Auxiliary belt urgent help needed please

[moose_eye]

Hi all

I've got 94k mile Clio 172 which recently developed a dodgy noise coming from the engine. I took it to a local garage who told me that
with the auxiliary belt off the noise disappears but put it back on and hey presto its there again. The mechanic said that personally he thought it was one of three things 1) auto tensioner 2) idle pulley or 3)
the water pump. He couldn’t give a definitive answer to which one it was but said he was positive that it was the first two - although in his words this was still a stab in the dark.

I then rang my local Renault dealership and spoke to a technician there who said that if the noise goes when the aux belt is off then its definitely the auto tensioner and pulley that need replacing. He said it had nothing
to do with the water pump as this isn’t controlled by the aux belt.

With this info at hand I thought I’d cracked the problem and could safely get the tensioner and pulley fitted to get rid of the noise. I then found this forum and looked for any similar problems from members. In doing so I came across a post that said the aux belt is related to the water pump.

So my question is can anyone help and tell me which part would need replacing? Would it just be the tensioner and pulley or could it actually be the water pump still?

It would cost me about £300+ to get the tensioner and pulley fitted but if I got that done and the noise was still there I think I’d then have to look at getting a bank loan to pay for a new water pump!! (Considering I’ve just paid out £215 yesterday for some other problems!!)

I would greatly appreciate any help and sorry about the long post. Thank you!!

isit like an electric milk cart noise?
where abouts on the belt isit coming from? if its near the A/C pump then its going to be the idler pulley.
this is the part no. for it:82 00 065 479 TENSIONER ME 42.76 ---3 x 1

If its higher than that, near the spring by the alternator, then its most likely the tensioner.
here is the part no for it: 82 00 226 495 TENSIONER C2 133.30 ---3 x 1

Hope this helps!

hi, just to update

got car back this morning and i'm none the wiser to which part i should replace. the mechanic didnt have the front end off the car when checking the problem so couldnt tell me where abouts the noise was coming from.

the car has now developed a new noise since its been in the garage. in 1st and 2nd gear it now makes a juddering noise up until 2000 rpm if you give it a tinniest bit of welly.

im gettin really fed up with tryin to get this sorted and as i live in the hull area would anyone know of a reliable place to take my car were i wouldnt get charged through the roof and at the same time will be able to get my car repaired?

thanks for the help
