    I checked out the EGR web site and I failed to find much if any difference between their product and GM's. The GM unit I bought was no drill and didn't have any rubber blocks.

    The EGR fender flares were pretty cool...

    To all triplets owners, Consider changing tire sizes when you get your next set. 255/60-17's are optional on Bravada's and worth it in my opinion.
    They are a little wider than stock and just a little smaller in diameter, not enough to make a difference in speedo readings. There is a decent selection of performance tires in this size, although stick with the standard size for off-road type tires. I know I will change when my Envoy needs tires.

    I've seen a few TrailBlazers with amber lenses on the leading edges of the roof rack rails. Are these roof marker lamps? Why do some vehicles get these?

    Anyone notice a smell of burning rubber/brake smell/exhaust smell coming into the cab of the TB on occasion with the windows down or up? Its hard to put an label on it, maybe oil? I was wondering if anyone would concur? What the heck is going on!!!

    The roof markers you see are for the Trail Blazer Northface Editions. The NF editions hit showrooms this past spring I do beleive. If you saw the roof markers, you may have also noticed the color keyed exterior mirrors as well? Also, the NF edition has recessed headlamp washers that look pretty spiffy.

    IMO.. they can keep the roof markers and give me the color keyed mirrors instead.. no need for headlamp washer's, my Enovy already has those, but would definitely like the color keyed mirrors!

    The North Face also has different two tone paint. The lower color consists of a large fender flare that covers a little less than half of the door.

    "To all triplets owners, Consider changing tire sizes when you get your next set. 255/60-17's..."

    Maybe those triplet owners with 17" wheels. Don't think those will fit too well on my 16" wheels. And, that's only about 1/2" shorter sidewall, and only 10mm wider than what is already there. (245/70-16)

    If I ever do find a set of 17" TB wheels for sale on eBay etc LOCALLY though, I might just do it anyway. (All I have found so far used take-offs are about $100 in shipping charges away)

    If I go from the sock 245x70x16's to 245x75x16's will it throw off my speedometer enough that I should get everything recalibrated?

    I would like to transport a canoe (abt 100lbs) on the roof of my 2002 TB LS. Any suggestions? Is there a cheap way of insuring no damage? Must I use a aftermarket roof rack system?

    Any advice would be greatley appreciated.

  • tblazedtblazed Posts: 945
    Going from 70 to 75 profile tires will increase the overall diamater about 1". It would make your speedometer read about 3% slower than you are actually going. At 70 mph the speedo would read about 67-68 mph. You would also rack up about 3% fewer miles on the odometer too so your calculated MPG would appear to go down a little. The PCM would have to be recalibrated by a dealer to correct for that error unless Hypertech comes out with a programmer someday. I doubt the dealer could do that. You would just have to live with the slight error most likely. ("Honest, officer- it's these darn bigger tires making me think I was only doing 7 over the speed limit!")

    Just got the notice on the extension of engine warrenty for cylinder sleeves cracking. Now have 65,000 miles on the LT. Anyone been unfortunate with this problem? I really havn't seen much in the posts.
  • steveotoysteveotoy Posts: 2
    Have 5000 miles on my 03 Envoy. Have been die hard Toyota since 1987. So far we absolutely love the Envoy. I am suspect on long term longevity of the vehicle. I have been reading these posts for six months now, and it amazes me as time goes on I develop the same problems that are posted. Went through the A/C pressure switch problem. Seems to work excellent now. The wind noise is terrible at high speeds and the dealer says their is no fix. Why would GM allow this on such a fine vehicle is beyond me? I seem to recall complaints of a squeak from the left front area? My sets up after driving about 30 minutes or so. It is primarily on choppy roads. It is loud enough, that I can hear it even with the stereo turned up. As I figured, my dealer says no one else is having the problem. Since it only appears after the vehicle has been driven for 30 minutes, it may be hard to isolate. Has anyone else had this problem, and if so, what was the fix? THANKS

    Get a rack. They aren't cheap but they work. Check for info on Thule and Yakima stuff.

    Foam blocks will work but I don't recommend them. They can slide around and tend to get lost.

    Whatever you do, please tie the canoe to the racks and then tie off the front and rear painters to the bumpers as a fail-safe.

    tb4me, do a search- enter "cylinder sleeve" in the "Search This Discussion" above and I think you will find quite a bit. Seems like most of the failures were actually built before 7-01 so that makes me feel a little better since my TB was built 11-01. Hopefully the late '01 built 4.2s were fixed by then. So, those of us with the late '01 built '02s AND the warranty extension come out pretty good, I think.

    Anyone have experience with the Coil-rite air spring setup? There's a kit for TB/Envoy:
  • tblazedtblazed Posts: 945
    Looks like that just increases the load capacity. It would be nice to add a levelling system to lower the hiked-up rear end with no load. .

    N7DON.. an amateur radio call sign? Whatever you do, don't mention putting a radio in a Trailblazer! Thought I would never hear the end of it! ( Works fine BTW)

    GM scored pretty high on this. Without the triplets, they'd probably be in first place. x.htm?cnn=yes
  • richlavoierichlavoie Posts: 56
    Pretty good for GM.

    I have read the posts and yes, lots of problems have been reported here. However, I am starting to believe they have sold quite a bit of these trucks. I see more and more on the road.

    3000 Km and no problem yet. Touch wood. The alignment is still off, but i getting the idea that this is a tire problem. I will get it fixed next oil change.

    Love (and I mean love!) this truck. The windvisors are great; I do believe they make quite a bit of difference on wind noise. The look of this vehicle is absolutely fabulous, according to my friends and neibours (and me!).

    If GM works on fixing the problems and making this truck reliable, they will sell quite a few of these.

