I don't think there's a big necessity for a second cooling system for high speed chases. How long are typical chases and what is the typical speed? None of the cars I've ever driven had any trouble running at 80MPH for 4 hours. People regularly go 100+MPH on the Autobahn; granted it's not in cop cars which are driven every day.

According to the Pursuits data, a majority of pursuits were short both in time (57% lasted 3 minutes or less) and distance (66% covered a distance of 3 miles or less). Despite their brevity, nearly half (45%) of police vehicle pursuits reached speeds of greater than 70 miles per hour, and nearly a quarter (23%) exceeded 90 miles per hour.
