Hi all,

The clutch fluid in my civic is gone a nice green / black colour and is overdue being replaced. From what I have read this should be a fairly simple job:

-Take most of the old fluid out of the reservoir.
-Top up with new DOT 4 fluid and keep it topped up throughout.
-Clutch down
-Open bleeder
-Close bleeder
-Pull up peddle (no pressure to spring back itself)
-2 pumps of clutch and then hold down again
-Open bleeder.....

And repeat until new fluid is coming out the bleeder. Anything ive missed, handy tips or do's and dont's? I will use a 2nd person to do the clutch work while I open and close the bleeder.

One other thing im worried about is the cap off the bleeder on the slave cylinder is missed and the thread has a bit of rust on it. I will use some penetrating fluid before trying to open it but has anyone had any problems with them shearing off?

Thanks :)

lol wtaf? :D The main problem with these fluids is that they absorb moisture, and therefore become less effective and boil quicker (causing gas in the fluid) overtime.

You should try the "if your steering stops working halfway through a turn, probably best to top up or replace your power steering fluid". (if you have it)

I wouldn't say there is a problem with the clutch but the fluid should be renewed every 2 years according to the service intervals and its been 2 and a half years now. Im doing an oil and filter change probably this weekend so thought if it needs doing and its an easy job...

If it aint broke don't fix it. They can often be a pain to bleed and thats before you consider snapping the bleed screw off.

That theory makes no sense in this context.

Also just because you'er crap at it, doesn't mean people should avoid this bit of maintenance..

It does because changing the clutch fluid out is going to make absolutely no difference.

It isn't even maintenance really, it's not on the maintenance schedule of any car I've ever had.

There's a good chance that in your car it's not a hydraulic clutch anyway. Although it's pretty damn obvious if you look under the bonnet, if there's a big lever attached to the gearbox with a cable actuating it, then no you dont have clutch fluid
