Where is the engine coolant temperature sensor on a mk4 fiesta 1.3?

The engine coolant temperature sensor (ECT) on a Mk4 Ford Fiesta 1.3 (typically the 1.3L Duratec engine) is usually located on the cylinder head, near the thermostat housing. However, the exact location can vary slightly depending on the specific year and engine variant.

To be certain, I recommend:

1. Consulting your vehicle's repair manual: This will give you the most accurate location with diagrams.

2. Using a Haynes or similar repair manual: These manuals often have detailed diagrams and instructions.

3. Searching online for images: A Google image search for "Ford Fiesta Mk4 1.3 engine coolant temperature sensor location" may yield helpful pictures.

Keep in mind that the sensor itself is usually a relatively small, one or two-wire sensor. It might be difficult to spot without some familiarity with the engine layout. Be careful when looking around the engine; some components can be hot.
