I put the pullies on about 4 years ago or more. At the time everything seemed good to go. When I replace the serpentine and AC belts, I'll give them a bit of attention. Need to check out the wiki DIY section for tips and such.

A few months back I had a leak on the o-ring of the temp sensor in the bottom hose, but nothing noted since. The only time I actually saw the smoke was when the car sat for a week in the very cold weather. Now I just smell it once in a while if I get in traffic.
