Why Won't My Car Start? St Charles IL Auto Repair

Ever been jealous of your local mechanic, family friend, or even that good Samaritan by the side of the road who can start up your temperamental car and diagnose the problem within seconds? Much like a horse or baby whisperer, they clearly have learned a special language. Whether your car is barely starting, making strange noises, or is completely dead, here are a few basic tips to help you know what to look and listen for.

Steering Wheel Lock: First off, are you able to turn your key? In order to frustrate carjackers, your steering wheel locks in place when you remove the key. So if the key is not turning, don’t force it. Rather, try yanking lightly in either direction on the steering wheel to disengage the wheel lock. Do this as you turn the key and you’re on your way.

When Do I Need to Replace My Timing Belt? Rx Automotive 630.443.8500

Why Do I Need to Replace My Timing Belt?

A timing belt, also known as a cambelt, is a very important part of your car or truck’s engine that is responsible for its smooth functionality. The timing belt actually controls the camshafts in the engine which are present above the timing belts. The camshafts control the intake and exhaust valves in your engine so that there is a constant flow of air required for combustion. With the help of the timing belt, the cams can move in the right direction at the right time thereby controlling these valves.

Is It Necessary To Replace Your Timing Belt?

The timing belt of the car engine should be taut enough to control the movement of the pistons correctly. As months pass by and the vehicle is used repeatedly, the timing belt stretches out, cracks, derails or looses teeth and no longer fits tightly in the engine. This can result in a plethora of problems that can damage the engine of the car.

Potential Dangers Of Not Changing Your Timing Belt

When the timing belt is eroded, the timing is out of pace which can cause the valves to hit the pistons leading to serious engine problems. If the timing belt breaks, the pistons keep moving but the valves cease to function. In case you have a clearance engine in your car, the tear of timing belt causes your car to not function at all. This means you will have to end up calling a towing truck to get back to the home, or rather, the mechanic.

On other hand, if you have an interference engine, the resulting damage of a broken timing belt is far greater. The piston ends up hitting the valves causing bent pistons, rods or valves, or even broken ones. This is very hard to repair and costs a lot of money. Sometimes the damage is too expensive and the only way to fix is to replace the engine of the car! You might end up paying even more than the actual value of the car!

Therefore, the best way to avoid any of these engine issues is to make sure your timing belt is maintained.

When Should You Replace Your Timing Belt?

Take action before your timing belt fails and leaves you stranded on the side of the road in the middle of nowhere! Why wait for that final moment when extensive damage can happen to your car. There is no way to know when the belt might fail but it is best to not exceed manufacturer’s recommendations. Most car manufacturers recommend within 10% of the factory interval which falls between 60,000 miles and 100,000 miles or every four years, whichever is sooner.

Some newer car models have manufacturer recommendations up to 120,000 miles! This changing time varies from one car to the other and from one engine to the other. Be sure to check your manufacturer recommended replacement intervals and get your timing belt replaced regularly and by a certified mechanic.

At Rx Auto Repair in St Charles, IL we have all of the manufacturer timing belt change recommendations for all models. If you have any questions, need to schedule an appointment, or need a quote on changing your timing belt – we are here for you.

How Do I Replace My Disc Brake Pads in St Charles IL?

How Do I Replace Disc Brake Pads?

When you notice your front wheels squeaking, it’s time for a change of brake pads. Disc brake
pads wear out gradually over time with the front brakes being affected quickly. Do not wait long
before replacing your brake pads and worn out pads can reduce your car’s ability to stop. Disc
brakes usually include a part called a wear indicator which also indicated when the pads require a
change. Getting your pads replaced at Rx Automotive is a quick and inexpensive maintenance
repair and also provides a great opportunity to get a free brake & tire inspection. However, if you
are the hands on type and have a few hours to kill we have detailed below the proper steps to
change your brake pads yourself.

