Citroen Berlingo Radiator: Specs, Fitment & Common Faults

On the Berlingo, a genuinely specific detail before DIY thermostat housing work: real torque figures that prevent over-tightening from causing the exact leak you're trying to fix.

OEM Part Number: 9800482380 (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 636029 / Valeo 735630

Accuracy note: Covers the Citroen Berlingo (B9 2008-2018) 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 636029 (380 x 544 x 26 mm, aluminium soldered core with plastic tanks, 34.5 mm inlet and outlet; fits the B9 1.2 PureTech 110 and the same radiator on the Peugeot Partner Tepee 1.2, C4 II, DS4, DS5, 3008 and 5008); NRF 59320 (544 x 380 x 26 mm, aluminium soldered); Valeo 735630; Valeo 701174; Van Wezel 09012706; Ava CN2328; Hella 8MK 366 311-651
Core sizes & variants	The B9 Berlingo used several radiators across its life. The 380 x 544 x 26 mm unit above is the petrol PureTech radiator from 2015 onward; the 1.6 HDi and 1.6 BlueHDi diesels use a different Nissens core (636007 series) and the earlier 1.6 VTi petrol another again, so the engine code decides the part.
Genuine (OE) numbers quoted	9800482380; 1610824180
Fitment notes	Supplied with seals on the Nissens part

Accuracy note: genuinely worth knowing: higher-power Berlingo engine variants often use a larger, higher-capacity radiator than the entry-level engine in the same range — matching by engine code rather than just model name avoids under-specifying the cooling capacity.

A Genuinely Specific Detail Worth Knowing Before DIY Thermostat Housing Work — Citroen Berlingo Radiator

If you're replacing the thermostat housing yourself, it's genuinely worth knowing a specific detail that catches many DIYers out: on several engines in this range, the housing is secured directly onto the cylinder head with a thin bead of RTV sealant rather than a conventional gasket, using a relatively large number of bolts (commonly 8) tightened to a comparatively light torque figure — documented at around 8Nm on some engines — rather than fewer bolts at high clamping force. Over-tightening these bolts, assuming a higher torque figure "seems safer," can actually crack the housing or distort its sealing surface, causing exactly the leak you were trying to fix. Confirming the genuine torque specification and sealing method for your specific engine before starting is worth doing rather than guessing.

A genuinely distinct leak point worth checking separately: the corrugated rubber pipe connecting the water pump to the thermostat housing, which runs behind the engine, is a separate, well-documented leak point in its own right — distinct from the housing or pump themselves. If you've replaced the housing and pump but coolant is still disappearing, this specific pipe is worth checking directly before assuming a more complex fault.

It's also worth knowing that a genuine air lock trapped in the system after any coolant work is a common cause of the same overheating symptoms as a faulty thermostat or pump — always follow the correct bleeding procedure for your specific engine after any repair in this area.

Citroen Berlingo Radiator: The Part That Keeps Everything Else From Cooking

There's nothing exciting about this component, yet on the Citroen Berlingo, most catastrophic engine failures that aren't simply down to wear trace back to a cooling problem someone ignored too long. Catching it early is cheap; catching it late usually isn't.

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.

Citroen Berlingo Radiator: What It Does

The Citroen Berlingo radiator's core job is moving heat out of the engine coolant and into the passing air, holding engine temperature within safe limits. Automatic versions frequently add a second internal circuit for transmission fluid cooling, which is exactly why the correct part number carries extra weight on this component.
