Parts for your 2016 Nissan Serena-Drive belt

2016 Nissan Serena drive-belt — what it does and how to look after it

The 2016 Nissan Serena does use an auxiliary drive-belt (serpentine belt). Technical references that confirm this include the Nissan Serena C27 Factory Service Manual (EM — Engine Mechanical, HA — Heating & Air Conditioning, PG — Power Generation), which shows the belt, auto-tensioner and routing, plus the Nissan Electronic Parts Catalogue (FAST), which lists the “Drive Belt — Alternator & Air Conditioner” and “Drive Belt Auto-Tensioner.” On S-HYBRID models, the belt also drives the belt-integrated starter generator (the ECO motor), so it’s a critical bit of kit under the bonnet.

On a 2016 Serena, that belt spins the alternator/ISG and A/C compressor, keeping the 12V system charged and the cabin cool. On S-HYBRID versions, it also handles engine restarts and energy recuperation via the starter-generator, so the belt sees higher loads than a typical setup.

Looking after the drive-belt is straightforward and well worth it. A tired belt can squeal on cold start, slip when the A/C kicks in, cause the charge light to flicker, or upset stop–start operation on S-HYBRID models. If it fails, you’ll likely lose charging and A/C straight away.

• Inspection: Have it checked at every service (10,000–15,000 km). Look for cracks, fraying, glazing, missing ribs, or contamination from oil/coolant. Watch the auto-tensioner for wobble or bounce.
• Replacement timing: Many owners replace around 90,000–120,000 km or at 6 years, whichever comes first. For S-HYBRID cars, be a bit more proactive due to the extra load on the belt.
• Quality matters: Use a belt that meets OEM spec and inspect/replace the tensioner and idler pulleys at the same time if they’re noisy or rough.

When it’s time to swap the belt, follow the correct routing (check the under-bonnet decal or the FSM), relieve the auto-tensioner with the appropriate spanner, and ensure the ribs sit squarely in every pulley. After fitting, run the engine and watch for clean tracking and quiet operation. Most workshops will knock this over in about an hour, and it’s relatively inexpensive compared with the headaches a failed belt can cause.

• Does the 2016 Nissan Serena use a timing belt or a chain?
  The MR-series petrol engines in the 2016 Serena use a timing chain inside the engine. That’s separate from the external auxiliary drive-belt, which runs the alternator/ISG and A/C. The chain generally lasts the life of the engine if serviced properly, the drive-belt is a routine service item.
• How often should the drive-belt be replaced?
  Inspect at every service. Many owners plan replacement around 90,000–120,000 km or 6 years. On S-HYBRID models, consider earlier replacement if there’s any noise, glazing or slip because the starter-generator puts more demand on the belt.
• Why does my Serena squeal on cold start?
  Commonly it’s a worn or glazed belt, contamination (coolant/oil), or a weak tensioner. Squeal when the A/C engages or during stop–start points to slip. A new belt and, if needed, a fresh tensioner/idler usually sorts it.
