Does power steering fluid need to be drained?
“Power-steering systems are sealed, meaning they should not lose fluid over time,” Peck says. “If the system needs to be topped off, the vehicle should be inspected by a technician to determine the source of the leak. Drain and refills should be part of the scheduled maintenance interval.”
Can I change power steering fluid myself?
