Haldex Fluid/Filter

Vehicles with Haldex all-wheel-drive systems (manufactured by Haldex but installed in various vehicles under different names) use specific fluid and filters designed for those AWD systems. On many vehicles with Haldex AWD, the fluid and filter are supposed to be changed periodically (as often as every two years), though some recent models come with a “lifetime” filter that doesn’t need periodic changing. Haldex systems are primarily used on front-drive-based vehicles with transverse engines. The Haldex coupling (or clutch), located at the rear differential, enables power to be automatically distributed among the wheels as needed to maintain traction.
