Cheap Mazda CX-3 Oil Cooler

It depends on the engine variant. The CX-3's 2.0-litre petrol and 1.5-litre diesel engines in standard naturally aspirated form do not typically feature a dedicated engine oil cooler as a serviceable bolt-on component, but the 1.8-litre diesel (SH-VAIS engine code) introduced in later models does run an oil cooler integrated into the engine assembly. If you're searching for this part, confirm your exact engine code from your V5 or a VIN check before ordering, as the part may simply not exist on your variant.

The Mazda CX-3 ran as a single generation from its UK launch in 2015, with a facelift arriving in 2018 that brought updates including changes to the engine line-up, most notably the swap from the 1.5-litre diesel to the 1.8-litre diesel. Whether an oil cooler from a post-2018 facelift car crosses over to a pre-facelift 2016 car is not straightforward - even if both carry diesel engines, the engine codes differ (SH15 vs SH18) and the components are unlikely to be interchangeable. Confirm this directly with the breaker against your registration and engine code before purchasing.

Trim level makes no difference here - the oil cooler is determined entirely by the engine code, not by whether the car is badged SE, Sport Nav, GT Sport, or SE-L Nav. All of those trims were available with the same engine options, so two CX-3s with the same engine code will need the same oil cooler regardless of trim. Just confirm your engine code and the breaker can match the part correctly.

The engine code is the single most important detail you can supply - for the CX-3 the relevant diesel codes are SH15 (1.5-litre diesel, fitted pre-facelift) and SH18 (1.8-litre diesel, fitted from the 2018 facelift onward). Your engine code appears on your V5 logbook or can be retrieved via a VIN check, and it tells the breaker exactly which variant of the engine your oil cooler needs to suit. Supplying your registration alongside the engine code will help the breaker pull the right part quickly.

The 2.0-litre naturally aspirated petrol engine (engine code PE-VPS or similar SKYACTIV-G variants) in the CX-3 does not use a separate bolt-on oil cooler in the way a diesel or turbocharged unit would. If you are seeing an oil temperature or lubrication warning, the fault is more likely to lie with the oil pump, sump, or a sensor rather than a missing cooler component. It is worth speaking to a mechanic before ordering parts to make sure you are looking for the right thing.

The oil cooler on the CX-3 relates to the engine rather than the drivetrain, so whether the donor car was front-wheel drive or AWD is not the key variable - the engine code is. That said, there can be ancillary bracket and mounting differences between specifications that are difficult to confirm without checking the specific part numbers, so always confirm compatibility with the breaker against your exact registration and engine code rather than relying on drivetrain type alone.
