After living with banshee squealing under the hood, have replaced belt (twice with x2 different makes) and auto tensioner, my TD5 still squeals. Have tried WD40, Belt dressing, the only thing I can find, is a longitudinal movement (front to back) on the A.CE. Pump of @ 5mm,is this normal ? . At £300 a shot for the new pump, I could do with any advice.
Thanks.
Before you spend anymore money, have a thinking about trying this fix, it works on Tdi 300 so it might work on yours as well:
1. Bend back the tensioner with a spanner on the idler wheel bolt, then take the belt off it;
2. Slacken off the idler fixing retaining bolt until you can get a 1 penny piece,
yes, I know, it sounds crap doesn't it?, then slide the penny between the engine block and the tensioner, at 9 o' clock;
3 Refasten the tensioner bolt and start the engine.
I was very sceptical about this when I first heard it because it sounds like rubbish doesn't - the really inconvenient thing is, however,
that it has worked on literally hundreds of Tdi 300 engined vehicles.
What have you got to lose - it only takes a couple of minutes.
When my car was doing canary impressions, I bought a new tensioner assy at a cost of about £60, so I thought before I put this new bit on, I'll just try the penny trick.
That was 3 months ago, not a squeak since.
