Hi everyone. I need your opinion about something. I know there have been numerous threads in the past about engine temperatures, but this one might be a little different. I have a '71 GTO with the factory 400 motor and drivetrain. TH400 trans and 3.55 posi. I'm running a 180 degree thermostat, have a shroud, I think I have the divider plate in the waterpump correct, a spring in the lower radiator hose, new fan belt and a new Cold Case radiator. When I initially start the car and begin driving it, it seems to take some time and several miles for it to reach operating temperature. It gradually will reach 180 degrees, stay a while and then settle in at about 195 degrees. During normal driving, it will stay at 195, but eventually will creep to 210 degrees. It will stay there and then back off some to maybe 200 degrees. I can't tell you why it does this. No hills. No excessive speed. I've never seen it go above 210 degrees no matter what I was doing. This includes driving, idling and stuck in a little traffic. I'm not completely happy with the 210 degrees but I don't know if it's necessarily a bad thing. What are your thoughts on this??? I've read where some engines never get hotter then 170-180, so my 210 certainly makes me think about this. Many thanks, Nicholas.
