The most common cause of milky power steering fluid is water contamination. This can occur if there is a leak in the power steering system that allows water to get in, or if the power steering fluid is not properly sealed and water vapor condenses inside the reservoir.
Coolant contamination:
Another possible cause of milky power steering fluid is coolant contamination. This can occur if the power steering system is connected to the cooling system and there is a leak that allows coolant to get into the power steering fluid.
Deteriorating seals or hoses:
If the seals or hoses in the power steering system are starting to deteriorate, they can allow air or water to get into the fluid, which can cause it to turn milky.
Overheating:
If the power steering system is overheating, it can cause the fluid to break down and turn milky.
Chemical reaction:
If the power steering fluid is not compatible with the type of metal used in the system, it can cause a chemical reaction that can lead to the fluid turning milky.
If your power steering fluid is milky, it is important to have it checked by a qualified mechanic to determine the cause and to have the problem fixed. Driving with milky power steering fluid can damage the power steering system and other parts of your car.
