Recently purshased a 98 concours, I noticed that the temp gauge runs right past the half mark. The front of the temp needle actually barely touches the back of the half way mark. If I do any kinda or aggressive driving or prolonged idling the temp gauge goes to the next line past the half mark. It'll generally stay there until I start driving agian and then it'll eventually come down. Is this normal or does is it a thermostat problem. The temp never goes past line right after the halfway mark but it just hangs there too much for me. Whats it sound like guys-THanks in advance-Joey!!
