parts under the hood

Question 1

transmission

Answer 1

is placed under everything else and won’t be visible from the top. The transmission’s job is to make sure all the power goes to the wheels to drive at any given speed. It works when you shift the gears.

Question 2

fuse box

Answer 2

the fuse box is in control of the electrical system.

Question 3

intake hose

Answer 3

it is the part where it connects the air filter box to the vehicle’s throttle body.

Question 4

air filter box

Answer 4

collects air from outside and feeds it to intake hoses of each cylinder.

Question 5

air intake

Answer 5

to allow air to reach your car engine and cleans the air

Question 6

battery

Answer 6

is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

Question 7

anti freeze coolant cap and reservoir

Answer 7

a vital component of the cooling system. Its function is to store excess coolant fluid until required.

Question 8

throttle body

Answer 8

the part of the air intake system that controls the amount of air that flows into an engine’s combustion chamber. … When the gas pedal is released, the butterfly closes and effectively chokes off (throttles) air flow into the combustion chamber.

Question 9

breather hose

Answer 9

allows an internal combustion engine to vent crankcase pressure out of the engine. … By venting pressure out of the crankcase, an engine’s piston rings are allowed to seal tighter against the cylinder walls. This provides better compression and promotes less oil consumption while making more horsepower.

Question 10

valve cover

Answer 10

is a casing found on the top of the engine. It covers the valves of the engine, protects the machinery from the elements, and prevents oil leaks. Cracks, corrosion, and misalignment of the valve cover can cause fluid to leak into the engine compartments and lead to engine failure.

Question 11

spark plugs

Answer 11

are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes your engine produce power. These small but simple plugs create an arc of electricity across two leads which are not touching, but close enough together that electricity can jump the gap between them.

Question 12

headers

Answer 12

is to make it easier for the engine to push exhaust gases out of the cylinders. … In a normal engine, once the exhaust gases exit the cylinder they end up in the exhaust manifold.

Question 13

radiator

Answer 13

transfers the heat from the fluid inside to the air outside, thereby cooling the fluid, which in turn cools the engine.

Question 14

strut

Answer 14

provide support to the suspension springs. Their main job is to act as shock absorbers to support the weight of the vehicle and ensure a smooth ride.

Question 15

oil cap

Answer 15

The purpose of the oil inside the engine is to lubricate the parts and cools it down if the engine overheats. Some of the components like rings, pistons, valves and nozzles heat up when running for long. The oil regulates the temperature of the engine, keeping it normal.

Question 16

dip stick

Answer 16

can also be used to measure the quantity of liquid in an otherwise inaccessible space, by inserting and removing the stick and then checking the extent of it covered by the liquid.

Question 17

windshield fluid

Answer 17

contains ingredients that are meant to clean up those stubborn messes. Most products are made of methanol and other alcohols like ethylene glycol. … The ingredients in washer fluid work together to give you a clean, streak-free windshield no matter how cold it is outside.

Question 18

brake fluid

Answer 18

helps transfer the movement and force created when you press down on the brake pedal. Adding brake fluid is usually not part of routine vehicle maintenance. Low brake fluid typically means that your brake pads are worn and will soon need to be changed.

Question 19

alternator

Answer 19

turns mechanical energy into electrical energy which gets directed to the battery and goes on to power all your car’s electrical systems. Even though the car’s battery gets all the credit for powering electrical systems, the truth is that the alternator provides the energy while the vehicle is running.
