A - Radiator Cap

1. CAUTION: Explosive release of fluids from pressurized cooling system can cause serious burns.

   Remove radiator cap only when engine is cold or when cool enough to touch with bare hands. Slowly loosen radiator cap to first stop to relieve pressure before removing completely.

   IMPORTANT: John Deere Liquid Coolant Conditioner does not protect against freezing. Coolant conditioner prevents rust, scale, and liner cavitation.

   NOTE: Check coolant every 500 hours or 6 months, or when replacing 1/3 or more of coolant. Add coolant conditioner as necessary.

   Remove radiator cap (A) and test coolant solution. Use one of the following kits to check coolant:

   • 3-Way Heavy Duty Coolant Test Kit (TY16175): Coolant test strips provide an effective method to check freeze point and additive levels of engine coolant. See your authorized dealer for 3-Way Heavy Duty Coolant Test Kit and follow instructions on kit.
   • COOLSCAN PLUS: For a more thorough evaluation of coolant, perform COOLSCAN PLUS analysis, where available. See your authorized dealer for information about COOLSCAN PLUS.
   
   

2. Add TY16004 John Deere Coolant Conditioner or equivalent non-chromate conditioner/rust inhibitor as necessary. Follow instructions on container for amount.
