CHECK COOLANT IN RADIATOR
CAUTION: Explosive release of fluids from
pressurized cooling system can cause serious
burns.
Only remove filler cap when engine is cold or
when cool enough to touch with bare hands.
Slowly loosen 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.
