Change engine coolant to Organic Acid Technology (OAT) coolant
Depending on the date of manufacture, your cooling system may be equipped with conventional ethylene glycol
coolant such as IAT COOLANT 11 – CLASSIC or an Organic Acid Technology (OAT) coolant solution such as EXTENDED
LIFE OAT COOLANT/ANTIFREEZE. You can easily identify EXTENDED LIFE OAT COOLANT/ANTIFREEZE by its yellow color.
You should never mix the coolant types.
The coolant solution used must meet the following CNH
Industrial material specications for either coolant type:
•
MAT3624 for OAT coolant
•
MAT3620 for conventional coolant
The decal shown is located near the ll point of the cool-
ing system whenever the factory ll is EXTENDED LIFE OAT
COOLANT/ANTIFREEZE. This decal is available in three dif-
ferent sizes. See the table below for the associated part
numbers.

47757332 100 mm x 100 mm
47757330 1
NOTICE: NEVER mix OAT coolant with conventional coolant. Under no circumstances should you top off a cooling
system with only water. You can use a refractometer to check the concentration level. You should not use Supple-
mental Coolant Additives (SCA) when using EXTENDED LIFE OAT COOLANT/ANTIFREEZE. Change the coolant solution
at the recommended change interval.
If you need to change a machine from conventional coolant to OAT coolant or vice versa, you should follow the
“Changing coolant types” procedure below to attain the full benet of the coolant.
Changing coolant types
To change coolant from OAT coolant to conventional coolant (or vice versa):
1. Empty the engine cooling system by draining the coolant into a suitable container.
2. Fill the system with clean water.
3. Start the engine and run the engine for at least 30 min.
NOTE: Make sure that you activate the heating system (if equipped) to circulate uid through the heater core.
4. Repeat Steps 1 to 3 for a total of two washes.
5. Fill the system with conventional coolant (or OAT coolant).
6. Operate the engine until it is warm. Inspect the machine for leaks.
7. If you are changing to OAT coolant, then attach the decal (CNH Industrial part number 47757330) to indicate the
use of OAT coolant in the cooling system.
