3. What causes power steering fluid to leak from the cap?

Several factors can cause power steering fluid to leak from the cap. These include a worn seal on the power steering pump, cracked or loose power steering fluid hose, or excessive pressure in the power steering system due to overfilled reservoir, which can blow seals.

4. Is it OK to drive if power steering goes out?

It is not advisable to drive if the power steering goes out completely. Most newer vehicles are designed to work properly with a power steering pump. It is recommended to drop off the vehicle at a mechanic to have it repaired.
