Hyundai i10 Radiator Caps
Radiator Caps to suit the Hyundai i10, cross-referenced against OEM specification and dispatched countrywide
What Are Hyundai i10 Radiator Caps?
The radiator cap is the pressurised seal on top of the expansion tank that holds coolant in the system and sets the boiling point. Caps are rated to a specific system pressure, and one that physically fits is not automatically the right rating — that is the thing to check when replacing one. We see caps lose their spring tension and cause overheating and weep.

i10 Radiator Caps: what actually decides fitment
The i10 reached South Africa as PA, then the Grand i10 BA, then AI3, and that alone changes what fits.The original PA i10 and the later Grand i10 are separate platforms with separate parts catalogues — "i10" on its own is not enough to order from.
- 1
Find the generation code on your i10 — it appears on the VIN plate and on the original registration paperwork.
- 2
Confirm the engine family. The i10 ran Epsilon 1.1 (PA), Kappa 1.25 (Grand i10) and Kappa 1.2 (AI3) in this market.

Send both to us with the radiator caps you are after , along with petrol or diesel, and whether the car has air conditioning. We match it before we quote, not after.
Sourcing note: the i10shares the Kappa petrol family with the Kia Picanto — which widens where we can look when local stock is thin.
In South Africa the i10 is mostly first cars, driving-school fleets and short-hop city work, so components see far more cold starts per thousand kilometres than the odometer suggests. That is the wear pattern we stock and source against.
Hyundai i10 Radiator Caps — Questions We Get Asked
Will radiator caps from another i10 fit mine?
Not automatically. The i10 sold in South Africa as PA, then the Grand i10 BA, then AI3, and the original PA i10 and the later Grand i10 are separate platforms with separate parts catalogues — "i10" on its own is not enough to order from. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
Which engines did the South African i10 come with?
SA-market cars ran Epsilon 1.1 (PA), Kappa 1.25 (Grand i10), Kappa 1.2 (AI3). The code stamped on the block is what we work from — the badge on the boot is not reliable on its own.
How much does a Hyundai radiator cap cost in South Africa?
A Hyundai-spec radiator cap runs around R149.99 through our supplier network, which also carries alternatives. Fitted is a two-minute job, so budget well under R250 all in.
What are the symptoms of a bad Hyundai radiator cap?
Rising temperature gauge, hissing from the coolant tank, steam from the bonnet and coolant drops with no visible hose leak are the usual signs. Always replace the cap before stripping hoses or the radiator itself.
Can a faulty radiator cap cause a Hyundai to overheat?
Yes. A cap that cannot hold full system pressure drops the coolant boiling point, so fluid steams away at the expansion tank in traffic. The needle climbs fast and the engine risks head-gasket damage within minutes.
How often should I replace my Hyundai radiator cap?
Fit a new cap with every major coolant change, or every four years. At around R150, it is cheap insurance against an overheating bill that can reach R30,000 on a Hyundai 1.6 CRDi or T-GDi engine with head damage.
Why is coolant leaking from my Hyundai radiator cap?
The rubber seal inside the cap has hardened and lost grip, or the spring has weakened. A cracked expansion tank neck does the same. Always replace the cap first, because it is the cheapest part to rule out.
