Coolant Recommendations For Volvo D13 Engine - PREVOST H3-41 Maintenance Manual

SECTION 05B: X3 SERIES COOLING SYSTEM
6.4 COOLANT RECOMMENDATIONS FOR
VOLVO D13 ENGINE
The coolant provides a medium for heat transfer
and controls the internal temperature of the
engine during operation. In an engine having
proper coolant flow, some of the combustion
heat is conveyed through the cylinder walls and
the cylinder head into the coolant. Without
adequate coolant, normal heat transfer cannot
take place within the engine, and engine
temperature rapidly rises.
To function properly, the cooling system must be
pressurized to prevent localized boiling of
coolant. The system must be kept clean and
leak-free. The filler and pressure caps must be
checked periodically for proper operation.
Always maintain cooling system at the proper
coolant level. Check daily, use recommended
extended life coolant
antifreeze and deionized water mixture ratio.
This ratio 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 located on the surge tank provides
information on recommended coolants.
CAUTION
On Volvo D13 engine, use only Extended
Life Coolant (ELC).
supplemental coolant additives (SCA) to
extended life coolant. Do not use a
coolant filter containing Supplemental
Coolant Additives (SCA).

Recommended coolants for Volvo D13
engine:
 Texaco CPS#227998 (pre-diluted 50/50
mixture);
 Chevron CPS#227811 (pre-diluted 50/50
mixture);
 Volvo
20358716
mixture);
The ELC coolant slow depleting additive
chemistry does not require regular testing, but
the coolant can be tested with a FleetFix®
Maintenance Test Strip (to measure nitrite and
carboxylate levels) and the FleetFix® Dilution
Test Kit (to determine contamination and
protection levels of the ELC coolant).
The freeze protection level should be checked at
least twice a year using a coolant refractometer.
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.
