My friend and I did the mod and everything was fine, but after the road test the was some bad leaking around the elbows. We pulled them off and found that the treads were stripped off the elbows. I think that we might have been shipped the wrong size elbows. While he was installing the elbows he complained the they were tight, but he thought it was to prevent leaks. Luckly the oil cooler threading doesn't look damaged.

Those are tapered NPT threads. Overtightening them could be a problem with the aluminum fitting. There are steel elbows available too that should be a little sturdier. I did use some sealing tape originally, but had to re-seal one so I used a high temp Loctite sealer on the other...Both work. Do not over tighten after snug and in alignment

Thanks for the info. I think he over torqued them. He was cranking on them pretty hard. I should be getting some moe fittings in today.

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

It looks to me like Modshack used some plumbers tape there to ensure a good seal.

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?

I spent 23 years in aerospce testing jet engines and we used aeroquip fittings but we used the braided stainless lines with the crimped fittings. I know they cost more but I would have more peice of mind knowing that the fittiings are going to hold. I am in the process of puting mine together. I have seen installations where the fittings are pointed down so that you can drain the system. I am going to put a tee at the bottom of each port. Pipe thread to 90 deg and 180 deg fitting, hoses will attach to the 90 deg fittings and a AN cap with saftey wire hole so I can saftey wire the cap to the tee so it will not come loose or loose it, I just may saftey wire all the fittings. When I drain the oil off comes the cap. I don,t want to lose a motor. The problem may be with the inside diameter of the hode you are using. I would check aeroquip guide for proper inside diameter of hose to use. They need to feel as they will not go on at all, you need to lube it up to get it on. You may get some expansion on the hose from the heat but I would think it would be minimal. Don't get me wrong but there are a few things that I would not DYI and this is one of them.

Could you post photos before and after installation!

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

teejnut · 02-27-2010, 12:44 PM

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:

Aeroquip Socketless Hose - It is real! - Team Camaro Tech

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.
