There is a bolt on top of the thermostat housing itself. using a very small metric socket open slightly to relive trapped air pressure in side of engine. This works on the 3.8l Ls models as far as i know.
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.
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.

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.
