10.8.22 Engine Block Heater (
option
)
Some engines are equipped with an optional engine
block heater (Fig. 10– 105) that can be plugged into a
standard 110/120V ac grounded outlet to heat the engine
coolant. When temperatures are below 10° F (-12° C),
the block heater should be used.
Figure 10– 105. Some engines are equipped with an
optional engine block heater.
For further information, consult the appropriate engine
manual or the nearest engine distributor.
10.8.23 Fuel Level Indicator
and Fuel Level Sender
The fuel level indicators on the left side of the operators
display panel (Fig. 10– 106) work in conjunction with the
fuel level sender (Fig. 10– 107, next page).
The submerged, coil-type fuel sender is secured to the
fuel tank beneath the cab and is connected via the
engine wiring harness, bulkhead connector and cab wir-
ing harness to the operators display panel.
Figure 10– 106. Operators display panel indicators.
The operators display panel fuel level indicator bars on
the left of the operators display panel illuminate to show
the approximate fuel level in 1/4 tank increments. The
fuel level indicator bars will be illuminated with a low-light
green hue, easily apparent for night visibility and in low-
light conditions. When approximately 1/8 tank is reached,
the last fuel level indicator bar will stop illuminating, and
the fuel level indicator symbol will change from green to
orange. When the fuel level indicator symbol changes
from green to orange, refuel the tank.
The fuel level sender wiring harness connector can be
accessed from beneath the cab without removing the
cab. The cab must be removed to access the fuel tank
and fuel sender. See
Section 4 Cab, Covers and Mirrors
in this manual for cab and fuel tank removal instructions.
