  1. Harmonic Balancer pull

    The "How-To" and DIY Section
    Hi all! I'm in the process of rebuilding my I-6 4200 engine in my 2003 Trailblazer, and out of several things that really irritated me, one of them was getting that darn harmonic balancer (crankshaft pulley) off!!! If you have to deal with this issue, you probably know there's very little...
