    Wimps.

    That being said, I'd do the exact same thing if they were close enough to me...I have to do this soon.

    Well... I was lucky that the car made it home and I had the skills, an extra car in the family, most of the tools and the internet handy for research while the new part was on the way. By fixing it myself I not only saved paying a mechanic, but also the tow that would have been required as the car was DOA... not going anywhere without overheating within a minute or so of running the engine.

    This isn't a horribly difficult job, but it was made much easier by having a garage (something not everyone is lucky enough to have) and a compressor/impact wrench.

    To the folks who opted to have the problem fixed by the professionals: May we ask the price you paid (or at least a # of shop-hours charged, so we can do the math using local mechanic's pricing and add the $ for parts)?

    Thanks for posting the DIY. I decided to tackle this while on vacation this week. Purely a preventative measure.

    I used a harbor freight puller kit and some 6mm class 10.9 bolts and some washers sourced from menards. Worked like a charm. Had a bit of interference between the puller tool and the car chassis, but that would have been resolved by using some longer bolts. I used the longest I could find (75 mm IIRC) and made it work. Heated the new pulley in the oven on 250 for about ten minutes and it went on with ease.

    One less thing to worry about blowing apart now.
