Evening team!
As the subject title says my 3500s has recently started to squeak like mad at idle. This is coming from the PAS pump or belt. The belt is maybe 6 months old, and was a Dayco one i think.
The temperature of the engine bay doesnt seem to have any effect, it does it at any time during my commute - but as soon as the revs pick up past idle it stops.
This evening I went and checked the alignment of the pulleys and they were slightly out. I therefore undid the bolts that secure the bracket to the timing chest/block and slipped a couple of washers behind them to get things lined up better.
Went for a test drive and after 10 mins it was the same!
Any suggestions on what to do next? Not sure I have the belt tight enough, was aiming for the 6-9mm the book states but i remember the old belt seeming to have more tension in it.
Would this cause such a noise at idle?
thanks!
