You will not be able to match up o-rings buy them at the dealer, here are photos of them Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

MrEldo97 Posted July 8, 2008 Report Share Posted July 8, 2008 I just did my son's '03 STS and you DO NOT need to remove the oil filter adapter. It's tight but eminently doable. You do have to remove the oil filter but you can work around the filter adapter. I would just add be carefull you DON'T break the connectors like I did (broke one and spliced in a new pigtail) - screw drivers and fatigue don't mix...

Ed Hall Posted July 8, 2008 Report Share Posted July 8, 2008 If you live close to Harbor Freight, buy their 300 piece O-ring kit. This is what I did on my car. The O-ring kit from HF was cheaper than buying 1 O-ring from the dealer. Once you put the the O-ring on, be sure to not over tighten it. Link to comment Share on other sites More sharing options...

Ed Hall Posted July 8, 2008 Report Share Posted July 8, 2008 This is the kit I'm talking about. I waited for their 50% sale and bought it for about 1/2 that price. http://www.harborfreight.com/cpi/ctaf/disp...temnumber=93143 Link to comment Share on other sites More sharing options...
BodybyFisher Posted July 8, 2008 Report Share Posted July 8, 2008 If you want to leave the oil filter adapter in and work around it, with oil dripping out of it, thats fine, the manual does not call for its removal. But of course, the manual is written for guys who will STAND under the car while its on a lift also. I look for the easiest way to do things and while the manual does not call for the adapter removal, you will have LOTS of room if you do remove it. Given that this is the first time you are going to do this job, the extra room to move around and see clearly, will probably prevent you from ripping out the connector as Mr Eldo did. To me, having removed the adapter a half of dozen times, its a no brainer. The o-ring is roughtly the size of a quarter maybe a little larger, keep in mind that its not just the diameter of the o-ring but also the diamter of the rubber itself that is important. Yes, the 2 o-rings from the dealer will cost $6 to $7, whereas you can get 300 assorted for $7, with luck, it might include the one you need. But if you leave the adapter on, you won't need to worry about this.

Ed Hall Posted July 8, 2008 Report Share Posted July 8, 2008 hey ED.. how good of a fit was the o rings from the set?? thanks Mike I found an o-ring from the set that was pretty much a perfect fit.

Ac delco sensors from rockauto. Any NON hardening sealer for rubber seals will hold them in place while you install them. As you can see those seals can leak, your car is now 8 years old, while they are not leaking it wouldn't hurt to replace them and as you can see from that thread its not hard.

KHE Posted July 11, 2008 Report Share Posted July 11, 2008 I would use clean engine oil to lube the o-rings. If you need something tacky, petroleum jelly (Vaseline) could be used or grease.

Good suggestion Kevin, the problem is keeping the o-rings in place while you put the adaptor in place (and that can been awkward), they just sit in grooves and easily fall out of place. I tend to be reluctant to use petroleum based products on rubber but I know that these o-rings are made of oil resistant meterial.

BodybyFisher Posted July 11, 2008 Report Share Posted July 11, 2008 Nitrile I believe.

I forgot to add that there's nothing wrong with using Nylog but it is hard to find locally and it is farily expensive. Petroleum jelly works well for holding o-rings in place in situations like the oil filter adapter.
