There is a thermostat bypass hose that is metal and has a hex screw mounted atop it. Open this slowly with light pressure to not put serious torque or you will break it off. Then allow the system to vent until a steady stream of coolant emerges. Once the steady stream emerges, slowly and with as little pressure as possible tighten the hex screw DO NOT SNAP OFF THE HEAD, until coolant discontinues from the valve.
One way is to let the car idle with the reservoir cap off, called "burping" should get rid of most air pockets in the engine.
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......
No.
I would. Just remove radiator cap and start the engine and let it run for 30 minutes. As it runs, the stat will open and coolant will circulate pushing the air out. You will need to watch it and top off the coolant. After 30 minutes of cycling this will be done.
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.
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.
You have to use a radiator funnel kit from napa part # 77-4000 runs about $20. Chevy vans do not have a bleed screw.
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.
did u bleed the coolant system of air cuz that could be the reason
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.
