Subaru WRX (2022+) Radiator & Cooling FAQ's

Please read our FAQs page to find out more.

What cooling upgrades help the FA24 during summer or track use?

An aluminum radiator, improved shrouds/fans, and silicone hoses increase heat rejection. Ducting the nose ensures the core sees cool ambient air.

Is an oil cooler recommended for the VB WRX?

For repeated high‑load use, yes—stabilizing oil temperature and pressure preserves film strength and keeps power consistent.

Any bleed tips after cooling‑system work?

Follow the proper procedure, elevate the nose, and verify fan operation. Air pockets cause fluctuating temps and localized hot spots.
