Your Jeep needs HOAT coolant. Mixing other types of coolant with it will cause chemical reactions inside your cooling system, which will ultimately destroy the entire system.

, and this video helps.
now that you've contaminated the system, you need to thoroughly flush it with distilled water, and start over using this procedure
make sure the thermostat has a bleed hole, and will correctly bleed air from the system. also, the jeep should run at 195-210°F, 180 is actually too cold.
