Injector cup replacement anyone

[deadlyman]

I have a 01 duramax alli 3500 4x4 have the same coolant problem I had under warrenty a while back I need to change the injector cups maybe the head gaskets don't trust dealers and don't know any local shops to trust to work on my truck. how hard to replace myself?

If you're a reasonably good backyard mechanic and have the GM service manuals, you should be successful... :)

Take your time, and label & photograph the various layers of components that need to be removed to get down to the head gaskets..
