Parts for your 2000 Nissan Bluebird-Drive belt tensioner

2000 Nissan Bluebird drive-belt tensioner: is it actually used?

For the 2000 Nissan Bluebird (U14 series), a conventional spring-loaded drive-belt tensioner isn’t fitted. Technical references including the Nissan Bluebird U14 Factory Service Manual (Engine Mechanical and Maintenance sections, 1998–2000 print), the Nissan FAST electronic parts catalogue for U14, and AU/NZ aftermarket catalogues from major belt suppliers indicate the accessory drive uses manually adjusted belts with fixed idler/adjuster hardware rather than an automatic serpentine tensioner unit.

On the SR20DE, SR18DE and CD20-powered U14 Bluebird, the alternator/water pump and power steering typically share one V‑ribbed belt that’s tensioned by moving the alternator along its bracket using an adjuster bolt and then locking it off. The air‑conditioning compressor runs a second belt with its own adjustable idler pulley. Because belt tension is set mechanically via these adjusters, there’s no separate spring-loaded “drive-belt tensioner” assembly to replace.

Why wasn’t a self-tensioning unit used? Nissan’s two‑belt layout on the U14 keeps costs down, is robust, and suits the engines’ accessory packaging. It also makes basic servicing straightforward for workshops and home mechanics: belts are inspected for cracking or glazing, tension is set with the adjuster screw, and the lock bolts are tightened to spec. When noise crops up, it’s usually down to belt wear or an idler/alternator pulley bearing rather than a failed automatic tensioner.

What to watch for on a 2000 Bluebird that doesn’t have an automatic tensioner:

• Cold-start squeal or chirp: often cured by setting belt tension correctly or replacing a worn belt.
• Battery light flicker or heavy steering: a slipping belt may need tension adjustment or replacement.
• Rough/idler pulley noise: the idler or alternator pulley bearing may be due for replacement.

Best practice during servicing is to check belt condition and deflection, spin the idler and alternator pulleys by hand for roughness, and torque the adjuster and lock bolts to the values published in the Nissan U14 service manual. Where belts are aged or noisy even after adjustment, fitting new quality V‑ribbed belts and renewing any rough idler bearings will usually restore quiet, reliable running.

Popular questions

Does the 2000 Nissan Bluebird have a drive-belt tensioner?
It doesn’t use a spring‑loaded automatic tensioner. The U14 Bluebird’s accessory belts are manually tensioned using an adjuster on the alternator bracket and a separate adjustable idler for the A/C belt, as outlined in the Nissan U14 factory service manual and reflected in Nissan FAST parts listings.

How do you adjust the belts on a 2000 Bluebird?
Loosen the relevant lock bolts, turn the adjuster screw to set belt tension, then tighten the lock bolts to spec. The alternator bracket handles the main belt, the A/C belt uses an idler adjuster. Always check belt condition first and recheck tension after a short drive.

What should be replaced if there’s belt squeal?
Start with the belts themselves if they’re cracked, glazed or stretched. If noise persists, inspect the idler and alternator pulley bearings, a rough or wobbly pulley is a good candidate for replacement. Because there’s no automatic tensioner, there’s no spring-loaded unit to fail on this model.
