' minds. It's not uncommon for drivers to not know they have a differential let alone know that it needs service.

Call Spring Street Automotive Inc in Quincy at 217-228-9141 for information about differential service, or stop by our Quincy, IL, auto center at 1701 Spring Street, 62301.

To better understand what a differential does, think about our local Quincy high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars in the Quincy, IL area weigh between 3,000 and 6,000 pounds (1,400 and 2,800 kg) – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool.

The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So vehicle manufacturers recommend intervals for replacing your differential fluid.

The professionals at Spring Street Automotive Inc will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. Then they’ll replace the fluid and install the additives if necessary.

Your Spring Street Automotive Inc service advisor can look up the vehicle manufacture's recommended service interval or you can check your owner's manual. Give us a call at 217-228-9141 for more information about your differential service.

Timing Belt Service to Save Big Bucks in Quincy

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine has to do with the combustion cycle.

Your vehicle engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves that open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call Spring Street Automotive Inc at 217-228-9141 for answers about your timing belt, or drop by our Quincy, IL, service center on 1701 Spring Street.

It's critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It's vital and precision work. Timing belts are made of very tough, flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bent or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It's a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it's at 60,000 miles/97,000 km. For others it's at 90,000 miles/145,000 km or more. If you're approaching 60,000 miles/97,000 km or have passed it, make sure you check your owner's manual or with your Quincy auto service advisor at Spring Street Automotive Inc for when the timing belt should be replaced. Don't let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Spring Street Automotive Inc for an inspection right away if you have a coolant leak.

Most people in the Quincy area with this engine design end up with a new timing belt when they replace the water pump. And when you're having your timing belt replaced on schedule, check with your Spring Street Automotive Inc auto service advisor to see if it makes sense to install a new water pump, even if it isn't currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don't need to be replaced like belts.

We've already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Spring Street Automotive Inc in Quincy, IL, so you can begin to prepare for the expense.

We at Spring Street Automotive Inc, your Quincy service center, can be a valuable partner. Please take advantage of our knowledge and experience.

How Far We've Come (Newer Vehicle Technology)

Automotive design has come a long way since the days of the Model T, especially when it comes to safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years.

Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops. 

Automatic emergency braking.  We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If you don't heed the warning, they'll put on the brakes for you. 

Blind spot warning.  We all worry about hitting a car approaching from behind and on either side if we are changing lanes.  Rearview mirrors cover some blind spots but they're not foolproof.  Enter the blind spot warning system; it warns you with a noise or a light if a vehicle is in a spot you might not be able to see.

Lane departure warning.  We all try to stay in our lane, but sometimes our attention wanders.  If you start to drift out of your lane, new warning systems using cameras and other sophisticated sensors will tell you to get back in your lane.  Some send an audible warning, others use a vibration or warning light. Some will even steer your vehicle back into the lane. 

Rearview camera.  There was a time when trucks and SUVs were involved in horrible accidents because the drivers couldn't see what was behind them as they backed up.  Children and pets were among the tragic victims.  Now, inexpensive rearview cameras are required in the U.S. and Canada, saving lives and providing much more peace of mind for drivers of vehicles with rear visibility issues. 

It's important to make sure this safety technology is working correctly for these systems to be effective.  Your service facility can check and maintain these systems as the manufacturer recommends.

Fresh Air Inside Your Car in Quincy

Air quality has certainly become a hot issue in our modern world. We install air filters on our ventilation systems and in our vacuum cleaners. There's a filter that cleans the air going into our vehicle's engine — so why not one for the air in the passenger compartment?

Foreign and domestic vehicle manufacturers haven't been ignoring the issue. Cabin air filters are becoming a standard feature on newer vehicles. These filters can clean particles out of the air down to three microns, which accounts for pollen, dust and most pollutants. Quincy residents who suffer from allergies or have a respiratory disorder should be a lot more comfortable. And even if you don't have a medical need for the filter, the cleaner air in your car just might help you breathe better, figuratively as well as literally.

Cabin air filters are still fairly new in the Quincy area, so you'll have to check your vehicle owner's manual to see if you have one. If you do, your routine car care will have to include changing the filter as part of your preventive maintenance. The owner's manual will give recommendations on how often the filter has to be changed, but if the air where you live in IL is particularly dirty or if you're prone to hay fever, you may want to change it more often.

Your friendly service advisor at Spring Street Automotive Inc can also offer suggestions on how often to change your cabin air filter in your Quincy area. They're the ones who actually see the dirty filters, after all.

There is no standardized location for cabin air filters. Quincy residents can usually find them in the vehicle engine compartment or under the dashboard, but they might be somewhere else. So the ease of changing the filter will depend on its location. Some are readily accessible, but others make you wonder how they got installed in the first place. Bring your car into Spring Street Automotive Inc and we will locate your cabin air filter for you.

However, if you have a newer vehicle, it's good auto advice to find out if it has a cabin air filter. If it does, you should change the filter regularly. A sure sign that a filter needs to be changed is that the interior of your vehicle will start to smell bad. That smell is exactly how some Quincy drivers discovered that they had cabin air filters in the first place!

Cabin air filters are just one more way we have to stay safe, stay healthy and stay on the road in IL.
