Liquid Coolant Conditioner

RG4690-UN-14DEC88

John Deere Liquid Coolant Conditioner is recommended for wet-sleeve diesel engines not having a coolant filter option. See your John Deere dealer. Other conditioners may be used if they contain non-chromate inhibitors.

CAUTION: Coolant conditioner contains alkali. Avoid contact with eyes. Avoid prolonged or repeated contact with skin. Do not take internally. In case of contact, immediately wash skin with soap and water. For eyes, flush with large amounts of water for at least 15 minutes. Call physician. Keep out of reach of children.

Do not remove reservoir cap or drain coolant until coolant is cold. Always loosen reservoir cap slowly to relieve any excess pressure.

IMPORTANT: Do not use liquid conditioner if engine is equipped with a John Deere Coolant Filter Conditioner, since the correct inhibitors are already contained inside the filter. If both are used, a gel-type deposit is created which could inhibit heat transfer and block coolant flow. John Deere Liquid Coolant Conditioner does not protect against freezing.

Add 30 ml of John Deere Liquid Coolant Conditioner for every liter of coolant added (1 fluid ounce per quart). When servicing cooling system at 2000 hours, only 1/2 of the original charge is required.
