Ford Mustang V6 2005-2014: Why is My Power Steering Reservoir Leaking Foam?
If your power steering reservoir is leaking foam, there are a few potential causes to this issue. Find out a few of the most common reasons in the article.
This article applies to the Ford Mustang V6 (2005-2014).
Your power steering system has a very hard job to do. When your turn the steering wheel, you might not think about how easy the wheel rotates. However, without power steering, you would literally have to move the entire weight of the front wheels, tires, and brakes with your arms. That's why when your power steering system starts you malfunction, you feel it! A common problem on the V6 Mustangs is developing red foam around the power steering reservoir in the engine bay. This occurs due to built up moisture or air in the power steering system. Check out a few of the common fixes and diagnosis techniques to this issue below.
Materials Needed
- Paper towels
- Power steering fluid
- Flashlight
Step 1 – Visually check for leaks
The primary method of finding a leak is to visually check your power steering lines for leaks. Use a flashlight to trace your power steering lines and connections for issues. A small pinhole puncture in a hose can allow air and moisture into the system, causing issues. If you detect a leak, then replace the hose or connection as necessary. It is not worth postponing this job, as it can cause the loss of power steering and creates a dangerous situation.
Pro Tip
Check the hoses at the connection points to see if anything is loose and is allowing moisture or air in.
Step 2 – Wipe off foam and inspect in a few days
Another method suggested by multiple forum members is to wipe away the foam from the the reservoir, and check for leaks again in two or three days. Sometimes, a random event allows air or moisture into the system, making it hard to distinguish between a temporary and permanent leak. Wiping off the foam and seeing if it comes back allows you to see if the problem needs more attention. If the foam does not return, then do not worry about the power steering system, as long as the fluid level does not drop.
Pro Tip
If your power steering fluid looks dirty and you confirmed there are no leaks in the system, replace it. The fluid will degrade if it is exposed to moisture and air for a long period of time.

Step 3 – Flush and purge the system
If air is trapped in your power steering system, then flushing and purging the system can help. Follow proper procedures to flush the system of fluid and make sure no air is allowed to enter the system during the process. Once you flush the system and add new fluid, you can turn your steering wheel lock-to-lock a couple of times to purge any air left in the system. This should solve any last issues that you have with foaming brake fluid!
