The driveshaft is a tubular steel or aluminum shaft that transmits torque from the transmission output to the differential, which then sends power to the wheels. It is critical in rear-wheel and four-wheel drive vehicles. Driveshafts must accommodate suspension movement and maintain balance at high speeds. For more information see Wikipedia.
Which part cools engine coolant by transferring heat to the air?
Radiator
Water Pump
Oil Cooler
Intercooler
The radiator is a heat exchanger that transfers heat from the engine coolant to the outside air, cooling the fluid before it returns to the engine. It consists of a core with fins that increase surface area for efficient heat dissipation. Coolant is circulated through the radiator by the water pump. Learn more at Wikipedia.
What is the function of the spark plug in an internal combustion engine?
Ignite the air-fuel mixture in the combustion chamber
Measure oxygen content in exhaust gases
Control engine temperature
Lubricate the cylinder walls
A spark plug generates a high-voltage spark to ignite the compressed air-fuel mixture inside the engine’s combustion chamber, initiating the power stroke. Proper spark plug function is essential for efficient combustion, power, and fuel economy. Spark plugs must withstand extreme heat and pressure and are periodically replaced. More details at Wikipedia.
Which component in the exhaust system converts harmful gases into less toxic substances?
Catalytic Converter
Muffler
Exhaust Manifold
Resonator
The catalytic converter uses catalysts like platinum and palladium to convert toxic exhaust gases (CO, NOx, hydrocarbons) into less harmful substances (CO2, N2, H2O). It’s a key emissions control device on modern vehicles. The converter operates effectively at high temperatures once the engine warms up. See Wikipedia for more.
Which part seals the top of the engine block and contains the combustion chambers, valves, and often camshafts?

The power steering pump pressurizes hydraulic fluid that assists the driver in turning the steering wheel, reducing effort. It is belt-driven by the engine and circulates fluid through the steering gear. A failing pump can cause heavy steering or noises. Details at Wikipedia.
Which part clamps onto the brake rotor to slow and stop the vehicle?
Brake Caliper
Brake Pad
Brake Shoe
Master Cylinder
The brake caliper houses the brake pads and uses hydraulic pressure to press them against the spinning rotor, creating friction that slows the wheel. It is a vital part of a disc braking system. Calipers must remain leak-free and slide smoothly. More information at Wikipedia.
Which belt ensures synchronization between the camshaft and crankshaft rotations?
Timing Belt
Serpentine Belt
V-Belt
Alternator Belt
The timing belt has teeth that mesh with gears on the camshaft and crankshaft, ensuring valves open and close in precise relation to piston movement. If it breaks, severe engine damage can occur. Many manufacturers recommend periodic replacement. See Wikipedia.
What component regulates coolant flow to maintain the engine’s operating temperature?
Thermostat
Radiator Cap
Water Pump
Coolant Reservoir
The thermostat is a temperature-sensitive valve that stays closed when the engine is cold to allow it to warm up quickly, then opens to permit coolant flow through the radiator. This regulates engine temperature within an optimal range. A stuck thermostat can cause overheating or poor performance. More at Wikipedia.
Which part converts electrical energy into mechanical energy to initiate engine cranking?
Starter Motor
Alternator
Ignition Coil
Starter Relay
The starter motor is an electric motor that engages the engine’s flywheel to crank the engine and start combustion. It draws high current from the battery and engages via a solenoid. A failing starter can produce clicking sounds or no response. Details at Wikipedia.

Oxygen Sensor
Mass Air Flow Sensor
Throttle Position Sensor
Knock Sensor
The oxygen sensor, or O2 sensor, detects oxygen levels in exhaust gases and sends data to the ECU to adjust the air-fuel ratio for optimal combustion and emissions control. It’s typically located before and after the catalytic converter. A faulty sensor can trigger check-engine lights and poor fuel economy. See Wikipedia.
What component filters out dust and debris from air entering the engine?
Air Filter
Fuel Filter
Oil Filter
Cabin Filter
The air filter removes contaminants such as dust, pollen, and debris from incoming air before it enters the engine’s intake, protecting internal components and ensuring efficient combustion. Most air filters are made of pleated paper or foam. A clogged filter can reduce power and fuel economy. More at Wikipedia.
Which device pressurizes fuel before it is delivered to the injectors?
Fuel Pump
Fuel Rail
Carburetor
Throttle Body
The fuel pump draws gasoline from the tank and pressurizes it to the level required for the injectors to atomize the fuel in the intake manifold or combustion chamber. Modern vehicles use electric in-tank pumps, while older designs may use mechanical pumps. Low fuel pressure can cause misfires and stalling. See Wikipedia.
Which part maintains a constant voltage level in the vehicle’s electrical system?
Voltage Regulator
Battery
Alternator
Fuse Box
The voltage regulator controls the output of the alternator to maintain a stable voltage (typically around 13.8–14.4 volts) in the vehicle’s electrical system. Proper regulation protects electronic components from over- or under-voltage. Regulators can be internal or external to the alternator. Learn more at Wikipedia.
In front-wheel-drive vehicles, which component transfers torque from the transmission to the wheels while allowing for steering angles?
CV Axle
Driveshaft
Differential
Wheel Hub
A Constant Velocity (CV) axle, or half-shaft, transfers engine torque from the transaxle to the wheels while accommodating up-and-down suspension movement and steering angles. CV joints at each end allow smooth power transfer without vibration. They require protective boots and lubrication. Details at Wikipedia.
Which component converts mechanical energy from the engine into electrical energy to charge the battery?
Alternator
Generator
Starter Motor
Ignition Coil
The alternator is driven by a belt connected to the engine and uses electromagnetic induction to generate alternating current, which is then converted to direct current to recharge the battery and power electrical systems. Modern alternators include built-in voltage regulators. Learn more at Wikipedia.
