Pressure System
| 1 - MOUNTING BOLT |
| 2 - HOSE |
| 3 - HOSE |
| 4 - COOLANT RECOVER CONTAINER |
The pressure chamber keeps the coolant free of trapped air, provides a volume for expansion and contraction, and provides a convenient and safe method for checking and adjusting coolant level at atmospheric pressure. It also provides some reserve coolant to cover minor leaks, evaporation or boiling losses. The overflow chamber allows coolant recovery in case of an overheat.
