Where is coolant sensor located on a 2003 ford Ranger with 2.3 engine located?

The coolant temperature sensor (CTS) on a 2003 Ford Ranger with a 2.3L engine is typically located on the cylinder head, near the thermostat housing. However, there's a slight chance it might be on the intake manifold depending on the exact configuration of your specific engine.

To be certain:

1. Consult your owner's manual: This is the best resource. It will have diagrams and potentially specific locations for sensors.

2. Use a repair manual: A Haynes or Chilton manual for your specific year and engine will have detailed diagrams and instructions.

3. Online resources: Search online for "2003 Ford Ranger 2.3L coolant temperature sensor location" along with images. You can often find pictures from others who have worked on the same engine.

4. Visual inspection: With the engine cool, carefully look around the thermostat housing and intake manifold area. The CTS is usually a small sensor with a single or two-wire connector. It might be tucked away a bit, so take your time inspecting closely.

Important Note: Before attempting any work on your vehicle, ensure the engine is completely cool to avoid burns.
