Mixing Eg Or Pg Antifreeze And Water - Detroit Diesel MBE 900 Operator's Manual

Detroit Diesel Power Cool engine
coolant (part number 23512138) is
the preferred ethylene glycol (EG)
coolant. If other commercial brands of
ethylene glycol are used, they must be
equivalent to the Power Cool. Detroit
Diesel does not market a propylene
glycol (PG) coolant. If a propylene
glycol coolant is used, it must also
meet the following requirements:
□ Fully formulated ethylene
glycol-based, low silicate
antifreeze or coolant must
meet TMC RP-329 "Type A"
requirements.
□ Fully formulated propylene
glycol-based antifreeze or coolant
must meet TMC RP-330 "Type
A" requirements.
Fully formulated antifreeze does not
require a dosage of SCA prior to
initial use.
Mixing EG or PG Antifreeze
and Water — If a concentrated
ethylene glycol (EG) or propylene
glycol (PG) antifreeze is purchased,
mix the antifreeze with water
meeting the required quality
standardslisted in Table 15 and fill the
cooling system.
If a pre-diluted, fully formulated
coolant is purchased, fill the
cooling system. For best overall
performance, a coolant consisting
of 50% concentration of antifreeze

(50% antifreeze, 50% water) is
recommended.
An antifreeze concentration over
67% (67% antifreeze, 33% water) is
not recommended due to poor heat
transfer, reduced freeze protection
(IEG only), and possible silicate
dropout. An antifreeze concentration
below 33% (33% antifreeze, 67%
water) offers too little freeze and/or
corrosion protection and is not
recommended.
