Maintaining the proper coolant level and regularly inspecting the cooling system for leaks are important for preventing engine damage.

Another important component is the brake system, which includes the master cylinder, brake lines, and brake booster. This system uses hydraulic pressure to apply the brakes, allowing you to slow down and stop the car. The brake booster amplifies the force applied to the brake pedal, making it easier to stop the car. Regularly inspecting the brake pads and rotors, and replacing them when necessary, is crucial for ensuring safe braking performance.

Don't forget the electrical system, which includes the alternator, starter, and wiring harness. The alternator charges the battery while the engine is running, ensuring that the battery has enough power to start the engine the next time. The starter is responsible for cranking the engine when you turn the key. The wiring harness connects all of the electrical components, allowing them to communicate with each other. Maintaining the electrical system is essential for reliable starting and proper functioning of the car's electrical systems.
