You should still go into closed loop with that thermostat. To check for open/closed loop, run the car and ground the ALDL,like when you check for trouble codes. One flash per second is closed loop, while 2 per second is open loop. Keep in mind that if you sit at a light for a while, or idle, you may go into open loop.
