The water pump circulates it through and it either goes across or down then back into engine.
It is a matter of density cold water is denser(compact) that hot water. thus cold water will flow faster than less dense(loose)hot water.
no
The hot water heats the metal of the radiator, which heats the surrounding air. The warm air circles round the room.
There are pipes that feed from radiator to radiator. Or there can be multiple feed pipes and return pipes, it varies based on installation.
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
Once the thermostat has opened, the hot coolant flows from the thermostat housing on the engine into the top of radiator and out the bottom of the radiator back into the water pump.
I expect the radiator sensor you have in mind is the water temperature sensor, which is often not in the radiator at all, but in the engine block controlling the water flow to the radiator. They usually have a wax capsule that expands when hot, and opens the water valve. If it gets too hot, it fails. But a thermostat is quite cheap. A new gasket is a good idea too.
Coolng fan not working?Radiator or air flow plugged?Water pump not rotating fast enough?Defective radiator cap?
Your water flow comes out of the engine through the upper hose, into the radiator. The lower hose is cooler because the radiator has done its job; it cooled the water!
It is a matter of density cold water is denser(compact) that hot water. thus cold water will flow faster than less dense(loose)hot water.
from the top to the bottom
no
the radiator will spew hot water on you
remove your radiator form your car then poor some hot water in radiator till water comes out nice and smooth.
When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.
The hot water heats the metal of the radiator, which heats the surrounding air. The warm air circles round the room.
The radiator cools the water which then goes to your engine to cool it off, as cool water enters your engine hot water from the engine enters your radiator
