Procedure: 2005 XC90 Timing Belt, Water Pump, Serpentine Belt

  1. At 110K miles, the Timing Belt shows very minor hairline cracks. My guess is this TB should last another 30K or so. Ditto for the Serpentine Belt, minor rib cracks but no big deal, it should easily last another 30K. Anyway, I put this Serpentine Belt in the trunk as spare for long trips.—> Serp Belt pulley free-wheels and slightly noisy, glad I replaced it.—> The TB Idler Pulley is still solid, no free-wheeling. The TB tensioner pulley: still OK —> no free-wheeling, but this is the culprit in many forums…when this particular item goes south, there goes your engine.—> The Water Pump bearing is solid, no play at 100K. My experience with my S70, at 145K, slight bearing play but no leak. This WP is known to last 180K-200K easily. Anyway, I am there, I may as well replace it.
  2. A note on TB and VVT system. Do some readings, but the TB does not care about the VVT system, all the TB cares is the relationship between the Crank Sprocket and the Cam Sprockets, as long as this relationship is perfect, you will be fine. The VVT is activated by the solenoids, allowing the cams to be advanced or retarded as needed.
  3. RF Wheel removed, I used 2 Jack Stands: the standard 4-leg Jack Stand and a Screw-Type Jack Stand, this allows me to have 2 Jack Stands for maximum safety and the Screw-Type Jack Stand allows the load to be evenly distributed between 2 Jack Stands.
