Drove 30 miles @ 70 mph on a cool morning last week, then drove at 30 mph for about 10 minutes thru town. Stopped to let my wife out to check on an appointment. I left the engine running and after several minutes I heard the radiator fan come on. In 6 years of driving this car I don't think I have ever heard the fan come on, so it caught my attention and I immediately checked the coolant level. (No ScanGuage) Level was normal and I haven't heard it since. If it had been mid-day with the temp in the 90's, I wouldn't have been concerned, but since overheating is such a critical factor in these little guys, I was concerned. Anyone else ever notice their fan come on in cool conditions? I guess my next investment will be a scanguage!
