Suzuki SX4 S-Cross Radiator: OEM Part Number
| Manual gearbox, all engines | Standard radiator with no transmission cooling circuit |
|---|---|
| Automatic/CVT, all engines | A dedicated transmission fluid cooler is fitted — either built into the radiator's tank or as a separate unit connected into the coolant circuit depending on exact model and generation — confirmed as a genuinely different radiator/cooling setup from the manual version, not interchangeable without the correct cooling circuit |
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.
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.
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.
