xsara picasso hdi 2L 52 plate - fanbelt issues - marrittm

hi all, i have issue with fanbelt on my xsara picasso hdi 2L, for some reason the fan belt flaps between the crankshaft pully and compressor, i have replaced the following: crankshaft pully+idle guide pully+tensioner (over 12 months ago)+power steering pump+ 3 belts. all the obove have been changed between 12 to 18 months. i took the car to a alternator specialist to check the pully but he said it was ok, i also spoke to citroen specialist and he advised me to try a down size belt to one i have so i did. when i put the downsize belt on the flapping went but the self tensioner vibrates, but after a day it returns to flapping, i have noticed that tho problem is worse when the car is at idle, as soon as you put some revs on the flapping stops but the tensioner still vibrates. could someone please help me with this issue as i cant afford to keep throwing money at this car anymore. i have also notice when the aircon is on the flapping is worse but the aircon works great. at this point im tempted to replace the tensioner as i have checked all ather pullys.

thank you

hi by saying flapping do you mean vibrating? Does your car have got over running type of pulley on alternator ? Just have a look on this link.

Most of the problems which we are facing are alternator free wheel pulleys failures.

hi thanks for reply and good link, when looking at my pully it just looks like a pully with a nut in middle its not as fancy as the ones in link.

Hi there! Did you find the problem at the end? Well I have the same problem mine has an alternator solid pulley as yours, I?think the early ones were like this, my picasso is now at 187k!! Yes not an issue,apart form servicing it. Bought it in uk and moved it to Uruguay, this place is a car hell dusty,hot full of nassive pot holes!, but she still going!!.

The flapping belt problem is been there from the 110k replacing belts time to time tensioners,Idler,crank pulley, at the end the alternator pulley which was alloy was worn out,and the belt was slipping always at idle a lot, today foud a new similar pulley from a 206 wich I had to shim up to align with the belt! (Cant!get just the pulley over here!) Right stopped slipping but the flapping returned with!the horrible tensioner rumbling, worse when cold!.

So I am a car mechanic I have a workshop, once I modified an old automatic tensioner, to make it fixed, and using a shorter belt than the stock 6pk1740, managed to get it tight using the manual tensioner at the bottom, fine for 2 days then the belt started falling apart!!.

So bought a new original tensioner still the same, again it gets worse when cold under and under more electrical load,alternator charges at 14.something spins with no play no drag,bearings are ok, so still as yours just the alternator to try, and!the batery.

for some reason this batery has 8 years!! Still starting at the flick of the key, it might take more power to charge it and that could be the problem? Is a euro ac delco, over here Im fitting the brazil ac delco ones to my customers and only last 3 years!

Any help will be apreciated thanks!!!
