  1. Each of these can be researched on Google....Just a short list to check out... Lots of the 'GM' brands are now being out-sourced out to China. Lots of fake / counterfeit / bootleg Chinese parts. AC Delco and Delphi are just 2 examples. Fake oil filters and spark plugs. RockAuto is listing and selling Bosch parts as OEM Delphi parts. Using Delphi pictures and part numbers. Bearings? Good luck finding one actually Made-in-the-USA.... www?....it is the wild wild web out there.
  2. Found my pic on Google......rubber coupler in red circle. It will look brand new from the top...be.rotted on the bottom.
  3. Maybe eBay? You may have to have the hose custom made. https://www.ebay.com/sch/i.html?_odkw=1994+Eldorado+ac+line&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X1994+cadillac+ac+line.TRS1&_nkw=1994+cadillac+ac+line&_sacat=0
  4. Ummm.....you do know about the intake rubber plenum that leaks causing 171 and 174? They leak at the bottom where the intake juices collect....cause 171 and 174...and surging. Cadillac only part. About $20. Intake has to come off to replace.
  5. Some MAF sensors can be cleaned if you are very careful. They can also be easily damaged and require replacement. If the throttle body was removed. Chances are you will need a new O-ring gasket. They swell and are impossible to reuse.
  6. It is the nature of most aluminum blocks. Pulled head bolts threads can happen. Toyota 2.4L aluminium engines have a huge problem with pulled threads. So it is not just a Northstar issue. Time-Sert kits are available for both engines to fix pulled threads. Both repair kits are available as rentals. It is interesting to note that both the Toyota block and (most) Northstar blocks use the same head bolt thread. M11 x 1.5.
  7. Contrary to what you may have heard.....there is no Federal law regarding how long parts must be made available. That said...GM does try to keep parts available for 7-10 years. They do better at it vs. some of the newer auto makers. You should have no worries about parts being available. GM really does not make parts like they use to 50 years ago. They seem more interested in building the powertrain and the body-in-white. Many parts are made by outside suppliers and are shipped to the line just-in-time. Even body color trim comes into the plant already painted and ready to install for example. Headlights, grilles, seats, wire harness, carpet, radios, clusters, glass, sunroofs etc all get shipped in ready to bolt to the car. Some operations....like doors and wheels and tires are sometimes built by outside suppliers right inside the plant.
  8. Kind of a old design engine....not exactly a purring masterpiece. Certainly noisier than a Honda or Lexus. Having had 2 of these VUEs in the past....you kinda develop a ear for when everything is running and sounds ok.
  9. Personally I prefer using a scan tool. Anyway....It may make more sense if you think of the engine as 2 different 4 cylinder engines attached at the bottom. Each bank being 1 of the 4 cylinder engines. The computer is thinking....huh...they should both be pretty close in readings. But that is not the case with this code. Also on the chart (Figure 9 above)....ECON is the right bank O2 sensor. DE FOG is the left bank O2 sensor. Likely a sleepy O2 sensor.
  10. Been there....getting close. I did look up the name of the aluminum bracket in the GM manual....has a high tech name...'timing belt tensioner bracket'. Did you dismantle the pumped up intake valve lifters?
  11. I don't know the official name of it....but there are 2-3 versions of the aluminum bracket with the 2 pulleys. It should also be noted....there is a misprint in the Saturn / GM service manual. In some the main tensioner directions and picture will not match the vehicle. If you find that to be the case try looking up a 2001 Catera....whola...there it is. I think the NAPA current version of the replacement tensioners includes a adjustable lower one....in order to facilitate the two versions into one part #. And some belts have paint marks on them.....2 sets of marks...one set for early version....second set for latter versions.
  12. It depends on the year of the engine. Early engines did use a eccentric lower pulley. The engine pictures above show a engine using a eccentric lower pulley. Later engines...after about 1999 or 2000....that lower pulley is just a running pulley on a bolt and bearing....no adjustment possible.
  13. Sorry....was out of town for 4th... The engine is a 54 degree block design by Opel. Iron block with aluminum heads. It is used in multiple car lines in Europe. It is used in the US in the Cadillac Catera, CTS, Saturn VUE and L series. 2005 Saturn L series was the last year used in the US. https://en.wikipedia.org/wiki/General_Motors_54°_V6_engine The intake and exhaust cams are different. From GM service manual.. "Important: • The intake is marked with the letter A. • The exhaust is marked with the letter E. " Typically....if the timing belt fails or slips. All the intake valves will hit the pistons. The exhaust valves are smaller and do not hit the pistons...(on 3.0L....not sure about 3.2L..). The pistons survive no problem. You need tool J-42069 for the timing belt. You also need Kent Moore tool J-43963 to compress the valves. You need new head bolts as they are TTY.
  14. Been out of town..... Anyway....this is what the GM service manual shows for Cali certification... "If your vehicle is certified to meet California Emission Standards, indicated on the underhood tune-up label, it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected."
  15. I'm not quite sure what you are asking.. Here are a couple of 1987 Allantes from eBay.....each has a VIN # listed. http://www.ebay.com/itm/1987-Cadillac-Allante/142416964119?_trksid=p2045573.c100033.m2042&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D44883%26meid%3D76d0995a5e0041a699d025fb0c720af3%26pid%3D100033%26rk%3D2%26rkt%3D7%26sd%3D152593249982 http://www.ebay.com/itm/1987-Cadillac-Allante-Loaded/152593249982?_trksid=p2045573.c100033.m2042&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D44883%26meid%3D76d0995a5e0041a699d025fb0c720af3%26pid%3D100033%26rk%3D1%26rkt%3D7%26sd%3D152593249982
