Changing the Accessory Belt + Rollers (model with air conditioning) on Peugeot 206

Get on a flat surface and prepare a jack, a candle and a cross.

Start by unscrewing the wheel nuts without removing them. The goal here is only to loosen them.

Raise the vehicle using the jack using the lifting points (they are specific). Place the jack stand at the desired height.

For safety, I left the jack at the level of the candle and put the wheel under the vehicle.

Here is the mudguard. It is held by T20 torx screws (in red) and plastic clips (in green)

Here is a plastic clip. Use a flat screwdriver and flat nose pliers to remove them

Here is a T20 torx screw

The operation will be done via the hood. The tensioner roller is circled in green

Using the eye of a 13 key and a 4 pin, you will loosen the automatic tensioner roller to remove the belt.

Here is the roller outside the engine to better see the handling

Using the roller nut as if to unscrew. The whole part will turn and the pin will have to be inserted into the hole next to the arrow (orange square) in order to block the tensioner roller

The belt is now slack. You can remove it

Look carefully at the order. The rollers have a flat surface and the pulleys have grooves.

Depending on whether your car has air conditioning or not. Use the diagram to help you. A = with air conditioning B = without air conditioning. Take only the diagram into account, not the part on the crankshaft

Here we see that the belt had to be changed quickly. For the rollers, turn them and you will notice a pronounced squeak if they are worn. (If they have a lot of KM and years change them)

From there, if you do not want to change the rollers, you simply have to put the new belt back on and re-tension the roller by removing the pin gently so as not to pinch yourself. Then put the mudguard and the wheel back on.

This is the roller.

To loosen it, simply unscrew its nut using a 17 mm wrench.

The tensioner roller has 3 screws of 13 to remove.

We removed the idler roller first because a screw was not accessible

This is what the space looks like once the two pebbles are removed

For the rest, simply proceed in reverse. Replace the new tensioner pulley, then the idler pulley and finally replace the belt. Then re-tighten the tensioner pulley and replace the mudguard and the wheel.

Before replacing the mudguard, start the vehicle to check that everything is fine. The belt should not make any noise. If at the first start there is a small shrill noise for a few seconds, it is simply the belt making its first turn. If this noise continues, STOP everything and check your assembly and your parts.
