Engine coolant temperature sensor

[Herculean T4R]

Where is engine coolant temperature sensor that sends signal to cluster gauge located in the engine bay?

I know the location of the sensor that sends info to the ECU but can't locate the second sensor.

A pic will be helpful.

Thanks!

See post #11 and post #29.

Its behind the engine and hard to get to/see.

The sensor in the front behind the timing cover is one that sends the signal to the ECM. The one on the back of the engine is the for the gauge cluster.

back right of the engine up against the firewall. Most likely will need to remove the Heater core hoses for easier access I changed mine it was "that" hard. I took off my hood also, Either a 10 or 12 mm deep socket fit over the sensor and out she came.
