Hyundai i20 Crankshafts
We source crankshafts for every i20 generation sold in South Africa, then check the fit against your VIN before it leaves the warehouse
What Are Hyundai i20 Crankshafts?
The crankshaft converts piston motion into rotation — it's the central rotating shaft of every Hyundai engine from the 1.2 Kappa to the 2.0 CRDi. The crank sensor on the snout or bellhousing feeds rpm and position data to the ECU; without it the engine won't start.
Signs You Need New Crankshafts
Before you order crankshafts for a i20
Does one crankshafts listing cover every i20?
No. Ordering crankshafts for a i20 starts with the generation: PB, then GB, then the current BC3.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.
Which engine is in my i20?
SA-market cars were sold with Kappa 1.2, Gamma 1.4 and Kappa 1.0 T-GDi (N Line). The code stamped on the block settles it — the badge on the boot does not.
What do you need from me to quote crankshafts?
The engine code off the block or VIN plate, and whether the car is petrol or CRDi diesel. Hyundai used several engine families in parallel rather than in sequence, so two cars of the same model year can carry completely different internals. The engine code stamped on the block is what a parts desk works from, not the badge on the boot.
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.
i20 Crankshafts: Common Questions
Will crankshafts 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.
Can you source crankshafts for the i20 if local stock is dry?
Usually, yes. The i20 shares its Kappa and Gamma engine families with the Kia Rio, which gives us a second catalogue to search when Hyundai-listed stock runs out. We will tell you what we are quoting rather than leaving you to guess.
Do you mean the crankshaft or the crank sensor?
This is worth settling first, because the two jobs are not remotely comparable. The sensor is a bolt-on part that ages and corrodes; SA retail runs roughly R65 to R550 through our supplier network. The crankshaft itself is an engine-out rebuild. People search for one and need the other more often than you would think.
What does a failing crank sensor do?
The engine cranks but will not start when hot, then fires up again once it has cooled — that hot-stall-then-restart pattern is close to diagnostic on its own. Add random stalling, intermittent misfires and codes P0335 or P0336. On Getz and i20 1.4 CRDi cars, corrosion at the sensor plug is a common cause.
Can I keep driving with a faulty crank sensor?
Not with any confidence — the ECU needs crank position to fire the injectors and ignition, so the engine can cut at any moment. That is a stranding rather than a limp home. Get it done before it picks its own time and place.
What does a crank sensor cost in South Africa?
SA retail runs roughly R65 to R550 depending on model and brand, confirmed across our supplier network, and labour is usually under an hour. Send your VIN rather than the model name — sensor fitment follows the engine family, and a wrong-part return is the most common avoidable delay we see.
What actually kills a crankshaft?
Very little, directly. The crank is one of the toughest components in the engine, so damage to it is nearly always downstream of something else — oil starvation, overheating, or a rod bearing that let go first. If the crank is genuinely damaged, the engine has usually already made the decision for you.
