What is the part of the car that cools the engine?

Question

Sorry... I'm not good at car stuff.

Answer 1

The Radiator. (Located behind the grille).

Coolant (Green, red, or yellow, depending on the vehicle) is pumped from the engine through the radiator by the water pump. The Radiator is comprised of thin metal fins that, when the hot coolant flows through, discipates the heat from the coolant. The coolant is then pumped back to the engine and the cycle repeats itself.

Immediately behind the front grille of a car you will find a black painted radiator with a large hose leading to the top of the motor.

The motor has cooling passages throughout the block and cylinder heads. A water pump is driven by that confusing crazy belt on the side of the motor if you have a front wheel drive car it faces the radiator. The belt and water pump is on the front facing the radiator if your car has rear wheel drive. The radiator has a pressure cap on one side or in Fords case, the radiator cap on the coolant recovery tank.

We use a mixture of 50 % distilled water and 50% antifreeze mixed together poured into the radiator and the coolant recovery tank. As soon as you start your car the coolant starts to slowly circulate through all the coolant passages through the motor because the water pump circulates it. When the coolant (antifreeze / water) reaches a temperature hotter than the thermostat the coolant moves faster through the cooling system. The radiator pressure cap raises the boiling point of the coolant. If you have a 16 lb. pressure cap coolant will not boil till it reaches + 265 degrees F. There's a popular misconception that antifreeze and water will raise the boiling point of water. This is completely false.

The hot water is pumped into the bottom of the radiatiator. While the coolant travels back and fourth inside theradiator the coolant cools off do to the comb fins that touch each individual cooling tube. As the coolant temperature reaches a certain setpoint the radiator electric fan starts and pulls air through the radiator to lower the temperature of the coolant.

As you drive your car the front of the car creates a high pressure area and air is forced in do to the movement of the car. That helps cool the coolant even more.

Hope this explains how and why the system works.

Answer 3

Most cars - the only exception is air-cooled engines like some disfunctional porsches and old vw's which use air flow - have quite sophisticated cooling system that uses coolant flow through the engine's water jacket. The radiator - as somebody already mentioned - is a very important but not the only component of the cooling system. There is a thermostat that provides automatic coolant flow adjustment to keep engine temperature @ 195-200 deg F which is optimal for normal operation, there also is a water pump that provides coolant circulation. There also is a forced air circulation systme that usually involves two electric fans (on some vehicles, there is one mechanical, and one electric fan while on older vehicles, there is only one mechanical fan) that kick in when engine temp reaches certain (around 210-220 deg) temperature, and when air conditioning is activated.
Each and every one of these components is absolutely essential for engine to operate, and failure of one of them usually causes overheat and subsequent severe engine damage.

Answer 4

there are a few components involved here. First you have the radiator which holds the coolant. then there is the water pump which circulates the coolant through the engine. The thermostat regulates the temperature of the engine by opening and closing to keep the engine coolant a constant temperature. then there is the fan...a very important component...on the older models the fan was attatched to the front of the water pump...and in most cases was a clutch fan...in the newer models it is an electric fan which is attatched to the radiator and is operated by way of a coolant sensor switch. When all of these components are working properly the engine runs at optimum temperature and at peak performance.

Hope this helped ya

Answer 5

The radiator is the main cooling device used, in the front of the car. You can also use the heater to cool the car, but it has a much smaller mini-radiator, called a heater core, so would take longer. But, if your car is overheating in the summer, and you have no other option, you can turn the heat on, and it'll help out in an emergency. But the main radiator ( radiates heat ) is the main device used to cool the car.

Answer 6

I have a 1986 Volkswagen and the fan went on it last summer and i could not keep it cooled,as long as i was moving it was fine.I later decided to go to a thinner oil and i found it helped alot and doesn't run as hot anymore.

Answer 7

The radiator.

Answer 8

Radiator and fan(s).
