To prevent a power steering fluid leak, it is important to regularly flush the system with fresh fluid. The frequency depends on your vehicle’s model and driving habits, but typically you should flush the system every 3 months or 6,000 miles. If you notice any indications of a leak, such as a reduced power steering response or a strong smell of transmission fluid, it is important to take your vehicle in for inspection and repair as soon as possible.

When to Flush Transmission Fluid

When to flush transmission fluid varies depending on the make of your car and the type of transmission. In general, you should flush your car’s transmission fluid every 3 to 6 months, or when you replace the fluid.

To determine when your car needs a new transmission fluid, look for the manufacturer’s recommended service interval in the owner’s manual. The service interval will also be listed on the car’s oil filler cap or under the car’s hood. If your vehicle doesn’t have a service interval indicator, check with your dealership.

If you’re not sure when your vehicle needs a new transmission fluid, or if you’ve replaced the fluid but notice an issue, it’s best to flush the system and see if that resolves the issue. Flushing can also help remove old oil and debris from the system, which can improve performance.
