Radiator Removal; Radiator Installation - Toro Groundsmaster 3500 30807 Service Manual

Radiator Removal

1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch.
2. Open and remove engine hood from the machine.
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 radiator/hy-
draulic fluid cooler to collect the coolant. The container
should have a 2 gal. (8 Ltr.) minimum capacity. Open
drain−cock valve, and completely drain the radiator.
4. Place a suitable container under the hydraulic filter
to collect the hydraulic fluid. The container should have
a 6 gal. (23 Ltr.) minimum capacity. Disconnect the hy-
draulic hose below the filter head or remove the hydraul-
ic filter element and drain the hydraulic system (Fig. 11).
5. Disconnect following hoses from the radiator/hy-
draulic fluid cooler:
A. Upper radiator hose to the water pump.
B. Lower radiator hose to the coolant inlet tube at
engine.
C. Coolant hose to the expansion tank.
D. Air hose to the air cleaner.
E. Hydraulic tube from top of hydraulic fluid cooler.
F. Hydraulic hose from bottom of hydraulic fluid
cooler.
6. Remove expansion tank from bracket on fan shroud.
7. Remove both fan shrouds from radiator assembly.
8. Remove flange head screws securing the top and
bottom of the radiator frame to the radiator. Remove four
carriage bolts and lock nuts securing the radiator to the
radiator frame.
9. Carefully remove radiator/hydraulic fluid cooler from
the radiator frame.
10.Plug any openings in the radiator/hydraulic fluid
cooler and hydraulic system to prevent contamination.
