NOTE:
Antifreeze is essential in any climate. It broadens the operating temperature range by lowering the coolant freezing point
and by raising its boiling point. Antifreeze also contains rust inhibitors and other additives to prolong engine life.
IMPORTANT:
If antifreeze strength is not adequate, do
NOT
drain the cooling system to protect against freezing. The system may not
drain completely, and damage from freezing could still result.
