    Normal behavior of coolant temperature

    So when it's really hot or I'm on the track, I turn on the exact coolant temp in the hidden menu.

    I've noticed when it's really hot the coolant temp can dip as low as 85 degrees. I thought these cars run at 95 pretty much all the time.

    My cooling system is all OEM with about 15k on it with a Stewart water pump.

    I'm assuming this is relatively normal.

    From this thread, it seems like the cooling system works harder when under load, often dipping the coolant temp down into the 80s. Someone else can chime in.

    Yes, I have noticed too that when you pull hard on it, the coolant temp drops down considerably. It is apparently designed for improved performance. I think we have a different thread that addresses that.

    Yea I know when you floor it it spins the water pump faster, so that makes sense. But when cruising on the freeway at 70, it's not working hard, other than its just hot outside.

    I'm probably making a big deal about nothing.

    Our temp gauges show a very wide range of temperatures in the middle position. I think it's something like the exact middle position being 75-110 degrees C. I have a corrected temp gauge, so as soon as the temp drops, my gauge will reflect that. When you push your car hard and you have factory gauge coding, your needle will not move at all to reflect the temp change. That is why you'll notice a discrepancy between your gauge and what the OBC says.

    If you get PA Soft, you can correct your temp gauge to show actual temp, which I highly recommend.

    Yea I'm well aware of the factory gauge, that's why I use the hidden menu option.

    Everybody says the cars run right at 95 all the time, so I got curious when it dips into the 80s for extended periods of time (10-30 minutes).

    ^ that's more weird, 10-30 minutes? Mine never does that.

    Yeah it does that on especially hot days when the fan is always cooling at a higher rate. If you sit in traffic for extended periods, it may do that. I noticed sometimes I'll be sitting in traffic and it'll just be sitting there a little below halfway. It always goes down when I do a hard acceleration.

    I wouldn't worry about it dipping into the 80s.

    I have noticed after the coolant gauge temp mod for the gauge to drop as well after getting on it.

    Much better then the factory buffer zone.

    Hidden menu coolant temp? How is this brought up?
