COLD WEATHER

With the throttle in the idle position, turn the key to the start position.
When the engine has started release the key. Allow the engine to idle with no
load for three to five minutes. The engine coolant temperature should be up to
normal operating range (140º F / 60º C to 212º F / 100º C) before operating the
engine under full throttle.
NOTE: The ISM engine does not have a "wait to start" feature.
If the motorhome has an Aqua-Hot, the Engine Heat function will heat the
engine coolant and heat the interior. An indication of 100º or higher of the engine
temperature gauge should be sufficient for the engine to start.
NOTE: The engine is filled with 15-40w multi-viscosity oil from the
factory. Generally this will start the engine in temperature down to
15º F. If the engine has normalized to a temperature below 15º F. it
will be necessary to pre-heat the engine before starting.
CAUTION: Upon cranking an engine in cold temperature, the starter
may rapidly engage and disengage. If this occurs STOP attempting to
crank the engine as starter damage may occur. Pre-heat the engine
before making any more attempts to start the engine.

In sub-freezing or extreme cold,
engine oil becomes thick and battery out-
put is reduced. Thick oil combined with
less amperage available from the battery
increases difficulty 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.
