Coolant Temperature Gauge

Coolant Temperature Sender:

The coolant temperature gauge is an electrical gauge that measures current from a water temperature sender in the cylinder head. The sender is in the middle of the cylinder head on the driver's side (4.3L, 5.0L, 5.7L and 7.4L Engines). The 6.5L diesel engine has the coolant temperature sender on the front of the cylinder head. For diagnostic information, Refer to Instrument Cluster System Check.
