15Section 5 — Maintenance & adjuStMentS
If the overflow reservoir is empty, the radiator cap should be
removed and the coolant level in the radiator checked before
adding coolant to the reservoir. If necessary, first refill the system
through the radiator filler neck as follows:
WARNING: It is dangerous to remove the radiator
cap when the system is hot. Allow the system to cool
before removing the radiator cap.
1. Turn the radiator cap counterclockwise to the first stop to
release any pressure.
2. Push downward on the cap and turn counter-clockwise
until the cap stops then lift cap off.
3. Slowly pour coolant into the filler neck until the level
reaches the bottom of the filler neck overflow flange.
4. Wait a few minutes to allow as much air as possible to
escape through the filler neck, then reinstall the radiator
cap.
5. Fill the overflow reservoir to the “FULL” mark.
6. Start the engine and allow it to run for a short period. Stop
the engine.
7. Recheck the coolant level in the overflow reservoir and
refill as needed. Reinstall the reservoir cap.
8. If engine over-temp light comes on or stays on after filling
radiator and reservoir, see your Cub Cadet service dealer to
bleed air from system.
Changing the Engine Coolant
The engine coolant should be drained and replaced with new
coolant solution every 2 years or 500 hours. See your Cub Cadet
service dealer to have the engine coolant changed.
Cooling System Hoses
Check the cooling system hoses and water pump belt for any
cracks or deterioration after every 100 hours of operation. Check
for loose hose connections. Replace any damaged hoses and
tighten any loose connections. Replace a worn or damaged
water pump belt.
Transfer Case Oil
WARNING: The fluid for your transmission has
been specially formulated to ensure the safe and
proper operation of your vehicle. When changing
the transmission fluid replace it with 80W-90 Shell
Dentax Low Foam Oil. Failure to use 80W-90 Shell
Dentax Low Foam Oil may result in a failure of the
drive system which could result in property damage
or personal injury. DO NOT substitute.
Check the transfer case oil every 100 hours or yearly and change
it at the first 50 hours and then again at 500 hours.
1. Park vehicle on level surface, place shift lever in Neutral,
and apply parking brake.
2. Allow transmission sufficient time to cool before
attempting any maintenance or repairs.
3. Raise and secure cargo box, if manual lift.
4. Access drain plug through slot on underside of machine
and remove plug. See Fig. 6-3.
5. Allow oil to drain into a suitable container.
6. Check O-ring on drain plug and replace if missing or in
poor condition.
7. Add approximately 64 oz of 80W-90 Shell Dentax Low
Foam Oil through the fill/level plug port. When oil begins
coming out of opening, the transmission is full.
8. Install and tighten fill/level plug.
9. Lower and latch cargo box.
