Vibrating Noise From Auxiliary Belt

[Guest kenc5]

C5 HDI 2.0 HDI SX 2002 52REG I have a vibrating noise coming from auxillary belt, have had replacement bottom pulley+roller+tensioner by dealer. Tensioner still jumping about which i think is the vibrating noise have been told by dealer it could be air con compressor causing it but wont guarantee its that ,only noisy at idle speed raise the revs by about 3 hundred and noise and jumping stops.Has any one had the same problem or any idea of the cause.

I have a 52 plate 2.0 HDI with exactly the same problemand can't get to the bottom of it, was about to change the crank pulley but the one I bought looks wrong, I have suspected the aircon pump as there seems to be play in the bearings. Cars only done 52000!!!!!!!!!!!!!!!

i too have the same problem, had the pulleys and water pump changed last december, last week the car developed knocking noise in the area of the belts, the garage that fixed it said it was something to do with the wrong idle speed but i dont really believe that, he also said that nothing was wrong and the noise was "normal" well i dont call a vibrating noise that wasnt there before normal, i am going for a second opinion tommorrow so will keep you posted !

If any of you are having a a problem of a noisy auxillary drive belt/tensioner jumping about, you will find the problem is a siezed "freewheel pulley" on your alternator. A lot of cars are now being fitted with these pulleys, designed for smoother running and of course being another service item which will cost us a small fortune to diagnose and replace. When the freewheel siezes the belt gathers up behind pulley making a right clatter and shredding the drive belt

I was going to replace one on my 1999 Ford Galaxy 1.9TDI and managed to find a local Bosche Specialist who would fit it for me if i purchased it (about £35) from him (surprise, surprise you need a special splined tool to remove pulley!) The alternator took so long to manouver out of the car i decided to check the brushes and ended up replacing the alternator which came with pulley for about £185. You will need to replace drive belt which shreds up quickly under these conditions. I have checked my2004 C5 2.0 HDI 110 and surprise surprise there is one fitted to mine!

There is a chap on the Ford Galaxy forum called littledaz who thankfully has enlightened everybody as to the existence of this pulley so you can thank him for this advice

Well the noise is still there, it hasnt got any worse but i am taking it to a diesel engine specialist in Cannock i have been told about, the other opinion i got was from a local garage, they wouldnt touch the engine !, but he did say he has heard the same noise coming from c5's he has mot'd recently, oh joy !

Please see my previous post - the noise & vibration is probably caused by a siezed freewheel pulley on your alternator. the valeo alternator on my 2004 2.0hdi 110 is fitted with one. the way to check it is to try and turn the cooling blades with a small screwdriver ( might be best if you disconnect alternator first)

you can just about see these blades through the slots furthest away from the pulley. They should be able to turn one way but not the other. if they can't be turned either way, your freewheel pulley is siezed and will need to be replaced

I had exactly the same problem with my 2.0HDI and you will find probably find that the problem is the crankshaft pully driving the auxillary belt. The symptoms are a bit misleading because it appears that the tensioner is jumping about , causing the rattling, but in fact the crankshaft pulley is a two piece unit with a pulley within a pulley (for the want of a better description) which is designed to absorb vibraton and make the engine smoother. When this becomes faulty, it tightens / slips and the end result is that the auxillary belt alternates between tight and loose, the tensioner gets loaded / unloaded, and quite probably the auxillary belt gets cracked or shredded.

Be warned that if the engine is run for any length of time in this condition it can lead to the timing belt breaking, due to the constant under heavy load / no load scenario.

Well i took my c5 to the diesel "specialist", he changed the large bottom pulley (dont know the proper name for it), the noise went away for about 20 miles but now an irritating knocking noise has appeared, sounding like knocking tappets, the garage that did the work phoned his mate at a citroen dealers who said it was the alternator (as mentioned in previous post) , apparently they have been modified now with a type of clutch to compensate for the pulleys and belts (sorry about the non technical explanation), this alternator will cost me £125 plus vat and he reckons he might also have to change the bottom pulley as well as it may be the wrong one !!!, this is really doing my head in !, does anyone know of a decent mechanic in the B'ham area ? i am fed up of throwing money at this car !!!.

