[C320-list] Coolant in fresh water

[John Morrison]

Sounds like you might have. I’d take it to a rad shop to have it checked out. Had you noticed a drop in coolant level during normal running?

One of the clamps seals the rubber cup onto the tube itself to seal the freshwater system.  The second large clamp seals the tube assembly onto the heat exchanger tank.  The 2 clamps effectively seal the 2 different systems from each other .... the freshwater.....and the system with coolant in it.  The heat exchanger tube itself is not sealed off from the tank until the front and rear rubber caps are installed and the clamps tightened.
