MAINTENANCE AND LUBRICATION 283
Ethylene glycol or propylene glycol-based antifreezes are both approved for
all MACK engines. All ethylene glycol and propylene glycol coolants must
be low-silicate antifreezes which meet ASTM4985 test (GM6038M SPEC)
criteria. These antifreezes are sometimes referred to as heavy-duty diesel
coolants. Passenger car coolants do NOT meet this specification.
Be sure to maintain the required level of antifreeze protection for anticipated
winter temperatures in your area of operation. A 40% to 60% concentration of
antifreeze is required for MP engines, regardless of application, geographic
location or ambient air temperature.
CAUTION
Do NOT exceed a 60% concentration of antifreeze to water. A higher percentage of
antifreeze will not increase protection. Concentrations over 60% adversely affect
freeze protection and heat transfer rates.
Note:
Propylene glycol should be checked with a refractometer.
Note:
ALWAYS mix the water/antifreeze solution before pouring it into the cooling
system.
Note:
The piping arrangement may cause capacity variation depending on the type
of cooling system and optional external cooling devices which may be attached.
Therefore, it is difficult to tell exactly how much coolant it will take to fill any one
particular system.
CAUTION
Do NOT use coolant solutions which contain anti-leak additives in trucks equipped
with coolant filters or conditioners.
CAUTION
Do NOT use soluble oil-type coolants in any MACK cooling system.
