Default coolant thermostat??

Just got my LS1 swap to start today.... I let the car idle for awhile and i filled up the radiator with Dex Coolant (org). The car got to 210 and above....the thermostat never opened up cause my upper and lower hoses werent even hot??? the Fan turns on... The motor only had about 40K on it... its an 2000 LS1 V8. Any suggestions??

Make sure you have everything connected. If your hoses arn't even warm then check your water pump. You may not even have proper flow through the block.