Tools Required:

  •  Disposable mechanic’s gloves for your hands
  •  Jack and jack stands
  •  Brake pad replacement kit
  •  Lug wrench
  •  Impact wrench
  •  C-clamp
  •  Wrench (choose a socket, open end or adjustable wrench)
  •  Plastic tie, bungee cord or piece of string
  •  High-temperature lubricant
  •  Wire brush

A Step-By-Step Guide of Replacing Your Disk Brake Pads

1. Jack Up The Car
Before you jack up the car, loosen the lug nets in the wheel. This is so much easier when the
wheel is on ground. Jack up the front or rear of the vehicle, using a floor jack, depending on
which brakes you are changing and place the jack stand under the car’s frame. Lower the jack so
that the car rests on the jack stand securely. Never work on a car which is supported by a jack
only! Give a shake to the jack stands to see whether they are holding the car steadily.

2. Remove The Wheel
Finish unscrewing the lug nuts and then remove the tire from the car using a car wrench or an
impact wrench. For safety reasons, you can place the tire under the vehicle’s body to keep the
vehicle off ground in case it falls down. The brake assembly is now exposed. Remove the cap off
the car’s brake fluid reservoir so that you can apply pressure to the piston in the brake caliper

3. Remove The Brake Calipers
Take a wrench and remove the caliper mounting bolts or guide pins. Note which screws are
removed from the caliper and organize them in such a way that you know which one belongs to
the top and which one at the bottom. Lift the caliper off the rotor but since it is still held by the
brake line, use a bungee cord to secure the caliper to a nearby suspension component. In this way
the caliper is safe from any damage which can lead to brakes failure.

4. Remove The Old Brake Pads
Before removing the old pads, push back the piston being careful not to damage bores or the dust
boots. If you notice any metal clips on the brake pads, remove them and then slide the brake
pads right out. Clean the entire caliper and the mount thoroughly with a wire brush and then use
a damp rag to remove any dust or debris.

5. Installing New Brake Pads
You will have to adjust the position of the piston inside the caliper. Place the screw end of the Cclamp
against the piston. When you turn the screw, the clap increases pressure on the piston.
Keep doing so till you install the new pads in the caliper. Re-cap the brake fluid reservoir once
the brake caliper piston has been fully retracted. Place the caliper in position and reinstall any
bolts and guide pins. Put some high temperature lubricant on all sliding metal surfaces.

6. Put Everything Back On
Put the wheel back on, tighten the lug nuts, remove the jack stands and finally lower the car to
the ground using your jack. Make sure you fully tighten the lug nuts with a torque wrench once
the vehicle is placed back on the ground.

7. Put Your Car To A Road Test

Turn the ignition to the normal driving position so that the brake pedal is depressed. Try
releasing and pressing the brake pedal several times so that the piston comes in contact with the
newly replaced brake pads. Take a short drive around the block at low speeds of not more than
25 miles per hour. Brake to see whether the new brake pads have been properly replaced.

Don’t be embarrassed if you don’t know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Saint Charles IL, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three.

As you might guess from the name, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner near your Saint Charles IL home. Your inside wheel has a shorter distance to travel than the outside wheel as you go around the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power. Without a differential, our tires would scrub and hop along the pavement during turns.

You’ve probably noticed the big bugle in the middle of the rear axle when you’re behind a truck. That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complicated. But you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but they need to be properly lubricated in order to stay strong. So from time to time, you need to have your differential serviced. The used fluid is drained and replaced with clean fluid. Some differentials also require special additives to be installed.

Get your differential serviced at our Saint Charles IL service center:

Saint Charles, IL 60174

The rule of thumb for the time and mileage interval for servicing your differential, can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your Saint Charles IL service advisor or your owner’s manual for recommendations.

How and where you drive will have an impact as well. If you drive on dirt roads or through streams around Saint Charles IL, you’ll need to service the differential much sooner than if you always stay on the pavement.
