Hyundai i20 Timing Chains
Whether your i20 is an early or late build, we match the timing chains to your derivative rather than to the badge

What Are Hyundai i20 Timing Chains?
The timing chain synchronises the crankshaft and camshaft so the valves open at the right moment. On Hyundai 1.6 T-GDi Gamma petrol and 1.5 CRDi diesel engines we see chain stretch well below 100,000km — a cold-start rattle from the front of the engine is the defining warning sign and needs acting on fast.

How we match timing chains to your i20
What changes across the range
On the i20, PB, then GB, then the current BC3 are all in circulation locally, and they do not share one parts list.
The PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it.
Worth knowing: the i20shares its Kappa and Gamma engine families with the Kia Rio.
What we check on timing chains
- •The generation code, because i20 parts lists split on it
- •The engine family — this i20 was sold with Kappa 1.2, Gamma 1.4 and Kappa 1.0 T-GDi (N Line)
- •The engine code off the block or VIN plate, and whether the car is petrol or CRDi diesel
- •Whether the car is pre- or post-facelift within its generation
In South Africa the i20 is mostly a high-mileage commuter hatch that spends its life in stop-start city traffic, which is why wear items move faster on an i20 than on almost anything else Hyundai sells here. That is the wear pattern we stock and source against.
Before You Order i20 Timing Chains
Will timing chains from another i20 fit mine?
Not automatically. The i20 sold in South Africa as PB, then GB, then the current BC3, and the PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
How do you check timing chains actually fits a i20?
We work backwards from the VIN: generation first, then engine family, then whether the car is pre- or post-facelift within that generation. On the i20 specifically, the PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it.
Why does my Hyundai rattle on cold start?
On 1.6 T-GDi Gamma and 1.5 CRDi engines, a 1-3 second rattle from the front of the engine on cold start is textbook timing chain stretch. Don't ignore it — the longer it runs, the higher the risk of chain jump and bent valves. Book a diagnostic immediately.
How much does a Hyundai timing chain replacement cost?
It's a major job involving the chain, guides, tensioner and usually the sprockets. SA workshops quote by model and engine. Request a free quote through our form with your engine code for accurate local pricing.
Which Hyundai engines have timing chain problems?
The 1.6 T-GDi Gamma petrol (i20 N, i30 N, Creta, Santa Fe) and 1.5 CRDi diesel (i20, Tucson, Accent, Creta, Santa Fe) are known for early chain stretch. The 1.6 MPi petrol is less prone but still susceptible if oil changes are skipped or wrong grade is used.
Can a stretched Hyundai timing chain cause engine damage?
Yes — a badly stretched chain eventually jumps teeth, the valves hit the pistons and you're looking at bent valves or a complete engine rebuild. At the first persistent cold-start rattle, stop driving and book it in. Cheaper to fix early than rebuild.
How often should a Hyundai timing chain be replaced?
Manufacturer says 'lifetime of the engine' but real-world 1.6 T-GDi and 1.5 CRDi engines see chain stretch from as early as 50,000 to 80,000km. We recommend inspection at 80,000km regardless and immediate action on any cold-start rattle, whatever the mileage.
What oil should I use to prevent timing chain stretch?
Hyundai/API SN 5W-30 full synthetic is the specified grade for 1.6 T-GDi engines and matters more than any other service item. Use exactly that spec, change every 10,000km maximum, never stretch the interval. Wrong oil is the single biggest cause of early chain failure.

Let us confirm the timing chains before you buy
Photos of the old part and your VIN are usually all we need. We confirm the timing chains against your i20 before quoting, not after.
