What is the temperature difference between the top rad hose and the bottom hose?
A temperature difference of about 10-20 degrees Fahrenheit between the top radiator hose and the bottom hose is normal when the engine is running. The top hose carries hot coolant from the engine to the radiator, while the bottom hose returns cooler coolant back to the engine. This temperature variance helps the engine maintain proper operating temperature.
Why radiators hot on the bottom but cold at the top?
Radiators are typically hot at the bottom because that is where the hot water or steam enters the radiator. As the water or steam travels up through the radiator and gives off heat, it gradually cools down which is why the top of the radiator feels cooler. This process is important for efficient heat distribution in a room.
Why does the radiator get hot at the top but not the bottom?
The hot water that enters the radiator rises to the top as it is lighter and less dense than the cooler water at the bottom. This creates a temperature difference between the top and bottom of the radiator. Heat is transferred from the hot water to the radiator fins, which in turn heats the surrounding air.
Why is the top of your refrigerator cold but not the bottom part?
The top of the refrigerator is cold because that's where the cooling unit is located, usually at the back. The cold air sinks, so it tends to stay at the bottom of the fridge where it keeps the food cool.
Are compressors supposed to be cold from top to bottom?
In general, compressors should be cooler at the top than at the bottom. This is because the cooling system typically starts at the top and moves downwards to prevent overheating. If a compressor is uniformly cold from top to bottom, it may indicate a cooling system issue or inefficient heat dissipation.
Where is the radiator hose?
Look on top of the radiator and follow the hose from the radiator to the thermostat housing. Look on the bottom of the radiator and follow the hose up to bottom of the block.
Where is the radiator hose located?
Look on top of the radiator and follow the hose from the radiator to the thermostat housing. Look on the bottom of the radiator and follow the hose up to bottom of the block.
Why is top radiator hose hot and the bottom hose cold in 1989 Toyota pickup?
Engines return hot coolant to the radiator through top hose, and cooled coolant goes back to the engine through the bottom hose, so a difference in temperature between the two would not be unusual. Assuming you have allowed the engine to come up to temperature and the bottom hose is stone cold, either the radiator or bottom hose is blocked, the water pump has failed or there is an air lock. A seized viscous coupling on a cooling fan or a permanently running electric fan can also make the radiator over-cool, but the bottom hose would feel slightly cooler than the top hose, not cold.
Does the radiator on a 1999 mercury mountaineer come out from the top or bottom?
When the thermostat is open the coolant will flow through the top radiator hose in to the radiator and out to the water pump through the bottom radiator hose
Which is the upper or lower radiator hose on Jeep Cherokee?
Upper is hose connected to top of radiator, lower is hose connected to bottom of radiator.
How do you know if you have a bad water pump in your car?
what if my top radiator hose is very hot and the bottom hose is cold,would that be a bad water pump?
Where is the main radiator hose on a 2000 Chevrolet Monte Carlo?
There's a top hose (the one on top) and a bottom hose. (the one on the bottom) There is no main hose.
Where is the rad hose?
The radiator hose which I assume you mean although you write rad, is connected to the radiator. One on the top of the radiator and one on the bottom. the one on the top
What are the step to Flushing a 2000 DTS Radiator?
Remove the bottom radiator hose. Put a garden hose into the top of the radiator. Allow the garden hose to run until the water coming out of the bottom of the radiator is clear.
Does the thermostat connect to the bottom radiator hose on a 1996 Toyota corolla?
The thermostat connects to the top radiator hose on a 1996 Toyota Corolla. The bottom radiator hose connects to the water pump.
How do you drain the radiator on a Fiat Punto SX R reg?
punto sx radiator drainingRadiator has two hoses. One at the top of the radiator,(The top hose) and a hose at the bottom of the radiator (The bottom hose). Wait until the engine is cool. You need to undo the expansion tank screw top (where you top up the radiator)then release the bottom hose clip (use a screw driver)which allows you to pull off the hose from the radiator expansion tank adjoining the radiator. Make sure you have a bowl underneath to catch the water.
How do you flush the radiator fluid in a 97 Geo Prism?
Remove the bottom radiator hose. Stick a hose in the top of the radiator. Turn the water on. Allow the water to run through the radiator and out the bottom of the radiator.
