2004 Chevrolet Trailblazer Q&A

2004 Chevrolet Trailblazer Question: Loud engine rumbling noise - changes in drive/park and when a/c off better.

It gets louder when I accelerate from stops. I've seen answers to similar questions - poss water pump or fan clutch. How easy are these to replace myself? Thanks! -
