Removal (Fig. 8)
1. Park machine on a level surface, lower cutting unit
(or implement), stop engine, engage parking brake and
remove key from the ignition switch.
2. Open hood and secure it in the raised position.
CAUTION
Do not open radiator cap or drain coolant if the
radiator or engine is hot. Pressurized, hot cool-
ant can escape and cause burns. Ethylene–gly-
col antifreeze is poisonous. Dispose of coolant
properly or store it in a properly labeled contain-
er away from children and pets.
3. Place a suitable container under the left corner of the
radiator to collect the coolant. Remove plug (item 12)
(hex socket head) from bottom of the radiator and com-
pletely drain the radiator.
4. Disconnect following hoses from the radiator:
A. Upper radiator hose to the water pump.
B. Lower radiator hose to the engine block.
C. Coolant hose to the expansion tank.
D. Air inlet hose to the air cleaner assembly.
5. Remove four (4) screws and flat washers that secure
fan shroud to radiator. Carefully position fan shroud
away from radiator taking care to not damage fan.
6. Remove four (4) cap screws and flange nuts secur-
ing the radiator to the radiator frame.
7. Carefully pull radiator from the radiator frame and
machine.
8. Plug radiator and hose openings to prevent contami-
nation.
Installation (Fig. 8)
1. Remove all plugs placed in radiator and coolant hose
openings during the removal procedure.
2. Carefully position radiator to the radiator frame.
3. Secure radiator to the radiator frame with four (4) cap
screws and flange nuts.
4. Carefully position fan shroud to radiator taking care
to not damage fan. Secure fan shroud to the radiator
with four (4) screws and flat washers.
5. Make sure that equal clearance exists at all points
between fan shroud and fan.
A. To move fan shroud left or right, adjust location of
radiator in radiator frame.
B. To move fan shroud up or down, adjust location of
shroud on radiator.
6. Connect following hoses to the radiator:
A. Upper radiator hose to the water pump.
B. Lower radiator hose to the engine block.
C. Coolant hose to the expansion tank.
D. Air inlet hose to the air cleaner assembly.
7. Apply thread sealant to threads of radiator plug (item
12). Install plug into radiator opening.
8. Check that no gaps exist between radiator, radiator
frame and machine frame. If necessary, seal gaps with
silicone caulk.
9. Fill radiator with coolant. Make sure that expansion
tank coolant level is correct.
10.Close and latch hood.
