CHASSIS INFORMATION
• Fluid level rises as temperature increases. Fluid must be hot to
ensure an accurate check.
• Be sure fluid has reached normal operating temperature
(160º - 200º F /71º - 93º C). If a transmission temperature gauge is
not present, check the fluid level when the engine water
temperature gauge has stabilized and the transmission has been
operated under the load for at least one hour.
• Park the motorhome on a level surface and shift to N (Neutral).
Apply the parking brake and allow the engine to idle
(500 - 800 RPM).
• After wiping the dipstick clean, check the fluid level. Safe operating
level is anywhere within the HOT RUN band on the dipstick.
• The width of the HOT RUN band is approximately one quart of
fluid at normal temperature range.
• If the level is not within this band, add or drain the fluid as
necessary to put the level within the HOT RUN band.
• Be sure that the fluid level checks are consistent. Check the level
more than once. If the readings are not consistent, ensure that the
transmission breather is clean and not clogged. If the readings are
still not consistent, contact the nearest Allison distributor or dealer.
The cooling system consists of a rear mounted radiator an
in-line transmission cooler, as well as a charge air cooler that are
mounted to the radiator. Steel tubes and radiator hoses allow
engine coolant to flow between the radiator and the engine. The
fan draws air from the out back of the engine compartment.
These components working together ensure that all the chassis
systems maintain proper operating temperatures as they are
inter-related. A problem with one component may cause
problems with an entirely different system.
After the engine reaches proper temperature, the water
regulator (thermostat) on the engine opens and allows coolant to
flow from the engine, through the upper radiator hose and into the
radiator. The coolant is cooled in the radiator and flows back to
the engine through the lower radiator tube. A bypass tube
installed between the thermostat housing and lower radiator tube
functions to supply coolant to the transmission cooler under certain
conditions to ensure proper cooling.
CAUTION: Do not place or mount any item on the back of the
motorhome which may block the grill opening or change the air
flow. This may result in an overheating condition under some
circumstances.
