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

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.

To Eaton:

I am contacting you about one of your hose products that put me in a very dangerous situation recently. I purchased the AER-FBN1000-10 Aeroquip Socketless Hose and installed it on an oil cooler on my car. I followed these instructions and it was performing admirably.

http://www.the370z.com/diy-section-d...ttsa-pics.html

However while driving on Friday (2/26/10) the hose connecting to the front of the oil cooler let go and dropped all of my car's oil onto the road. As you may know, this could have been the end of my engine, but I recognized the problem and shut it down before any damage occured.

What I'd like to know:
1) How could this have happened if I installed the product correctly?
2) How to keep this from happening again (add clamps?)
3) Why should I trust clampless hoses (especially your products) now that one let go and cost me $175 (tow & parts) and a full day of labor to clean it up and put the car back together?

I will be posting our correspondence on www.the370Z.com forum so the folks who are purchasing your products (including me) can be reassured that we are working with a upstanding and reputable company.

Thank you for your help and prompt response.

Here's what Racer Parts Wholesale had to say:

"The FC5898 number refers to the color only. The FC332 is the blue
socketless hose. If you look on the hose it will also be labelled as
-10.

The hose must be cut square and the fitting pressed into the hose
until it bottoms under the collar. Do not use hose clamps."

So if you don't use clamps then you worry about the hose slipping off. If you do use clamps you worry about the inner hose getting messed up.

Describe "let go" better.

Did the hose pop off of the fitting?
Did it rip/tear?

How clean and flat were your cuts?
How much tension was on the hose where it failed?

The hose popped off the fitting, no tears. When I pulled the undertray off the car, the hose was hanging away from its I made a completely clean cut and it was flush into the small aluminum coverlette.

The tension on the hose was minimal. I had the hoses ziptied together so they would track next to each other, but there was plenty of wiggle and flex room. To be specific, each hose can be pushed 1 inch in either direction yet are still held by zip ties to keep them in place. I do have the hoses wrapped in a leftover hose on the parts that might touch other areas of the vehicle so there are no worn areas that may cause a problem.

Its only been a day, but I've yet to hear from Aeroquip or Eaton.

I talked with Aeroquip to get a better understanding of the differences between the FC598 and FC332 hoses. I was concerned because their catalog show the FC598 as a crimp connection hose. Apparently they are the same hose other than color. The crimp connector has to be used for industrial, high pressure applications and is OK for socketless connections for the oil cooler.

shumby · 03-01-2010, 12:28 PM

i believe a while ago i told you guys you should go with crimped fittings. it is not just the pressure rating you need to look at it is the temperature swings that it sees that willcause the failure. trust me I work on equipment that runs at 5000PSI and is worth millions. for the little extra cash crimped is the way to go.

Was the second post with extra pic the followup, Modshack? Interested to hear how your hoses are holding up.

I'll give one (1) rep point to the 370Z owner who actually does a video for others on the oil cooler install! Generous ain't I?

Seriously, if you have the aptitude to do your own wrenching, then you can install an oil cooler. If not—don't. Not being sarcastic or condescending...some people have it, others don't.

cab83_750 · 03-01-2010, 09:06 PM

A lot of people must be doing a lot of oil cooler install. Why? I ordered parts from Parts Racer and the 90 deg fitting is out of stock!

cab83_750 · 03-02-2010, 02:58 PM

My mistake! They are NOT (repeat NOT) recommended.

....This can cause the inner tube to be destroyed.....

Sorry. My lasik and fingers are not working right today.

Hey guys,

I found this post from Aeroquip socketless hose (FC598) - anyone else with issues? - Page 2 - LS1TECH

"The Aeroquip tech sheets indicate the FC598 should be used with crimped fittings (page 18 of the doc you linked to on post #6). Maybe the socketless fittings will still work with this hose (?), but all of the Aeroquip documentation I have found makes no mention of it; only the crimped fittings are noted for this hose.

Excuse me if I'm off base on this. I recently got a dry sump system I'll be fitting to a 4-cylinder, and it came with a length of FC598 and four socketless fittings. After reading the Aeroquip spec sheets, I'm thinking I should either get some crimped fittings or some different hose (FC332 socketless hose), and a search led me here."

Based on the post at ls1tech and here at the370z, I think I will go ahead and change my order to the blue fc332. I have nothing to lose except having a blue color.

I have also searched the web and it appears that when you slide the hose to the fitting, it is supposed to be a "major workout." Others even resort to heating the hose to help in installation. Did you guys encounter this norm, or did yours just slide over with just little force?
