i'm also experiencing overheating before. previous owner removed the t-stat. i put in a 82C t-stat. overheating gone. but then after a few months, temp rises esp. on bumper-to-bumper traffic and WOTs on highways. what i do is release the hood lock on traffic. it's effective. on highway runs, i just let off the throttle and maintain my speed at about 45 mph to cool it down. maybe i need hood louvers.
