A
This part of the vehicle touches the road and is located closest to the engine in most cars.
Front wheel
This metal part of a wheel holds the tyre
Rim
The driver looks at this part to see the speed, warning lights and fuel level.
Dashboard
A short written message containing information that you should remember.
Note
You see this word when you must be careful because something could be dangerous.
Caution
...........gases leave the vehicle through this metal ............
Exhaust pipe
These parts press against the brake disc to create friction and slow the vehicle down. They become thinner through use
Brake pads
This liquid fuel gets its name from a German engineer who developed a special type of engine.
Diesel
This liquid circulates through the engine’s system and helps prevent overheating
Coolant
This problem occurs when a liquid or gas escapes from a system through a hole, crack or damaged seal.
Leakage
This is the problem or symptom that the vehicle owner reports to the workshop.
Customer complaint
A cleaning product used in the workshop to remove dirt, oil (among other things) from parts or surfaces.
Degreaser
When the driver presses the brake pedal, this liquid transfers the pressure through the braking system.
Brake fluid
This process slowly damages metal through a chemical reaction. Rust is a common example.
Corrosion
This electrical value is measured in volts and describes the potential difference between two points in a circuit.
Voltage
A technician uses this diagnostic instrument to measure electrical values such as resistance, current and potential difference.
Multimeter
This corrosive electrolyte is found in a traditional lead-acid battery and consists mainly of sulphuric acid mixed with water.
Battery acid
This is the turning force produced by an engine or applied when tightening a bolt. It is often measured in newton-metres.
Torque
This part is driven by the engine and produces electricity while the engine is running. It also helps to charge the battery.
Alternator
This organised group of electrical wires and connectors carries power and signals to different parts of the vehicle.
Wiring harness
This electrical problem occurs when a component continues to use power after the vehicle has been switched off, causing the battery to become empty.
Parasitic drain
This electrical fault happens when current takes an unintended path with very little resistance, which can cause excessive current.
Short circuit
This engine problem occurs when the air-fuel mixture in one or more cylinders does not burn correctly.
Misfire
This component allows the wheel to rotate smoothly with little friction. When it is worn, you may hear a humming or grinding noise while driving.
Wheel bearing
This component delivers a controlled amount of fuel into the engine as a fine spray.
Fuel injector
