Parts for your 2018 Ford Fiesta-Radiator

2018 Ford Fiesta Radiator: what it does and how to look after it

Based on technical sources including the Ford Owner’s Manual (2018 Fiesta, Cooling System), the Ford Workshop Manual (Section 303-03 Engine Cooling), and Ford/Motorcraft service parts catalogues, the 2018 Ford Fiesta is fitted with a conventional liquid engine cooling system featuring an aluminium crossflow radiator and an electric cooling fan. So yes, a radiator is absolutely relevant and used on this model.

The radiator’s job is straightforward but critical: it sheds the engine’s heat into the air so the Fiesta can run at the right temperature, deliver good fuel economy, and avoid damage. Coolant flows from the engine to the radiator, is cooled by air passing through the fins (with help from the fan at low speeds), then loops back to keep everything under the bonnet happy.

As part of regular servicing, it’s smart to keep the radiator and cooling system on the checklist:

• Inspect the radiator core for bent fins, debris, or coolant stains
