The engine is the heart of your car. It is a complex machine built to convert heat from burning gas into the force that turns the road wheels.

The SRT is the top-of-the-line Dodge Challenger. The rules for changing the oil are the same as they are for every vehicle. You should change the oil in your Challenger every 3,000 miles to keep it from breaking down and causing the engine to run without lubrication. It's also important to change the oil filter, as the old filter is contaminated and needs to be removed so it does not contaminate the new oil.

Most modern cars have brakes on all four wheels, operated by a hydraulic system . The brakes may be disc type or drum type.The front brakes play a greater part in stopping the car than the rear ones, because braking throws the car weight forward on to the front wheels.Many cars therefore have disc brakes , which are generally more efficient, at the front and drum brakes at the rear.

The air-conditioning system in your Ford is basically a circulation loop through which refrigerant is pumped by a compressor. The refrigerant is a combination of gas and liquid that becomes very cold as it is compressed and then expanded. The chilled gas then flows from the compressor into an evaporator coil. The cold refrigerant now inside the coil has air blowing across the fins and tubes of the coil, thereby cooling the air, which is transferred into the car.

There are different applications of coil spring suspension. On most front-wheel-drive cars, coil springs are assembled to the strut, coiling around it. Heavier-duty vehicles place coils between the chassis and the frame and feature shocks as a separate suspension component.

Regular oil and filter changes are the single best thing you can do to keep your vehicle running smoothly for many years. By regularly changing your own oil, you save money as you extend your car’s life by thousands of miles. Oil changes are something any DIYer can do. Once you have all the equipment on hand, you can change the oil in most cars in about 20 minutes.

The oil filter gets contaminants out of engine oil so the oil can keep the engine clean, according to Mobil. Contaminants in unfiltered oil can develop into hard particles that damage surfaces inside the engine, such as machined components and bearing surfaces.

Most brake calipers do not need to be rebuilt or replaced the first time the brakes are relined. But after 75,000 miles, or seven to 10 years of service, the calipers may be reaching the end of the road. As the rubber seals age and harden, the risk of sticking and leaking goes up.

If you're not experienced with vehicles, you may not realize there are two different types of brake calipers. One is floating and the other is fixed. Even though they don’t need maintenance, their failure is common. These guidelines will help you figure out how to change brake calipers.

Removing the steering wheel from your car or truck is not a difficult task if you have the right tools, particularly a steering wheel puller. But if you don't have a steering wheel puller, taking off the steering wheel becomes a bit trickier. You have to be a bit more creative than you would be under normal circumstances and employ a few nontraditional methods, but it can still be done at home with a few more common tools.
