change the thermostat ?

Hello,

Did the vehicle had overheating issue before you changed the thermostat?
If it did not have that issue and just started to overheat after the thermostat replacement, it is likely that the thermostat is defective and need to be replaced.

The thermostat should open at 195F for your vehicle.

Please let me know if you have any questions.

Thank you.
