Cooling System Level - Check
NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing fluids.
Refer to Special Publication, NENG2500, “Caterpillar
Tools and Shop Products Guide” for tools and supplies
suitable to collect and contain fluids on Caterpillar
products.
Dispose of all fluids according to local regulations and
mandates.
NOTICE
Mixing ELC with other products that do not meet
Caterpillar EC-1 specifications reduces the effective-
ness of the coolant and shortens coolant service life.
Use only Caterpillar products or commercial products
that have passed the Caterpillar EC-1 specification
for pre-mixed or concentrate coolants. Use only
Caterpillar Extender with Caterpillar ELC.
Failure to follow these recommendations can result in
shortened cooling system component life.
When a Caterpillar Extended Life Coolant (ELC) is
used, an Extender must be added to the cooling
system.
Use a 8T-5296 Coolant Test Kit to check the
concentration of the coolant.
Reference: For additional information about the
addition of Extender, refer to Operation and
Maintenance Manual, SEBU6250, “Caterpillar
Machine Fluids Recommendations” or consult your
Caterpillar dealer.

The cooling system pressure cap is located under
the engine hood at the rear of the machine.
1. Slowly loosen the cooling system pressure cap
in order to relieve any system pressure. Remove
the cooling system pressure cap.
2. If necessary, drain enough coolant from the
radiator in order to allow the addition of the
Extender to the cooling system. The cooling
system drain valve is located on the lower left
side of the radiator.
3. Add 0.95 L (32 fl oz) of Extender to the cooling
system.
Reference: Refer to Operation and Maintenance
Manual, “Capacities (Refill)” for the correct
amount.
4. Check the coolant level.
Reference: Refer to Operation and Maintenance
Manual, “Cooling System Level - Check” for the
correct procedure.
5. Install the cooling system pressure cap.

The coolant level sight gauge is located on the
left side of the machine. Maintain the coolant level
within the sight gauge. Add coolant, if necessary.
Note: If it is necessary to add coolant daily, inspect
the cooling system for leaks.
