Operation Manual – ITW GSE 6400 Tier 3
f) Cleaning the Radiator Core
Blow out accumulated dirt from the radiator core air passages, using water. Bent or clogged
radiator fins often cause engine overheating. When straightening bent fins, be careful not to
damage the tubes or to break the bond between fins and tubes.
NOTE: Direct the water in a reverse direction to normal air flow. Normal flow on this installation
is from the engine compartment out ward.
g) Filling the Cooling System
The preparation and monitoring of coolant in liquid-cooled engines is especially important
because corrosion, cavitation, and freezing can lead to engine damage. For coolant system
protection details see the engine manufacturer’s operations manual.
1) Install coolant
a) Remove radiator cap. Be sure the radiator drain valve is closed (Front panel must be
removed to access this location).
b) Pour coolant into radiator very slowly until it reaches the bottom of fill neck. Allow time for
trapped air to escape from the system then continue filling until the coolant level remains
at the bottom of the fill neck.
c) Start the engine and bring up to rated speed and allow the thermostat to open. Add
coolant as trapped air escapes from the system and the coolant level falls.
d) Continue to check coolant level until all trapped air escapes. Add coolant if needed to fill
to the bottom of fill neck. Install radiator cap.
2) Inspection/Check
a) Check system for evidence of leaks.
b) Inspect all hoses. Install new hoses as necessary. Tighten hose clamps as required.
c) Check the condition of fan and water pump belts. Replace belts if necessary.
NOTE: It is good practice to attach a card, indicating the cooling system contents and date
serviced, to the radiator filler neck.
h) Thermostat
The thermostat should be checked each fall, or as required. Refer to engine manufacturer’s
operations manual for recommended instructions.
