The instructions I have are for these engines, if you have a different engine, let me know and I might be able to find them. They are very basic, so they presume you have the correct tools and mechanical ability to perform this repair.
4.8L, 5.3L & 6.0L Engines
1. Disconnect the negative battery cable.
