Line A: Ice starts to form (slush)
Line B: Temperature at which engine freezes and breaks
1. Safe range
2. Malfunction can arise (ice slush)
3. Coolant frozen
Cold characteristics of glycol:
- Example with 30% glycol by volume
- Ice slush starts to form at -18 °C.
- At -30 °C there is a risk of malfunction
- The engine cannot be damaged if there is at
least 30% glycol by volume
