Test your automotive knowledge! This worksheet covers essential car parts, systems, and common troubleshooting scenarios. Complete each section to the best of your ability.
Part 1: Match the Function
Match the car part in Column A with its primary function in Column B. Write the correct letter in the blank provided.
| ____ 1. Alternator | A. Dissipates heat from the engine coolant to prevent overheating. |
| ____ 2. Transmission | B. The "heart" of the car; converts fuel into mechanical motion. |
| ____ 3. Catalytic Converter | C. Creates friction against the brake rotors to slow or stop the vehicle. |
| ____ 4. Suspension | D. Converts engine power into a usable range of speeds and torque for the wheels. |
| ____ 5. Brake Pads | E. A system of springs and shock absorbers that connects a vehicle to its wheels. |
| ____ 6. Radiator | F. Generates the electrical spark that ignites the air-fuel mixture. |
| ____ 7. Spark Plug | G. Reduces the toxicity of harmful pollutants in exhaust fumes. |
| ____ 8. Engine | H. Charges the battery and powers the vehicle's electrical systems while running. |
Part 2: System Breakdown
Fill in the blanks below to complete the description of a car's cooling system using the words from the word bank.
- coolant
- thermostat
- radiator
- water pump
- hoses
A car's engine generates immense heat, and the cooling system prevents it from overheating. The is the heart of this system, circulating liquid throughout the engine block to absorb heat. This hot fluid then travels through to the , located at the front of the car, where airflow cools it down. A device called the acts like a valve, controlling the flow of the liquid based on its temperature to ensure the engine warms up quickly and maintains an optimal operating temperature.
Part 3: What's the Problem?
Read the following scenarios and identify the most likely part or system that is causing the issue.
- You hear a high-pitched squeal every time you apply the brakes, especially when stopping gently. The noise goes away when you are not braking.
- Your car's headlights seem dim, and when you try to start it, you hear a rapid clicking sound but the engine doesn't turn over.
- Your car feels unusually bouncy and sways significantly when you drive over bumps or turn a corner. It feels less stable than it used to.
- While driving, you notice the temperature gauge on your dashboard has climbed into the red "H" zone and you see steam coming from under the hood.

- E. A system of springs and shock absorbers that connects a vehicle to its wheels.
- C. Creates friction against the brake rotors to slow or stop the vehicle.
- A. Dissipates heat from the engine coolant to prevent overheating.
- F. Generates the electrical spark that ignites the air-fuel mixture.
- B. The "heart" of the car; converts fuel into mechanical motion.
Part 2: System Breakdown
A car's engine generates immense heat, and the cooling system prevents it from overheating. The water pump is the heart of this system, circulating liquid coolant throughout the engine block to absorb heat. This hot fluid then travels through hoses to the radiator, located at the front of the car, where airflow cools it down. A device called the thermostat acts like a valve, controlling the flow of the liquid based on its temperature to ensure the engine warms up quickly and maintains an optimal operating temperature.
Part 3: What's the Problem?
- Worn out brake pads (the squeal is from the wear indicator).
- A dead or weak battery (and/or a failing alternator that isn't charging the battery).
- Worn out suspension components (specifically shock absorbers or struts).
- An overheating engine, likely caused by a problem in the cooling system (e.g., low coolant, bad thermostat, radiator fan failure).
