coolant into a clean container.
2. Flush the inside of the radiator (3) with clean water.
NOTE
Always mix anti-freeze with the cooling water.

radiator.
Open access door at bottom of radiator to allow trash
to fall out during cleaning.
REMOVAL (See Figure 3D-2)
1. Loosen wing nuts holding oil cooler in place and
tilt oil cooler out of the way.
2. Remove hardware securing fan shroud to radiator
and move shroud back over fan.
3 Open drain cock (1), remove radiator cap (2) and
