DPSG,OUOD002,1921 –19–27JUL06–2/2
IMPORTANT: ALWAYS maintain coolant at correct
level and concentration. DO NOT
operate engine without coolant even for
a few minutes.
If frequent coolant makeup is required,
the glycol concentration should be
checked with JT07298 Coolant/Battery
Tester to ensure that the desired freeze
point is maintained. Follow
manufacturer’s instructions provided
with Coolant/Battery Tester.
Add the manufacturer’s recommended concentration of
supplemental coolant additive. DO NOT add more than
the recommended amount.
The use of non-recommended supplemental coolant
additives may result in additive drop-out and gelation of
the coolant.
If other coolants are used, consult the coolant supplier
and follow the manufacturer’s recommendation for use of
supplemental coolant additives.
See DIESEL ENGINE COOLANTS AND
SUPPLEMENTAL ADDITIVE INFORMATION for proper
mixing of coolant ingredients before adding to the cooling
system.
