Engine Cooling System
The cooling system can become a corrosion nightmare if not maintained correctly. Coolant is propelled around the cooling system at high velocity (usually 45,000–60,000 L/hr), there are some extremely high temperatures involved (3,000°C in the combustion chamber) and various metallic components. In effect, the cooling system can virtually become a giant battery, resulting in corrosion and, ultimately, engine failure.
Controlling the coolant pH is vital. Whether you face a simple coolant leak from a corroded radiator, or a more expensive engine rebuild because of liner pitting and corrosion, the result is the same: engine malfunction which equates to time and money wasted on repairs and downtime.
Coolant is not a ‘fit and forgets’ the item. It needs to be maintained, tested, inspected regularly, and periodically replaced. Dosing instructions need to be rigorously followed to ensure full system protection.
