    Oil filter cap, nut snapped off cap!!

    So I have the oil change done by the dealer last time, I go to change the oil in the filter and while trying to loosen the oil filter The nut snapped off of it!

    I called the dealer and unfortunately everybody in service has left for the weekend and I won't getting anybody on the phone till Monday.

    I'll be damned if I'm paying for it!!


    But if they're not going to help me what can I do to get the cap off and replace it?

    Re: Oil filter cap, nut snapped off cap!!

    Getting the cap of is just a matter of clamping onto it with tools and screwing it off. (if you got any super strong friends call in a favor because it will be a pain in the ass to get it off if it was over torqued on. worst case you might have to chisel it off like others in the past: http://www.cadillacforums.com/forums...using-cap.html )

    Based on this link: http://www.gmpartseast.com/Page_Prod...Code=6D1&Year= the key is 450 and part # is **583470 and should set you back 30-50 bucks.

    as shown in this other diagram http://www.gmpartseast.com/Page_Prod...Code=6D1&Year=

    the part should be the same regardless if your awd or rwd (couldn't tell based off your post)

    edit: also make sure to check that the o-ring is still in reusable condition when you remove the damaged cap and order one if necessary it's like 4 bucks key is 451 part # is **577653 based on the previous links provided. They must of torqued that thing on good for it to snap off like that when un-tightening. You can reference this faq for other information http://www.cadillacfaq.com/faq/answe...nge/index.html

    These things tend to get tighter so not sure the dealer will do anything for you, I always notice they are tighter than when I out them on last.

    If it were mine, I would put some gorilla tape on it and take it back to the dealer that did the oil change! I would also make them show me how many ft. pounds it was tightened to. Then they would need to give me a free oil change and a new filter cap. We all know that lot boys do the oil changes and not technicians.

    I just changed the oil in my 2008 yesterday and yes, the oil filter cartridge housing cap was way tight. Fortunately, mine came off with extra effort and nothing broke. You may want to try one of those old fashioned oil filter wrenches that uses a chain for the "strap" portion (assuming you can get it to fit around the cartridge housing. Good luck!

    Is it easier to remove HOT or COLD? Mine was a little tough to get off and I am thinking for the future what would be the best approach. Ice it down or apply a little heat from a torch?

    Metal contracts when cold and expands on heating, you be the judge.

    A strap may get it off.

    Rockauto has the oil filter cap, AC Delco brand with gasket, for $28 plus shipping.

    I would think hot may be the ticket to get it off then cool when it goes back on.

    Mine was tight but it felt like the face was just bound on the canister and not the threads, so I would think if put on hot as it cools it pulls the cap down a bit and it gets tight on the face.

    Tighten cool and try a bit of never seize on the face of the cap.

    3. Remove the oil filter cap with a 6 point 24mm socket and 12” extension. You might need a breaker bar. Retain the O-ring on the filler cap for reuse.
    ***Install oil pan drain plug and new O-ring seal, Tighten to 20 Nm (14.75 foot pounds)
    ***Install oil filter cap, tighten to 25 Nm (18.44 foot pounds)

    Sorry guys- I'm signed up for email notifications but I never get them!!

    I was so kissed off at the dealer- we hardly drive this car and it's been almost a year since we changed the oil, computer didn't say to do it but I wanted to change it. So when I called the dealer I explain what the deal was and the service advisor says "Your supposed to
    Change the oil once a year why didn't you?" I said "look man, were past that point, the problem is your tech over torqued the chit outta the drain plug and the filter cap housing and now it's broke!" He hung up on me!! I then called back and spoke to some other lady and she was giving me crap about not changing the oil sooner as well! I told her the same thing, that this is not about how frequent I change the damn oil and it's about your tech not properly following manufacturer instructions and specs and that I question your technicians ability to properly service any customers or my vehicles.

    I get put on hold, so I go to look at the window sticker to see if there's a tech badge number or something to identify the tech by and resliZe I got the oil changed at a lube shop around the corner. Lol I felt stupid. But, they were treating me poorly if you ask me, had a piss poor attitude and were snooty with me when on the phone, not to me room one idiot hung up the phone on me- I heard the phone slam down on the receiver, It wasn't a disconnect or dropped call.

    So I call the lube shop and the owner says they have problems with the kids getting tight like that, but offered to send a guy over immediately to get the cap off and he was successful with a 8" punch tapping around every inch or so. My dad has a dealer account with XL parts (they provide alot of dealers with their parts) so I got a new cap for $24.00 and all is good now.

    Btw I did try HVAC metal tape and duct tape- not strong enough to hold that oil pressure. Just for future reference. Somebody's gotta make a better aftermarket cap do they?!
