Where is the engine coolant temperature sensor located in a 1987 Camaro z28 Iroc-z?

The engine coolant temperature sensor (ECT) on a 1987 Camaro Z28 IROC-Z is typically located on the cylinder head, near the thermostat housing. However, the exact location can vary slightly depending on the engine (a 305 or 350 cubic inch small block Chevrolet).

To be certain, you should:

1. Consult a repair manual: A Haynes or Chilton manual specific to your 1987 Camaro Z28 IROC-Z will have a diagram showing the exact location. This is the most reliable method.

2. Look at diagrams online: Websites like autozone.com or others offering parts diagrams often show the sensor location based on your vehicle's VIN or engine type. Be cautious; ensure the diagram matches your specific year and model.

3. Visually inspect the engine: The sensor is usually a single-wire or two-wire sensor, often with a connector easily visible, and positioned where the coolant would flow readily. Look near the thermostat housing and upper radiator hose connections.

Remember to let the engine cool completely before attempting to locate or replace the sensor. Coolant is hot and under pressure, and you can seriously burn yourself if you're not careful.
