GM's triplets Venture, Silhouette, and Montana

  • I am not a mechanic, but do almost all of my own repairs, changing rear main engine seals, rebuilding the transmission and transfer case on my jeep, ect. My engine was overheating. I changed the thermostat and ran good for a week. It began to overheat again. I found air in the radiator system. During that time, I was getting a loud rattle as you describe. I thought I had warped heads from overheating. The Silhouette also ran rough the first 30 seconds during all start-ups. Unexplainably, after I bled the air out of the radiator system, all problems disappeared. Its been fine the last 20,000 miles. I currently have 195,000 miles on the vehicle.

    Don't ask me how air in the radiator system could cause these problems (other than overheating), but that is what happened. For all I know, the rough idle and rattle was not related to the air in the system, but unexplainably, both problems disappeared after bleading the system. Good Luck!

    Look at message #687 in this forum. I've since given our 98 Montana to our son. Pistons were replaced around 30K miles. Tick or rattle was less but eventually returned over time. Was less in colder weather. Van still running good at 132K and still rattled on startup. The info suggests the noise is because of wrist pin fit.... I recall sometime in 2003 GM released polymer coated pistons for this engine per bulletin 03-06-01-002

    The inside of the positive battery terminal was cracked causing the intermittent power outage.

    New battery, car works fine.

    I am having this problem and trying to fight with GM on it. I Don't think they care.

    Same on our 05 Relay, I was living with it, but am now on a mission.
  • My car died recently, and I ran into a 1997 Silo with 50K miles on it. The test drive was great and the van is imaculate, but there are two things troubling me:

    1. The check engine light is on and won't shut off. Is this a sign of the infamous leaking radiator fluid into the engine oil problem, or is it just an old car who needs a catalytic converter? Or could it be something else? :confuse:

    2. The ITC light was on all the time we were driving, until I turned it off., Looking at the manual, I thought I read that if that light is on it means something needs fixed in the system. Am I correct about this? :confuse:

    The price is very low, and I am not worried about it not being driven enough over the years of ownership. :shades:

    Thanks for your help!
  • Forget any Montana, Sillouette or Lumina APV! I had the same problem with my 1997 Montana.....just spent $2800 fixing it...a gasket leaking antifreeze into the engine.
    I worked 19 years at Pontiac Motors and GM/EDS, 10 of those years at the GM Tech Center in Warren, Mich. Lot's of problems with this vehicle...brakes, electrical, rattles, fuel injectors, windows, etc.. Constant problems.

  • Helllloooooo Out there!!!

    If there is anyone out there who still looks at this forum beside Jack and I, I am curious about something:

    Did all the different engines used in the triplets have the same problem, or frequency of problems, or did different engines have different rates of problems?

    For example, a sales guy I talked to about a Silo said the 3.4 's did not have a s many problems as the other engines used in the Silos.

    I was under the impression that GM standardized on the 3.4 in the production of the triplets but I might be wrong. If you had problems with gaskets going bad, tell us what engine you had.

    Thanks!

    As far as I know, all the '97-'04 GM minivans use the same 3.4L engine. All the vans were built in Doralville, GA.

    Our 2001 Olds Silo has had most of the problems mentioned on this and other forums. The 5 year/60K warranty that came with the van was very necessary! I would conservatively estimate that GM has spent $4,500 fixing our van under warranty. We have only spent $200 out-of-pocket and that was customer goodwill on a new A/C compressor at 59K miles/62 months.

    The van is running great now at 65K miles. The new Goodyear Triple Treads sure give it a better ride than the original Generals. We hope to keep another 10-15 years.
  • Correction...I have a 1999 Pontiac Montana. The only engine available on this model year was the 3.4....a piece of junk!
    Earlier Transports/Montanas had the 3.1 litre or 3.8 litre engines. I had one of each...pretty good vehicles. The 3.8 litre V-6 is considered a solid engine. The past 1 1/2 years there has been a 3.6 and a 3.9 litre available...look at Consumers Reports which rates both LOW.

  • Correction...I have a 1999 Pontiac Montana. The only engine available on this model year was the 3.4 which
    Consumers Reports rates as "UNRELIABLE Long-Term"....lot's of repairs especially after the warranty expires.

