Mixing Eg Or Pg Antifreeze And Water - Detroit Diesel EPA07 MBE 4000 Operator's Manual

HOW-TO SECTION
NOTE:
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 standards and
fill the cooling system. For water
requirements, If a concentrated EG
or PG antifreeze is purchased, mix
the antifreeze with water meeting
the required quality standards and
fill the cooling system. For water
requirements, refer to section Water
Requirements. If a pre-diluted, fully
formulated coolant is purchased,
simply 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 of 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.
