Thanks for all the helpful advice, searched the net for hours on this subject, with your information was able to take off the parts in about half hour. You probably saved me 5. Really appreciated the socket size advice and vise grips as well.
Awesome suggestion! I wish I would have read this before I started my seal replacement project. I learned the hard way to get it done, but hey, at least I learned some valuable information! Here are some pics from my job. http://f331.mail.yahoo.com/ya/...ine=1 http://f331.mail.yahoo.com/ya/...ine=1

Thanks to all above for the information.
I was able to replace the oil cooler o ring on a 1999 Jetta 2.0 AEG engine and the hoses were long enough to get the oil cooler/oil fiter flange down without removing the hoses.
The jam nuts did not work out but were not necessary. I started trying to use them and tried to just pull the hoses enough and it did not take much.
The o ring was brittle. You could snap it. The 27 mm deep socket was handy and it took some effor the losen the nut but all in all a very easy job.
I recommned this be done as preventive maintenance at least every 100K miles.
I will have to do my 97 Golf soon.
Just did mine last weekend...the oring was still ok but getting hard...I unscrewed the threaded pipe with vise grips just as stated, put the new oring on, put the threaded tube back on, secured the large nut, new oil filter, test drove it for 150 miles and all is good. I would try pulling the oil cooler down off the tube as you are just asking for more issues in my opinion. Total time with oil change included was about 1 hr.
use an old oil filter o-ring!
every time you change your oil, you throw out a perfectly good o-ring..
the o-ring from a k&n oil filter works the best in my experiences..
not a snow balls chance in hell that im paying 50 bucks for a rubber o-ring
i just replaced my oil cooler seal on my 95 2.0l gti, took me honestly 15-20 mins. ha easiest thing that i ever did on my car.
1. went to the closest dealer and bought the o-ring for $4.35
2. take oil filter off
3. take vice grips and tighten on the threads (dont f*** up the threads lol) that you would put oil filter on
4. the oil cooler will start to hang
5. replace o-ring
6. put it back together!!
dont even worry about hoses getting in the way.

yup, my 1997 jetta 2.0L (just broke 200.000 miles) just started leaking oil from the cooler, winter just hit... go figure. sure enough its the seal. seemed like an easy fix but thaught i should check here first. i think there are a couple different set ups for the coolant lines on these, but easy fix none the less. thank you all very much for the pics and proceedures, makes life much easier. keep the vdubs goin 4ever!!! lol
I'm pretty sure it was posted in the past, not my DIY, but is what I used to get mine replaced:
