Cooling system
Coolant resistance to cold
The following example shows coolant properties
with 30 percent by volume of antifreeze and cor-
rosion inhibitor:
• Ice slush starts to form at -16°C (3°F).
• At -30°C (-22°F), there is a risk of cooling
system malfunction.
• There is no risk of damage by freezing with a
minimum antifreeze and corrosion inhibitor
content of 35 percent by volume.
The chart depicts coolant properties at different
percents of antifreeze and corrosion inhibitor
concentration by volume.
Curve A: Ice formation starts (ice slush)
Curve B: Damage by freezing occurs
Area 1: Safe area
Area 2: Malfunctions may occur (ice
slush)
Area 3: Risk of damage by freezing
