Thanks fellas for the reply.
Yes syringe out the old fluid and refill. Push clutch in 25 or so times and replace again.
Repeat the above 3 or 4 times if you want. Refill and drive as normal and replace again in a week or two. Dont worry , the fluid will return to a dark colour each time.
You can also look on the RHS of gearbox bellhousing to reveal a small grease nipple thingo, this is the proper fluid bleeder nipple, so you could put new fluid in the cylinder then push clutch down a few times, hold down and unscrew the nipple till most fluid is out, refill and repeat, just like doing the brakes.......but I think its possible to run into problems this way as the slave cylinder and bleeder run into the inside of bellhousing, so I avoided doing it this way, but it is up to you.
