Personal injury can result from hot coolant, steam
and alkali.
At operating temperature, engine coolant is hot
and under pressure. The radiator and all lines
to heaters or the engine contain hot coolant or
steam. Any contact can cause severe burns.
Remove filler cap slowly to relieve pressure only
when engine is s topped a nd radiator cap is cool
enough to touch with your bare hand.
Do not attempt to tighten hose connections when
the coolant is hot, the hose can come off causing
burns.
Cooling System Conditioner contains alkali. Avoid
contact with skin and eyes.
NOTI
CE
Do not change the coolant until you read and under-
stand the cooling system information in Special Pub-
lic
ation, SEBU6250, “Caterpillar Machine Fluids Rec-
ommendations”.
Fai
lure to do so could result in damage to the cooling
system components.
NOTICE
Mixing ELC wit
h other products reduces the effective-
ness of the coolant and shortens coolant life. Use only
Caterpillar products or commercial products that have
passed the Cat
erpillar EC-1 specifications for pre-
mixed or concentrate coolants. Use only Caterpillar
Extender with Caterpillar ELC. Failure to follow these
recommendat
ions could result in the damage to cool-
ing systems components.
If ELC cooli
ng system contamination occurs see the
topic Extended Life Coolant (ELC) in the Special Pub-
lication, SEBU6250, “Caterpillar Machine Fluids Rec-
ommendatio
ns”.
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
Dealer Service Tool Catalog” for tools and supplies
suitable to collect and contain fluids on Caterpillar
products.
Dispose of all fluids according to local regulations and
mandates.
If the coolant in the machine is changed to Extended
Life Coolant (ELC) from another type of coolant,
refer to Special Publication, SEBU6250, “Caterpillar
Machine Fluids Recommendations”, “Cat Extended
Life Coolant (ELC)”.
If the coolant is dirty or if you observe any foaming
in the cooling system, drain the coolant before the
recommended interval.
Procedure for the Tractor
1. Park the machine on a level surface and engage
the parking brake. Stop the engine. Allow the
engine to cool.
2. Clean the area around the cooling system
pressure cap of any dirt or debris. This must be
done before the cooling system pressure cap can
be removed.
3. Slowly remove the cooling system pressure cap in
order to release pressure.
