Tech Tip

·        Diesel engine cooling systems require year-round protection with a heavy-duty diesel engine coolant.  Running with water alone will rapidly lead to cooling system and engine problems

·        Drain the initial fill of coolant, flush the cooling system, and refill with new coolant after the first 2 years or 2,000 hours of operation. Follow guidelines below for subsequent testing and drain intervals

·        Check cooling system solution every 600 hours or 12 months, whichever occurs first. Test with John Deere Coolant Test Kit or CoolScan Analysis

·        John Deere Cool-Gard II, pre-diluted or concentrate, has a 6-year or 6,000-hour formulation. The life of the solution is subject to conditioner level testing every 600 hours or 12 months. Add John Deere Liquid Coolant Conditioner, as indicated by the test kit, to maintain the proper solution. If the coolant is not tested annually, add the appropriate amount (for system size) of coolant conditioner annually, and drain after 3 years or 3,000 hours

Wear Characteristics and Maintenance Tips: Cooling System

Regular cooling system maintenance is essential to maintaining engine uptime. Coolants wear out and require maintenance just as lubricants do. Maintaining the proper coolant chemistry protects against liner cavitation, corrosion, gelling, and deposits, while providing winter freeze protection.
