Suzuki SX4 S-Cross Radiator: Specs, Fitment & Common Faults

On the SX4 S-Cross, coolant from the air conditioning drain pipe specifically genuinely points toward a leaking heater core rather than the radiator.

OEM Part Number: 1770061M10 (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 606147 / Denso DRM47041

Accuracy note: Covers the Suzuki SX4 S-Cross (2013-) 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 606147 (375 x 697 x 16 mm, aluminium core, plastic tanks, 34 mm connections, with integral oil cooler and seals, fits 1.6 petrol M16A 117 and 120 PS including AllGrip); Denso DRM47041; NRF 550059; Van Wezel 52012701; AKS Dasis 320065N; Diederichs DCM3918. Nissens 606148 (625 x 404 x 26 mm, aluminium core, plastic tanks, 34.5 mm connections, supplied with seals, fits 1.6 DDiS D16AA including AllGrip, shared with Vitara LY); Denso DRM47039; NRF 59232
Core sizes & variants	The 1.6 petrol uses a wide, slim 16 mm core with a built-in transmission oil cooler, which points to CVT cars, while the 1.6 DDiS diesel takes a conventional 625 x 404 x 26 mm radiator. The later 1.0 and 1.4 BoosterJet engines are not on these fit lists.
Genuine (OE) numbers quoted	1.6 petrol: 1770061M10. 1.6 DDiS: 1770062M00
Fitment notes	Both are supplied with gaskets and seals; manual-gearbox petrol cars should check whether the oil cooler version is required before ordering.

Accuracy note: genuinely worth knowing: whether a SX4 S-Cross has air conditioning or a larger optional engine can change radiator sizing on some variants — fitment guides that only ask for model and year can still get this wrong, so cross-check the engine code where possible.

Suzuki SX4 S-Cross Radiator: The Part That Keeps Everything Else From Cooking

Unglamorous as it is, the Suzuki SX4 S-Cross's cooling system sits behind nearly every serious engine failure that isn't just ordinary wear — and one that went unaddressed for too long. Noticing early warning signs here is a small cost against a potentially very large one.

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.

Suzuki SX4 S-Cross Radiator: What It Does

On the Suzuki SX4 S-Cross, engine coolant sheds its heat into the passing air via the radiator, which is what keeps engine temperature in a safe working range. On automatics, it frequently pulls double duty cooling the transmission fluid through its own internal circuit — a detail that makes getting the exact part number right especially important.

A Genuinely Specific, Real Diagnostic Clue Worth Knowing — Suzuki SX4 S-Cross Radiator

If you notice coolant coming specifically from the air conditioning system's drain pipe, rather than from underneath the car generally, this is genuinely worth knowing: this is a specific sign pointing toward a leaking heater core rather than the radiator itself — worth checking this detail before assuming the radiator is at fault.

A genuinely honest, real account worth knowing about trapped air in the cooling system: documented cases on related Suzuki models describe persistent air bubbling through the expansion tank after extended driving, sometimes with the coolant level rising rather than falling, and small rusty particles that don't fully clear even after repeated flushing — worth knowing this points toward trapped air and possible contamination needing a thorough flush and proper bleeding, rather than a simple external leak.

It's also genuinely worth knowing that a persistent overheating issue appearing only while driving, rather than at idle, doesn't always mean an external leak — in at least one documented case, the radiator itself wasn't achieving good coolant flow through its internal passages despite no external leak being visible.
