Default Need help adding clutch fluid

I have a 94 six-speed and need to add clutch fluid. I can see the clutch master cylinder, but can't get to it. I read another thread that said to remove two screws on the computer to access the cylinder. Which two screws need to be removed? A picture would be very helpful. I am not mechanically inclined in any way (I used my Haynes book to get this far) but I don't know how to get the computer out of the way to add the fluid. I would really appreciate any help anyone can give me. Thanks!

There are THREE nuts (10mm) on the ECM that must be removed so as to access the clutch master.

I don't have a pic handy, the first 2 nuts are easy to see, the final one is under the bracket, above the cruise control servo. Kneel down next to the battery and you can see it. I suggest not reinstalling that nut.

Check this pic:



See the circles and the arrow? Thems are the nuts.

Note: This pic is from a 1990, but 1990-1996 is VERY similar.

Remove the ECM from the bracket and that's that.

The cap can be very tight!!!

Default Thanks Bogus!

I found the easy two and am looking for the third. Does 10mm mean I need a metric tool?

Sounds like you need some tools and a lesson or two on how to use them. Just remember, practice and "tool time" is what you'll need to work on your Vette. Oh, throw that Haynes book away and buy a good set of Helm's Manuals for your year Vette. Take a trip to Sears and get started with a good mechanic's tool set as they have both metric and standard. If you are going to start maintaining your Vette on your own, you'll need a good collection of tools.
The clutch res is easy to get to after you lay the computer aside. The real problem is getting the top off without breaking anything. It doesn't take a lot of fluid to fill it.

The 94 does not have the black bracket next to the firewall as shown on bogus's pic. All it takes for me to add fluid in my 94 is a hand reaching in on each side to unscrew the clutch slave lid, then a skinny funnel to pour it in.

If the lid is on super-tight you might have to remove ECM to get a good grip, but hopefully you can avoid that.

There are only two screws on a 94. They are the screws farthest away from the windshield as you look down on the PCM. Then the PCM lifts out of the way.

The first time you may need channel locks to get the cap off, it won't be finger tight.

Default Thanks!

Thanks to everyone for your help! I can reach the lid -- just can't get it off, but I really appreciate the tip that there are only two screws on the 94 -- no wonder I couldn't find the third! I borrowed a metric tool set -- and will give it a shot this morning.

I'm a female who loves her vette, but I have no plans to start working on it myself. I just want to get it driveable so I can get it to the shop without the cost of a tow.

Thanks again for all your help!

Default Too Cute!

Girls like vettes too -- we just don't want to work on them! I think you'd all agree if I'm standing in the garage with a wrench going "righty tighty, lefty loosey" I have no business doing anything mechanical!

After you refill the reservoir push the clutch pedal 20 or more times to purge any air that got into the system. This will work on a 94 slave.
