On 3.9L engines
1. Remove the engine fill cap.
2.. Open the heater air bleed.
3. Add coolant to the degas bottle allowing the system to equalize until no more coolant can be added.
4. Replace the degas bottle cap.
CAUTION: Care must be taken to ensure the accessory drive belt does not become contaminated with engine coolant.
5. Add as much coolant as possible to the engine fill. The heater air bleed will remain open.
6. Replace the engine fill cap.
7. NOTE: The heater air bleed remains open.
Start the engine and turn the heater to MAX position.
8. Close the heater air bleed when a steady stream of coolant comes from it, during engine idle.
9. Allow the engine to idle for five minutes, add coolant to the degas bottle as needed to maintain the cold fill MAX mark.
10. Reopen the heater air bleed to release any entrapped air and close again.
11. Maintain engine speed of 2,000 rpm for 3-5 minutes or until hot air comes from the heater.
12. Return to idle and verify hot air is still coming from the heater.
13. Set the heater temperature setting to 24? C (75? F) and allow the vehicle to idle for two minutes.
18. Shut the engine off and allow to cool.
19. After the engine has cooled, add coolant to the degas bottle to bring the level to the cold fill MAX mark.
procedure on how to bleed air out of coolant system on 97 saturn ls
how do i bleed my accord v6 2000 coolant system, its has air and the rev's gone up & down......
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.
To bleed the cooling system on a 1996 Olds Cutlass, locate the bleed valve, which is on the front of the engine above the water pump. After making sure the cooling system is not under pressure, open the valve by turning it counterclockwise. Fill the radiator with coolant until no air comes out the bleed valve, and a stream of coolant begins to flow from there instead. Tighten the valve and close the system to finish the job.
To bleed the coolant system on a 1998 VW Beetle, remove the top from the overflow tank. Run the car for 10 to 15 minutes to force any air out of the system, then check the coolant level. Add coolant as needed.
There is a bleed screw on the thermostat housing. Remove the screw with the engine loose. Ounc you have pure coolant and no air you can close off the bleed screw.

Start by taking the top off of the coolant overflow reservoir. To bleed the system, run the 1998 VW 2.0 Beetle about 10 minutes, then check the coolant level. Add coolant if needed, then replace the reservoir top.
what is the year make & modle of it??
Not necessary on this vehicle.
As you did not include engine or Year info I will give a general answer. Look on the top of the engine, most GM products with a bleed system have a small brass pipe thread plug in the top of a black or aluminum casting. This is the bleed point, loosen the plug or valve and add coolant to the system until it flows from the bleed, tighten up the bleed. Done. Repeat if needed.
Good luck haha..
