Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

kbc749 · 07-20-2015, 03:55 PM

Hello,

I would like to add my name to the list of people who have had this issue.

I was driving back from Estes Park, Colorado to Lincoln, Nebraska and Near Ogalala, my clutch failed in exactly this manner. Clutch pedal went down, did not come back up. Fortunately I was given a push start and was able to limp to a walmart where I got some DOT3 brake fluid and filled the empty clutch fluid reservoir, and was able to pump the clutch back up to have pressure.

I got the clutch pumped back up and took off, thinking all I had was a small leak, having survived the long drive to Colorado and a little spirited driving in the mountain roads. But then 5 minutes later, when i went to try and change gears, I had lost all pressure again. When I went to check the fluid, I found it was still full. Meaning I was losing pressure inside the system, and leaking as well.

I was able to limp home by pumping up the pressure every time I needed to shift out of 6th until I made it to my house, roughly 300 miles later. Thank the car gods for a large gas tank.

Took it in today, and of course it's not covered under my powertrain warranty. (I just broke 41k). So I will be trying to get it covered but I'm not expecting success.

Thanks

KBC

Thermo Tec 14010 Thermo Sleeve | eBay

This is what I got, it'll run ya roughly $20, you'll use up 70% of it, if you do both lines on the CSC..

If you buy it from this seller, he's out of NY, I don't know how the hell it took 6 days shipping from NY to DC..

DEI Titanium Exhaust Wrap works well to shield from Exhaust heat. I've used it on headers, Exhaust pipes, etc on many cars to help keep engine compartment & drive train areas protected from heat from headers/pipes. Good stuff, last long time, doesn't require pre-soak.

Yup, thats the same thing, you'd be all set.. as far as your fluid, im not sure about that, but if you're upgrading the CSC, you'd be flushing your clutch fluid, I would think you'd be using a better fluid other than the oem stuff... ie. RBF600 or the Motul 5.1 which is designed to work very well with high temps.

firulice · 07-20-2015, 10:30 PM

Would this work well? http://www.amazon.com/Thermo-Tec-135...CZ8FCDH702QG64

I'm thinking it should help keep my fluid from getting as hot?

Purchase date April 2012
Occurrence date July 2015
Mileage 58,000

About a year ago my clutch PEDAL broke, shearing off the helper spring mount. The pedal became very sloppy and difficult to shift but I replaced it with the RJM adjustable pedal and was very pleased with the results. Thanks to this website though I have since known to keep a close eye out for any CSC issues.

The car is my daily driver and I generally baby the car around town, although I have been to a few HPDEs with it. I currently run PFC 665 for the clutch line.Two weeks ago while changing my engine oil, I noticed that the Clutch reservoir fluid level was getting very low

. Prior to this, I had not had any problems with the clutch line and had it flushed at least once before. No puddles or leaks were noticed under the car or on the bottom of the transmission. I ordered the ZSpeed CSC and parked my car for a week (make sure you have a spare car if you own a nissan or anything British).

I am lucky enough to have a good friend that owns a shop with a lift, and today the two of us swapped out the CSC. The entire procedure took roughly 3 hours, and was made much easier by slightly dropping the front subframe to help tilt the transmission down. The clutch disc was noted to be plenty thick still - which is great since I didn't order a new one. Car is now doing great although the engagement point is slightly lower and grabbier, two things I can adjust with the RJM pedal.

Before I did the work myself I went to a Z shop locally and was quoted roughly $950 labour + parts. I ended up doing it myself with a friend for the price of the CSC and a few good beers (Dogfish Head, Aviator, and DuClaw).

As much as I love this car, I will say that I have been pretty disappointed by the build quality and random issues I've had - breaking clutch pedal, CSC failure, axle click, engine oil overheating, and clear coat bubbling off all over.

I totally agree. I am disappointed with the quality of this car. I loved my 350z. I had no major issues. The reliability of the 350 made me purchase the 370, but I have had to many major issues with this car.
