My 1998 SVT Cobra has a stock 4.6L with 59,000 miles on it. It runs perfectly in normal conditions. I just got home from Virginia Int. Raceway and she ran hot while doing hard laps. No problem in the morning, but as the afternoon warmed up to 90 degrees, she started running hot. My new AutoGauge registered around 245. Coolant and other fluids were fine. No apparent problems with radiator or air flow. Any solutions to keep the girl on the track during hot days?
