    Default 1.9cdti (120) Squeal under load

    I'm hoping someone out there may be able to shed some light on a problem that i am having. When i put the car under load, for example third gear at 1400 if i put my foot down i get a loud squealing / whining noise. This happens in any gear trying to pick up from low revs, I sometimes get the noise when accelerating hard up to 3500rpm-4000rpm although i rarely do this.

    Slipping aux belt? The part is about a tenner, unsure of the work involved on a 120bhp but the 150 can be done in about half an hour - hour

    Just a heads up on this problem.

    You are not "loading" the engine but "labouring" it in that low rev range, the tensioner pulley is jumping around and cant cope with the strain.

    Also/due to >>>>

    Make sure the engine under panel is still fitted to the car.

    Its a plastic under tray covering the bottom of the engine and the aux belt run.
    if this is not fitted replacing the tensioner and aux belt is pointless as it will squeal due to the road dirt grime as its unprotected.

    You can buy a spray can of silicone belt lube to keep things quiet for a few weeks depending on road conditions.
