Replacing drive belts (Mondeo 3)

In Mondeo engines, an automatic belt tensioner keeps the poly V-belts in a tensioned state. So you don"t have to worry about belt tension any more. However, the pressure rollers should be inspected from time to time. If you don"t notice anything unusual in the "resting state", then start the engine and pay attention to the movement of the pressure roller: if you turn on a "major consumer", such as the air conditioner, rear window heating, etc., then a serviceable roller "swings" slightly – however, even when the engine is given a strong "gas push". Severe wear of the belts (unevenly deep grooves) constantly encourages the pressure roller to oscillate. To eliminate these deficiencies, first replace the drive belt. Make sure that the new belt has the same specification as the old one.

Below this work is described using the example of the Duratec-HE engine.

ORDER OF EXECUTION

Set the handbrake and securely raise the front of the car with a jack. Remove the front drive belt guard. Loosen roller 7 and... ...remove the worn belt. Check all belt pulleys for wear and proper rotation. Place the new belt in the pulleys and tighten the clamping screw on the pressure roller securely (approx. 5–6 N·m). Winding roads: the drive belt in the Duratec-HE engine. 1 - Generator, 2 - Swivel roller, 3 — Power steering pump, 4 - Water pump, 5 - AC compressor, 6 — Crankshaft torsional vibration damper, 7 - Automatic belt tensioner. Modification: belt drive of the "new" Duratec-VE. 1 - Generator, 2 — Power steering pump, 3 - Automatic belt tensioner 4 - AC compressor, 5 — Crankshaft torsional vibration damper. With two swivel rollers: DuraTorg-DI belt drive. 1 - Swivel roller, 2 - Belt tensioner, 3 - Swivel roller, 4 - AC compressor, 5 - Drive belt, 6 — Crankshaft torsional vibration damper, 7 — Generator. Camshaft driven power steering pump. 1 - Belt tensioner, 2 — Camshaft, 3 - Drive belt, 4 — Power steering pump.
