Parts for your 1991 Nissan Primera-Timing belt kit

1991 Nissan Primera timing-belt-kit — is it actually used?

Short answer: for most 1991 Nissan Primera models, a timing-belt-kit isn’t relevant because the common petrol engines run a timing chain, not a belt. This isn’t guesswork. Nissan’s P10 factory service manual, plus catalogues from Gates, Dayco and Autodata, all show the GA16DE 1.6 and SR-series petrol engines (SR18DE/SR20DE) using a timing chain. Only the CD20 2.0 diesel variant uses a timing belt that would require a kit.

Why no timing-belt-kit on those petrol models? They’re built with a duplex timing chain that runs inside the engine, lubricated by engine oil. Chains are designed for very long service life and don’t have a scheduled replacement interval like belts do. There’s no “kit” to swap on a timetable. Good oil and filter changes are the main defence against chain and tensioner wear. If the chain system ever gets noisy (especially a cold-start rattle) or there’s evidence of guide/tensioner wear, that’s when a technician investigates and replaces the affected chain components.

• GA16DE 1.6 petrol — timing chain (no timing belt kit)
• SR18DE/SR20DE petrol — timing chain (no timing belt kit)
• CD20 2.0 diesel — timing belt (timing-belt-kit applies)

Got the CD20 diesel? That’s the exception where a timing-belt-kit absolutely matters. The kit typically includes the belt, idler(s), tensioner and often the water pump. Its job is to keep the cam and crank perfectly in sync, if the belt fails or jumps teeth, there’s a real risk of serious engine damage. Most Australian and New Zealand service schedules and parts catalogues suggest replacing the CD20 timing belt around every 100,000 km or 5 years, whichever comes first, and doing the water pump while you’re in there. Use proper locking tools, follow factory torque specs and alignment marks, and always rotate the engine by hand to double-check timing before first start.

For owners of the chain-driven petrol models, it’s still smart to: keep oil changes regular (every 5,000–10,000 km depending on use), listen for chain rattle on cold start, and have any front cover leaks or tensioner concerns looked at promptly. That’s how a 1991 Primera stays cheerful under the bonnet without ever needing a timing-belt-kit.

Popular questions

Does a 1991 Nissan Primera have a timing belt or a chain?
Most petrol versions (GA16DE, SR18DE, SR20DE) have a timing chain. Only the CD20 diesel uses a timing belt that requires a timing-belt-kit. This is supported by the Nissan P10 factory manual and major parts catalogues.

When should the CD20 diesel timing belt be replaced?
A practical local rule is about every 100,000 km or 5 years. Replace the belt, tensioner, idlers and usually the water pump in one go. If there’s any oil or coolant contamination or unusual belt noise, don’t delay.

How can someone tell which engine is in their 1991 Primera?
Check the engine code on the build plate or registration details: GA16DE (1.6), SR18DE/SR20DE (1.8/2.0) are chain-driven petrol engines, CD20 (2.0 diesel) is the belt-driven one. The fuel type is the quick giveaway—diesel means timing belt.
