Haldex Fluid and Filter

Some vehicles use an all-wheel-drive system manufactured by a company called Haldex. The Haldex AWD system controls the amount of drive torque to each individual wheel and can direct up to 85 percent of the drive torque to a single wheel when the other three wheels are losing traction.

If you have this type of AWD, it requires a certain type of fluid and filters - called Haldex fluid or a Haldex filter, which helps clean the fluid. Like many other fluids in your car, Haldex fluid and filters typically need replacement on defined intervals - often every 20,000 miles, or roughly 2 years.
