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
