What is bleed cooling system?
Bleeding the cooling system is a critical part of any engine installation or engine repair that includes a radiator hose, water pump, or radiator. Once the engine is running, turn the heat to max to allow the coolant to circulate through- out the whole system and eliminate any air pockets.
Is there a way to bleed air out of the cooling system?
To bleed the air out the cooling system you can follow one of three different methods, depending on whether your particular system comes with bleeding screws or not. If you don’t know whether your system comes with a bleeding screw (s), consult your car owner’s manual, or check your vehicle service manual.
Where is the bleed screw on a car cooling system?
The most common place is right on the thermostat housing where the upper radiator hose connects to the engine. If you see an orphaned, single screw, your cooling system has a bleed screw—some systems come with more than one bleed screw, though. Check your car owner’s manual or repair manual, if necessary.
What to do when your car’s cooling system bleeds?
When you see a stream of coolant free of air bubbles flowing from under the screw, tighten the screw again. Turn off the engine and wait for it to cool. Add more new coolant to the radiator—up to the bottom of the radiator neck—and the reservoir, if necessary. Test-drive your car and see if the temperature stays within the normal parameters.
What’s the difference between manual and air bleed?
The manual method is the old style variant of bleeding the coolant system. Some cars have an air bleed valve to get the air out from the system, and some cars don’t have this air bleed valve which makes it a lot more difficult. However, the method for both of them is the same.

There are two other methods available for bleeding air from your cooling system. Some vehicles actually have bleeder valves specifically for this problem, located at the top or in front of the radiator. Open the valve and bleed the air trapped in the upper portion of the radiator. You can also jack your car to bleed the air from the cooling system.
