A gear ratio is the relationship between the rotation of the input gear (engine output) and the output gear (wheels). Essentially, it determines how many times the engine needs to turn for the wheels to complete a full rotation. A gear ratio calculator is a tool that can easily determine this ratio, simplifying maintenance decisions and enhancing your car’s performance.

Electric cars do have transmissions, but not in the traditional sense. Unlike conventional cars that use multi-speed transmissions, most electric vehicles utilize a single-speed transmission or direct drive. This mechanism simplifies power delivery, increasing efficiency and reducing maintenance needs.

The serpentine belt is a long, winding belt that powers key parts of your vehicle, like the alternator, power steering pump, and air conditioning compressor. It’s called ‘serpentine’ because it snakes around these components. However, it can wear out or become loose over time, and that’s when problems can start.

The output shaft is a key part of the transmission system that transfers the rotational force from the engine to the wheels. Its function is pivotal, as it effectively converts and channels the power generated by the engine into motion that propels the vehicle.

A transmission fluid flush is a comprehensive process that cleanses the transmission system by replacing old fluid with new. It’s more thorough than a transmission fluid change, which usually leaves some old fluid in the system. The cost varies, typically ranging from $100 to $300, depending on several factors.

The catalytic converter cleans up harmful gases before they leave your exhaust pipe. It’s a crucial part of your car that keeps the air cleaner and helps your car run smoothly. When it goes bad, it can cause a lot of problems, both for your car and for the environment.

Automatic transmission fluid is a special lubricant used in vehicles with self-shifting or automatic transmissions. It comes in different types such as:

If your car’s engine misfires, you may notice unusual noises, car shaking, decrease in power, poor fuel efficiency, and a check engine light. If you notice any of these signs, it could be due to spark plugs, fuel system, or engine timing.

An internal combustion engine is a complex machine that generates power by burning fuel within its structure, rather than externally. The fuel-air mixture’s combustion, initiated by a spark plug, causes a high-pressure gas expansion that pushes a piston. This mechanical motion is ultimately converted into the rotational movement of the wheels.

The Exhaust Gas Recirculation (EGR) valve plays a role in maintaining your car’s engine performance and reducing harmful emissions. It’s a component that doesn’t often come to mind when considering vehicle maintenance, yet its failure can result in serious engine issues, potentially escalating costs and even environmental damage.

The Ford Fusion has been a popular midsize sedan since its introduction in 2006. With its stylish design and comfortable ride, the Fusion has attracted many loyal fans over the years. However, not all model years have been created equal. Some years stand out as the best, while others are best avoided due to various issues.

A gear shift is a component in vehicles that allows the driver to control the transmission system. It alters the vehicle’s gear ratio, changing its speed and torque. In simpler terms, the gear shift helps your car go faster, slow down, and climb hills without straining the engine.
