350z PS tank on my S13, no more leaks!

[charles]

As I'm sure many of you autox'ers experience losing 1/4th of your power steering fluid out of the cap on the stock S13 PS tank over the course of a day, I thought I would post up my fix.

I looked at aftermarket tanks, all $80+ for anything decent.....

Decided one night to inspect closer on my Z roadster..... one large nipple about the size you need for factory S13 hose and one small.........check. Good sealing cap design........check.

The 5/8" hose was a very tight fit even with some WD but I got it on there.

Bought a used one on ebay for about $30 shipped including the bracket.

The Z PS tank design is MUCH better and looks nearly impossible to leak. I took a spirited test drive around the block and got 0 fluid leak where I would have flung PS fluid all over with the stock tank. 2 events this weekend to confirm.

Pretty sure the G35 tanks are the same, it's also lighter than the stock metal tank.

Here are a few pics: I don't have a bench vise to bend the Z bracket the way I need so it's not 100% level right now.

cool. i keep noticing wet spot right under the tank but im like wtf how is this thing leaking. Only after a auto x run though have i seen the wet spot.

I fixed mine too. I just took the damn thing out.

Good work on yours though. For auto X, you gotta keep the power steering. not so much the issue for me.

Definitely doing this soon.

+1.

Did a 3-day event this past weekend and ended up ziptying a tshirt around the top of the ps reservoir to hold the fluid in.

Great job. I'll definitely be doing this soon.

Update: Saturday was what our local corvette club calls "autocross" which is mostly 75-90mph course(10 cones maybe)...... today was a normal autoX type course.... probably 20-25 runs total... no leaks...

PS is for losers.

I just run my PS level lower (at the bottom of the dipstick when hot) on my DE reservoir and don't have issues with leaks on a stock system with no cooler.

It still mystifies me that anyone is having a problem with the P/S fluid sloshing out. I have never leaked even a single drop of P/S fluid EVER, no matter what the level was set at. Even at the streets of willow in 100* + weather, nothing.

[Bumnah]

I kinda think my system isn't bled properly.

How are you guys bleeding your system?

I just pour ATF fluid in the reservoir, and move the wheel left to right, until It stops taking in fluid.

[BeerBringer]

Are you suppose to bleed the system? =P
I use the same solution as e1_griego to solve the problem. A ziptied rag around the reservoir.
First I thougth I hade a boiling fluid problem. But as the level has droped the problem has stoped.

I think it's more a matter of non-sealing caps rather than boiling fluid. It sloshes around in there pretty good while cornering, and if the cap isn't sealed well, it WILL leak out.

My leak issue was resolved when I installed a PS cooler.

My PS just quit working altogether when I installed a PS cooler. :shrug:
