GM's triplets Venture, Silhouette, and Montana

    They had it for a week, we got it back and now it's in the shop again - the gear-lever doesn't line up properly, and the shift interlock doesn't work (so you can pull it out of gear without pressing the brake).

    I'm enjoying the rental Grand Caravan, perhaps too much!

    I am looking for any info in regards to the power passenger side door, as far as recalls and TSB's go. My door for the last several months would not close on the first try about 35% of the time. It would get 99% closed then stop and reverse. I did not worry about this until today. My wife told me that today on her way home from work the door spontaneously opened while driving on the freeway. Happily my kids were not with her at the time. Now I am seriously concerned about the safety of the door. I would like to arm myself with all the TSB and recall info before I go into the dealer. Thanks to all for any info.

    02 and 03 Recall to replace motor . Door opening on its own might be latch needs to be replaced or aligned. Seems everyone I have talked to that the door opened on its own the latch seems to be the problem. I have had both done to my 02 Venture. Latch due to opening on its own while driving, Motor was recalled for defective cable. Door sometimes will stop in midstream except when at dealer. Check with your dealer for your year about recall or repair. Dirty contacts, dirt in tract, misalignment will cause problems also.

    Go to: - fm and search for your vehicle. The full text of the recall is there.
    NHTSA # 01v06700 was the first and
    NHTSA # 01v26400 was a recall of the recall, if I recall.
    Never had a problem with the power door on the 98 Montana. On occasion it will forget it's a power door and must be opened/closed manually. The next engine start it works. There's actually a procedure in the owners' manual on resetting the door but I've never had to resort to using it.
  • Keep in mind, if you are concerned about the door, just shut it off and use it manually.
  • I have a '97 pontiac montana(82k) that's making a rattling noise that's seemingly coming from the front of the engine. I've had water pumps make this kind of noise on other vehicles, but I'm not sure on these Montanas. Does a failing water pump on these vehicles make a rattling noise? I've also developed the infamous "Tick At Start Up." Also, I'd appreciate hearing from anyone that's done the lower intake gasket themselves.(Degree of difficulty etc.)

    "I'd appreciate hearing from anyone that's done the lower intake gasket themselves.(Degree of difficulty etc"
    Changed the lower gasket on a 98 Montana w/97K miles about 2 months ago. The leak was small but visable. The project was more tedious than difficult. The engine has to be rocked forward to give more room to get to the rear area. Push rods have to come out. Every assy and connector has to be removed. You'll need a couple torque wrenches and an assortment of metric/English sockets/wrenches and extensions.
    I'd recommend using the latest release GM gasket and coated bolts. I used Felpros. They looked like the OE gasket. The new release does look different.
    While you have the upper manifold off, the alternator will come out by removing the wiper arm. The thermostat can be replaced. You can check the rear plugs.... you can get to the upstream O2 sensor.
    Fortunately I had access to a service manual that gave me the "courage" to tackle the job.
    If you decide to DIY, email me off-list and I can send a photo of the chain I made to hold the engine rocked forward plus any other tips.
    A comment on the cold start tick. Not sure why but after changing the gasket, the intensity of the tick was lower. Also mine seems to get worse near the end of the 4000 mile oil change cycle.

    Refer to msg# 679, 685, 687, 690, 692, 713, 736.

    The 00' Silo 37K miles loud tapping noises last longer, up to 60 secs, when startup cold in the morning. Took to the dealer, let it sat overnight, they can hear the noises.

    The dealer tried replaced the lifters but the noise didn't do away. They disassembled the engine and determined excessive clearance in the piston areas, that the engine required rebuild or replaced with a factory rebuilt. GM Tech came out inspected the engine and approved for a engine replacement.

    The rebuilt seems to doing fine so far. It cames with a three years and 50K miles warrantee.

    I do have GM Major Guard extened warrantee, this has helped a bit, I think.
  • Hope your rattle isn't like mine...

    What I thought was a bad water pump turned out to be the transmission pump disintegrating to the tune of $1800 for a rebuild...

    Mechanic said he had seen several like mine.

    Sorry to hear about your tranny Mickey.
    I have a problem with my wipers. They want to shut off in the full upright position. I'm hoping tommorrow they reset themselves. I have 96000 miles on my 98 Venture, seems to be doing ok.
  • catamcatam Posts: 331
    I took my van inot the dealer today to have them finish up some work. The drivers side power window had its second motor replacement done. The power pass door latch was replaced and rear brakes were replaced along with a wheel cylinder. All of the work was done under extended warranty, my cost was $200 after $50 deductible on the ext warr and one part that wasn't covered. Total bill was just over $1000.
    I have never been a fan of ext warr, but I got a screamin deal on it when I bought the van and this is the second time I've used it. First one was replace the A/c condenser to the tune of $800. So far I have saved about $500 by having the warranty. Guess I got lucky, if you want to look at it that way.
  • tomekktomekk Posts: 310
    Is your extended warranty through GM / Chevy, or you used a 3rd party? If so, then which?
    Thanks in advance
  • catamcatam Posts: 331
    My ext. warr. is from Mastertech sold through the dealer where I bought the van.
    I didn't really research it before I bought the van because I wasn't planning on getting one.
    I got it for 2 reasons: First it only cost me $800, (I am a lifelong friend with the GM of the dealer so he sold it to me at the dealers cost.) Second, the warranty has a clause that stated I would get 90% of my premium back at the end of the warranty if I did not use it. I figured I couldn't really lose with those terms.

    thank you for the info
  • offhamoffham Posts: 344
    Noticed recently a distinct flickering of the dashboard lights when starting out with the lights on. After about 10 miles stopped doing it.

