E34 M5 - Where is the coolant overflow vent
Found some coolant under the car a few hours after parking in the garage. Thinking it is a leak from a hose, I topped up the coolant tank, drove next weekend and after parking found the same amount of coolant under the car. After lifting the car up, the source is from the two drip vents on each side of the transmission tunnel, next to the transmission. Is this overflow from too much coolant or do I have another problem? The car runs fine and holds temperature fine. Thanks.
