CAUTION: Explosive release of fluids from
pressurized cooling system can cause serious
burns.
Shut off engine. Only remove filler cap when
cool enough to touch with bare hands. Slowly
loosen cap to first stop to relieve pressure
before removing completely.
NOTE: When John Deere COOL-GARD is used, the drain
interval is 3000 hours or 36 months. The drain
interval may be extended to 5000 hours or 60
months of operation, provided that the coolant
is tested annually AND additives are
replenished, as needed, by adding a
supplemental coolant additive (SCA).
If COOL-GARD is not used, the flushing interval is
2000 hours or 24 months of operation.
Drain old coolant, flush the entire cooling system, test
thermostats, and fill with recommended clean coolant per
the following procedure.
1. Pressure test entire cooling system and pressure cap if
not previously done. (See PRESSURE TESTING
COOLING SYSTEM, in the Lubrication and
Maintenance/500 Hour/12 Month Section.)
2. Slowly open the engine cooling system filler cap or
radiator cap (A) to relieve pressure and allow coolant
to drain faster.
