If winterfronts are used, they should never totally close
off the grill frontal area. Approximately 25% area in the
center of the grill should remain open at all times. At
no time should the air blockage device be applied
directly to the radiator core.
Radiator Shutters
If equipped with a thermostatically controlled radiator
shutter system, this system should be regulated in
such a way that the shutters are completely open by
the time the coolant reaches 93
°
C (200
°
F) to prevent
excessive intake manifold temperatures. Manually
controlled systems are not recommended.
If air-to-air aftercooling is used, the shutters must be
completely open by the time the intake manifold air
temperature reaches the maximum allowable
temperature out of the charge air cooler.
For more information, see your John Deere dealer.
