Hi, My wife's 96 Accord is at about 200,000 miles. Still runs fine. I noticed thatg on a hot day, after a drive, when the car is shut off, the radiator fan will still run for quite a while, sometimes at least another 15 or 20 minutes. Should I be concerned about this? It does NOT seem to be running the least bit hot. It is right in the middle zone where it always has run. Any ideas?