    I know not to use the old type "normal" coolant (yellow-green) in my Envoy. I haven't seen any leak, but I noticed the coolant level in the overflow reservoir is down about an inch from the "cold fill line", so I'll top it off. Is there any problem with using a non-GM brand such as Havoline as long as it meets Dex-Cool specification? In other words, any problem with mixing two brands of Dex-Cool type coolant? Have others of you had to top off the coolant? Did you buy it from the GM dealer or another brands? My coolant looks "pink" rather than "orange" that others have described at times. I still don't plan to go the entire 5 years before replacement. Guess I'm old-fashioned :)
  • What type of window visors did you buy? I am looking to hear from anyone that has EGR brand window visors or bugshields.

  • richlavoierichlavoie Posts: 56
    I have the GM ones. The funny thing is that they put them wrong and it looked awful. I bouth the car at a different dealer because his sales department was better switched on. I brought the truck to my closes dealer last week and their service is excellent. Wished i had bought there, but it is the cost of employing imbeciles in the sale depart... In anycase, they fixed them easy and now they look fine. I do admit that I hate the idea of using tape. Try this link for info on AGR:

    I must admit that these look better then GM's. But I like it simple.

    I know there are some people here that have remote starters. Just wondering if anyone has had any problems with having it installed in their Envoy and what brand is recommended...
  • quickdtooquickdtoo Posts: 266
    I believe that Weathertech makes the EGR window visors. Here's a link to the MacNeil site that sells them. Well worth the extra $$ over the VentVisors GM sells. p;make_id=11&year_no=2002&veh_id=705&veh_opt_choice_i- d=0

    Well, as many here may have noticed, I've not been nearly as active here or on my site as I used to be. It's been really fun and the LTZ a joy to have, but sadly I've decided to part with it for another ride.

    I'm also open to anyone who wishes to take over any web site material that I have if it should prove helpful or useful.

    I potentially have my ride sold to a Dealer on Trade or if that for some reason isn't as strong a move, I also have a private buyer interested. Perhaps as early as next week I'll be back to a sport sedan.

    Thanks again for the great place, information, support and friendship to many.

  • What does a vent visor do exactly? Don't laugh :(
  • aldan93aldan93 Posts: 202
    Tires, tblazed, have you seen the new rims on the dealer lot lately, a shadow effect within the wheel ,skinnier spokes for newer TB's, very nice

    GM quality, I would say 90% of our complaints are due to suppliers to GM, not GM, except, stamping body panels, powertrain<---engine only, the rest is all tier 1 supplier issues, Delphi<---AC, Drive train American Axle, Electronics are from all tier 1 suppliers, Interior is Lear, Glass is GM, so they need to start getting tough on them!!! Hold them all responsible! I know they do, but it is cheaper and more productive, to send crappa out the door defective, then fix! Dealers and us consumers are the Quality control, I won't get into lean manufacturing concepts Toyota uses, because it would cost GM 100's of billions to upgrade the plants!, And I will never buy with my American Money, to help support Foreign GDP!!!

    tblazed.......... actually the info on the coil-rite air springs came from Bilstein sales. Apparently they don't make the load leveling system, just the shocks. Coil-rite is a Firestone product and it appears they also have the load sensing valve, etc to install a self leveling system. I'm going to make a few trips with the popup camper to see if the rear sags too much. If so I will try just the coil inserts and manually inflate.
    Yelp... N7DON is my ham callsign. Looks like putting a radio in will be a challenge. I've got an older Alinco with a removeable face that might be doable. I'd be interested in your experience(s). With the mountain top repeaters in Arizona I can cover half the state with 5 watts or less. Ham related info can be sent to without distrubing the disinterested. Hi Hi!

    Hmmm.. read your post and one thing comes to mind...

    Pontiac Vibe and Toyota Matrix... Buy American eh? Don't know if you are familiar with the latter two vehicles, but if not, check them out. They are pretty much identical and also known as a joint venture between GM & Toyota. Personally, I do not think that in this day and age you can honestly buy "American."

    Lets not forget that GM is preparing to build an new engine plant over in Japan... Also, let's not forget the many ties GM has in "joint-ventures" with many of of foreign automakers (i.e. GM/Toyota). I can even remember my grandmother buying a 1988 Pontiac LeMans that when you opened the door, had a stamp that read "Made in Daewoo Korea!"

    Just food for thought.. but at this point, unless you are building your vehicle yourself, you are definitely vulnerable to having a "foreign object" on your vehicle someplace!

    Also as I am a young consumer, I have been buying "American" since I was able to secure credit. Needless to say, that I have owned many GM, Ford and Chrysler products. I can pretty much guarantee by 100% that my next vehicle will not be a GM, FORD or CHRYSLER product. I want to become a diverse consumer, therefore it's time to give another auto maker a try! I want to experience owning a non-american vehicle to see what all of the hype is about. Will it be more reliable, will the service department treat me like a human being, will the Lexus dealer have red carpet to walk on when I take my vehicle in for an oil change?? <SMILE> Heck.. if I can get my 03 Envoy paid off in a year, I got my eye on that new Nissan 350Z sports car!

    Hmmm... Wondering if that's what Tlauro's getting???

    Congrats on your new automobile adventure. You sure will be missed via this website. Thanks for bringing us news and helpful resources concerning our triplets over the years!

    Most IMPORTANTLY... Send me an e-mail Tim.. I may have some helpful information for you concerning selling your TB.

    Just to let you all know, I was successful at selling my aunt's Trail Blazer but due to a technical glitch in one of the selling services that I utilzed, the ad was published late and also published FOUR times!

    My phone rings at least three times a day for this vehicle! I never knew that a used TB would be so popular! Too bad I don't own one personally to sell again, heck I might be able to make a real profit off of it since I continue to receive phone calls over a vehicle that we no longer own!
