i'm leaving in about 3 weeks to go to jersey!! i have a 98 taurus with 104,000 miles on it and its about a 21 hour/1300 mile trip. i was planning on leaving baton rouge anywhere between 10 am and 2pm and driving non-stop to jersey. i will have 2 other people with me and we will be driving in shifts. the main thing on my mind today was rest for my car. we will be stopping periodically for food, gas, stretching, and sightseeing, but not sleeping. i was wondering if i need to stop at some point and let my car completely cool down during the 21 hour drive.
