Operation Manual – ITW GSE 6400 Tier 3
CAUTION
Never use soluble oil in the cooling system.
1) General.
A permanent type antifreeze is recommended for use in the cooling system.
CAUTION
1.
DO NOT
use methanol or alcohol as antifreeze.
2.
DO NOT
mix brands or type of antifreeze. A solution containing two or more types
of antifreeze is impossible to test accurately.
2) Selecting
antifreeze.
a) Select a permanent type antifreeze known to be satisfactory for use with chromate
corrosion resistor.
b) When it is not known if the antifreeze is satisfactory for use with chromate resistor, check
with local engine manufacturer’s representative for a list of compatible antifreezes.
(3) Checking antifreeze solution.
Check the solution with a reliable tester when in doubt about antifreeze protection.
d) Draining the Cooling System
To completely empty the cooling system requires draining the radiator assembly. Follow these
steps to drain the cooling system:
1) Remove
radiator
cap.
2) Place a drain pan with at least a 30 quarts (28.4 liters) capacity under radiator to catch
coolant.
3) Remove the front grill to access the hose & valve. Place the drain hose into the drain pan.
4) Open the radiator drain valve.
5) Allow the system to drain completely.
NOTE:
Be sure the drain valve doesn’t clog during draining.
6) When the system is completely drained, close the drain valve and coil the
hose back up.
7) Replace the front canopy cover.
e) Flushing the Cooling System
Flushing the cooling system should be a yearly maintenance procedure. By flushing the system,
clean water is forced through the engine block to remove expired coolant and other contaminants.
