Converting a Cooling System from
Conventional Coolant to Long Life
should be used. After the use of Caterpillar
cooling system cleaners, the system MUST
be thoroughly flushed with clean water.
To convert the cooling system from conventional coolant
to Long Life Coolant/Antifreeze, perform the following
Drain the coolant.
Flush the system with clean water to remove any
Use a Caterpillar cleaner to clean the system.
Follow the instructions on the label. Caterpillar
cleaner is available from your Caterpillar dealer.
Drain the cleaner. Flush the cooling system with
Fill the cooling system with clean water. Operate
the engine until the cooling system temperature is
49 to 66°C (120 to 150F).
Drain and flush the cooling system with clean
Repeat Step 5 and Step 6.
Attach a label to the cooling system to indicate the
system has been converted to use Long Life
Recommended - Caterpillar's Diesel
recommendations are for Caterpillar's Diesel
Engine Antifreeze/Coolant only.
Caterpillar's Diesel Engine Antifreeze/Coolant was
specifically designed for diesel engine cooling systems
and natural gas engine cooling systems. Diesel Engine
Antifreeze/Coolant is an alkaline type, ethylene glycol
based formula containing inorganic corrosion inhibitors
and anti-foam agents. Diesel Engine Antifreeze/Coolant
was formulated with the correct additive levels to protect
protection, anti-foam protection, and cylinder liner/block
pitting protection. Use a 30 percent Diesel Engine
water/supplemental coolant additive solution.
Major advantages of Diesel Engine Antifreeze/Coolant:
Minimal silicate content -High silicate coolants, used with
supplemental coolant additives, can cause a buildup of
solids over time. Build-up of solids can cause plugging,
loss of heat transfer, and water pump seal damage.
Diesel Engine Antifreeze/Coolant significantly reduces
solid residue build-up that causes inhibitor dropout and
water pump seal damage.
No need to add supplemental coolant additive on initial
fill -Supplemental coolant additive must be added with
other commercially available coolants.
Diesel Engine Antifreeze/Coolant is available from your
Caterpillar dealer in the following quantities:
3.8 L (1 US gal)
208 L (55 US gal)
