    I don't have the tire pressure sensors on because they don't fit on my new wheels, so the orange light is always on... Does anyone know how to turn this off?
  3. fuel pressure gage - anyone have one installed?

    2004-2007 Cadillac CTS-V General Discussion
    Hi guys, I see fuel pressure gages online for our car. It states they install right to the "end" of the fuel rail. Would this be the end of the fueal rail looking at the engine on the driver side? There appears to be a threaded cap on the end of the factory rail. anyone have one installed...

  5. ACM Codes cleared and system holding pressure, but ACM codes keep coming back!

    Cadillac DeVille 1985 to 2005 including:1985-1992
    As the title would suggest, I cleared the ACM codes, turn the AC on high and filled it using a charge kit from an auto parts store. I do not think the system has any leaks because I am not losing any pressure but the ACM code for Low Refrigerant keeps coming back and shutting off the...

    HT4100 4.1, 4.5, 4.9
    I was driving my 93 Eldorado yesterday and noticed that the low oil pressure - stop engine light was on. I pulled into a parking spot and turned off the engine.

  9. Oil Pressure Light + Warning

    Northstar Engines and System Technical Discussion
    So coming to work today I got to sit in lovely traffic for almost an hour. About 20 minutes in I noticed the pressure light start blinking as the car would roll to a stop, stopping making the light stay on. Figured it was the switch because it has happened before and there was nothing to worry...
  10. 95 deville a/c low refrigertant true, or possibly a bad pressure switch?

    Cadillac DeVille 1985 to 2005 including:1985-1992
    The a/c in my cadillac is no longer working. I just fixed it last summer, and it did sit for 2-3 months. Once I got it legal again, and everything I recharged the a/c because it was like it lost the freon. But, it only took 1 can to recharge it. Now, just this past week everytime I go to turn...

    Cadillac DeVille 1985 to 2005 including:1985-1992
    I have a 1994 STS northstar. I had to replace the starter but found after doing this job that the fuel pressure regulator was leaking around the base of the unit just where it goes into the plastic base. I have had it off a number of time to reseat it with no luck. Below the pressure regulator...

    Hello everyone, I need to replace the power steering high pressure line that runs from the back of the pump, down the passenger's side of the engine compartment and across the frame rail to the rack on the driver's side. It has rusted through where it crosses the frame rail and hemorrhaged...

    2009-2015 Cadillac CTS-V General Discussion
    Was wondering what is considered "normal" oil pressure for these engines both at idle(hot) and at cruising speed(2000 rpm) ? Anybody noticed what their gauge display reads?
  15. Low Pressure Switch on A/C Gone Bad

    Cadillac DeVille 1985 to 2005 including:1985-1992
    In all my years working with auto A/C, I had never seen a lo pressure switch go bad. Saw one today... On a friend's car. Guess I shouldn't rule them out as the possible culprit from now on. FORTUNATELY, they're easy to check !
  16. '98 STS A/C low pressure valve location.

    Cadillac Seville / Cadillac Eldorado Forum
    Hello all, I have searched the forums for this but can't find the answer. Where is the low pressure valve for re-charging the a/c in a 1998 STS? There are two valves on the high line, but I haven't found the one for the low line. I tried searching for a diagram on Google, but no luck yet. I've...
  17. Fuel pressure questions

    2004-2007 Cadillac CTS-V Performance Mods
    I'm new to the whole return-less fuel system, I've always had a regulator on the return line on previous cars. My question is, how do our cars control fuel pressure? Is there a regulator in the tank or feed line somewhere, or is it electronically controlled by voltage to the pump? This weekend...

  20. 95 ETC No oil pressure

    Cadillac Seville / Cadillac Eldorado Forum
    As the title says I just picked up a 95 ETC with a Northstar with no oil pressure. It is not the oil pressure sensor as there is no oil reaching the top of the motor. Here's the story, after being driven normally for about 30 minutes it was parked (with good oil pressure). Then, hours later...
