Use a penny to undo bottom hose and take the cap off.
If you're referring to automobile radiators, most have a petcock at the bottom that can be unscrewed with the hand to drain the radiator.
How do you bleed air from radiator of a 2000 range rover?
next to the radiator cap on top of the radiator
Of course
The first step that you can take to fix a radiator is to see if it needs to be bled. To bleed a radiator you will need a radiator bleed key. Unscrew the valve at the side of the radiator and when the first drop of water comes out, close the valve again. If this does not fix the radiator you will need to call in a plumber.
You shouldn't need to "bleed" the radiator in your Forester. If you top off the coolant in the radiator the next time you check the top of your radiator is empty again? You have a blown head gasket. Voice of experience here. --Ken
NO!!!!!
no air bleed valve. all you need to do is to remove the radiator cap and let the car idle for a few minutes.
At the bottom of the radiator, you can see it from under the truck.
To bleed the cooling system on a Pontiac 2.4 engine, there is a small hose near the bottom of the radiator that needs to be removed. Then remove the radiator cap and the cap on the radiator overflow tank.
The cooling system bleed valve, on your General Motors 5.7 liter engine, is located on the bottom of the radiator. The bleed valve should be in the middle of the radiator bottom.
It is not necessary to bleed the coolant system. If you mean "drain" the system, there is usually a plastic plug on the radiator or, you can pull the lower radiator hose off.
its a valve to let the air out of the system
