Is Power Steering Fluid Flammable: Safeguarding Your Vehicle’s Safety

Is Power Steering Fluid Flammable?

Power steering fluid is an essential component in vehicles that have power steering systems. It helps in ensuring smooth and easy steering by providing hydraulic assistance to the driver. While it is crucial for the proper functioning of the power steering system, many car owners wonder if power steering fluid is flammable. In this blog post, we will address this question and provide you with a comprehensive answer.

Understanding Power Steering Fluid

Before we delve into its flammability, let us first understand what power steering fluid is and its purpose in a vehicle. Power steering fluid is a type of hydraulic fluid that transmits power in the power steering system. It works by transferring force from the driver’s steering input to the steering mechanism, allowing for easier steering at low speeds and sharper turns.

The Composition of Power Steering Fluid

Power steering fluid is typically composed of a base oil, additives, and sometimes a dye for identification purposes. The base oil can be mineral oil, synthetic oil, or a combination of the two. Additives are added to the fluid to improve its performance, such as reducing friction, preventing corrosion, and enhancing heat resistance.

Flammability of Power Steering Fluid

Power steering fluid is not inherently flammable. The base oils used in power steering fluid, whether mineral or synthetic, have high flash points, which make them resistant to igniting at normal operating temperatures. Flash point refers to the lowest temperature at which vapors of a substance can ignite when exposed to an open flame or spark.

However, it is essential to note that although power steering fluid itself may not be highly flammable, it can become a fire hazard under certain conditions. If power steering fluid leaks onto a hot surface, such as an engine component or exhaust manifold, it can reach temperatures that exceed its flash point and ignite. This can lead to a fire, posing a significant danger.

Preventing Fire Hazards

To prevent fire hazards related to power steering fluid, it is crucial to perform regular maintenance on your vehicle and address any leaks promptly. Here are a few preventive measures:

  • Regularly check power steering fluid levels and inspect for any signs of leakage.
  • If you notice a power steering fluid leak, have it repaired by a qualified mechanic as soon as possible.
  • Avoid parking your vehicle over tall grass or combustible materials as leaked power steering fluid can drip onto these surfaces and increase the risk of fire.
  • Be cautious when handling power steering fluid. Avoid smoking or using open flames near areas where the fluid is being handled or poured.

What to Do in Case of a Power Steering Fluid Fire

If a fire does occur due to power steering fluid, it is important to know how to respond safely. Follow these steps:

  1. Stay calm and park your vehicle in a safe location away from other vehicles and flammable materials.
  2. Turn off the engine of the vehicle and evacuate all passengers.
  3. Call the emergency services and inform them about the situation.
  4. Do not attempt to open the hood or handle the fire yourself unless you have proper training and equipment.

Frequently Asked Questions On Is Power Steering Fluid Flammable: Safeguarding Your Vehicle’s Safety

Is Power Steering Fluid Flammable?

Power steering fluid is not flammable and is specifically designed to resist ignition or combustion.

Can Power Steering Fluid Catch Fire?

No, power steering fluid has a high flash point and is not prone to catching fire under normal conditions.

What Happens If Power Steering Fluid Ignites?

If power steering fluid were to ignite, it could potentially cause damage to the surrounding components or escalate into a fire. However, this is highly unlikely.

Is There A Risk Of Explosion With Power Steering Fluid?

No, power steering fluid does not pose a risk of explosion as it does not generate flammable vapors.


In summary, power steering fluid itself is not highly flammable. However, when exposed to high temperatures caused by leaks or contact with hot surfaces, it can become a fire hazard. Regular maintenance, prompt repairs, and taking preventive measures are essential to minimize the risk of fire. If a power steering fluid fire does occur, prioritize your safety and contact emergency services immediately.
