Adjust cluch

Hi,

The clutch on this vehicle isn't adjustable. It has a hydraulic release system. If it is slipping, the clutch needs replaced. You didn't indicate the engine size above, so I went with a 5.3L V8 which is most common. If that is wrong, let me know.

Here are the directions for replacing the clutch on the truck. The attached pictures correlate with the directions.

The only option to "adjust" this clutch is to bleed the system because it is not a mechanical clutch. However, if you are not getting complete clutch operation more than likely you have a leak in the system somewhere. If that is the case, then you will need to disassemble and replace the part and then bleed the system again.

If you are going to do this, I would just replace everything in there so you don't have to go back in to replace something else in the near future.

I attached the process for a 6.0L which is what I assume you were going for in the header. However, I think most of the configurations are the same or close enough but let me know if yo uhave questions. Thanks
