Citroen Xantia

1. Prop up protivootkatny boots back wheels, поддомкратьте a front of the car and establish it on props. Remove the right forward wheel.

2. In an arch of a wheel remove from a podzor a plastic cover, having provided with that access to the right wall of the power unit.

3. Turning the engine for a bolt of a pulley of a cranked shaft by means of a face natural a suitable drive, attentively examine an auxiliary driving belt on all its length. Pay attention to defects of type of cracks, stratifications and attritions. Existence of zapolirovanny sites to shine is not admissible also. The defective or worn-out belt is subject to replacement.
4. If the condition of a belt is found satisfactory, make adjustment of effort of its tension (except equipped To/in models where the automatic natyazhitel is provided).

1. If yet did not do it, execute the procedures described in "Check", subitem 2 — 3.
2. Disconnect a negative wire from the battery.

3. Weaken fixing and adjusting bolts of an arm of a tension roller (one of fixing bolts is located in the central part of the roller, the second below on an arm).

4. Against the stop tighten an adjusting bolt and remove a belt from pulleys.

5. Check freedom of rotation of a tension roller.

1. In case of need replacement performance, track, that the new belt without fail corresponded on a standard size failed. Throw with a new belt pulleys and choose its weak point as a way of a tightening of an adjusting bolt.
2. Now it is possible to start tension adjustment (see further).

1. If yet did not do it, execute the procedures described in "Check", subitem 2 — 3.
2. Observance of correctness of adjustment of effort of a tension of a driving belt is guarantee of duration of term of its service. The too poorly tense belt usually starts to whistle. Remember also that excessively strong tension of a belt leads to overloads and premature wear of bearings of the generator.
3. The belt should be tense so that at a firm nazhimaniye on it a thumb on a site in the middle between the pulleys most removed from each other the size of a deflection made about 5 mm (see the remark at the beginning of the section).
4. Correction of a tension of a belt is made by rotation of an adjusting bolt. Having achieved satisfactory result, several times turn a cranked shaft, then repeat check. Strongly tighten fixing / adjusting bolts.
5. Connect a negative wire to the battery.
6. Establish into place a plastic cover of a podzor of a wing and the right forward wheel, then lower the car on the earth and tighten wheel bolts.

1. If yet did not do it, execute the procedures described in "Check", subitem 2 — 3.
2. Disconnect a negative wire from the battery.
3. Weaken adjusting/fixing bolts of an arm of a tension roller (one of fixing bolts is located in the central part of the pulley, the second - below on an arm).

4. Turn out an adjusting bolt so that there was a possibility to pass a metal core in an opening in a back part of an arm of a natyazhitel. The end of a core should be bent under 90 °. The main task is fixing of a roller of an automatic natyazhitel at belt replacement.

5. Against the stop tighten a bolt of manual adjustment.
6. Turn out a bolt from the lower part of the To/in compressor and shift aside a plastic cover.
7. Throw off a belt from pulleys (see an illustration the Scheme of laying of a belt of a drive of auxiliary units on the diesel models equipped To/in).
8. Check freedom of rotation of both tension rollers.

1. Make sure that the replaceable belt corresponds failed on the standard size. Throw with a new belt pulleys, having tracked correctness of hit of edges in streams.
2. Turn out a bolt of manual adjustment, having achieved such tension of a belt at which the core can be freely taken from an opening in an arm. After core extraction the demanded tension of a belt will be established automatically.
3. Tighten adjusting/fixing bolts of an arm of a tension roller (do not forget about a bolt located in the central part of a roller).
4. Screw a bolt of fastening of a plastic cover in the lower part of the To/in compressor and strongly tighten it.
5. Connect a negative wire to the battery.
6. Establish into place a plastic cover of a podzor of a wing and the right forward wheel, then lower the car on the earth and tighten wheel bolts with demanded effort.
