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.
intake gasket, leaking radiator and radiator cap, leaking heater core,, air in the sytem that needs to be bleed by the bleed screws,,,but most of all on all these cars with the 3.8 or 3.4 are bad about intake gaskets,,hope this helps
there should be a air valve on the engine that you can bleed the bubbles out of the cooling system.
my o6 chevy impala is lighting up on the dash that the engine is hot but the gauge is saying its cold what is wrong and how can i fix it?
It is a brass fitting on the top of the thermostat housing.
Watch how you take them off and put them back on the same way. Then you have to bleed them since there drum brakes
there should be a bleed valve towards the bottom of the rad. It will look like a " T : .
There is a small brass valve on the top of the thermostat housing where it attaches to the top radiator hose. Loosen it and then fill the radiator until coolant comes out of the valve and then quickly close it. This is only for an impala with the 3.8 liter engine though I believe there are two valves on the 3.4.
You have to use a radiator funnel kit from napa part # 77-4000 runs about $20. Chevy vans do not have a bleed screw.
How do you bleed air from radiator of a 2000 range rover?
next to the radiator cap on top of the radiator
there is a pee-cock "valve"on the bottom of your radiater. If you are trying to bleed the air from the system while filling the radiator. Where the top radiator hose connects to the engine just to the left of the intake there is a bleed valve. Take a 12mm socket and loosen this a couple of turns. When coolant starts to run out, tighten this valve (do not overtighten they break easily)
It doesn't have a bleed valve for the power steering.
