     Open the hood of your car and remove the negative terminal cable on the battery. Then go to the engine and locate the eight ignition coils that you will have to remove. There are four on each side of the engine and you will have to follow the same procedure for each one. So, disconnect the electrical harness of each coil and then remove the 10 mm bolt using a socket wrench (see image below). Some of the bolts may require a short wrench or extensions, depending on how you find it easier.

    At this point, you can replace all the spark plugs. So, install the replacements carefully (tighten the new spark plugs by hand at first, in order not to damage their threads) and then the ignition coils. Secure them with the bolts and reconnect each harness. In the end, plug back the negative terminal cable on your battery and that’s it. These are the steps you need to follow if you have to replace the spark plugs on your Toyota Tundra V8, 4.8L engine, made between the years 2000 and 2006.
