03 GT Running Too Hot
I've got an 03 GT with 45k on the odometer. Last year I ignorantly topped off the coolant by simply adding about 1-16 ounces to the reservoir under the seat. After doing so, I noticed that at around 4000-5000 RPM at lower speeds for extended periods of time (few miles) the needle on the temp gauge gets closer to the red mark. I already checked on the fan operation and they're working fine. So I decided to flush the cooling system as per the official BMW Service manual. I added about 3 ounces of water wetter for added measure. A friend of mine who is a BMW mechanic told me that I need to stop looking at the gauge and only worry if the red light on the panel comes on. He also said that if I drive it long enough, the bubbles will work themselves out (if there are any in the system.)
Tonight during a mild 50 mile ride in 75 degree weather, the same thing happened. At 80 mph on the highway, the needle was even under the halfway mark. Again, at 4-5 thousand RPM at lower speeds, the needle climbed up again closer to the red line but not touching the line. I pulled into a Sheetz and let it run for about 10 minutes. The fans were working but the needle jumped to the red line, but again, no panel light.
Has anyone else ever had a similar problem?
Thanks in advance
