Is a power steering fluid flush really necessary?

It is indeed necessary to replace the power steering fluid. Although manufacturers usually do not strictly specify a replacement interval, It is best to perform a complete replacement every 2 years or 30,000 kilometres to ensure the optimal performance of the steering system. Power steering fluid is prone to deterioration in high-temperature and high-humidity environments. During the operation, the engine should be started and the steering wheel turned repeatedly to completely drain the old fluid and ensure thorough circulation of the new fluid. Regular replacement of power steering fluid not only maintains light steering wheel operation but also extends the service life of steering system components and avoids maintenance costs caused by fluid deterioration. For example, the cost of replacing a steering pump can be as high as RM800 to RM1500. For older vehicles or those frequently driven in congested areas, the maintenance interval should be shortened further.
