"An engine when warmed up is going to operate at what ever temp it wants to run at regardless of what thermostat is installed."?
What temperature will it run at with a :
160 degree thermostat
175 degree thermostat
90 degree thermostat
A more interesting question might be what temperature will it run at with no thermostat when:
- idling at 0 degree external temperature
- idling at 30 degree external temperature
- idling at 70 degree external temperature
- idling at 90 degree external temperature
or
- driving (less than 25 MPH or more than 55 MPH) at 0 degree external temperature
- driving (less than 25 MPH or more than 55 MPH) at 30 degree external temperature
- driving (less than 25 MPH or more than 55 MPH) at 70 degree external temperature
- driving (less than 25 MPH or more than 55 MPH) at 90 degree external temperature
Answer: "at what ever temp it wants to run at"?
Are the answers good reasons for using a thermostat, and running the engine at the GM recommended temperature?
