POWER TRAIN GRT9165 SERVICE MANUAL
7-2
Published 10-01-2020 Control # 699-00
The air intake filter is mounted on the right rear fender. The
muffler is mounted on the left side of the carrier between the
rear axles.
The engine is equipped with electric air heating elements
located in the engine intake air stream to aid in cold starting
and reduce white smoke at start-up. In preheat mode, the
engine should not be cranked until Wait-to-Start Lamp turns
off. The Wait-to-Start Lamp is illuminated during the preheat
time that takes place when the ignition switch is in the ON
position during cold weather starting. The ECM checks
information it receives from various sensors on the engine to
determine how long to energize the air heater before
extinguishing the Wait-to-Start Lamp. Once the engine is
started, the electric air heating element will be energized
again for a time period determined by intake air temperature.
