Removing, installing and tensioning the V-belt

The engines are equipped with wide V-belts. Compared to traditional belts, Mondeo's belts have a longer service life, and more than one machine can be driven with a single belt. When laying the V-belt, make sure that it is not misaligned on all belt pulleys. During regular inspections, the V-belt must be checked for wear and defects. If the side surfaces of the belt are frayed, cracks or breaks appear on it, then it must be changed.

Belt replacement

Unscrew the wheel arch trim -1-. Unscrew the protective cover of the V-belt.

Four-cylinder petrol engine

The V-belt drives all auxiliary units. The belt is tensioned automatically by the tension roller. The figure below shows the layout and operation of the belt.






Press the tension roller with a wrench, counteracting the force of the spring - arrow. As a result, tension is removed from the roller. Remove the V-belt.

To lay the V-belt, press the tension roller in the direction of the arrow.

Install and screw on the protective covers.

Diesel engine

Auxiliary units are driven by separate V-belts. Belt tension can be adjusted using the tension bolts.





Alternator V-belt: Loosen the central nut -3- of the tensioning roller, but do not unscrew it. Loosen bolt -1- and remove V-belt.


Lay a new V-belt, fix the tension roller with the bolt -1-.

Check the V-belt tension at point -2- between the alternator and the crankshaft pulley. When pressed with your thumb, the new V-belt should sag no more than 2 mm. A used V-belt should not bend more than 4 mm.

Finally, tighten the central bolt of the tensioning roller -3- to 24 Nm.

Power steering pump V-belt: unscrew the bolt -1- and remove the cover.



Slightly loosen the bearing bolt -2- of the oil pump, but do not unscrew it.



Loosen the bearing bolts -1- on the power steering pump and -3- on the tensioner, but do not unscrew them. Release the bolt -2- and remove the V-belt.

Lay a new V-belt and tighten the bolt -2-. When pressing with your thumb on the V-belt, it should sag no more than 1 mm.


Tighten the bearing bolts on the power steering pump and tensioner to 25 Nm.

Screw on the protective cover of the belt with two bolts.



A/C compressor V-belt: Loosen clamping bolt -1- and remove V-belt -2-.

Lay a new V-belt and tighten it with the bolt -1-. When pressing on the belt with your thumb, it should sag no more than 2 mm.
