My 3rd gen 4Runner has always ran between 185 - 195 degrees since I’ve owned it for the last 8 years. Last week I had a new timing belt, water pump, and thermostat installed. On the drive home after picking up my car from the shop I noticed on the OBD scanner it was running 195 - 205 degrees. Same for the drive to and from work the next day.
A quick search through these forums and I found that the FSM Manuel says for the jiggle valve to the positioned at the 6 o’clock position and that most shops position it 12 o’clock which in return makes the motor run 10-20 degrees hotter.
Today I pulled the thermostat and lo and behold it was positioned at 12 o’clock. After a quick adjustment I now am back to running the 185-195 degree temps.
