Engine Coolant High Temperature
Sender

The engine coolant high temperature sender (Fig. 9-89, 1)
is threaded into the engine block (2) and is connected to
the operator’s instrument cluster via the engine wiring
harness, bulkhead connector and cab wiring harness.

Figure 9-89 Engine Coolant Temperature Sender

When the engine coolant temperature exceeds normal
operating limits and rises above 210° F (99° C), the
sender closes contacts within the sending unit. The
operator’s instrument cluster indicator (Fig. 9 -90, 1)
illuminates.

When the engine coolant temperature is below 210° F
(99° C), the contacts within the sending unit open and the
instrument cluster indicator turns OFF. (Refer to Section
9.9.2, “Engine Coolant Temperature Warning Indicator
Troubleshooting.”)
