But it's not losing coolant so I'm not sure about that.....additionally, during normal driving it gets to about 222 and then eventually drops down to 215.....during a pull it gets to 233 and then drops again when I'm done......I'm thinking the coolant temperature sensor needs replacement and I have one coming on Saturday. If I installed a 160° thermostat then wouldn't it be open all the time? Also, this just started yesterday and has been in the same configuration throught the hot Texas heat during the summer and the dash gauge never exceeds 200° but the fan goes to high speed above 212°
