Blue Bird installs a decal on or near the deaeration tank filler which state the type
of coolant installed at the factory. The decal states the approved premixed coolant
and coolant manufacturer’s part number for one gallon quantities. The decal also
lists the manufacturer’s part number for the concentrate which is approved for mix-
ing with the premix for stronger glycol concentration. Another decal near the fill
neck indicates warnings for the service technician.
[CAUTION] When replenishing or replacing coolant, only use coolant of the
same type already installed. Never mix coolants of different color, type, or
brand. Plain water is corrosive at engine operating temperatures. Never add
plain water to the system. When using concentrated coolant to raise the glycol
concentration for extreme temperature environments, Blue Bird recommends
only mixing the concentrate with pre-mixed coolant of the same type; not
mixing with water.
coolant Testing and replacement
Each engine manufacturer has its own specific requirements for coolant testing and
maintenance. Therefore, refer to the engine Operator’s Manual for your bus and fol-
low the engine manufacturer’s maintenance specifications.
Blue Bird recommends strictly abiding by the engine manufacturer’s testing and
maintenance schedules and draining, flushing, refilling procedures to maintain com-
pliance with the engine warranty requirements. Blue Bird also recommends that you
maintain accurate vehicle-specific service records of all coolant system maintenance
procedures performed.
The cost of the testing is the owner’s responsibility as part of the engine manu-
facturer’s requirements for testing and maintaining the engine and coolant.
For Cummins engines using Fleetguard ES Compleat coolant, send coolant
samples to Fleetguard for Monitor C testing, as specified in the Cummins Operator’s
Manual. Label sample as Conventional coolant.
For Cummins engines using Fleetguard ES Optimax extended life coolant, send
coolant samples to Fleetguard for Monitor C testing, as specified in the Cummins
Operator’s Manual. Label sample as Extended-Life coolant.
[CAUTION] Never mix coolant types.
Routine coolant addition (top-off) must match the installed coolant type and
brand. Do not mix coolants of different colors, types, or brands in the same engine.
[CAUTION] Always mix concentrate with premix coolant, not water.
If concentrated coolant is added in order to raise the glycol ratio, use only the
concentrate version of the same premix coolant type and brand as installed. Do not
mix the concentrate with water. Instead mix the concentrate with the premix version
of the same coolant.
