Replacing the power steering fluid with new fluid does make a significant difference, primarily manifested in enhanced steering system performance and optimized driving experience. This is particularly evident in vehicles with hydraulic power steering systems, where steering resistance is noticeably reduced and feedback becomes more linear. It is best to replace the power steering fluid every 2 years or 30,000 kilometres, using only the fluid type specified in the vehicle manual (such as ATF Dexron III or dedicated PSF fluid), and avoiding mixing with non-compliant transmission fluids. Prolonged failure to replace oxidized or deteriorated fluid may lead to stiff steering, unusual noises, or even power steering pump failure, with repair costs potentially reaching 800 to 1,500 Malaysian Ringgit. Regular maintenance not only preserves steering responsiveness but also serves as an effective measure to prevent costly repairs.
