I checked out an 03 with 150k on the odometer, tall and long, exactly what i am looking for. The van was really clean but i noticed one issue. There appears to be a very small amount of coolant seaping from the passenger side rear of the head, directly under the exhaust port. I am almost sure it was coolant due to the green tint. It was not enough to even drip, just discolor the area. I searched the forum here but could not find this. Any ideas?
