I've got a coolant leak in my 2003 XC70, and the odd thing about it, at least to me, is that the leak doesn't appear while the car is running and at full temperature/pressure. The leak appears about 2.5 hours after the car is parked. It's dripping on the passenger's side.
For example, I drove the car for 20 minutes today mostly at highway speeds. Parked 10-15 minutes. No leak. Drove another 20 minutes on highway and stopped at a pharmacy for about 10 minutes. Checked for leaks. No leak. Drove home. 2.5 hours after the car was parked, it's dripping, leaving a small wet spot on the driveway.
Then once the car is pretty completely cooled down (four hours), the leak stops.
Any ideas what would cause this kind of leak?
