Cooling System Level - Check
When a Caterpillar Extended Life Coolant (ELC) is
used, an extender must be added to the cooling
system. See the Operation and Maintenance
Manual, “Maintenance Interval Schedule” for the
proper service interval. The amount of extender is
determined by the cooling system capacity.
For additional information about an extender, see
Operation and Maintenance Manual, SEBU6250,
“Caterpillar Machine Fluids Recommendations” or
consult your Caterpillar dealer.

4. Look into filler tube (1). If necessary, add
premixed coolant in order to correct the coolant
level. Maintain the coolant level between area (2)
and area (3) of the filler tube. Adding coolant
above this area of the filler tube will cause the
coolant to overflow the cooling system.
5. Inspect the filler cap gasket. Replace the filler
cap if the gasket is damaged.
6. Install the filler cap.

1. The filler cap is located inside the access door
on the top, left side of the radiator guard. Slowly
loosen the filler cap in order to relieve the
pressure. Remove the cap.
2. Add ELC. Drain some coolant from the radiator
into a suitable container in order to allow space
for the extra ELC.
Note: Always discard drained fluids according to
local regulations.
3. Start the engine. Run the engine without the filler
cap until the thermostat opens and the coolant
level stabilizes. Check for leaks.

Cooling System Level - Check
SMCS Code: 1353-535-FLV; 1395-535-FLV
At operating temperature, the engine coolant is
hot and under pressure.
Steam can cause personal injury.
Check the coolant level only after the engine has
been stopped and the fill cap is cool enough to
touch with your bare hand.
Remove the fill cap slowly to relieve pressure.
Cooling system conditioner contains alkali. Avoid
contact with the skin and eyes to prevent personal
injury.
This machine’s radiator has a surge tank. There is
no top tank in this cooling system. The surge tank
has a filler cap and a sight glass. It is not necessary
to remove the filler cap in order to check the
coolant level. The sight glass is inside the engine
compartment that is on the front left side of the
machine. The filler cap is beneath the access door
that is on the top left side of the radiator guard.
