Here's a more detailed breakdown:
1. Identify the intake manifold: This is the large, aluminum casting that sits on top of the engine.
2. Locate the thermostat housing: Look for a cylindrical housing attached to the bottom of the intake manifold. It might be metal or plastic.
3. The thermostat is inside: The thermostat itself sits inside the housing. You'll likely need to remove the housing to access the thermostat.
Important Note:
* Different models: The exact location of the thermostat housing can vary slightly depending on the specific Firebird model and engine configuration.
* Visual aid: Using a repair manual or online resources like YouTube videos specific to your year and model Firebird can help you find the exact location.
Always remember: Before working on your vehicle, disconnect the battery to avoid electrical hazards.
