    how do I get at the oil drain plug

    Hi,
    this sounds like a stupid question. with all the covers under the 2011 sts which one(s) do I need to remove to get to the oil plug. also, the filter is also puzzling me, is that the aluminum cylinder to the left of the engine? it can be changed from the top?

    thanks

    assuming you are talking about the V6, yes it's the metal cylinder, it's called internal filter and to be honest it's stupid.
    and please please DO NOT BUY fram, fram filters sucks, specially the internal ones, it got imploded in my car in less than 3000 miles, I switched to wix filters o'reilly auto parts have them.
    as for the lower cover, I dont know sorry

    Re: how do I get at the oil drain plug

    I kind of like the cartridge filter (though a little miffed that the cartridge is as expensive as or more so expensive) than a full 'can' type filter (with a can, spring, gaskets, etc). The ease of change, and the accessibility, make filter changes a breeze. My '06 didn't have the windage (undercover) so the oil drain plug was easily accessible (so no worries). Since my '11 though, I'll have to figure out how to gain access for oil changes (currently I'm still under Cadillac maintenance (free)) so haven't been under the car to check (yet).

    The rear most cover is the one to remove (4-10mm screws) to access the oil drain plug. I also like the top mounted filter.

    Thanks to all!
    I forgot to ask... how do I reset the maintenance menu thing after an oil change?

    @ your DIC, scroll to the engine oil life and hold the reset button for few seconds.

    Never use the drain plug. I use an electric pump thru the dipstick hole. Everything is done from the top of the engine. I use Mobil1 filters or sometimes K&N.

    I just bought a 2008 sts 6 AWD and plan on doing my own oil. You say do from top? Filter also?

    ^ Jim: the filter is at the top, the metal canister, but the drain plug is at the bottom of the engine, you can get one of these pumps and suck everything from the top too.

    Re: how do I get at the oil drain plug

    I searched the STS and CTS forum when I did the first change on my 2007 STS V6 AWD. There are a couple of threads with pictures. And then just to make sure I checked gmparts.com diagrams to confirm. If you don't use the pump, there are two different crankcase pans, one for rear wheel drive and a different one for AWD. Rear wheel drive plug is on the right rear of the pan. AWD is on the front left of the pan.

    Our STS's sit lower than CTS, so I had to run mine up on ramps. Some have used a floor jack, pulled the tire, lowered the car to level, and then drained. It depends what kind of catch pan your using. Mine was to high to get under the car.

    The canister filter is very easy to change and the least messy compared to the 'can' filter. It's self draining, no spillage. Just unscrew with a socket, pull it straight up and slip a towel/rag under to catch any residual drips.
