Parts for your 2022 Ford Fiesta-Coolant

2022 Ford Fiesta coolant — what it is and how to look after it

Per the Ford Owner’s Manual for the 2022 Fiesta and Ford workshop service information, this model is fitted with a pressurised liquid cooling system and requires an approved engine coolant (antifreeze). Ford specifies an ethylene‑glycol, long‑life OAT/P‑OAT coolant meeting the relevant Ford WSS‑M97B specification for the market and engine variant.

Coolant is a quiet workhorse in a 2022 Fiesta. It circulates through the engine and radiator to carry heat away, keeps temperatures steady on scorching summer runs and frosty alpine mornings, and protects internal passages from corrosion and scale. It also raises the boiling point and lowers the freezing point of the fluid, helps the water pump lubricate its seals, and feeds heat to the cabin heater core. On turbocharged variants, correct coolant chemistry also safeguards the turbo’s hot bearings during heat‑soak after shutdown.

For servicing, the smart move is to stick with Ford‑approved long‑life coolant that meets the specified Ford WSS‑M97B standard for the vehicle’s build and market. Don’t mix different coolant chemistries or colours
