    Thread: replacing oil cooler o-ring

    1. 01-04-2009 01:33 PM #26
      I don't know what the unit is above my oil filter, some electric fan/blow/compressor of some sort, but did folks who have done this taken that off, I have no access to the cooler from above, so i guess i need to go at it from the bottom?

      took an hour up on the lift. no access from the top. Biggest problem was finding a socket for the nut.

      Did mine today after letting the car sit for 2 weeks. after replacing the downpipe, it started pissing yesterday.
      Gasket - VW dealer - $5 (several in stock)
      Oil and filter $15 autozone
      1 1/16 deep socket at autozone $6
      can of brake cleaner $3 autozone
      Time - 1 hour.
      Old gasket came out in about a dozen pieces. new gasket had the little loops to hook onto the cooler.
      pipe came out with a pair of needle nose pliers.
      Tightened the nut against the old filter to tighten the pipe back into the cooler. Removed the filter and tightened the nut.
      With this thread it was a breeze! I was originally looking at the 2 allen bolts in the top to the adapter going to the block hoping I didn't have to take those corroded SOBs out.
      Thanks!

      do you have to drain the oil to remove the oil cooler

    5. 01-25-2009 06:40 PM #30
      i have oil in my car still and the filter. When I take it off am I going to need to drain the oil first or can I just do the job

      Remove the filter. No need to drain the crankcase.

      I'm the one who installed my oil filter like 2 weeks ago and for whatever reason it's not coming off again. There is a bar or a plate that runs across underneath where the filter is so I cant get a filter wrench in there and I dont know what else to do. I cant fit anything, screw driver trick etc. Anyone know if thats something that can be removed easily? Or have suggestions on how to get the filter off. Its on there tight as a $@$% right now

      You can get the tube off without using vice grips! I went to a hardware store with an old oil filter and matched the threads, and bought two nuts that size. I think it was 3/4 size nut with 16 grade threads.
      1. screw nut A. on to threaded tube
      2. screw nut B. on to threaded tube up against nut A., they will lock together and create a bolt
      3. using a wrench unscrew nut A., nut B. will hold it onto the tube so you should be able to turn the tube right out of the housing.
      4. replace O-ring and put back together the same way you took it off, only this time turn nut B. while nut A. holds it in place and you should be able to turn the tube back in.
      If you can't find the right size nuts at the hardware store you could use the one nut that holds the oil cooler and an oil filter.

      Jamb nut. Good suggestion.

      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.

      Both of my ABAs need it. The Jetta with 253K (again!) and the Cabrio with 77K.

      if you un thread the pipe nipple that the oil finter actually screws onto, then you dont have to pull it down very far at all, just slip in a new o ring.

      and just so you know, oil filter o rings work fantastic in place of the vw o ring.

      Here's to my driveway covered in oil this AM. At least I let the car idle and got to see the carnage rather than just drive away.

      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.

      you guys are not very creative..

      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

      You must be on the crack if you're paying $50 for the oring. It's like $4 on GAP

      maybe he got got the prices mixed up on the crack and the o-ring..

      see, the gram of CRACK should be 50$, not the o-ring!

      lmao..

      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
