5.6 COOLANT RECOMMENDATIONS FOR
VOLVO D13 ENGINE
Coolant mixture consisting of 50/50 antifreeze
and deionized water solution should be used
year-round to provide freeze and boil-over
protection as well as providing a stable
environment for seals and hoses.
When topping up coolant, use the same coolant
mixture type as the mixture already in the
cooling system. Do not mix two different types of
coolant.
Do not use antifreeze formulated for automobile
gasoline engines, these have a very high silicate
content that will clog the radiator and leave
unwanted deposits in the engine.
A decal (053487) located on the surge tank
provides information on recommended coolants.
Recommended coolants for Volvo D13
engine:
•
Prevost #685241 (pre-diluted 50/50
mixture);
•

CAUTION
On Volvo D13 engine, use only Extended Life
Coolant (ELC). Do not add supplemental
coolant additives (SCA) to extended life
coolant.
Do not use a coolant filter containing
Supplemental Coolant Additives (SCA).
CAUTION
Extended Life Coolant (ELC) will test as out of
additives (SCA), but SCA should not be
added. Shortened engine life may be the
result of adding SCA.
