He is not the first guy to do that....Finesse, not force!

has nissan included an oil cooler for the z yet?

I would not hold my breath on that. Their position on this:

Sockletless Lines Beware!
 

I installed this oil cooler to the letter (thanks ModShack!).

However I had a problem with the socketless lines - one let go while I was driving!

I noticed the front tires slipping and the anti-lock brakes kicking in. Then I smelled oil & looked in the rear view mirror to see most of my oil on the pavement. I pulled over and shut 'er down immediately.

After a tow, I jacked up the car and found one of the hoses had let go and sprayed the undertray with all of the oil. I'm cleaning it up now and will put it back together with clamps.

I'd recommend using clamps to anyone who is adding this oil cooler.

Has anyone else had problems?

Wow. There seems to be a lot of oil hose fittings blowing here lately. Not cool.

I believe this is the 2nd reported issue? Definitely makes me a little worried, has anyone who had issues try contacting Aeroquip to see what they say?

Yeah, 2 cases in the past week or two....This appears to be unusual...Maybe a bad run of hose or some other reason. The socketless fittings do not have a history of failure if you search. This is the second, from the same source. Maybe they have hose mislabeled (AN12 instead of AN10 or somesuch). At this point I would recommend clamping for additional security. Mine has been problem free for 3500 miles. I'll be pulling the pan this week for an oil change and will take a look...

Do you know what hose Racer Parts Wholesale sent you? I received FC598 and per Aeroquip's spec sheet this is not socketless and requires a crimp. FC598 requires a crimp fitting. And FC332 is the correct socketless hose. I'm going to email RPW right now and see what they say.

edit n/m... found these two threads and FC598 seems to be the correct hose:

Mine is the 598 also and according to the aeroquipt guy in the above post, that is the correct hose.

Did you lube the inside of the hose when you assembled it? (I did). Wondering if this is a variable in breaking the inner liner. Regardless, I think clamping is now the way to go on these..
I'll source smooth band clamps from http://www.mcmaster.com and update the original post with pics when I get this done..

From those threads sounds like FC598 works but FC332 is better? I might have found a local source for Fc332 going to look into that. Be interested in what kind of clamps you find.

No I didn't use lube and it seemed to go in pretty easily, wasn't that hard to push it in.

The post that Modshack refers to quotes the Aeroquip guy as saying not to use clamps or ties as they will cut the inner tube. Have this kit on order now and am not sure what to do.

go to a local hydraulic hose shop and have the hoses made to the sizes mod specified. it cost me 110 for both hoses, and wish I had done it earlier.

I don't think anything is going to burst these. btw, if you don't have a shop, I can probably get more made to order for 125 plus paypal fees. I won't be making anything off of them, just trying to help the Z community and support my local businesses.

How long are those, 48" and 62"? That's a good idea, going to check with a local shop too. I checked with them for the FC332 hose and its ~$168 for 15' worth :eek: !

Edit:
For the 2 that have failed, are they coming off of the oil filter side or oil cooler side?

only one fully failed. it was the return from the oil cooler into the filter. the other one on the filter was coming a little off. Mine are 49 and 63, I added an inch just to be safe.

The line that came off was attached to the oil cooler side.

Quite a mess, but I've cleaned it up and put clamps on all 4 ends. Ran the car and it seems to be holding fine. Oil temps up to 180 and steady in TX 65 degree weather. I decided to do this cooler b/c of the Texas summers, so the real test is in 110 degree weather with the air conditioner and running hard. I'll keep posting as we test it out.

I'm a bit worried now that I've clamped it b/c it might cut the inner tubes. I'm going to contact Aeroquip and I'll post the conversation.
