OEM Part Number: 253101P600 (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 67605 / Mahle CR 2108 000S

Accuracy note: Covers the Kia Venga (2010-2019) as listed in the UK aftermarket catalogues. Radiators are sold by engine, gearbox and air-conditioning fitment, and one model usually has two or three different cores — a thicker core for diesels and automatics, a thinner one for small petrols — with different hose positions, so a radiator for the wrong engine will not connect up. The references below are UK aftermarket listings whose fitment lists name this generation, labelled by brand with the core size in mm; genuine numbers are those quoted against the listing. Check your engine code and whether the car has air conditioning against your VIN, and replace the coolant and bleed the system after fitting.

Radiators (aftermarket)	Nissens 67605 (480 x 374 x 16 mm, aluminium soldered core with plastic tanks, 35 mm inlet and outlet, supplied with seals; fits the 1.4 CRDi 75/78/90 PS D4FC and 1.6 CRDi 115/128 PS D4FB, plus the Hyundai ix20 diesels); NRF 59315; Van Wezel 82012711; Mahle CR 2108 000S; Hella 8MK 366 307-701; Magneti Marelli 350213204500; Kamoka 7705423
Core sizes & variants	The diesels take the 480 mm core; the petrols take the 500 mm core with an integral oil cooler for the automatic gearbox fluid. Both are 16 mm deep with 35 mm pipes.
Genuine (OE) numbers quoted	253101P600; 253101P200 (diesel); 253101O050; 253101P550; 253101P050 (petrol)
Fitment notes	Both Nissens parts are supplied with seals; the petrol radiator was out of stock at the time of writing, with NRF 59287 and Van Wezel 82012709 as the stocked equivalents.

Accuracy note: genuinely worth knowing: automatic gearbox Vengas typically need a radiator with a built-in transmission oil cooler that manual versions don't have — ordering the manual-spec part for an automatic car will fit, but won't cool the gearbox oil properly.

A Genuinely Honest Account Worth Knowing If the Smell Persists — Kia Venga Radiator

This is genuinely worth knowing if you're chasing a coolant smell that won't go away: one documented case on a related model saw the radiator, thermostat, and thermostat housing all replaced in turn, with the car not overheating, yet the smell of coolant persisted after driving. If you've replaced the obvious components and the smell remains, it's genuinely worth having the heater core checked specifically.

A genuinely useful diagnostic distinction worth knowing: a leak from the water pump's weep hole tends to show ongoing, visible wetness, whereas a leak from a plastic radiator tank seal can dry up quickly once system pressure is released, making it considerably harder to spot on a static inspection.

It's also worth knowing that the thermostat housing sits toward the front of the engine, higher up than where normal AC condensation would appear.

Kia Venga Radiator: The Part That Keeps Everything Else From Cooking

Few parts get less attention than this one, but on the Kia Venga, a neglected cooling system is behind the vast majority of avoidable serious engine failures. Noticing the early warning signs costs nothing and can save a genuinely large repair bill down the line.

Before you buy: radiator size and design vary significantly by engine size, transmission type, and whether your car has air conditioning. Always confirm against your VIN before ordering.

Kia Venga Radiator: What It Does

On the Kia Venga, coolant runs through the radiator to shed engine heat into the airflow, keeping temperatures in check. On many automatics, a separate internal circuit inside the same unit also cools the transmission fluid — one more reason a mismatched part number causes more than just a cooling problem.
