| Post subject: | Engine noise after timing belt change |
Recently my '03 KJ 2.8 CRD went through a timing belt/water pump replacement. Accessory drive belt + tensioner were replaced as well. Did a 300+ miles trip (highway + mountain road). No issues were noticed. Engine working well. However while parking at the end of the day, became aware of a strange noise coming from the engine bay. Here is how it sounded while idling. https://www.youtube.com/watch?v=_COTs31w5ek As it was too dark, I left further investigation for the next morning. However on the next day everything seemed just normal Let the engine warm up but no sign of the above noise https://www.youtube.com/watch?v=_wJN7T4iLxg Any ideas? |

Problem solved. The bolts that hold the power steering pump pulley had not been properly tightened and were somewhat loose. Beats me why the issue was not evident when idling after a cold start, but the noise appeared after driving for some time. Bolts were tightened, the noise has gone. |

Thanks for letting us know and glad it was benign. Bolts were probably snug and then once warmed up they were loose enough to allow the rattle. |
