Land Rover Discovery Sport Radiator: Specs, Fitment & Common Faults

Confirmed: a genuine safety recall addressed a water pump belt issue on PHEV models that could rupture a coolant elbow, risking fire near the turbocharger — plus an honest account of a car visiting the dealer five times in a year with the same fault recurring.

OEM Part Number: GJ328005BB (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 606681 / Mahle CR 954 000P

Accuracy note: Covers the Land Rover Discovery Sport (2014-) 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 606681 (670 x 467 x 16 mm, aluminium core with plastic tanks, 2.0 Ingenium petrol and diesel); Mahle CR 954 000P; NRF 550269; Van Wezel 02012712; AKS Dasis 020080N; Kale 364330
Core sizes & variants	One 670 x 467 x 16 mm radiator covers every 2.0 Ingenium Discovery Sport, both Si4 petrol and TD4/SD4/D-series diesel, and is shared with the 2.0 Range Rover Evoque L538. The early 2014-2015 cars with the 2.2 SD4/TD4 diesel use a different radiator not covered here.
Genuine (OE) numbers quoted	GJ328005BB; LR075360
Fitment notes	Hose connections are 38 mm. Access requires the front bumper and slam panel to come off, so budget for the labour as well as the part.

Accuracy note: genuinely worth knowing: coolant capacity and radiator sizing on the Discovery Sport tend to track engine displacement and power output closely — a part correct for a smaller-engined version of the same model can undersize the cooling for a larger-engined one.

Land Rover Discovery Sport Radiator: The Part That Keeps Everything Else From Cooking

It's an unglamorous part, but on the Land Rover Discovery Sport, the cooling system is behind almost every serious non-wear engine failure that could have been prevented. Spotting trouble here early is about as cheap an insurance policy as exists against a genuinely expensive repair bill.

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.

Land Rover Discovery Sport Radiator: What It Does

On the Land Rover Discovery Sport, heat from the engine coolant is shed to the surrounding air through the radiator, keeping engine temperature in a safe range. On automatic gearboxes, it often doubles up, cooling transmission fluid through a separate internal circuit too — which is why getting the exact part number right matters more here than on a simple heat exchanger.

Confirmed: A Genuine Safety Recall Worth Checking Your Car Against — Land Rover Discovery Sport Radiator

This is genuinely worth checking directly on plug-in hybrid variants: a confirmed safety recall addressed a water pump drive belt issue that could cause the engine to overheat, rupturing a plastic coolant elbow. This could allow coolant to leak directly onto the hot turbocharger, creating a genuine fire risk. Dealers replace the affected coolant elbow and a related pipe free of charge — worth checking your specific VIN against the official recall register if you have a PHEV model.

A genuinely honest, real account worth knowing about how persistent this can be: one documented case saw a car visit the dealer five separate times within a single year for a coolant warning light and low coolant level, with hoses replaced and sensors changed each time, yet the exact same problem kept recurring roughly every 1,000 miles, accompanied by a faint burning smell noticed after driving. It's genuinely worth knowing this level of persistence has been documented, worth pushing for a more thorough investigation, such as a proper pressure test of the whole system, rather than accepting repeated individual component swaps that don't resolve the underlying issue.

It's also genuinely worth knowing that a damaged plastic cooling fan blade, even one with just a small crack or chip, can cause a heavy vibration capable of ruining an otherwise good water pump in under 100 miles of driving — worth inspecting the fan blades closely for any damage before assuming a water pump failure is unrelated to a separate fan issue.
