arrow on filter body should point away from tank. Remove old filter and
install new filter. Replace two spring clamps. Remove clamp used between
filter and tank. Check for leaks.
John Deere 1025R, 1023E Cooling System
Check Coolant Level
Raise hood. Check coolant level in the recovery tank. If engine is at
operating temperature, coolant level is at the FULL HOT line. If engine
is cold, coolant level is at the FULL COLD line on the recovery tank. To
add coolant, remove recovery tank cap. Add recommended coolant if
needed. Install recovery tank cap. Lower hood.
Drain and Flush Cooling System
Shut off JD 1025R, 1023E 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. Allow engine to cool. Raise hood.
Slowly open radiator cap to the first stop to release all pressure.
Close radiator cap tightly. Position a pan under the radiator drain
tube. Open the drain plug and allow the coolant to drain from the
system. Remove the drain plug from the engine block and finish draining
coolant. When coolant drains from the recovery tank, remove the radiator
cap. Close radiator drain plug and install drain plug. Fill the cooling
system with clean water. Run engine until water passes through the
thermostat to stir up possible rust or sediment.
Stop engine immediately and drain water from the system before rust and
sediment settles. Fill cooling system with clean water and John Deere
Cooling System Cleaner, or Cooling System Quick Flush or an equivalent.
Follow directions on the container. After cleaning the system, drain
cleaner and fill the system with clean water to flush the system. Start
and run engine until water passes through the thermostat. Stop engine,
and drain flushing water from the system. Close all drain orifices and
fill cooling system to specification. Cooling system capacity - 3.7 L
(3.9 qt). Install radiator cap and run engine until it reaches operating
temperature. Stop engine and check coolant level. Add coolant if
necessary. Lower hood.
JD 1025R, 1023E - Fill Cooling System
Allow radiator to cool. Fill cooling system. Install and tighten

John Deere 1025R, 1023E - Alternator belt
Check Belt Tension
Park machine safely. Allow engine to cool. Raise hood. Remove left side
panel. Check tension by using the belt tension gauge to apply pressure
to the belt midway between pulleys at location. Belt should deflect 9 mm
(3/8 in) at 75 lb (334 N). Adjust belt tension if not within
specifications. Belt Tension Force - 75 lb (334 N). Belt Tension Inward
Pressure - 9 mm (3/8 in)
Adjust Belt Tension

belt tension. Adjust as necessary. Install left side panel. Lower hood.
John Deere 1025R, 1023E - Start the Engine
Move the transmission range-shift lever to the N position. Confirm the
PTO/RIO switch is in the disengaged/off position. Lower any implements
to the ground. Set the hand throttle to the 1/2-3/4 position. Turn the
ignition key switch to the ON position and verify that all indicator
lights and gauges are working: All indicator lights illuminate. All
gauges do a full sweep and return to normal. Avoid damage to the
starter! Operating the starter for more than 20 seconds at a time
results in damage to the starter.
If the engine does not start, wait two minutes before trying again. Turn
key switch to the START position. Release the key when the engine
starts. Check the indicator lights: The oil pressure light turns off
after 5 seconds of the engine running. If the light it does not turn
off, the engine oil pressure is too low. Stop the engine and check for
the cause. The alternator/battery charging light turns off after 10
seconds of the engine running. If it does not turn off, set the engine
speed at full throttle. Run the engine at the 1/2 fast position for 1
minute without load.
Daily Startup Procedure
Test safety systems. Perform safety interlock system checkout procedure.
Check engine oil level. Check / drain water separator. Check
transmission fluid level. Check coolant level. Clean air intake screen
and radiator screen. Check air filter elements and dust valve. Check
wheel bolt torques. Check tire pressure. Check fuel level.
