  1. Bulging lower radiator hose

    They wear from the inside.
  2. Oil Leak Fixed - Motor Purr

    Basically, it chemically breaks down / softens the seals - see barczy01's post above for the final result. Better to stop using it now and hope for the best.
  3. Battery revisited 2006 DTS

    If the battery charge rate is insufficient when the vehicle is being driven, then the "NORMAL" parasitic draw is too much for the battery to handle when sitting for an over-niter. Once battery voltage drops to 9.6v nothing happens after that, the rule of thumb is that the parasitic draw should be no more than 1/4 of the reserve capacity of the stock fully charged battery in mA (i.e. stock battery is 120 min reserve capacity, maximum draw is 30 mA). If battery voltage is below that, reserve capacity is reduced proportionally AND max draw is reduced as well. IF your charging system AND battery are properly tested and are verified to be "normal" THEN do a parasitic draw test. One more thought for you to consider; Okay 2 thoughts 1) An automotive battery, with the exception of a deep cycle RV "style" battery, is NOT designed to be heavily discharged and recharged. Most "car" batteries will fail from frequent discharge and recharge cycles alone. Also, where you live plays a significant role in battery longevity. When I was working in the Phoenix, AZ area the heat killed MOST batteries in 2 years. In Oregon and Washington it is not unusual to see original equipment batteries still going strong after 7-10 years. 2) If you fix the car and the battery fails in a few weeks, Momma will not be happy and IT WILL be all your fault.
  4. Battery revisited 2006 DTS

    It is not normal for the charging system to vary voltage. KHE had a similar problem recently... Sorry, I didn't make that question very clear. I was referring to parasitic load not starter current draw. From what you are experiencing I would recommend taking the Deville to someone who can diagnose the charging system. It sounds like the generator is only charging the battery intermittently.
  5. Battery revisited 2006 DTS

    Sorry, I'll have to ask a few questions first. 1) Which thread(s) are you referring to? 2) Do you own a 2006 DTS? 3) Have you added any after-market accessories? 4) Have you LOAD tested the battery in the vehicle you're having the problem with? 4a) Have you tested the charging system? 4b) Is it charging more than 13 volts? 4c) How old is the battery? 5) Are the battery cable ends and bolts free of corrosion? 6) Do you have a Digital Volt Ohm Meter (DVOM) to do the current draw tests?
  6. Very true statement. Also, even though you may not feel it miss, the computer can still "detect" it. The PCM breaks it down in fractions of a second. The MIL will flash until the catalyst damaging condition is no longer present THEN the MIL will stay on steady. If the catalyst damaging misfires exceed 2 the PCM will disable TCC. Have someone with a Tech 2 scan it and verify which cylinder or cylinders is causing the code.
  7. Disconnect the battery negative cable for about 30 mins and restart the Eldo and see if it changes...
  8. My DeVille Got Hit

    I agree, best to fix the 96 and then shop for the Eldo. Too bad ya didn't live a little closer, I have an 02 Seville that will be looking for a new home soon.
  9. My DeVille Got Hit

    THAT's what I thought would happen 'cept for the part about the 02 Eldo....
  10. I suggest he spend the diag time to have it scanned with a Tech 2.
  11. Mailbag: fuel injection ahead of supercharger?

    Thanks, I was familiar with the old school SC and the EFI under the SC but I must have been locked in the closet on the FI on top of the SC. I was trying to picture Port FI. Throttle body perhaps... Quite a project from the sounds of it. Good luck
  12. The catalytic converter does not cause poor fuel mileage. Catalytic converter damage results from rich fuel mixtures, which is poor fuel mileage. If the cat is subjected to rich fuel/air mixtures long enough they will clog and restrict the exhaust, requiring catalytic converter replacement.
  13. Hmmm, I was thinking my Snap-on scanner gave misfire counts by cylinder on Cadillac too, BUT I'm remembering last time I accessed mis-fire data it was on the 2005 GMC. Snap-on advertisements even show live mis-fire data on a 2004 chevy Logan, was there a proprietary software access problem with only 2000-2003 Cadillac? If I get time between rain squalls I may hook up the Snap-on scanner to the 02 Seville... Very true statement. Also, even though you may not feel it miss, the computer can still "detect" it. The PCM breaks it down in fractions of a second. The MIL will flash until the catalyst damaging condition is no longer present THEN the MIL will stay on steady. If the catalyst damaging misfires exceed 2 the PCM will disable TCC. Have someone with a Tech 2 scan it and verify which cylinder or cylinders is causing the code. Wouldn't surprise me either.. @Logan even the 98 FSM doesn't break it down per cylinder any more, only has the P0300 misfire detected..( Sorry my bad )
  14. Mailbag: fuel injection ahead of supercharger?

    I'm not even close to Bruce when it comes to familiarity with the engine but I am curious how pre SC fuel injection would be possible.
  15. Is P0300 the only code? List them all if P0300 is not the only one. Since it is a random misfire it is possible it is a vacuum leak or other related lean condition.
  16. Sounds like a plan Keep us posted
  17. Yes, we were talking 6.0 diesel Ford. There is an update to the EGR cooler and engine oil cooler to prevent the EGR coolers from plugging and cracking and leaking coolant. Rock said he would rebuild the oil cooler, I was curious as to how one goes about rebuilding an oil cooler. Sounded intriguing to me.
  18. Hmm, I thought the surface area of the oil cooler was too small. No? - Yes? How do you rebuild an oil cooler?
  19. HeadGasket Job Done 1998/1997 Eldo

    YaY @barczy01
  20. WoW Good find too BTW. I would think, that at engine off on a hot soak it should have puddled coolant somewhere in the EGR passage or exhaust.. So if you pull the EGR is the pintle steam cleaned? On the 6.0 cooler upgrade that looks like a PITA. Are you installing the engine oil cooler upgrade also? Let me know how that goes for you. I can get a 03 6.0 F350 pretty cheap but it is puffing white smoke too. I didn't want to tackle all that. It looks REAL UGLY...
  21. 04 CTS Sunroof 1st gen or 2nd?

    Thanks Rock..
  22. 04 CTS Sunroof 1st gen or 2nd?

    If you're viewing them online you probably won't be able to tell them apart. The difference is the SUN ROOF build date ( NOT the vehicle ) and the ability to see through the sun roof panel, the second design will be 100% opaque. Also, the second design DOES NOT have a sunroof guide. I included the GM part number(s) which may or may not help you in your search. 1st Design - - Part Number 23144813 Sunshade Sun Roof Panel (TITANIUM) 90% OPAQUE) BUILT BEFORE 03/15/13 - WITH Sunroof Guide 2nd Design - - Part Number 23116434 Sunshade Sun Roof Panel (TITANIUM 100% OPAQUE) BUILT AFTER 03/15/13 - Without Sunroof Guide As a side note: If you're changing the entire unit, it shouldn't matter which design you get, either one should fit. If you're changing components it may be an entirely different crap shoot..
