  1. ISC Motor Adjustment

    Cadillac DeVille 1985 to 2005 including:1985-1992
    If that ISC motor works the same as the later ones, press on the plunger first. It should retract. When it bottoms out, then unplug it and set the gap to .030. Gap is not critical, .030 is a good ball park.
  2. '95 base eldorado alternator into '97 ETC?

    Cadillac Seville / Cadillac Eldorado Forum
    I believe the water cooled alternators where a 3 year run, from '99 - '02.
  3. Timing issues - 2005 Deville top overhaul

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Does this help?
  4. 04 deville, P0171/0174

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Run the engine to heat the exhaust system. The thermal expansion might help loosen it.
  5. 92 STS brake problem?

    Cadillac Seville / Cadillac Eldorado Forum
    I'd pull and inspect the calipers. Sounds like you have at least two that are dragging.
  6. 2000 STS. Misfire P 0300. Another attempt - again a failure.

    Cadillac Seville / Cadillac Eldorado Forum
    Every Northstar I have had (4) have idled as smooth as if it where shut down.
  7. 1998 Eldorado HVAC system air discharge vent problems

    Cadillac Seville / Cadillac Eldorado Forum
    The parking brake auto release is vacuum operated and on the same vacuum circuit. Check that for leaks.
  8. 99 Deville False Coolant Hot Idle Engine message

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Starting to sound like a ground problem. Can't hurt to locate and clean them, especially the one for that circuit.
  9. Shop arround for services ?

    Community Lounge, Introductions and General Discus
    Sounds like your mind is already made up - dealer service only. Since that is the case, use the dealer with the better pricing. No brainer.
  10. 1999 Deville level control shocks won't air up

    Cadillac DeVille 1985 to 2005 including:1985-1992
    First thing you need to do is figure out if the compressor is working. If it does, you have a leak. Spray the lines and shock bladders with soapy water and look for bubbles to find the leak. If it does not power up, then you need to check the points Sub & Bass mentioned to figure out why it...
  11. Shop arround for services ?

    Community Lounge, Introductions and General Discus
    I do most of my own service, but when I do need something done that I don't want to do, I definitely shop around and would never go to a dealer. They are overpriced on both parts and labor.
  12. 04 deville, P0171/0174

    Cadillac DeVille 1985 to 2005 including:1985-1992
    The codes in your title (P0171 & P0174) usually point to a rip in the intake plenum duct , the rubber coupler between the TB and the manifold. The rip is usually at the 6:00 position so it is hard to spot. Press on the duct near the bottom while the engine is at idle. If you hear an RPM...
  13. Anyone know where the horns are on a 1993 SDV?

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Why do you want to disable the horns?
  14. How do you program a replacement key fob on a 99 ETC ??

    Cadillac Seville / Cadillac Eldorado Forum
    Take it apart and clean the contacts on the circuit board and the rubber button pads. You might be surprised how well it will work. If I remember correctly the owners manual has the procedure. If I am wrong, then you'll have to visit a dealer, not a locksmith.
  15. Pennzoil Platinum Synthetic vs Ultra Platinum Synthetic ?

    Community Lounge, Introductions and General Discus
    You can switch back to dino oil with no problems. You are NOT stuck with synthetic.
  16. Fuel leak assistance - 1996 Seville

    Cadillac Seville / Cadillac Eldorado Forum
    I would not recommend trying to repair it. The part you need is the "fuel Rail". Recalls do not expire, so it should be replaced for free by any dealer. Worst case, get a steel rail from any Northstar at the Men's Mall. Chances are most any year will fit. Hell, you might even get lucky and find...
  17. 1995 Deville 4.9 serpentine belt keeps shredding

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Also check for a small coolant leak that might be getting on the belt. I can tell you from experience that those belts do not play well with Dex-Coll.
  18. 1999 DeVille refrig low ac off

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Might want to read these links before using a stop leak in your A/C system. It can work, but has down sides. https://mechanicbase.com/ac/ac-leak-sealer/ https://ricksfreeautorepairadvice.com/does-ac-stop-leak-sealer-work/
  19. 88 Seville overheating

    Cadillac Seville / Cadillac Eldorado Forum
    Assuming that your temperature is accurate (199°), you where not overheating. What you saw may have been "false boiling". That is the cooling system being over pressurized by a bad HG and venting via the cap. Even with no cap, 199° is well below the boiling point.
  20. Found an Eldorado - buy it or wait ?

    Cadillac Seville / Cadillac Eldorado Forum
    I could not agree more.
