Peugeot 2008 Radiator: Specs, Fitment & Common Faults

On the 2008, which side a coolant leak comes from often tells you whether it's the water pump or thermostat housing — plus why "no puddle" doesn't mean no leak.

OEM Part Number: confirm via VIN — radiators (aftermarket) Nissens 63502 / NRF 53531

Accuracy note: Covers the Peugeot 2008 (2013-2019) 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 63502 (380 x 544 x 23 mm, without cap, without expansion tank, with gaskets/seals); Nissens 61284 (380 x 415 x 23 mm, without gasket/seal); Nissens 63502A (380 x 538 x 26 mm, with sealing cap, with gaskets/seals); Nissens 636007 (380 x 544 x 23 mm, without cap, without expansion tank, with gaskets/seals); NRF 53531 (409 x 380 x 27 mm, with attachment parts); NRF 58312A (563 x 378 x 18 mm, with adapter); NRF 53424A (563 x 380 x 23 mm, with bore for sensor, with adapter); NRF 58226A (544 x 380 x 23 mm)
Core sizes & variants	544 mm core for most engines, with a shorter 415 mm core on some petrols.
Genuine (OE) numbers quoted	None quoted in catalogue listings — order a genuine unit against your VIN
Fitment notes	Check whether your radiator has the sensor bore before ordering, as some NRF items are specific to it.

Accuracy note: genuinely worth knowing: automatic gearbox 2008s 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 Genuine, Useful Diagnostic Shortcut for RHD Cars — Peugeot 2008 Radiator

If you've found a coolant leak and can see roughly which side of the engine bay it's coming from, this is genuinely useful to know on a right-hand-drive UK car: a leak from the driver's side generally points to the water pump, while a leak from the passenger side generally points to the thermostat housing — both are common, well-documented failure points, and knowing which side narrows down the likely cause considerably before a garage even looks at it.

A genuinely important point worth knowing: these leaks don't always produce a visible puddle on the ground. Several owners report a coolant reservoir that empties gradually over days with no pool ever appearing underneath the car — the leak can be fine enough that it simply mists away once the engine reaches full temperature, evaporating before it ever reaches the ground. Don't take "no puddle underneath the car" as proof there's no leak; a steadily dropping coolant level with genuinely no visible pool anywhere is still worth investigating as a likely thermostat housing or water pump seal issue.

It's also worth knowing that both the water pump and thermostat housing have been revised by Peugeot over time — if you're having either replaced, confirming you're getting the current, updated part reference rather than an older superseded version is worth asking about directly.

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.

Peugeot 2008 Radiator: What It Does

On the Peugeot 2008, 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.
