Exhaust Actuator replacement

Hi,

Anything is possible, but I would suggest rechecking the timing prior to putting things together.

I read through the manual, and it indicates using a camshaft holding tool. So, based on that, I would say you will need to redo timing/adjust.

Take a look at the directions below. Read through them and let me know your thoughts.

Take care and let me know.

Hi Joe, I didn't know you replied to me, until just now. Thank you. I haven't learned much since I posted this. My problem is, the exhaust actuator sprocket on the 07 L5 has a different part number than the 09 actuator. I was told to get the 07 engine, and the 09 PCM's tuned, but I can't find anyone in my area to tune my PCMs. I'm thinking if I change the 07 actuator that's on my engine now, and put the 09 actuator on my engine, my engine would run right. Someone suggested to change the actuator without losing the timing tensioner. To get to the tensioner on the L5, is hours of work. I would like to know if anyone has tried to change the exhaust actuator sprocket before I start. I find it hard to believe it can be done without losing the tensioner. My thoughts though. Thanks for your support, well appreciated!

Hi,

They are certainly two different parts. If you look at the two pics below, the first is for the 07 and the second the 09. You can see the part numbers.

As far as replacing the actuator, you can do it without losing the timing, but you will need to remove tension. It will require a couple of special tools. If you look at the directions above, they show how it's done.

It makes sense that you need the correct one installed. If the PCM is for the 09, it is getting a different signal than it needs.

Let me know if this helps. Also, we'll see if anyone jumps in that has done it.

Take care,

Joe
