Engine oil lubricates the engine’s moving parts and comes in various viscosities. The amber color and viscosity numbers on the bottle are the biggest giveaways.Spark plugs ignite the air-fuel mixture in gasoline engines. The ceramic body and electrode tip are distinctive.Wiper blades clear water and debris from the windshield. The rubber edge and metal frame are instantly recognizable.This fluid is specifically formulated to clean the windshield and resist freezing. The blue or purple color is the classic visual cue.Brake pads are the friction material that presses against the rotor to slow the vehicle. They are rectangular or slightly curved and made of composite material.Coolant (antifreeze) regulates engine temperature. The bright colors and “coolant” or “antifreeze” labeling make it unmistakable.The oil filter removes contaminants from the engine oil as it circulates. It is almost always a spin-on metal canister or a cartridge style.The alternator recharges the battery and powers the electrical system while the engine is running. The pulley and wiring terminals are key identifiers.The 12-volt battery provides the initial electrical power to start the engine and run accessories when the engine is off.The rotor is the rotating disc that the brake pads squeeze. Most modern cars use disc brakes on at least the front wheels.The oil dipstick is the most common tool for checking engine oil level. It is usually yellow or brightly colored for easy identification.The engine air filter cleans the air before it enters the engine. Its distinctive pleated paper design is easy to recognize once you’ve changed one.The catalytic converter reduces harmful exhaust emissions. It is typically a larger metal canister in the exhaust system.The serpentine belt drives multiple accessories (alternator, power steering, A/C) with a single long ribbed belt.Radiator hoses carry coolant between the engine and radiator. They are thicker and more rigid than most other hoses under the hood.This reservoir holds the hydraulic fluid that powers the brakes. It is almost always marked “Brake Fluid” and sits near the master cylinder.The cabin air filter cleans the air that enters the passenger compartment through the HVAC system.The timing belt synchronizes the crankshaft and camshaft(s). It has teeth to prevent slipping and is a critical maintenance item.This hydraulic fluid helps the power steering system operate smoothly. It is usually stored in a dedicated reservoir near the firewall.ATF lubricates and cools the automatic transmission. The distinctive red color is a classic identifier.The boot protects the connection between the spark plug and the ignition wire or coil-on-plug unit from moisture and dirt.These small seals prevent oil leaks at the filter or drain plug. They are inexpensive but essential during oil changes.This is where you pour new engine oil. The oil symbol or the word “Oil” makes it easy to spot.The radiator cap maintains pressure in the cooling system. It is usually marked with a pressure rating (e.g., 16 psi).This flexible tube carries clean air from the air filter to the engine. Cracks or loose clamps here can cause performance issues.The fuel filter removes dirt and debris from the fuel before it reaches the injectors or carburetor.The CV boot keeps grease in and contaminants out of the constant-velocity joint. Torn boots are a common maintenance item.Shocks and struts control the bounce and ride quality of the suspension. They are one of the most frequently replaced suspension parts.Coil springs support the vehicle’s weight and absorb road impacts. They are visible on most independent suspension systems.The Positive Crankcase Ventilation (PCV) valve routes blow-by gases from the crankcase back into the intake system so they can be burned instead of released into the atmosphere.The thermostat is a temperature-sensitive valve that opens and closes to regulate coolant flow, helping the engine reach and maintain its proper operating temperature.The water pump circulates coolant through the engine and radiator to keep the engine from overheating.The starter motor turns the engine over when you turn the key or press the start button so the engine can begin running on its own.Ball joints allow the suspension to move up and down while the wheels steer. They are critical safety items.Tie rods transmit steering input from the rack (or gearbox) to the wheels. Inner and outer tie rods are common replacement parts.The valve cover gasket prevents oil from leaking out of the top of the engine. It is a frequent source of oil leaks on higher-mileage vehicles.The head gasket is one of the most important seals in the engine. Failure can cause coolant and oil to mix or loss of compression.The gas cap keeps fuel vapors contained and maintains proper pressure in the fuel system. A loose or missing cap can trigger a check-engine light.The oxygen sensor measures the amount of oxygen in the exhaust so the computer can adjust the air-fuel mixture. It is a common replacement part on higher-mileage vehicles.The fuel pump moves gasoline or diesel from the fuel tank to the engine so the injectors or carburetor can deliver the correct amount of fuel.You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
