Draining The Cooling System; Filling The Cooling System - Cushman HAULSTER 898487 Parts And Maintenance Manual

ALWAYS keep the screen, radiator and oil cooler fins
clean.
NOTE: Clean the radiator and oil cooler fins with com-
pressed air. If water is used to clean the radiator or
oil cooler use compressed air to blow ALL the water
from the radiator or oil cooler fins. Water left
between the fins will collect dirt and clog the radia-
tor.
Keep the proper amount of coolant in the cooling
system.
Check coolant level in radiator and reservoir bottle. The
coolant should be up to the filler port of the radiator, and
between the FULL and LOW lines in the reservoir bottle.
Level should not be higher than the FULL line.
1. Radiator
NOTE: If the coolant level is low, check for leaks and
repair as necessary. If additional coolant is required,
a 50/50 mixture of a good grade of ethylene glycol
antifreeze and clean water is recommended. This
will provide protection to –34 F (–37 C).
It is extremely important that the antifreeze and
water be mixed in a separate container before
adding to radiator. NEVER add straight antifreeze to
the radiator. The mixture must NEVER be more than
50% antifreeze.

DRAINING THE COOLING SYSTEM

NOTE: Drain the cooling system every 600 hours and
refill with a 50/50 mixture of water and ethylene gly-
col antifreeze.
Drain the cooling system using the following procedure:
DO NOT attempt to remove radiator cap until
engine is allowed to "cool". Radiator contents
are under pressure which can cause spraying
of scalding hot water. Hot water spray can
cause serious injuries.
1. Remove radiator cap when engine is cool. Discon-
nect radiator cooling fan. Open drain cock on bottom
of radiator.
TO PREVENT POSSIBLE SEVERE
BURNS TO YOU OR OTHERS. DO
NOT REMOVE PRESSURE CAP
WHEN HOT. CONTENTS UNDER
1
PRESSURE. CHECK AND ADD
FLUID AT RESERVOIR.
2. Remove bottom radiator hose from radiator to com-
pletely drain engine block.
3. Disconnect hose from water overflow tank and drain
tank. Close radiator drain cock tightly and reinstall
overflow tank hose when both have finished drain-
ing.
ALWAYS recycle or dispose of used antifreeze in a
responsible manner. Used antifreeze can be harmful
to the environment.
4.13
1. Fill radiator to the base of the filler neck and the over-
flow tank to the "FULL" mark with a 50/50 water and
antifreeze mixture. Reinstall reservoir tank cap.
2. Loosen the air bleeding bolt (shown below) until
coolant comes out through the air bleeding hole of
bolt. Resecure the bleeding bolt.
