Where is the temp sending unit on a 96 4 cylinder?

The temperature sending unit location on a 1996 4-cylinder car varies depending on the *make and model* of the vehicle. There's no single answer. It's usually located in the engine block or cylinder head, but the exact position differs significantly between manufacturers (Ford, Honda, Toyota, etc.) and even between models within the same manufacturer.

To find it, you'll need to:

1. Consult your car's repair manual: This is the best resource. It will have diagrams showing the location of all sensors.

2. Use an online parts diagram: Many websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your car's year, make, and model to view parts diagrams. Look for diagrams labeled "engine" or "cooling system." The temperature sending unit is often labeled as "ECT sensor" (Engine Coolant Temperature sensor).

3. Visually inspect your engine: The sensor is typically a one-wire or two-wire sensor screwed into the engine block or cylinder head, often near the thermostat housing. It's usually a small cylindrical part. Be careful when inspecting, as the engine may still be hot.

Without knowing the make and model of your 1996 4-cylinder car, it's impossible to give a more precise location.
