Replacing spark plugs on a Chevy Tahoe involves several steps. Here is a general guide on how to do it. Keep in mind that this is a general outline and you should always refer to your vehicle's specific manual for any particularities or special instructions.

**Tools and Materials Needed:**
- New spark plugs (make sure they are the correct type and gap for your specific Tahoe model)
- Spark plug socket and extension (usually 5/8" or 16mm)
- Ratchet wrench
- Spark plug gap tool (if the plugs aren't pre-gapped)
- Torque wrench
- Anti-seize compound (optional, but recommended)
- Dielectric grease (optional, for protecting electrical connections)

**Steps:**

1. **Gather Supplies:**
- Make sure you have all the necessary tools and the correct replacement spark plugs.

2. **Locate the Spark Plugs:**
- The spark plugs are typically located on the sides of the engine block, with wires or coils leading to them.

3. **Prepare the Area:**
- Ensure the engine is cool to the touch. Cleaning around the spark plugs with compressed air or a small brush can prevent debris from falling into the combustion chamber.

4. **Remove the Spark Plug Wire/Coil:**
- If your Tahoe has spark plug wires, carefully remove one at a time by firmly gripping the boot (the part on the plug) and gently twisting while pulling upward. If it has individual coil packs, you'll need to unbolt them and then disconnect the electrical connector.

5. **Remove the Old Spark Plug:**
- Using a spark plug socket and an extension, carefully loosen and then remove the old spark plug. Be cautious not to apply excessive force, as you could damage the threads.

6. **Inspect and Gap the New Spark Plug:**
- Check the gap on the new spark plug using a spark plug gap tool. Adjust if necessary. Some plugs come pre-gapped, but it's always a good idea to double-check.

7. **Install the New Spark Plug:**
- Thread the new spark plug into the socket by hand to ensure you don't cross-thread it. Then, use the ratchet wrench to snugly tighten it. Be careful not to over-tighten, as you can strip the threads.

8. **Replace Spark Plug Wire/Coil:**
- Reattach the spark plug wire or coil pack. If you're using spark plug wires, make sure they're pushed down firmly onto the spark plug.

9. **Repeat for Remaining Spark Plugs:**
- Repeat steps 4 through 8 for each of the remaining spark plugs.

10. **Torque to Specifications (if necessary):**
- Refer to your vehicle's manual for the specific torque value and use a torque wrench to ensure the plugs are properly seated.

11. **Apply Dielectric Grease (optional):**
- A small amount of dielectric grease on the inside of the spark plug boot can help protect against moisture and ensure a good electrical connection.

12. **Reassemble and Test:**
- Put everything back in place, start the engine, and listen for smooth, even running. Check for any error codes or misfires.
