Operating in Warm Temperature Climates
John Deere engines are designed to operate using glycol base engine coolants.
Always use a recommended glycol base engine coolant, even when operating in geographical areas where freeze protection is not required.
IMPORTANT:
Water may be used as coolant in emergency situations only.
Foaming, hot surface aluminum and iron corrosion, scaling, and cavitation will occur when water is used as the coolant, even when coolant conditioners are added.
Drain cooling system and refill with recommended glycol base engine coolant as soon as possible.
