Exhaust valve repair attempt

[Zitrosounds]

In case anyone wondered what the guts of the actuators look like. I was going to see if I could manufacture a replacement cog for the actuator. Although it is feasible, it is not cost effective. So I canned that idea. I did learn a few things. The composite material used holds up incredibly well to heat. The company that supplies the actuator is called Küster and they are german. The actuator itself is used on many different cars. I only saw one variation where the Cog did not use the spring setup. Either way, the Actuator motor itself did not fail but the Cog itself did. The portion that is exposed and attaches to the spring is where it broke. I believe there was debris blocking the valve from either opening or closing all the way and it eventually wore down the attachment point. I first attempted to open the housing by applying heat and softening the adhesive. That proved to be more difficult than I expected. So then I just cut around the sesm. That actually was the easiest method. I was trying to preserve the case as much as possible in case I was too reuse it and replacing the Cog. The new actuator has been ordered through white bear Ford and was about $100 including shipping. the MSRP on the piece is about $150. Ford part number FR3Z-5K245-A, valve actuator.

Kudos for trying to fix it. I really enjoy the active exhaust on my GT however now I kind of wish I didn't get it. Just one more thing to replace and I didn't realize it would shut down drive modes selections when it fails.

From the looks of that assembly . We may now affirm that the active exhaust option is a failure point at best . I for 1 of many have found similar failure components in the designed as specified engineering with the S550 . Sand bagged assemblies that are prone to failure . There are 4 little motors that open and supposedly adjust the blend doors for heating and cooling the interior ..

Isn't the GT variable exhaust different? I believe its built into the muffler and actuator not removable. Which would require the muffler itself replaced if the actuator fails.

No offense, but I would never get active exhaust. In the history of cars, no active exhaust has ever been long-term reliable. Unless it's attached to a Honda or Toyota, even if it's a Ford part, of course. Haha.

I am not sure about the historical reliability of active exhaust systems. BUT!!!! the fact that it disables other functions is a fail. The after market has come through for those that want to by pass the valve and have it open or closed. I personally like the active exhaust feature especially on the R especially with the Borla Atak. But to each their own.

Ford in general is pretty reliable. Especially long term. I've owned and daily driven many Fords, and they rarely let me down. Don't get me started on the Honda Accord I once owned. I will never buy another one of those POS cars.

To be clear, this part was not designed or manufactured by Ford.

That part should be made from metal...
