Cooling System Safety
•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
Coolant Specification
The coolant reservoir is filled at the factory with a
50/50 solution of water and ethylene glycol base
extended-life coolant.
Important:
Use only commercially available
coolants that meet the specifications listed in the
Extended Life Coolant Standards Table.
Do not use conventional (green) inorganic-acid
technology (IAT) coolant in your machine. Do
not mix conventional coolant with extended-life
coolant.

Important:
Do not rely on the color of the coolant
to identify the difference between conventional (green)
inorganic-acid technology (IAT) coolant and extended-life
coolant.
Coolant manufacturers may dye extended-life coolant in
one of the following colors: red, pink, orange, yellow,
blue, teal, violet, and green. Use coolant that meets the
specifications in the Extended Life Coolant Standards
Table.

D3306 and D4985 J1034, J814, and 1941
Important:
Coolant concentration should be a
50/50 mixture of coolant to water.
•
Preferred: When mixing coolant from a
concentrate, mix it with distilled water.
•
Preferred option: If distilled water is not available,
use a pre-mix coolant instead of a concentrate.
•
Minimum requirement: If distilled water and
pre-mix coolant are not available, mix concentrated
coolant with clean drinkable water.
Checking the Coolant Level
Service Interval: Before each use or daily
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and
cause burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Prepare the machine for maintenance; refer to
Checking the Coolant Level (page 62) .
2. Open the hood, and wait for the engine to cool;
refer to
Opening the Hood (page 41) .
3. Carefully remove the radiator cap ( Figure 108 ).

4. Check the coolant level in the radiator.
Note:
The coolant level is correct if it is to the
top of the filler neck of the radiator ( Figure 108 ).
5. Check the coolant level in the expansion tank.
