If the filter screen contains debris, the fluid will be restricted from adequately supplying the power steering pump and may cause the fluid to aerate and cause a whining noise.

If debris or dirt is found in the reservoir filter screen, the reservoir should be replaced (see photo).

It may be necessary to empty the power steering reservoir to properly inspect the filter screen for contamination.

PSF-III is not available through Kia Chemicals: Use a high- quality power steering fluid. Do not use ATF in place of power steering fluid.

Some models use PSF-4, which is available through PDC.

Always use the correct recommended fluids!
