Parts for your 2000 Nissan Bluebird-Drive belt pulley

2000 Nissan Bluebird drive-belt pulley: purpose, care, and when to replace

Technical documentation confirms a drive-belt pulley is absolutely fitted to the 2000 Nissan Bluebird (U14 series). The Nissan Bluebird U14 Factory Service Manual (sections MA and EM), the Nissan FAST electronic parts catalogue, and the SR-series engine FSMs show V‑ribbed accessory belts driving the alternator, power steering pump, and A/C via the crankshaft pulley (harmonic balancer), plus idler/tensioner pulleys. So the drive-belt pulley is relevant to this model.

On this Bluebird, the accessory drive relies on a set of pulleys to transfer engine rotation to the alternator, power steering pump, and A/C compressor. The crankshaft pulley—often called the harmonic balancer—does the heavy lifting, while the alternator, A/C and power steering pulleys follow along. Idler and tensioner pulleys keep the belt(s) guided and at the right tension. Without this lot spinning happily, the battery won’t charge, steering gets heavy, and the cabin won’t get cool.

Most 2000 Bluebirds (U14) with SR18DE/SR20DE or CD20 engines run separate V‑ribbed belts: typically one for the alternator/water pump, one for power steering, and one for A/C. Tension is set with adjusters on the alternator and power steering brackets, and the A/C usually uses an adjustable idler pulley. Every pulley should spin freely with no rumble, wobble, or play. The crank pulley has a bonded rubber damper, if that rubber cracks or the outer ring “walks”, it’s time for a new one.

Servicing is straightforward. Inspect belts and pulleys at each service or every 10–15,000 kilometres. Watch for cracking, glazing, frayed edges, black dust, and any squeal or chirp. Check pulley alignment and listen for bearing noise. If a pulley feels gritty, is noisy, or shows wobble, replace it and fit a fresh belt. Skip belt dressings—they only hide issues. After fitting a belt, set tension to the Nissan spec and recheck after 500–1,000 kilometres as the belt beds in.

Replacement tips: disconnect the battery, crack the pivot and lock bolts, then wind back the adjuster to slacken the belt. For the A/C belt, back off the idler adjuster. Route the new belt correctly, ensuring all ribs sit square, then tension and torque hardware to the factory specifications in the service manual. If the harmonic balancer looks tired, replace it as an assembly and inspect the keyway and front seal while you’re under the bonnet.

Done right, the Bluebird’s accessory drive will run quiet for years, keeping charging spot-on, steering light, and A/C frosty—no dramas.

Popular questions about 2000 Nissan Bluebird drive-belt pulleys

Which pulleys does the 2000 Bluebird use?
This model typically runs a crankshaft pulley (harmonic balancer), alternator pulley, power steering pump pulley, A/C compressor pulley, and one or more idler/tensioner pulleys. Belt layout and adjusters can vary slightly by engine variant, but the setup is broadly the same across SR18DE/SR20DE and CD20 models.

How often should belts and pulleys be replaced?
Inspect them every service or 10–15,000 kilometres. Belts are commonly replaced around 60–100,000 kilometres or sooner if noisy or cracked. Pulleys usually last longer, but any bearing noise, roughness, or wobble means replacement is due. Always check the crank pulley’s rubber damper for separation.

What causes belt squeal on cold start?
Usually low belt tension or a glazed belt, but a rough or misaligned pulley can do it too. A quick spritz of water on the ribbed side that briefly quietens the noise points to the belt/tension. Persistent noise even with correct tension suggests a failing pulley bearing or alignment issue.
