Volkswagen Sharan Radiator: Specs, Fitment & Common Faults

If your Sharan has an EA888 TSI engine, VW has legally admitted to using "inferior thermoplastic materials" in the water pump housing — a real class-action settlement covers this.

OEM Part Number: confirm via VIN — radiators (aftermarket) Nissens 65330 / Valeo 735617

Accuracy note: Covers the Volkswagen Sharan (7N 2010-) 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 65330 (650 x 434 x 32 mm, aluminium soldered core with plastic tanks, 32.5 mm inlet and outlet, supplied with seals; fits the 1.4 TSI 150 PS CAVA/CTHA, 2.0 TDI 115/136/140/170/177 PS including 4Motion and the 2.0 TSI 200 PS, and the SEAT Alhambra II and Tiguan 5N with the same engines); NRF 59352; Valeo 735617; Mahle CR 813 000S; Hella 8MK 366 302-451; Prasco VG809R006; Ridex 470R1032
Core sizes & variants	One 32 mm deep radiator covers every petrol and diesel Sharan 7N, manual or DSG, front or four-wheel drive.
Genuine (OE) numbers quoted	None quoted in catalogue listings — order a genuine unit against your VIN
Fitment notes	Supplied with seals; the 32.5 mm hose stubs match the Tiguan 5N and Alhambra II so the same part serves all three.

Accuracy note: genuinely worth knowing: many Sharan radiators are engine-code specific rather than universal across the range — the engine code is usually stamped on the block or listed on the VIN plate, and it's the most reliable way to confirm fitment.

Confirmed: A Genuinely Serious, Class-Action-Level Design Flaw on TSI Engines — Volkswagen Sharan Radiator

If your car has a TSI turbo petrol engine (particularly the EA888 family used across much of VW's range from around 2015 onward), this is genuinely the single most important thing to know before anything else on this page. The water pump and thermostat are combined into one integrated plastic housing, and this plastic becomes brittle and develops hairline cracks after thousands of ordinary heat cycles — leading to a coolant leak that's often difficult to spot at first. This isn't a minor manufacturing quirk: VW has confirmed through legal documents that "inferior thermoplastic materials were used" in these water pump components, and the issue has been the subject of multiple class-action lawsuits.

What VW's settlement genuinely offers: a Technical Service Bulletin extends the warranty on this specific part to 8 years/80,000 miles, and the class-action settlement goes further still — up to 10 years/100,000 miles warranty, reimbursement of qualifying repairs, and crucially, reimbursement of up to £3,300 for consequential damage if the leak went undiagnosed long enough to damage the turbocharger or EGR system. If you've paid for this repair or suffered related engine damage, it's genuinely worth checking whether you qualify before assuming the cost is yours to bear.

Watch for a low coolant warning, a sweet smell in the engine bay (especially after motorway driving), or fault codes P00B7, P2681, P1889, or P0128 — any of these are worth investigating immediately rather than topping up and continuing, since this failure can escalate from a slow leak to sudden, severe overheating within minutes. If this does need replacing, the entire water pump and thermostat housing assembly must be replaced together — never just one part of it.

Volkswagen Sharan Radiator: The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but on the Volkswagen Sharan, almost every serious engine failure that isn't wear-related traces back to a cooling system problem left unaddressed. Catching the early signs here is genuinely cheap insurance against a much bigger 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.

Volkswagen Sharan Radiator: What It Does

The Volkswagen Sharan's radiator transfers heat from the engine coolant to the surrounding air, keeping engine temperature within a safe operating range. On automatic versions, it often also cools transmission fluid through a separate internal circuit — one more reason the correct part number matters so much here.
