Where is radiator bleed valve on a car.?

A lot of new GMs bleed valves are on top of the thermostat housing (high spot, air gathers there. You just turn it 720 degrees ort so when the car is up to temp and it will bleed out the air.

The drain cock is on the bottom right side tank i think, but I would just remove the bottom hose.

open the cap on the recovery tank get under neath the car and look for a pet cock valve on the left side (if your in front of car facing the engine) there is a hole in the plastic shield under the radiator and the valve should be right there

make sure the engine isnt hot at the time or you will invent a few new curse words as well as use a few old favorites

I`m not familiar with that car , I would guess at the bottom of the radiator....like most car , unless that this one does not have one , and in that case , remove the lower radiator hose.