    Could this be the alternator, voltage regulator or battery - still orignal.

    Any ideas would help, before I go to the shop
  • jeberjeber Posts: 91
    anybody have a roof top cargo carrier that they would recommend. My silo has a factory roof rack.

    It appears from a brief google search that these things can go for upwards of $500 + (too much for me) but there is a "Thule Sidekick" for about $200 with shipping...I know Thule makes decent ski/bicycle carriers.

    I don't need a huge one, but do want one of the aerodynamic wedge-shaped rather than a big square-ish box. thanks in advance!
  • n7donn7don Posts: 188
    We've had a Thule "Weekender" (think that was the name) for 3 or 4 years. Got it locally at REI. Don't recall cost but in the $200 range.
    It's still in good shape.
    No additional wind noise. I did make my own mounting cross bars so it doesn't sit as high off the roof as the commercial cross bar units.
  • kkollwitzkkollwitz Posts: 274
    I bought the boxy kind you don't want for about $100. If it matters, I don't notice any change in mileage when we use it on our Venture. I think maybe the front of the van shoves air so rapidly up & over the roof that the carrier occupies a low-pressure area & doesn't cause much drag.
  • jpc47jpc47 Posts: 62
    My air bag light is on. Any ideas as to what or where the problem may be?
  • ronsmith38ronsmith38 Posts: 228
    Try moving the driver seat back and forth. Search for other instances of this problem in this and other GM Minivan forums.
  • Try looking under the driver seat. Sometimes the connections can come loose by being kick or jolted. It happened to me several times
    when the kids put their feet under the seat.
  • jpc47jpc47 Posts: 62
    tried that very thing and it worked at least for now. thanks
  • pete14pete14 Posts: 11
    Two years ago I was in the market for a roof top carrier for my Silhouette. I too looked at the Thule and the boxy clam shell version. Then asked myself how often am I going to use this and what modification have to be made to the roof rack to make them fit. I don't mind drilling a few holes for the bolts, but when the bolts are removed will the holes make a whistling sound?

    I ended up with a soft case bag type. We packed it full and drove 2400 miles. The rain never entered the bag even at 75+ mph.I placed a mat between the bag and the roof, so as not to scratch it, and off we went.

    Did not notice it at all during the drive. Plus when we got to our destination it was easy to take off, so you don't look like a tourist.

    Friends have borrowed it too and they love the fact it did not leak and was easier to use and load than the clamshells.

    One piece of advise on the soft bags is don't go cheap. You know what the saying says. But ours was under $80 and is easy to store when not in use.

    Just my 2 cents.
    Good luck

    Don -

    I'm also a doityourselfer.

    While my Van of 98k miles is not leaking badly, I only smell coolant occassionally and refil quarterly, I can see the day I'll need to do this repair.

    One concern I had was using the proper gasket and technique to avoid having it happen again. If the factory stuff leaked, I guess the new gaskets are designed better? What type did you use?

    I'd like to get some pictures of the project. Doesn't seem hard but there sure are a lot of parts that have to come off. I also need to replace my spark plugs, so tipping the motor would seem like a good thing to know about doing.


  • n7donn7don Posts: 188
    I'd recommend using the new GM release gasket. There's GM Tech on the Pontiac news group who posted a picture and it is different. If I can find the posting I'll email it to you but it was a month or so ago.
    I used a Felpro gasket that looked like the one that came out of it. At this stage I'm not going to worry about it. The Tech also said GM had released a new coated lower manifold bolt, along with the new gasket. One of the theories was the bolts would back out with thermo cycling.
    If you want to email me off forum, I'll look up the p/n's of the new gasket, which I belatedly found!! Plus can outline the steps I took.
    I found the ng posting:
    "There is a visible difference. Here's a photo of the two gaskets, new one
    is on the left, old style on the right.

    The difference can mainly be seen in the addition of two metal pellets
    embedded in the gasket around the outer bolt holes. This is so that you
    can put more torque on these four outer bolts. The rubber embedded
    gasket has changed color, whether this actually means anything is
    beyond me. When GM makes changes, they very rarely go into the
    technical data of what exactly they have changed, so you rely on what
    you see visually. Torque on the new gasket is still 15 ft/lbs for the
    inner four bolts, 18 ft/lbs for the outer four bolts. There are now
    new bolts available too, these come with the loctite already on the
    threads from the just install them and follow the torquing

    thanks to all for the info...not familiar with the soft ones, but will check 'em out. Definitely would rather spend 80 or so bucks, rather than 200, on something I'll probably only use a couple times a year.

    Also, wasn't aware some require drilling - that's something I would rather not do
  • catamcatam Posts: 331
    I saw one one the soft ones at WalMart over the weekend just browsing thru the automotive dept.
    I believe it was around $69. My first thought on it was "yea right, get where you're going and dry everything out."
    I guess maybe they may be better than that, if people who actually use them report good results.
  • One more question. Do you know when the new Ventures got the new (ahd hopefully improved) gasket? I bought a 2003. I am wondering if I should anticipate the gasket leak. Thanks.
  • n7donn7don Posts: 188
    TSB 03-06-01-010 which deals with the new gasket was issued in March, 2003. The 1997 -2003 Ventures is one of several vehicles included in the TSB.. don't have any info when the new gasket actually went into production vehicles.

    for "dirkwork" the gasket p/n is 89017279
