Please help went to dyno and car overheats in 2 minutes
For some reason my car overheats in just a few minutes at idle. Just reassembled the engine. Ls6. New water pump. Spun good. Removed thermostat-looks good. If it matters the heater plugs are capped. radiator was topped with water. Aftermarket radiator, I plumbed the lower water pump hole, the one that has the thermostat in it into the lower radiator hole and the upper to the upper., correct.... And the coolant cross over line is plumbed into a bung on the radiator. Cometic head gaskets, there is no front labeled on them. I pulled one of the heads and looks right. There is a larger water passage on the drivers side rear and I matched that to the gasket that had a larger water jacket on one side. I'm stumped, I haven't pulled the drivers head yet, if that gasket were flipped would both sides get hot. O ya, water temp gauge on both heads showed HOT. Ideas please, trying to make a trip this weekend and want to take the car.

Pulled the other head gasket and it was reversed. But when re-assembled it still ran to hot. The radiater was not getting collant. Removed the thermostat and it seems to hold at 200 at a high idle. what are the temps I should be looking for? At what temp should I shut it down, idle at? And why is my new thermostat not opening.

For future users that may search this, problem was that I capped the heater hose outputs because I'm not running a heater. The LS thermostats get their hot water from these lines and then will open. So If you cap them don't, run a hose and connect them together.
