Matthias Sammer Posted March 17, 2012 Report Share Posted March 17, 2012 I know there is a few threads on how to replace them but just wondering how long they are supposed to last (2004 Gen 7 TSport). I think mine was replaced when I had it serviced at ~70K miles back in Aug 2010. Now on 83k miles. Had another service was at ~80k in Oct 2011 when car got a clean bill of health. Serviced by ToyodaTech (Toyota specilaists) so although I don't know what brand belt they used I would have thought they'd use something decent. The whining started a few weeks ago and persists even when the engine is warmed up. Link to comment Share on other sites More sharing options...
ams Posted March 18, 2012 Report Share Posted March 18, 2012 Could be tensioner, 80-100k is about the life of the Aux belt. Get a torch and see if the rubber on the toothed side has started to crack Link to comment Share on other sites More sharing options...
Bumblebee Posted March 18, 2012 Report Share Posted March 18, 2012 i have had to replace mine approx every 18 months over the last 6 years due to being noisy Link to comment Share on other sites More sharing options...

Get a torch and see if the rubber on the toothed side has started to crack Seems perfectly, as good as new even I would say. But there is a bit of slack in the belt, so maybe it just needs tightening? Link to comment Share on other sites More sharing options...
Bumblebee Posted March 22, 2012 Report Share Posted March 22, 2012 it is self tensioning , you cant adjust it Link to comment Share on other sites More sharing options...
Matthias Sammer Posted March 22, 2012 Author Report Share Posted March 22, 2012 I see, does that mean tensioner most likely needs replacing? Link to comment Share on other sites More sharing options...
armoredfist2002 Posted March 22, 2012 Report Share Posted March 22, 2012 belt is the cheapest to replace, so I would change that first, you can get them for around £20 and fit yourself, if it's still noisy afterwards then look at the tensioner, plus you have a new belt to go with the tensioner if it does need changing Link to comment Share on other sites More sharing options...
Matthias Sammer Posted March 28, 2012 Author Report Share Posted March 28, 2012 Local garage had a look today (free of charge) at the belt and tensioner using a stethoscope but couldn't diagnose the fault for sure. They offerred to replace the tensioner @£170 + 1h labour but couldn't guarantee that would solve the whining. Sometimes it's there, sometimes not, and no correlation with engine temperature or distance driven. Obviously this is outrageous for the part as I've seen them for £100 and less new but credit to them, they said I was more than welcome to source a second hand one to try. SO I'm thinking of doing that - get another new belt and second hand tensioner off here or Ebay and replace the existing. In the meantime, any risk of damage as I need to use the car and I don't think I'd get anything done till next week? Link to comment Share on other sites More sharing options...
