How to Replace Spark Plugs & Wires on 2003 - 2023 Chevy Express Van / GMC Savana

Changing out the spark plugs and wires on my 2006 Chevrolet Express 2500 van with 4.8L V8. This should work on all 2003 and newer express and savana cargo vans. When it comes to removing the spark plugs there are many different tool combinations that will work to get the job done. In this video I show just one of many ways. You may have to experiment with different size ratchets, extensions and swivels to get the right lengths to access each spark plug. If you have any questions feel free to ask them in the comments section and I'll do my best to respond.

Update: The van in this video is a 4.8L 2500 chassis. On the 1500 5.3L the passenger front plug is too close to the firewall and the dipstick is in the way. Replacing it was done the same way as the driver front plug, from the engine bay. Just had to take the radiator overflow tank off by removing one bolt and moving it off to the side.
