Engine cooling system - Basic instructions
D150C
Depending on the date of manufacture, your cooling system may be equipped with conventional ethylene glycol
coolant such as CNH XHD H
tion such as NEW HOLLAND AMBRA ACTIFULL™ OT EXTENDED LIFE COOLANT. You can easily identify NEW
HOLLAND AMBRA ACTIFULL™ OT EXTENDED LIFE COOLANT by its yellow color. You should never mix the
coolant types.
The coolant solution used must meet the following CNH
Industrial material specifications for either coolant type:
• MAT3624 for OAT coolant
• MAT3620 for conventional coolant
The decal shown is located near the fill point of the cool-
ing system whenever the factory fill is NEW HOLLAND
AMBRA ACTIFULL™ OT EXTENDED LIFE COOLANT.
This decal is available in three different sizes. See the ta-
ble below for the associated part numbers.

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 Supplemen-
tal Coolant Additives (SCA) when using NEW HOLLAND AMBRA ACTIFULL™ OT EXTENDED LIFE COOLANT.
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 benefit 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 fluid 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.
