Removal (Fig. 8)
1. Park machine on a level surface, lower cutting
decks, stop engine, apply parking brake and remove
key from the ignition switch.
2. Raise and support the hood.
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--glycol antifreeze is poisonous. Dis-
poseof coolantproperly, orstoreit in aproperly
labeled container away from children and pets.
3. Drain coolant from radiator.
A. Slowly remove radiator cap from the radiator .
B. Place drain pan below the radiator draincock lo-
cated on the bottom of the radiator. Make sure that
drainpanislargeenoughtoholdcoolingsystemcon-
tents (10 U.S. quarts (9.5 liters)).
C. Loosen radiator draincock (threaded in) and al-
low coolant to drain from radiator.
4. Remove screen from machine.
5. Disconnect radiator hoses (upper and lower) from
the radiator .
6. Loosen hose clamp and remove overflow hosefrom
radiator fill opening.
7. Remove two (2) flangehead screws and flange nuts
that secure coolant reservoir and brackets to fan
shroud. Carefully position reservoir and brackets away
from the fan shroud.
8. Remove five(5) flange headscrews and flange nuts
that secure air intake screen (item 37) to machine. Re-
move screen and foam seal (item 42). Locate and re-
trieve five (5) spacers (item 43).
9. Removeflangeheadscrewsandflangenutsthatse-
cure fan shroud and radiator to radiator frame. Position
fan shroud away from the radiator.
10.Carefully pull radiator assembly from the machine.
Plug radiator and hose openings to prevent contamina-
tion.
11.Inspect all foam seals placed between radiator, fan
shroud and radiator frame. Replace damaged foam
seals.
Installation (Fig. 8)
1. Remove plugs placed inradiator and hose openings
during the removal procedure.
2. Carefully position radiator assembly to the radiator
support. Position fan shroud to the radiator.
3. Securefanshroudandradiatortoradiatorframewith
removed flange head screws and flange nuts. Make
sure that at least 0.250” (6.4 mm) clearance exists at all
points between shroud opening and fan.
4. Position coolant reservoir and brackets to the fan
shroud. Secure reservoir to fan shroud and radiator
frame with two (2) flange head screws and flange nuts.
5. Place spacers (item 43)intoholes infoam seal(item
42). Position foam seal and air intake screen (item 37)
to radiator frame. Secure intake screen to machinewith
five (5) flange head screws and flange nuts.
6. Connect upper and lower radiator hoses to radiator
and secure with clamps.
7. Connect overflow hose to radiator fill opening and
secure with hose clamp.
8. Makesureradiatordraincockisclosed(threadedout
fully).
9. To allow air to escape during radiator filling, remove
pipe plug (item 8) from top of radiator . Fill radiator with
coolant. Makesuretoinstallplug onceallairisbledfrom
radiator.
10.After radiator has been properly filled with coolant,
install radiator cap.
11.Lower and secure hood.
