Parts for your 2000 Nissan Navara-Drive belt tensioner

2000 Nissan Navara drive-belt tensioner: what’s fitted and what’s not

For the 2000 Nissan Navara (D22) sold in Australia and New Zealand, a separate spring‑loaded accessory drive‑belt tensioner isn’t used on the common engines of that year. Instead, belt tension is set manually by adjusting the alternator, power steering pump and A/C idler hardware. This is how the factory intended the belts to be tensioned on the KA24E petrol and the TD27/QD32 diesel variants typically found in model year 2000.

Technical sources back this up. The Nissan Navara D22 Factory Service Manual (1997–2001) in the Maintenance (MA) and Engine Mechanical (EM) sections outlines belt tension checks using deflection/force and specifically instructs loosening the alternator and pump lock bolts and turning adjuster bolts to set belt tension—there’s no mention of an automatic tensioner unit. The Nissan FAST electronic parts catalogue for D22 listings covering KA24E/TD27/QD32 shows no accessory “belt tensioner assembly” for those engines. Major aftermarket catalogues used by trade (e.g., Gates and Dayco Australia/New Zealand) list belts and idlers for these engines but do not list an automatic drive‑belt tensioner for 1997–2001 D22, automatic tensioners begin appearing on later D22 engines (such as YD25/ZD30, introduced after this period).

Why no separate tensioner on a 2000 Navara? The accessory drive uses multiple V‑belts or simple multi‑rib layouts where each accessory provides its own adjustment. This keeps the system robust and easy to service in the field. It does mean owners and techs should check and set belt tension as part of routine servicing rather than relying on a spring‑loaded unit.

• Expect to tension the alternator and power steering belts by loosening their pivot and lock bolts, turning the adjuster to achieve the specified deflection, then re‑tightening to spec.
• The A/C belt typically uses an idler pulley with an adjuster screw, again, set to spec and lock it down.
• Watch for squeal at start‑up, glazing, frayed edges or cracking—signs a belt is loose, misaligned or due for replacement.

If your D22 is a later build with a YD25 or ZD30 (more common post‑2001/2002), it likely does have a spring‑loaded serpentine belt tensioner. But for a 2000 Navara in AU/NZ spec, the drive‑belt “tensioner” as a separate part simply isn’t part of the design.

Popular questions

Does a 2000 Nissan Navara have a drive‑belt tensioner?
Most AU/NZ 2000 D22 Navaras with KA24E petrol or TD27/QD32 diesel engines don’t have a separate spring‑loaded tensioner. Belt tension is manually adjusted via the alternator, power steering pump and A/C idler. Later D22 engines (e.g., YD25/ZD30) did add an automatic tensioner.

How do you tension the belts on a 2000 Navara?
Loosen the relevant accessory’s pivot and lock bolts, turn the adjuster to reach the spec’d deflection (as per the workshop manual), then tighten the bolts. Repeat for each belt (alternator, P/S, A/C). Recheck after a short run in case the belt seats and slackens slightly.

What are signs the belts need attention?
Cold‑start squeal, chirping, glazing, cracking, frayed edges or dim headlights at idle can point to poor belt tension or wear. If the belts are older or contaminated by oil/coolant, replacement is cheap insurance.
