Coolant System
The Blue Bird Electric Bus uses coolant to maintain safe temperature ranges for components
that typically fluctuate during various operating conditions. The coolant keeps the motor and
batteries from overheating during operation and is used to heat the interior of the bus during
cold weather conditions.

WARNING!
WARNING!
Exercise extreme care when removing the cap from the coolant
reservoir. Always allow time for the system to cool before removing the cap.
The pressurized coolant may be very hot and can spray out, causing serious
burn injuries. Use only an original Blue Bird 15 psi pressure cap (10032944), if
replacement is needed.
The coolant level in the reservoir should be checked daily as a part of routine pre-trip inspection. If the coolant level is low, coolant can be
added through the reservoir cap. Use only a 50/50 mixture of distilled or filtered water with DexCool (Orange) coolant safe for aluminum
blocks when replacing or replenishing the coolant. The area around the fill cap should be cleaned before removal to prevent dirt and other
contaminants from entering the system. Damage can occur if particles over 60 micron are introduced into the system.

C AUTION!
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. 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.

Only add tap water in emergency situations. If tap water is used the system should be flushed and
filled with proper coolant at earliest convenience.
