Parts for your 2010 Ford Falcon-Drive belt pulley

2010 Ford Falcon drive-belt-pulley — what it does and how to look after it

Yes, a drive-belt-pulley is absolutely relevant on the 2010 Ford Falcon. Technical references back it up: the Ford FG Falcon Workshop Manual (Section 303-05, Accessory Drive) shows a single serpentine belt running across the crankshaft pulley (harmonic balancer), alternator, A/C compressor and power steering pump, guided by an automatic tensioner and idler pulleys on both the 4.0L Barra inline-six (including XR6 Turbo and LPG E-Gas) and the 5.4L Boss V8 where fitted in 2010. Major aftermarket catalogues for Australia and New Zealand (Gates DriveAlign and Dayco) also list specific tensioner and idler pulleys for the 2010 FG Falcon range, confirming fitment.

On this Falcon, the drive-belt-pulley system transfers engine torque from the crank to the accessories so you get charging, cooling, A/C and steering assist. The crank pulley/harmonic balancer damps vibrations, the idlers keep the belt tracking true, and the spring-loaded tensioner maintains the correct belt load as revs and temperature change. When the pulleys or belt wear, the spin gets noisy, the belt can slip, and under-bonnet temps can climb fast.

As part of regular servicing, it’s smart to inspect the belt and pulleys every 15,000 km or at each service. Under the bonnet, look and listen for:

• Chirps, squeals or rumbling that change with engine speed.
• Belt glazing, cracks, missing ribs or frayed edges.
• Pulley wobble, visible runout or rubber delamination on the harmonic balancer.
• A tensioner that’s bouncing or sitting off its index marks.

Many workshops in AU/NZ replace the belt, tensioner and idler pulleys as a set around 100,000–120,000 km, or sooner if there’s noise or dust ingress from rural roads. On the Barra I6, the water pump is belt-driven, so a tossed belt can quickly lead to overheating, don’t ignore grinding or wobble. If the harmonic balancer shows any cracks or the outer ring creeps, replace it promptly.

When fitting, follow the belt routing decal in the engine bay or the workshop manual, use the square drive on the tensioner to relieve load, and spin each pulley by hand to feel for rough bearings. A quality belt and OE-equivalent pulleys will handle Aussie and Kiwi heat better. Always match parts to VIN/engine code, as FG I6 and V8 pulley layouts differ.

Does a 2010 Ford Falcon actually have a drive-belt pulley?
Yes. The FG-series Falcon (2010) uses a serpentine accessory drive with a crank pulley/harmonic balancer, idlers and an automatic tensioner across I6 and V8 variants. Ford’s workshop manual and AU/NZ parts catalogues list these pulleys for the model.

What are the signs a drive-belt-pulley is failing on a 2010 Falcon?
Listen for chirping or rumbling, watch for belt wander, and check for pulley wobble. Charging or A/C underperformance, intermittent power steering assist, or rubber debris around the balancer are also common clues.

Should the belt and pulleys be replaced together?
It’s good practice to replace the belt, tensioner and idler pulleys as a kit, especially past 100,000 km. Fresh bearings and correct tension help the new belt last longer and reduce the chance of a roadside drama.
