DYNASTY 2006 CHASSIS INFORMATION — SECTION 10 • 343
STARTING PROCEDURE
Normal Starting
The engine is equipped with an intake manifold grid heater. The grid heater helps engine starting in cold
weather. Intake manifold air temperature is monitored by the Electronic Control Module on the engine. If intake
manifold temperature is below specifi ed level (approximately 40º F.), the manifold grid heater will activate. Grid
heater activation is indicated by the WAIT TO START indicator lamp.
WARNING:
Use of ether starting fluids may cause an explosion upon grid heater activation.
To Start the Engine:
With the throttle in idle position, turn ignition to ON. Allow the WAIT TO START lamp to extinguish. Turn key
to the start position. When the engine starts the grid heater will again energize for a time period determined by the
Electronic Control Module. Allow the engine to idle with no load for three to fi ve minutes. The engine coolant
temperature should be up to normal operating range (140º F/60 º C to 212º F/100º C) before operating the engine
under full throttle.
NOTE:
It is recommended to not idle the engine for long periods of time. Consistent periods of long
idle wastes fuel and may cause engine damage.
Cold Weather
In sub-freezing or extreme cold, engine oil becomes thick and battery output is reduced. Thick oil, combined
with less amperage available from the battery, increases diffi culty in starting the engine.
Depending on ambient temperature it may be necessary to pre-heat the engine. Located in the coolant passage in
the engine is a heating unit that operates from 120 Volt AC. If it is necessary to pre-heat the engine due to ambient
temperature, it is recommended to activate the block heater the night before, allowing several hours for the block
heater to warm the engine.
Another method to preheat the engine is to use the Aqua-Hot. The
optional Aqua-Hot engine pre-heat function will heat engine coolant
and the interior. An indication of 100º F or higher of the engine
temperature gauge should be suffi cient for the engine to start.
It is possible to operate diesel engines in extremely cold
environments when the engine is properly equipped with the
correct lubricants, fuels and coolant. Cold weather operation can
be defi ned in two categories: Winter and Arctic.
WINTER (32º to -25º F) (0º to -32º C): Use a 50% antifreeze to 50% water coolant mixture, use
multi-viscosity oil meeting manufacturers specifi cations and fuel to have maximum cloud pour points
10º F (6º C) lower than the ambient temperature in which the motorhome operates.
ARCTIC (-25º to -65º F) (-32º to -52º C): Use a 60% antifreeze to 40% water coolant mixture. Use
oil meeting manufacturers specifi cations and fuel to have maximum cloud pour points 10º F (6º C)
lower than the ambient temperature in which the motorhome operates.
