Why will.my clutch not engage, stays disengaged?

There is a bleeder screw on the slave cylinder. Fluid level must be properly maintained during bleeding!!

Sorry, yes clutch will not disengage. Will not shift with vehicle on.

BLEED ALL AIR FROM SYSTEM!

How far should the plunger on slave cylinder travel? Should it hit the top, mine stops about 1/2 to 1" from meeting top. Is it possible spring inside worn and need new slave cylinder?

There is no spring involved here - it is all done hydraulically! .... All air must be purged from the system which is no easy task - even for a seasoned technician .. Best route to take is seek out *hands-on* assistance from auto repair savvy personnel. Bleeding can be done by using gravity - however it is best done by two people - just like bleeding the brakes.

Ok, I understand bleeding like brakes, but there is no bleeder screw, will continue the reverse method, pushing back rod to purge air to reservoir. May have to remove altogether and bench bleed.

There should be a bleeder screw on the slave cylinder! IF not - replace it with one from NAPA for about $20.00. Best to always include engine size when inquiring about vehicle repair or parts.

2.8L or 4.3L

4.3L, thought I had put it in original question sorry. Was thinking of replacing it just in case, but noticed there is a hex key set screw where a bleeder screw may fit, going to remove and see if bleeder screw kit has one that'll fit it.

NO - that IS the bleeder screw!! Use it just like any other! ... Loosen it a bit for air to escape then tighten it back..

Ah ha! Ooof, just had crazy mind blown moment. Feel so much like a novice right now. Going to do as soon as out of work. Will keep posted! Thank you Pushrod, you are a gentleman and a scholar.

Not really - I’ve just been to automobile repair business way too long! Retired now and don’t miss it nary bit!

I always wanted to get into automobile repair business, even got a degree in automotive tech, but live in an area that, if you don't know someone or if your more educated than the guys that have been there forever, there's no chance. So practice my trade at home as much as possible.

Well I managed to stay in it for 45 years - even had my own shop - it was an ok living and I’ve done alright but in retrospect i wish I’d chosen a different path - which was certainly available to me on many occasions along the way .. Live and learn - after the fact! It is pretty much a thankless job to have anymore - it didn’t used to be this way. Glad to be done with it myself.

Just keep bleeding that shave cylinder until you’re sick of it - then do it some more! Keep master cylinder full of fluid at all times - you’ll get it working!

Opposite issue now, the clutch is always disengaged. Gears go in, but no go
