Leave Cap off rad tank run 10mins any air should bubble out
Refill rad tank 2hrs later, try again 2 weeks later if you want and notice thermostats defective it may make more sence
It's up on the thermostat housing. Follow your upper rad hose to the thermostat housing.
The bleed screw is by the thermostat housing it looks like a brake bleed screw
Bleed valve is located on top of thermostat housing.
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 a brass fitting on the top of the thermostat housing.

the thermostat is located in the housing where the top radiator hose enters the engine. Note: there is also a brass screw on the top of the housing, this is to bleed the air from the cooling system when you replace the thermostat (or do other cooling system repairs)
There are no bleed valves on the engine, if that is what you mean.
I believe you want to drain the coolant, remove the top hose at the thermostat housing, remove the housing, replace the stat and gasket, reassemble fill with coolant and bleed the system.
Hi,If you are looking for the thermostat for the cooling system, it is located very close to the throttle body assembly. There are some pictures of the general area at the link I have provided. These pictures show where the bleed valves are located, and if you follow the radiator hose near the throttle body, you will find the thermostat housing. The thermostat is kind of a pain to change on these particular vehicles because of the tight space involved.Good Luck, Greg
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.
It should have a bleeder screw on top of the thermostat housing.