  • Which model years had a
    5 year/60K warranty?
    Did the 1999 Montana have this warranty?

    After GM announced the discontinuation of Oldsmobile in 2000, they put a 5yr/60 miles warranty on all new Olds products. That is why we bought the Olds Silo instead of the Chevy or Pontiac versions. In 2002, they gave customers the option of $1K cash off purchase or the 5/60 warranty.

    Also, the Olds was $3-4K cheaper than the highly rated Honda Ody or Toyota Sienna when we bought new in 2001. We are still $2,800-$3,800 (plus interest) ahead of what Consumer Reports recommended! As we don't plan on selling the van, resale value is irrelevant.

    Then on the right margin it will ask; "Choose Car Year". Enter the year, i.e. 1999.
    It will then come back asking for model, etc.
    I entered mine; a 1999 Pontiac Montana 3.4 Litre V-6.
    I got 3 Recalls and 148 TSBs. Click on: http://www.alldatadiy.com/TSB/49/994902gn.html

    Many people look to used American vehicles as a value play. Save a bunch by not paying for new vehicle depreciation and pay less than used comparable Japanese brands. Of course, this assumes the car you are getting used is reliable in order for it to be a good value. Herein lies the problem with the GM minivans.

    The high number of TSBs relates to engineering or design or manufacturing defects by GM and/or its suppliers when the van was originally put out. The TSBs are generally the solutions to these original defects. Oftentimes, the TSBs include new and redesigned parts. I know this is the case for our new intake manifold gaskets (2nd set) and our new A/C condenser.

    I would suggest only buying a GM minivan used if you know all the service history of the vehicle. Ideally, this would be a one owner who looked after the vehicle him/her self or had it serviced by the book at the dealer. This is not a good used vehicle to buy from someone that doesn't look under the hood frequently and instead takes it to the cheapest lube shop for oil changes.

    I have caught two intake manifold gasket failures, A/C condenser failure, A/C compressor failure, and tranny failure early and under warranty because I change my own oil and look at things on a regular basis. This is a high maintenance vehicle that does require attention.

    As far a longevity, go to Autotrader.com and type in 1997 Chevy Venture/Olds Silhouette/Pontiac Montana and you will see a lot of vans with 100K-200K miles. I plan on getting at least 200K miles out of our van.
  • Folks,

    I would appreciate your help. I am at a loss as what I should do:

    Which should I purchase:

    1. 1997 Olds Silhouette GLS, 55K, immaculate shape, most all the extras, $7500
    2. 1997 Chevy Astro conversion, also immaculate shape, 77K miles, $8000.

    The tradeoffs: $600 less, fewer miles for the Silhouette vs. high quality conversion, more plush interior and extras, TV/VCP, better engine, less possible major problems.

    Carfax is clean on both vans, both are local owners with no major repairs, and are being sold by dealers.

    I just don't know which one to pick!

    Thanks

  • Question: did GM agree to pay for any of the problems with the intake manifold gasket failures after the warranty period? They told me that they did not know of any problems or TSBs for intake manifold gasket failures on my 1999 Montana.
    Comment: on the Astro....they have a 4-speed aotomatic transmission which has been having lots of failures.

    The dealer is not telling the truth if they were not aware of the issue of intake manifold gasket failure on 1997-2003? GM minivans. The gasket was redesigned in 2003 or 2004, I believe, to address the high failure rate. So the dealer is keeping quiet so as not to point the finger at GM.

    Getting GM to help pay for the cost of replacement has been difficult for many people who had the standard 3/36 warranty. Some have gotten assistance and others have not. I can understand why many people have swore off GM after having to pay $800 to fix this problem right after the new car warranty expired. We were just lucky to have the 5/60 warranty.

    We have not yet had an IMG failure since the second set was put on in Feb. 2006 under warranty.

    I have a problem with a 1999 Venture interior door lock switches. I believe both interior door lock switches work since they will activate the door locks to lock but will not unlock the doors. The door lock motors work since I can unlock the doors with the remotes. Is this a BCM programming problem? Anyone have any clues to search for a cause of not being able to unlock the doors with the door switches? :confuse:
