Where is the coolant temperature sending unit on a 1993 Ford Explorer?

The coolant temperature sending unit (CTS) location on a 1993 Ford Explorer varies slightly depending on the engine (4.0L or 5.0L). However, it's generally found on the intake manifold.

To be certain:

* Look for a sensor with a single-wire connector. The CTS is a relatively small sensor, typically with one wire going to it.

* Trace the wiring. Follow the wire from the sensor – it will lead to the engine's wiring harness. This is often the easiest way to find it, as the sensor itself might be hard to spot.

* Consult a repair manual. A Haynes or Chilton repair manual specific to your 1993 Ford Explorer will show you a diagram with the exact location. This is the most reliable method.

Without knowing the engine size, it's impossible to give a more precise location. But the intake manifold is the most likely place to find it.
