COOLANT LEAK

[BBBAD94ZR1]

Anyone ever encounter a leak by the collant resivor on the right side? I seem to have coolant around that area after the car cools down. What is the small black Pvc hose by the tank? What purpose does it serve? It comes off the plenium. Im going to take it apart tonight.
Thanks

Found out why, previous owner had the tank over filled.

Small plastic hose = vacuum supply hose for the secondary port system from the vacuum pump above the coolant overflow tank.:thumbsup:
