Torque app says about 188*F temp in cruise. Unlocked cluster test #7 shows about 84*C in around town with OAT of ~35*C.

Well thankfully it was not stuck closed! And I just changed it maybe 15K miles ago when I did all the hoses, belts and tensioners. I'm getting a Behr thermostat unit this time

Sure hate to be in those 210*F temps but the open loop fuel economy sucks!

Just received a Wahler thermostat to replace the OEM that has been locked open for the past year. Expansion tank had a pin hole leak that dropped the coolant level enough to stick the thermostat open, but didn't get a chance to change it out. Hope to do this tomorrow.

Last week changed out the rear driver side window regulator (second time) and door actuator.

Tomorrow, need to remove the driver side head light and reconnect the adjustment plate so the high beam and low beams are aiming tin the same direction again.
