Where is the engine coolant temperature sensor on a 2001 Buick LaSabre?

The engine coolant temperature sensor (ECT) on a 2001 Buick LaSabre is typically located on the engine block, near the thermostat housing. However, the exact location can vary slightly depending on the engine (3.8L Series II or the less common 2.0L).

To locate it precisely:

1. Consult your vehicle's repair manual: This is the most reliable method. The manual will have diagrams and specific instructions.

2. Look near the thermostat housing: This is the most common location. The sensor is usually a relatively small part, often with a single wire connector.

3. Follow the coolant temperature sensor wire: Trace the wire coming from the sensor connector; this will lead you to its location on the engine.

Caution: The engine will be hot if recently run. Allow it to cool completely before attempting to locate the sensor.

Without a specific engine code (e.g., 3800 Series II), providing a more precise location is difficult. Using a repair manual or searching online for "2001 Buick LaSabre [3.8L or 2.0L] engine coolant temperature sensor location" with images will give you the best chance of finding it.
