Diesel Coolant Extender

Diesel Coolant Extender is designed to maximize coolant life between drain intervals by replenishing coolant inhibitors that guard against rust and corrosion. The advantage of using an extender is that it boosts nitrite levels for protection against liner pitting caused by cavitation.
 
Performance Features & Benefits:
  • Extends coolant in-field service life up to 960,000 km (600,000 miles), 12,000 hours or 6 years
  • Replenishes corrosion inhibitors
  • Provides nitrite boost for protection against liner pitting
  • Specifically for use in HD Diesel EXL Extended Life Antifreeze/Coolant
  • Phosphate Free
APPLICATION: Use only with extended life coolants meeting the performance requirements of ASTM D6210. The coolant extender should be added at 480,000 km or 6,000 hours of operation, whichever occurs first.
Note: Do not use for initial fill or as a coolant top-off. Not for treatment of traditional type coolants.
