Noticed the clutch wasn't as stiff as before when I first would start the car. My neighbor pointed out the dripping and followed the source coming from the clutch master cylinder. I ordered one from Rockauto. Wanted to ask for the steps to replace the clutch master cylinder? Since it's a sealed system.

Depending on your sales code M86 or MU3 you will need to use that process. I don't see much difference so I am not sure it matters.

Here is a guide that will help as well:

Below is the process from the manual including how to bleed it. Please let us know if you have other questions. Thanks

If the clutch master cylinder is by the power brake booster then what component is at the end of the fluid hose that's connected by the transmission?

Found the part's name mistaken it. It's the Elbow Actuator Cylinder.

Sorry for the delay. They call that the clutch actuator cylinder or the slave cylinder. It appears if you search the part number that is the last screen shot below, that there are some available. Let us know if you are looking at a different part.

Thanks

The clutch actuator cylinder line, the leak is coming from the end piece that's connected to the elbow assembly clutch actuator cylinder, where the bleeder valve is close to. Hopefully just replacing the line could fix the situation but if that doesn't then the piece that the bleeder valve is also connected to is the culprit.
