Installation Notes
Regular replacement of the power steering filter is essential for system longevity. The procedure is straightforward but requires strict attention to cleanliness.
1.Safety and Preparation: Ensure the vehicle is parked, the engine is off, and the steering system has cooled down. Clean the area around the power steering reservoir cap thoroughly to prevent dirt from entering the system.
2.Access the Filter: Unscrew the reservoir cap. Depending on the tank design, the filter element (WG9925470033) is usually located just beneath the cap or secured by a retainer.
3.Remove Old Filter: Carefully lift out the old filter element. This is the ideal time to perform a fluid change. If changing the fluid, use a suction pump to remove the old, contaminated fluid from the tank.
4.Install New Filter: Inspect the inside of the reservoir for any sediment and wipe clean with a lint-free cloth. Insert the new WG9925470033 filter element, ensuring it is seated correctly on its base.
5.Refill and Bleed: Fill the reservoir with the manufacturer-specified hydraulic steering fluid (check your manual for the correct fluid type) up to the “MAX” mark. Start the engine and turn the steering wheel slowly from lock to lock several times to bleed any air from the system.
6.Final Check: Re-check the fluid level and top up if necessary. Ensure the reservoir cap is securely fastened with its seal intact.
