Second Hand Hyundai Ioniq Water Pump

It depends on the variant: the Ioniq Hybrid (1.6 GDi petrol-hybrid) and Ioniq Plug-in Hybrid (also 1.6 GDi) do have a conventional engine-driven water pump as part of the internal combustion engine cooling circuit, so used water pumps do exist for those versions. The Ioniq Electric (fully battery-electric, no combustion engine) does not have a traditional water pump in the same sense — it uses an electric coolant pump for battery and motor thermal management, which is an entirely different component. If you drive an Ioniq Electric and are searching for a water pump, you likely need an electric coolant circulation pump rather than a conventional mechanical water pump, so check with the breaker about the correct part for your drivetrain before ordering.

The first-generation Ioniq ran from 2016 to 2022 in the UK, with a facelift arriving around 2019, so a 2017 car is pre-facelift and a 2019 car sits right at that boundary. Both use the 1.6 GDi engine (code G4LE), which is the primary fitment factor for the water pump, so they may well share the same unit — but ancillary or mounting changes introduced at or around the 2019 facelift are something you should confirm with the breaker against your exact registration before purchasing.

No, trim level makes no difference whatsoever to water pump fitment on the Ioniq — SE, SE Connect, Premium, and Premium SE all share the same engine and cooling system if they are the same fuel type. The water pump follows the engine code (G4LE for the Hybrid and Plug-in Hybrid), not the badge on the boot lid. Just confirm the engine code and fuel type with the breaker and you can ignore trim entirely.

Both the Ioniq Hybrid and Ioniq Plug-in Hybrid share the 1.6 GDi petrol engine (code G4LE), so the combustion-side water pump may well be the same component. However, because the cooling systems interact differently with the additional high-voltage battery hardware on the PHEV, it is worth confirming with the breaker that the specific part number matches your car's registration before buying.

The G4LE engine code remained consistent across the Ioniq Hybrid's first-generation production run from 2016 to 2022, which is a good sign for interchangeability. That said, whether any mid-production or post-facelift changes affected the water pump or its mounting is something you should verify with the breaker against your registration, as these detail changes are not always reflected in the headline engine code.

The most useful things to supply are your engine code (found on your V5C logbook or via a VIN check — G4LE for the Hybrid and Plug-in Hybrid), your fuel type (Hybrid or Plug-in Hybrid, not Electric), and your year of registration. Body style and trim level are irrelevant to this part, so you do not need to mention them. If you drive an Ioniq Electric, let the breaker know — you will need an electric coolant pump, not a conventional mechanical water pump.
