1991 R129 500 SL Antifreeze Leak
Folks,
I have a 91 R129 w 50K miles. Recently I have a wierd Antifreeze leak. It drips behind the RF Passenger side tire. I have pressure tested the system and I hold pressure without an issue. The problem only occurs after the car is driven 5-10 miles. The puddles is about 4 inches in diameter.
No interior leaks, no visible signs around the engine that I can see with the plastic shield removed.
Any ideas?

the system ( expansion tank and radiator) has plastic sections and junctions that with time degrade and leak. Look for internal junctions.
