2005 actual operating temperature

Discussion in '2002 - 2005 Ford Thunderbird' started by hestech, Jul 31, 2017.

  1. Has anyone read out the actual operating temperature of the engine coolant with the gauge at half way point, where they all seem to sit, using the OBDII with a code reader? My car levels off at about 226 degrees F. Seems a bit high.

    I haven't checked the actual temperature in degrees but all the newer cars after 1996 all run in the 200's. They do that so as there is a complete burn of fuel and the cat's run cleaner. If you think it is too high call a Ford dealer and see what their service bulletins call for it to be.........

    Sourced a NOS 180F (77C) thermostat from Jaguar Racing Division. Was used on Jaguar British Saloon Racing S-Type cars. Currently researching which aluminum thermostat housing to use.
