    Hello, A friend of mine has an 07 sts. 3.6 LY7 and around 60k. Recently I replaced timing chains on his car as he drove about 450 mi on a set that was making some “real bad noises” and dealer verified this problem. I also ran codes before they diagnosed and came up with typical timing chain...

  5. STS Heated Steering Wheel - New Questions!

    Cadillac STS Forum 2005 through 2012
    New questions for some of you more technical gurus on this site. My heated wheel fails to turn on like many others have in this forum (no light on switch and no heat when depressed) on my 2009 STS. I've read, re-read, scoured through AllDataDYI and still can't find the answers to my questions...
  6. Random Multiple Misfires

    Cadillac STS Forum 2005 through 2012
    I bought a 2005 STS a few weeks ago. I knew it needed help, call it a rescue(well maybe). First thing I did, after checking fluids of course, was change out the spark plugs. When I did that, I found oil in a couple of the wells, so I swapped out the valve cover gaskets. No more oil in the wells...

  9. Keyless range issue

    Cadillac STS Forum 2005 through 2012
    Hi, So I have a Cadillac STS 09, and I noticed my keyless entry is not working correctly. I have replaced the switches (actuator (double switch)) on the driver side which was a mistake as this issue is still occurring. I just trouble shot the issue with my windows rolled down and slowly brought...

    Cadillac STS Forum 2005 through 2012
    I have a 2005 STS with FE1 (Self-Levelling) shocks and got myself H&R Lowering Springs for the 2nd gen CTS. I read about raising the top mount of the shocks and cutting/trimming the rubber spacer on top of the shock. What do you guys think? Thank you.
  11. STS Body Kit - Available

    STS/STS-V Parts For Sale
    I do not want to be out of line by putting this on the forum because I am not a vendor. I have had lots of inquires over the last 10 or more years since the E&G STS EGX body kit was discontinued. They quit making these I think in 2007 or 2008, and when Vogue acquired E&G in 2014, they cancelled...

  14. Dies & says no fuel with fuel present '00 sts

    Cadillac Seville / Cadillac Eldorado Forum
    I bought a 2000 Seville and did a HG replacement. Once it was all back together and good to go I made sure to add 5 gal of premium to the tank so I knew it had fresh gas. (the gauge was low/empty when I bought the car and wasn't sure how long it had sat...) I was taking it for a drive (bout...
  15. Fog Lights & Other Mods.

    Cadillac CTS First Generation Forum - 2003 - 2007
    Hey, I'm new to this forum, so just wanted to say hey. I own a 2004 3.6 L Cadillac CTS. Anyway, I was wondering if anyone could refer me to a seller who has either the Clear or Smoked fog lights for driver & passenger side. I found the side markers on ebay a-okay. Also, my bumper got damaged...
  16. Why does Cadillac hate V8 engines?

    2008-2013 Cadillac CTS General Discussion
    The CTS, especially the new coupe, is a knockout and if it had the LS3 or L99 V8 available, it would dominate the 6-cylinder competition (335, G37, Lexus etc). But for some reason Cadillac refuses to give us the V8 except for souped-up versions in the very costly V-series. It doesn't make any...
  17. Time to upgrade

    Cadillac Audio, Video and Security Systems
    I've always wanted more bass in my Cadi and now that both the front door speakers are partially blown its time. I'm thinkin new speakers all around, amp, and sub(s). I am fine with the stock head unit to keep the process a little simpler and cheaper. I have a '00 Seville STS with bose(CD...

I will sometimes have to turn the key many times to get the (service engine) light to come on so I can start the car. The car will not start unless that...
  19. 2009 STS N* RWD 1SE w/HID?

    Cadillac STS Forum 2005 through 2012
    I keep getting asked. I keep saying no. However, since my used car saleman seemed to indicate otherwise, I have to ask. Do these headlights move? That is, do they follow turning? Headlights: TT6 - HEADLAMPS, HIGH INTENSITY DISCHARGE W/WASHERS TQ5 - HEADLAMPS, INTELLIBEAM-HIGH BEAM CONTROL...

    Cadillac Seville / Cadillac Eldorado Forum
    I have a 92 STS with the 4.9 V8, and when I'm idleing at a stop light or drive thru it starts over heating. as long as I'm moving it's fine. Temp got up to 190 degrees and I started seeing steam appear around the hood. I pulled over and opened the hood and that plastic antifreeze overflow tank...
