Engine Coolant Reservoir (Detroit):
The engine coolant reservoir is connected to the radiator by a
hose. When the motorhome is driven, coolant heats and expands. A
portion of fluid displaced by expansion flows from the radiator into
the reservoir tank. When the engine is stopped, the coolant cools and
contracts. Coolant is drawn back in the radiator by a vacuum. Thus,
the radiator is kept filled with coolant to the desired level at all times
resulting in increased cooling efficiency. The coolant level should be
at the sight glass on the reservoir tank when the system is cold.
CAUTION:
To avoid scalding hot steam or coolant from being
released from the engine cooling system, never remove
the reservoir cap while the engine is running or hot.
Failure to follow this warning may result in damage to
the engine’s cooling system and possibly cause severe
personal injury.
• Check the coolant level when refueling.
• If the coolant is below the minimum level, the low coolant alarm will sound and the low
coolant light will appear on the dash.
• The coolant level in the reservoir is visible in sight glass as green.
INSPECTION:
Stop the motorhome and inspect the coolant level before continued operation.
