Who can tell me how to properly bleed the cooling system on a 95 lt1??

 

I'm not 100% sure on that engine, but there's usually a bleed screw on or around the thermostat housing. Get the engine up to normal operating temp. Then you undo the screw until coolant leaks out. If there's any air in the system, it'll bubble out. When the coolant comes in a solid stream, you know the air is all bled out.

Usually, it's a good idea to do this several times. Depending on the location of the bleed screw, it might be a good idea to park facing uphill or on ramps/stands. You want the screw to be the highest point in the cooling system, so the air can properly rize to the bleed point.
