Check Engine Coolant Properties

NOTE: Coolant replacement period is after three years or 3000 hours thereafter. It can be extended to five years or 4500 hours thereafter when coolant is checked annually and replaced by COOL-GARD™ II.

Ask your John Deere dealer to check engine coolant properties. (Refer to Heavy Duty Diesel Engine Coolant, in Fuel, Lubricants, and Coolant section of this manual.)
