Is Power Steering Fluid Flammable?

March 15, 2024 | Victor Lukasso

Most auto enthusiasts always want to know if the power steering fluid is Flammable, and this article will address that question.

The power steering fluid helps make the steering wheel easy to steer while driving without exerting much force.

It’s also important to know if a power steering fluid is Flammable for security reasons because it’s primarily available in many garages, car parks, and even mechanic shops.

Yes, the power steering fluid is Flammable, but at a lower degree.


However, Due to its high flash point, many individuals would instead use the term “combustible” instead of “flammable” We shall examine its flammability to gain a better understanding of it and put an end to the controversy over whether power steering fluid is explosive or flammable.

How Flammable is the Power Steering Fluid?

Most people believe that a power steering fluid is more a combustible fluid than a flammable one.

A combustible fluid can get exited too quickly but won’t cause more harm compared to other flammable liquids like gasoline.

On the other hand, If a fluid’s flashpoint is lower than its boiling point, this is one aspect that affects its flammability. The flash point for power steering fluid is between 300 and 500 degrees Fahrenheit, which is lower than its boiling point of between 600 and 700 degrees Fahrenheit.

So, a power steering fluid is Flammable once the appropriate temperature is applied.

Does Power Steering Fluid Evaporate?: Yes, it will evaporate at the point of its flash, where it can ignite. Because of its high flash point, power steering fluid is less likely to start a fire than other materials. Instead, it might be a minor factor, particularly if the temperature rises to the evaporation point. Many knowledgeable mechanics will suggest that you fix a leak.

It would be best to fix a leaking steering fluid to avoid fire once it comes in contact with hot components.

Another thing to be aware of is that this fluid, in the rare instances when it can be the initial source of fire in a car, the liquid might start spraying or forming mists if it begins to evaporate. Even if they are below the flashpoint, spray mists can self-ignite. Burning the vapors releases toxic amounts of unburned hydrocarbons, sulfur and phosphorous oxides, carbon dioxide, and carbon monoxide.

How to Prevent Power Steering Fluid Fires?

While it’s advisable to check your car for leaks constantly, there are other preventive measures to prevent fire outbreaks due to mishandling of the power steering fluid.

  • Ensure to dispose of the steering fluid properly after use.
  • Keep in a cool place and avoid naked fire sources.
  • Store it away from kids and pets.
  • Tag it appropriately to avoid misuse.
  • Clean it immediately if it spills on your car or home.
  • Watch for leaks at all times.

Low fluid levels, noisy steering, and trouble turning the wheel are signs of a power steering fluid leak.

How to Put Off Power Steering Fluid Fire?

Foams, dry chemicals, water fog, or carbon dioxide can extinguish a power steering fluid fire.

Power Steering Fluid FAQs

What happens if the power steering fluid gets too hot?

If your power steering fluid becomes too hot, it might burn and lose its capacity to lubricate your system and maintain silent operation. Consider cleaning your system immediately if you think your power steering is burnt.

Can A Power Steering Fluid Leak Cause Fire?

A leaking power steering fluid will likely cause a fire if it’s not noticed and fixed on time.

Can you drive with no power steering fluid?

Yes, but driving your car for an extended period without the steering fluid can cause excess friction and heat, damaging seals, gaskets, and wear and tear on the pump.

Can you put water in the power steering fluid?

Not likely; water in tiny amounts is unlikely to cause much harm. Over time, most of the fluids in your car absorb a small amount of water. Given that moisture finds its way everywhere, they must be able to handle it. Water is not, however, an excellent medium for power steering.

In Conclusion

The power steering fluid is an essential component in a car responsible for the steering wheel’s malleability.

However, if the fluid isn’t handled with care, it could result in fire outbreaks, especially in contact with hot car parts.
