What is the flash point of power steering fluid?

• A. 350°F
• B. 320°F
• C. 400°F
• D. 450°F

Answer: (A)

Understanding the flash point helps you gauge how easily a liquid’s vapors can ignite in air when an ignition source is present. Power steering fluid, a petroleum-based hydraulic fluid, has a relatively moderate flash point, commonly around 350°F (177°C). That means at engine temperatures approaching this value, the vapors can form an ignitable mixture if a flame or spark is present. Among the options, 350°F matches the standard publication data for typical power steering fluids, making it the best answer. The other numbers are not representative of this fluid’s usual vapor-ignition threshold. (Remember, the flash point is about ignitable vapors with an ignition source, not spontaneous combustion.)
