clutch fluid leak???

when i first got in my car one morning, my clutch started to woe (stuck clutch). it would keep getting stuck halfway and i would have to kick it back up. i drove about 10miles on freeway then when driving back, i noticed i could barely shift. goodthing i was passing by the exit to mach III. when i got to mach III and wally tried to move my car, it wouldnt even go to first anymore and the clutch was stuck at the way bottom. we found out that the cluthc fluid resovoir was empty and dry. we filled it back up and pumped the clutch a few times and it fixed the problem. after 20miles of driving, i checked the fluid level and it went from max to a lil below minimum so i refilled it back up with dot 4 brake fluid. so its a leak...

woudl anyone know where exactly its leaking and if the cost to fix is expensive?

You have a Slave Cylinder leak, Id say itll cost $300 at the most. Watch out though they will most likely tell you your clutch has gone bad, but in all reality your slave cylnder just leaked fluid. Check and see how much one cost and let us know. The leak will most likely be coming from the slave cylinder.
Here do this

1. Go to the transmission and check slave cylinder for leaks,also check clutch master cylinder,
2. Go look by your clutch pedal to see if its leaking there,these are your places that it could be.

+1^^

sounds like a leak from slave / master cylinder. there should be evidence of leakage.
do not buy used for these parts, they undergoe a lot of use over time.

maybe some UV die would help

but generally you would replace both for state of mind.

Check the carpet area under the clutch pedal to see if it's leaking. If it feels wet then most likely it's the master.

Check the rubber boot on the slave cylinder. If it's wet, then most likely it's the slave.

What tho said. The slave cylinder is underneath the car probably next to the transmission. This will be a 2 person job to bleed the clutch system. I had a 300zx that had 2 bleeder valves but not sure if the g has 1 or 2 bleeder valves.

You probably only need to replace one if it's leaking, I doubt both are leaking. I did a quick search online and found that the master and slave cost about $90 each not including shipping. Plus a bottle of fluid and whatever it costs to have a friend help you bleed the system.

I had a lowered DSM at one point and to raise it, I would drive up on a (one for each front wheel) 3ft section of 2X10. That would give me enough clearance to get my jack under the front without having to take the bumper off. In the end I found I had enough clearance to make a wooden ramp out of a 3' 6" piece and a 3' piece screwed together. I cut 45 degrees off the ends to make it more "ramplike" It looked like this:

I do most of my under car work with these. Enough clearance and safer than those crappy metal ramps. If I need more clearance then I break out the jack and jackstands.

No problem. I actually just double checked on prices and realized I was looking at prices for 2008 parts. I'm not sure what you've got, but for my 06 sedan it's $90 for the master and $50 for the slave. Not including shipping. Here is the website:

https://www.infinitipartsonline.com/...dan-parts.html

Just make sure you change the year, make and model to your setup. In terms of cost, it's cheap, but that doesn't include your time. You don't pay actual cash but think how much you get paid per hour and how many hours you spend on the job. At dealer rates of $80/hr (low end) the $300 price tag sounds about right. If this is your first time bleeding a clutch it'll probably take you twice as long. I like to think of it more like gaining experience.

Another note, I've had mixed luck bleeding clutches with just the front end raised (car not level) For that reason, I actually have 4 wooden ramps that I use to keep the car level when bleeding. It' might not make a difference with the G but something to think about.

Also, for safety's sake, if you've got the car up on jackstands, take one of the tires off and slide it underneath the car near where you're going to be sliding under. That way if the jackstand fails, you don't become a CSI investigation.

I personally don't do the repair kits. I don't have the experience and a new one is cheap. In fact, I don't really work too much on my car anymore. Trying to race with your daily driver causes too much work that needs to be done and it becomes not fun anymore.

I would really try to find the leak before going out and buying anything. As for a DIY, I haven't tried searching this site for it. I will post from another site though. Note, if you have to replace the master cylinder, you're going to want to bench bleed it before installing. Here it is

Jack your car up, secure it with jack stands.

Get a piece of rubber vacuum line that will fit over the bleeder on the slave cylinder.

Drink a Snapple lemonade

Washout the glass bottle and dry.

Add about 1/2 a cup of brake fluid to the bottle.

Set on the ground near the RF wheel.

Go get your Dad, tell him to hop in the car.

Top off the clutch master cylinder reservoir.

Get a 10mm wrench and crawl under the car with your hose and bottle.

Crack the bleeder with the box end of the wrench and just snug it.

Attach the rubber hose to the end of the bleeder screw, and put the other end in the bottle that previously contained tasty Snapple but now contains not so tasty brake fluid.

Open the bleeder with the open end of the wrench about half a turn.

Scream "push the clutch pedal to the floor slowly Dad and hold it there"

Watch for bubbles in the bottle.

Snug the bleeder.

Scream "release the pedal slowly Dad"

Wait 15 seconds.

Repeat opening bleeder, 1st scream, bubbles, snug bleeder, release.

After 3 cycles, top off the master cylinder.

Repeat process until all you get is clear, clean, bubble free fluid in the bottle.

Remove hose and bottle, tighten bleeder with the box end of the wrench.

Get out from under car.

Lower car from jack stands.

Top off master cylinder.

Adjust clutch pedal to taste.

Go in the house and fetch your Dad a beer like a good son and thank him for the help.

You don't need a drink, you just had a Snapple, remember?
The FSM has a similar procedure.
