I've flushed the cooling system on a lot of cars. Ones i've owned, ones i've built. Is there a trick to the LS1. Tonight i had temp spikes and drops. low or no heat 240 degrees and back. Finally just let it cool to start fresh tomorrow. Car is a 2000 ws6. Always! always runs right below 210 always. At least until tonight. Is there an air bleeder i didn't see. Any help would be appreciated.

no, but you could try pumping the lines with your hands to increase to the removal of the air in the lines.

You have to fill the motor first.
you fill it thru the top hose on the water pump.

I think air is in cooling system, I like to disconnect the hose which goes to t-body when filling, I think this will allow air to purge

That would serve the same function as removing the radiator cap, as that line just dumps in right below the cap itself.

Our cars can be bastards when it comes to getting all the air out. You usually just have to let it heat up, fill it, fill it, fill it and fill it untill you are blue in the face (and red on the hands harharhar). You'll get to a point where you swear it's taken in 23 gallons, and it'll be just right.
