Parts for your 2022 Subaru Impreza-Coolant

2022 Subaru Impreza coolant – what it does and how to look after it

Coolant is absolutely relevant to the 2022 Subaru Impreza. The model’s 2.0‑litre FB-series petrol engine is liquid‑cooled and relies on engine coolant to manage heat. Technical sources including the 2022 Subaru Impreza Owner’s Manual (Cooling System and Specifications sections) and Subaru service information note the use of Subaru Super Coolant (the blue, long‑life P‑OAT formula) for this vehicle.

In this Impreza, coolant does a lot more than keep things from freezing. It carries heat away from the aluminium engine, prevents overheating on hot Aussie and Kiwi days, resists boiling under load, protects against internal corrosion, and lubricates the water pump. It also feeds the heater core, so a healthy cooling system means reliable cabin heat and clear demisters in winter. Subaru’s blue Super Coolant is a long‑life, pre‑mixed formulation designed to be compatible with the Impreza’s alloys, gaskets and seals, which is why the brand specifies it in the handbook and service literature.

For servicing, owners should stick with the Subaru‑specified coolant and interval. With the blue long‑life fill, Subaru typically calls for a very extended first replacement period (around 10–11 years or 200,000–220,000 km), followed by changes roughly every 5–6 years or 100,000–110,000 km. The exact numbers vary by market and model year, so it’s best to confirm in the glovebox manual or dealer schedule. Topping up should be done only with the same Subaru Super Coolant
