Where is the temperature sending unit on a 2.2 Chevrolet Cavalier engine?

The temperature sending unit on a 2.2L Chevrolet Cavalier engine is typically located on the cylinder head, near the thermostat housing. It's usually a small, one-wire sensor. However, there might be *two* sensors: one for the gauge and one for the computer (ECM). The exact location can vary slightly depending on the year of the Cavalier.

To be certain, you should:

* Consult your vehicle's repair manual: This will have a diagram showing the exact location of all sensors.

* Look closely at the cylinder head: Examine the area around the thermostat housing; the sending unit will be a relatively small component with a single or dual wire connector.

* Use a diagram specific to your year and engine code: Online parts catalogs (like AutoZone, Advance Auto Parts, etc.) often have diagrams you can access using your vehicle's VIN.

Without knowing the precise year of your Cavalier, a more specific location can't be given.
