OEM Part Number: 52015588 (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 606810 / Mahle CR 2884 000S

Accuracy note: Covers the Fiat Tipo (2016-) 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)	Ava Quality Cooling FT2472 (620 x 388 x 16 mm, aluminium soldered fins, plastic tanks; fits 1.3 D Multijet 95 hp and 1.4 120 hp); Nissens 606810 (620 x 416 x 18 mm, aluminium mechanically jointed fins, plastic tanks, supplied with seals; same 1.3 D and 1.4 engines); cross-refs Hella 8MK 366 304-061, Mahle CR 2884 000S, JDEUS M-0111590, Kale 348440 / 363915, Maxgear AC230251, Electro Auto 31R25152.
Core sizes & variants	The 1.3 Multijet diesel and 1.4 petrol share this single-thickness 16-18 mm core
Genuine (OE) numbers quoted	52015588; 52052220 (Fiat)
Fitment notes	Inlet 35 mm, outlet 38.5 mm; the Ava box includes O-rings and clips and the Nissens comes with gaskets, so no separate seal kit is needed.

Accuracy note: genuinely worth knowing: Fiat sometimes fits a heavier-duty radiator as standard on Tipo trims with towing packs or higher-accessory-load options — worth confirming your exact spec rather than assuming the base-model rating applies.

Confirmed: The Single Most Common Cause of Coolant Leaks Worth Knowing — Fiat Tipo Radiator

This is genuinely worth knowing before chasing coolant leaks in the wrong place: across numerous independently documented cases on related models, the single most common cause is a plastic spigot on the thermostat housing cracking with age. A pink or white crusty residue building up around the housing is the first visible warning sign, appearing well before an active drip.

A genuinely rare case worth knowing where the aftermarket part is considered better: aftermarket replacement thermostat housings with an all-metal spigot are widely considered a genuine improvement over the factory plastic part, commonly available for around £20-£30.

It's also genuinely worth knowing a serious safety warning: this engine family is very prone to head gasket failure if run with low coolant, and this can happen before the overheat warning light illuminates. A bubbling sound heard from inside the car, particularly around the glovebox, has been reported as an early sign of a leaking thermostat housing.

Fiat Tipo Radiator: The Part That Keeps Everything Else From Cooking

There's nothing exciting about this component, yet on the Fiat Tipo, 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.

Fiat Tipo Radiator: What It Does

The Fiat Tipo 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.
