DIY: Oil Cooler (scratch built install, lottsa pics).....>.

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.

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.

I missed your post in all the updates somehow. The same thing is what happened to me and caused my wreck at the track. 2 in one week is odd 

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.

Maybe my approach created a failsafe. I snugged up Ties in the valley areas, not tight enough to cut the hose on the ridges, but snug enough that the hose could not expand over the ridge areas on the fitting. Dunno. Just seemed like a logical fail safe to me. I'll be pulling the lower cover this week to do my first change since the install (3500 miles) and will report back if there is any hose creep...

More than a few have installed this very set-up with no issues..

Modshack,

Parts Racer saw the 3 ties. They did say that those are NOT recommended. FYI, I am in contact with them regarding the hose(s) separating. They are supposed to be calling the vendor for input.

Interesting as that was an intuitive guess on my part and not in any instructions..

FWIW, I dropped the pan today and this is what I found: No hose creep at all. A small amount of sweating from the fitting into the Mocal (wiped off here), but not so much as a drop onto the cover below.. Perfectly dry on the cooler end. This at 3500 miles since the install..
