RADIATOR SERVICE
The radiator is mounted between the hydraulic oil
cooler and engine-cooling fan. The oil cooler is
mounted in front of the radiator and behind a remov-
able dust screen. The dust screen should be removed
and cleaned after each use. Hydraulic oil cooler service
is covered in Section 8.
Changing Coolant
1. Shut down the engine and remove the ignition
key. Allow the engine to cool completely.
2. Remove the radiator cap and open the drain pet-
cock located on the bottom of the radiator
(Figure 3D-6). Drain the coolant into a suitable
container.
NOTE:
It is illegal to dispose of most antifreeze in an
inappropriate manner. Always dispose of anti-
freeze according to local environment laws and
regulations. Contact local environment personnel
for information on disposal methods.
3. With the petcock open, flush the inside of the radi-
ator with fresh water.
4. Fill the radiator with a 50/50 mixture of good qual-
ity antifreeze and clean fresh water.
5. Install the radiator cap and start the engine follow-
ing the instructions in the Safety & Operation man-
ual.
6. The engine allows air to circulate through the radi-
ator, cooling the antifreeze/water mixture (cool-
ant). If the core becomes clogged with dust and
dirt, or the cooling fins are bent, the radiator will
not cool properly.

CAUTION
Never remove the radiator cap when the coolant is
hot. The engine must be shut down and cooled
before the radiator cap is removed. Very hot coolant
will be sprayed from the radiator if the cap is loos-
ened before the engine has cooled. Serious per-
sonal injury can occur.
CAUTION
Always use a mixture of antifreeze and fresh water
in the engine cooling system. Normally a 50/50 cool-
ant mixture will provide freeze protection to -37°F
(-38°C) and boil over protection in an efficient cool-
ing system.
