What happens to engine oil, power steering fluid, and brake fluid when in contact with heated exhaust components?

When engine oil, power steering fluid, and brake fluid come into contact with heated exhaust components, they can ignite. This is primarily because these fluids have relatively low flash points, making them highly flammable. Heated exhaust components can reach temperatures sufficient to ignite these fluids, especially if they are leaking or have been spilled in areas where they can come into contact with exhaust heat.

This ignition risk underscores the importance of ensuring that any leaks in these systems are promptly addressed and that flammable materials are managed carefully, particularly in areas near the exhaust system. In the context of vehicle maintenance and safety, understanding the behavior of these fluids at high temperatures is crucial for preventing fires.
