Electrical System
9.14.14 Engine Coolant Temperature Sender
The engine coolant temperature sender (12) is threaded
into the engine block (13) and is connected via the vehicle
sensors wiring harness (14), bulkhead connector and cab
wiring harness to the engine coolant temperature gauge
(16) in the front dash panel. The gauge is located on the
right side of the front dash panel.
The engine coolant temperature sender (12) sends a
signal to the temperature gauge (16) whenever the
engine is running. The gauge monitors the temperature at
which the engine is operating. Glance at the gauge on a
regular basis during operation. If the gauge goes over
210° F (99° C) the engine coolant is too hot. Idle the
engine for 1 minute prior to shutting the vehicle down. If
the radiator is boiling over, SHUT THE VEHICLE DOWN
AS SOON AS PRACTICAL. (Refer to Section 9.10.2,
“Engine Coolant Temperature Gauge Troubleshooting.”)
