Aux belt tensioner on a 2.2

[gumby6371]

I noticed a noise coming from the aux belt area last night, quite pronounced when the engine is warm but only a slight whine when cold.
My mate and I tracked it down to the tensioner so I'll be swapping it at the weekend amongst other jobs in the engine bay.

Looks to me a straight forward enough job but any tips/hints on changing them on the DW12 or pit falls to avoid?

Thanks in advance as always

Top man Jon,

As usual 2 minutes to change 30 minute faff to get at it!!!!

Funnily enough ECP has a couple of crank shaft pulleys listed and they are heavily discounted at the minute £50 to £90 for OE quality (there claim not mine).
The pics dont look like the one in the guide but it could be stock photos, I think I'll change the tensioner and have a good nosey at the pulley while I'm there and grab one if needed while they're cheap.

I just rang my LMF and he's got a Gates tensioner on the shelf for £37 which he's holding for me.
Out of curiosity I rang the stealers, not in stock but can be overnighted if I want it for an extra £5, tensioner cost £92.
He sounded a little put out when I asked if you got the rest of the car with it

The OEM pulleys were either Dayco or Corteco depending on who you ask, maybe they both manufactured them.

They updated the pulley design due to them all failing, I believe the new design from Pug have three slots around the circumference rather than 2 on the factory fitted units.

I've also heard that some of the replacement pulleys have no slots due to being a completely different design altogether.

Mine's going to need changing soon and I'm determined to get either a Dayco or Corteco, but I'm not paying £150 from a dealer. But I do want to make sure it's not going to fall apart again in 3 years!

I put Gates everything, (including aux belt tensioner on your estate at about 165/170k if memory serves). Pretty sure it was about £40 (and needless to say you couldn't fault the original).

Interesting, thanks for that. Maybe I'll whack a Gates one on there and see how it goes then, the estate's crank pulley is still fine and it's on about 215k now

The pulleys on ECP have no slots but as I said could be a stock picture, so the concensus is shop for a better brand then?

[jonsowman]

The reason I was going on about Dayco/Corteco is that I've heard of so many of the cheap no-brand ones failing after 2-3 years.

So best to get a known good brand, and Gates appears to also be fine

[gumby6371]

Curiously the new tensioner I fitted (thanks Jon for the guide) was branded as Gates on the box but stamped on the actual part as Dayco.

This can mean either Gates are a manufacturer/distributor or my LMF put it in the wrong box.
Either way it would appear to be an OE quality part so I'm not bothered either way!

Excellent, that's a result then. Glad it's all sorted!
