Hyundai i20 Coolant Reservoirs
Whether your i20 is an early or late build, we match the coolant reservoirs to your derivative rather than to the badge
What Are Hyundai i20 Coolant Reservoirs?
The coolant reservoir — also called the expansion tank — is the plastic bottle that holds overflow coolant as your Hyundai's engine heats and cools. Getz, i20, Accent, Tucson, Creta and Elantra all suffer hairline cracks in the tank neck or filler cap seat, especially on high-mileage SA cars.
Signs You Need New Coolant Reservoirs
What a parts desk needs to know about your i20
i20 owners are usually surprised by how much turns on the generation code — PB, then GB, then the current BC3 all sold here.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.
- 1
Find the generation code on your i20 — it appears on the VIN plate and on the original registration paperwork.
- 2
Confirm the engine family. The i20 ran Kappa 1.2, Gamma 1.4 and Kappa 1.0 T-GDi (N Line) in this market.
- 3
Send both to us with the coolant reservoirs 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 i20shares its Kappa and Gamma engine families with the Kia Rio — which widens where we can look when local stock is thin.
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 Coolant Reservoirs
Will coolant reservoirs 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 coolant reservoirs 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.
How much does a Hyundai coolant reservoir cost?
SA retail is friendly — Getz expansion tanks are common stock and an aftermarket tank fitting Getz/i20/Accent/Elantra/Creta/Tucson runs around R707. Labour is one hour. Send your VIN for the exact part-number match.
What are the symptoms of a cracked coolant reservoir?
Slowly dropping coolant level, a sweet coolant smell after driving and white scale deposits around the tank seams. On Getz and i20 models the crack typically starts at the filler neck — look for a damp patch under pressure with the cap on.
Why does my Hyundai keep losing coolant?
A cracked expansion tank is the most common cause across Getz, i20 and Accent — well-documented on Hyundai Forums. Other suspects are a perished radiator cap, a weeping hose clamp or a head-gasket leak. Pressure-test the system to locate it.
Can I drive my Hyundai with a leaking coolant reservoir?
Only briefly and only with the level topped up. A leaking tank loses pressure, which drops the boiling point of the coolant and causes overheating. Overheating a 1.6 T-GDi or 2.0 CRDi can warp the head — far more expensive to fix than a new tank.
Where can I buy a Hyundai expansion tank in South Africa?
We source reservoirs nationally through our SA supplier network. Getz/i20/Accent tanks are common stock; Creta and Elantra units need ordering. Send us your VIN for a same-day quote.
Let us confirm the coolant reservoirs before you buy
Photos of the old part and your VIN are usually all we need. We confirm the coolant reservoirs against your i20 before quoting, not after.
