Location of ECT sensor

[HeadKnock]

When cold starting my 1978 Cutlass Supreme... 4.3l 260 v8 engine... my Hot light comes on and stays on. I figured it was the ECT (engine coolant temperature ) sensor, I need to know its location. Is it the one in the intake manifold or the one behind the water pump?

This is a picture of an Olds 350 V8... but its the same engine.

Olds V8's are always in the intake manifold.

Great ... thanks alot... Just curious... do you know what the one is behind the water pump? it looks just like the ECT.

The one behind the water pump on the shelf with big numbers next to it is the oil pressure sensor.
