* On the sides of the engine block: These are the most common locations. You'll find them recessed into the block itself. You'll need to look carefully along the sides of the engine, potentially needing to clean some grime away to see them.
* At the back of the engine block: There might be one or more near the transmission. Access here is more difficult.
Important Considerations:
* Visual Inspection Required: There's no single definitive diagram showing their exact position for all 1996 Tahoe 5.7L engines. You *must* visually inspect the engine block.
* Repair Manual: A repair manual specific to your year and engine is highly recommended. It will have diagrams and details on location and replacement procedures.
* Accessibility: Accessing some freeze plugs can be difficult. You may need to remove some components (like the starter motor or other peripherals) for better visibility and access.
Remember, working on an engine requires mechanical knowledge and skill. If you're not comfortable performing this task, it's best to take your vehicle to a qualified mechanic. Replacing a freeze plug incorrectly can lead to significant engine damage.
