XUD slipping accessory belt - David Horn
Had the belts changed on my 1.9DT Xsara a few months back - now there's a bit of squealing when load is put on the power steering when cold.

Is it easy enough to tension the belt myself? Kinda difficult to drop back into the garage as I'm 300 miles away.

Cheers,

David.

The main problem is usually getting access to the adjusters with arms of a normal size and length. If they are multi-groove belts then they operate at higher tension than single-vee belts. Apart from that, you should be able to tension them yourself. Does the owner's manual give details of belt tension? On most Japanese cars there are stickers on the underside of the bonnet that give diagrams of belt tension etc, perhaps this is so for... is XUD a Peugeot?

Well, belts do squeal, but probably not that much.

The belt should feel very tight.

With the bonet up and the engine running turn the steering to full lock. If the belt is very loose then when you hit full lock you might be able to see it slipping on the top pulley.

The belt is tensioned by a sprung pulley running on the back of the belt. This pulley is pulled upwards and locked in order to change the belt. It seems that they do not always return as far as they should, resulting in a slack belt. Returning the pulley seems to be a case of playing with it (pulling it part way up and easing it back down) until it drops all the way down and tensions the belt properly.

This belt drives the alternator, power steering pump, and air conditioning compressor. You should be able to limp home without it.

There are several different layouts of XUDT acc belts, depending on the age of the car, and the accessories fitted. In principle they are all tensioned the same though I think. You will need to jack up remove the driver's side wheel and wing liner. You should now be able to see the crank pulley, acc belt, and tensioner in front of the crank pulley - a large idler wheel with an arm pointing downwards. There are two bolts holding the tensioner on - one on the arm, one in the centre of the pulley (they're allen screws unfortunately!). Slacken the screws off then wind out the adjuster screw at the bottom of the arms to tighten the belt - it should go OK since its been disturbed recently.
