with coolant filters or conditioners.
CAUTION
Do NOT use soluble oil-type coolants in any MACK cooling system.
Cooling System Maintenance
The cooling system must be maintained by performing regularly scheduled
maintenance as outlined in the Maintenance and Lubrication Manual
(21394653). Cold weather operations, however, place added demands on the
cooling system. Prevent potential cold weather problems by performing a
quick check of the cooling system as outlined below:
• Make a general check for cooling system leaks.
• Inspect hoses and clamps for leaks and condition. Tighten hose clamps to
specifications (as required).
• Check coolant level. Add fresh coolant (in specified concentration) as
necessary.
• Check and record degree of antifreeze concentration. Add antifreeze as
necessary to obtain required protection level.
For additional information concerning the cooling system, refer to the
Maintenance and Lubrication Manual (21394653) .
