How does a car radiator work?

Question

I need a detail description on how a car radiator works please

and can you also tell me exactly where its located. AS SPECIFIC AS POSSIBLE

Answer 1

It's usually located dead center, directly behind the grille, at the very front of the car.

It works by a combination of heat conduction and wind chill. Coolant is pumped through passageways in the engine, where it soaks up some of the heat from the engine. It continues through the passageways, then enters the radiator through a large rubber hose. Here, the air blowing through the radiator cools the liquid inside (a fan blows the are through the radiator), and the now-cool (or at least cooler) lliquid is repumped back into the engine to start the process all over again. It's a circular process of taking heat from the engine, releasing it through the radiator, and returning to the engine again.

Answer 2

1st, a water pump moves water through the engine block where it surrounds the cylinder. The water is heated by the combustion within the cylinders and is pumped into the radiator. The radiator is made of aluminum, (used to be brass) and has two tanks with tubes between. The heated water moves through the tubes where the outside air cools it down. Then the cycle is repeated. The radiator is usually located at the front of the car where fresh air is available. Hope that helps.

Answer 3

If the radiator is a top flow design, hot water from the engine flows into the top chamber of the radiator. From there it flows down the cooling tubes to the bottom chamber. Inbetween the tubes are zigzag fins. The fins touch the tubes and help carry the heat away. The radiator fan sucks outside air through the fins and cools them. The water pump connects to the bottom chamber and sucks the cooled fluid into the engine.

In a side flow design, the chamber are located on the sides of the radiator. The fluid flows horizontally throught the tubes. Hot coolant in one side, cooled coolant gets sucked out the other. The advantage of the side flow is that the coolant stays in contact with the tubes longer and thus can remove more heat.

Answer 4

The radiator is generally located at the front of the engine
compartment where it can get good air flow.
It works by exposing tubes through which engine coolant flows
to the air-stream, thus cooling the fluid and finally the engine.
The water pump forces coolant through the engine
collecting waste heat, then through the radiator
which rejects the heat to the outside air.

Answer 5

it is locate directly behind the grill in the front of the car. what a radiator does is dispels the heat from the coolant so the engine does not get to hot. as you are driving the coolant is going through the fins of the radiator and the fan pulls cooler air through the fins to cool down the anti freeze in the radiator

Answer 6

hot engine coolant engine goes into the top of the radiator flows downward to the bottom ...along the way it is air cooled by the forced air flow by the movement of the vehicle or by an electric fan, the cooled down coolant goes back into the engine to remove more heat from the hot engine... and this cycle continues as long as the hot engine is running