[andyl56]

Just an update, the alternator cost me £125 plus vat, the garage in cannock fitted it for nothing as i was having so much trouble, touch wood the rattling and tractor noises have gone , will let you know if the come back (please no!!), the mechanic showed me this alternator which doesnt spin freely like the old one did, it has some mechanism that stops it rotating after you try to spin it round, this doesnt make sense to me but the noise has now totally gone, now for those squeaking brakes !!!!.

have a close look at your alternator pulley. It is a free wheel pulley and will wear out and wobble stick generaly wreck your auxillary drive belt and make all those rattle noises at start up and idle.

 

When i had gone through my 3rd belt in 3 years I checked all the pullys with the plan of changing the tensioner again, but no its the alternator..

 

the alternator is £200,00 but the pulley and the tool to remove it with is only £70.00.

 

got mine from local motor factors through hc CAR-GO parts suppliers

dont believe the garage crap about needing new alternator just the pulley will do the job

I'm having exactly the same problem with my C5.

 

I need to get a Veleo CL15 pulley to fix the alternator.

 

All Citroen want to do here is sell me a new alternator at around $1800 AUD

 

They say they can't supply the part, and Valeo in Australia can't or won't supply the pulley part either.

 

Does any forum member know of any UK web site where I can order a Valeo Pulley for the alternator?

 

Any assistance would be gratefully received

 

Cheers

 

Graham

[bago]

Can anyone assist?

 

Can anyone recommend UK spare parts suppliers?

 

If not, I'll just Google and try myself

 

Thanks

you can look here

http://cgi.ebay.co.uk/Crank-Shaft-Pulley-F...p3286.m14.l1318

 

to be honest i had a pulley fitted and the noise was the same !, onlly went away when i had an alternator fitted

Thank you for that Andy

 

I don't really want a new crankshaft pulley - There are two types of pulleys fitted to the 2002 C5's. One has one rubber damper built in and the oher has two rubber dampers built in.

 

My Citroen dealer says I have the former type of pulley and that replacing it with the latter type will fix the problem. The fix is an unpleasant $800 AUD

 

I need a new alternator pulley - not a new alternator as the dealer claims.

 

So that's what I am looking for Valeo CL15 alternator. I have an auto electrician who says that can fit a new pulley and fix the noise problem.

 

Can't get one in Australia but by reading your forum I might be able to get one in the UK if I can find a good UK spare parts website.

 

Thanking you

sorry, you said alternator pulley, this is the pulley that is physically attached to the alternator ?, all i can say is that i had the crankshaft pulley and another tensioner pulley changed and the noise and banging only went after i had an alternator fitted !, oh the joys of citroen c5's !!!

[gehngus]

Hi all.

I have had the same problem. tractor noises etc and was told by mechanic to  "ignore it, probably the engine mounts rattling".

 

Now the belt is jumping and the tensioner wheel is loose and i have a squeeling noise.

 

I have to find a new belt and tensioner set, but reading this i might be just as well looking for this alternator as well.

 

Just so i dont get the problematic alternator again, does any one know if the part numbers differ for each and which is the correct alternator (or pulley as i have extraction tools) i should be getting.

 

So far im having a nightmare just getting suppliers to confirm which pulleys i need to go with the belt. i would like to get the lot from one place if posible.

 

does anyone have a supplier who could give a decent answer?

 

The car is a 2003 Citroen c5 sx hdi 2.0 (1997cc)
rc code DCRHZB
VIN VF7DCRHZB76309617
REG .
car has SANDON compressor.

 

many thanks.

For security reasons I have deleted your car reg no. since the vin is also there.

 

The Citroen alternator part no is 5705 AA for a new one and 5705 ER  for an exchange one. Either could be Bosch or Delphi but are 150 amp. The parts do not list a separate pulley. There are also different Bosch part numbers possible.

Thanks for removing info. didnt occur to me.

I have found an Alternator Clutch Pulley product number ZEN 5437 which fits the 5705AA.

 

i will register on the service.citroen site now.

 

many thanks

Just to confirm the above. Although it looked like a tensioner it was indeed a seezed alternator pulley.
