I'll respond for myself only, as Rusty is much more technically proficient. When I did my clutch, I had a lot of trouble bleeding the line, to the point where I had to pay someone else to do it for me (guy from Infiniti). Yes, if you can do it correctly, it'll probably extend the life of your CSC. If you can't, you won't be able to engage gears. I don't know your skill level, so weigh that for yourself.

Should i bother changing clutch fluid & bleeding clutch line prior to getting a date at a garage which is in 1 month plus? Maybe to extend the life of my current csc (doubt that will happen) but i also dont want to make the problem worse, car still engages gears and drives as we speak. Thanks.

Sounds like you've already been having issues. So a clutch flush could definitely help reduce the risk of something happening in that time. But you'll probably be fine as well since we're just talking about a few weeks. I'm guessing that most people wouldn't bother and most of the people that would bother are DIYers in their own garage.

In this case I would recommend a simple gravity bleed on the clutch. Ranger method the fluid in the reservoir and make sure it's topped off. Then open the bleed valve and let it drain. It will be slow. Let the reservoir drain until it is near the bottom (DO NOT LET IT EMPTY OR AIR WILL ENTER THE SYSTEM) and then close the bleed valve and top off the reservoir again. A single reservoir drain may not do the entire clutch system, but it will be close. Repeat the drain process again if you want to be sure.

If the seals are also going out in the master cylinder, it is my experience that pumping the clutch pedal makes the bleeding process more difficult and not easier like it should.

How much is needed for a complete fluid replacement?

I need to replace the DOT3 the car came with as my clutch pedal went soft yesterday. Running around on some farm roads at 3000-5000 RPMs with the A/C on and the ambient temp was around 85.

It came back periodically on the drive home and the reservoir was still full when I got it parked and checked it.

I figure it's about time as I topped 79K on the ride yesterday and it's the original fluid. Up until then I haven't had any problems other than occasionally a slight softness when it got hot.

Thx

Should be less then a liter. When you do it. DON'T let the reservoir go dry.
