Trailblazer LS Straight 6

  • Automatic transmission
  • 52,000 miles

Ticking noise did not change with RPM. I got out my stethoscope and looked everywhere. Could not figure out where it was coming from. I finally noticed it went away when the fan clutch fully engaged as engine heated up. O'Reilys had a replacement for about $175.00. Installed it in 25 minutes. No problems other than the fan is quite noisy when fully engaged.

three times in with the ticking sound and finally was told it was the cooling fan clutch. Too bad by this time my warranty had ran out and because they did not write it down and sent me on my way, I had to pay.
