    On the 1/2 ton GMC's the aux. trans. cooler is located low center of the grill. Guessing about 8 inches high and 16 wide. There is another cooler along the lenght of the left side of the radiator that is the power steering cooler. Does anyone see this on a Chevy?
  • tungletungle Member Posts: 56
    I have the GMC Sierra with the trans cooler opt. I found a small radiator like mounted in front of the engine radiator. Is it what I should look for?

    Hi jxyoung,
    Was it difficult to put those 4 big bolts back
    in? Do you have to use bolts supplied with the
    bars? Where do you put the bracket, like under the
    frame bracket and the big spacer? I look at the installation instruction and I'm kinda confused.
    Just afraid that after I remove the big bolts I
    would have a hard time to mount them back in due
    to possible shifting of the cab relatively to the
    frame brackets. Your info will be very helpful
    to me.
    Thanks,
    Tung

    I got a call from my dealer late this afternoon and was excited to hear that my truck(Chevy Silverado 4wd Z71 265's buckets Z82 trailer package)has arrived after 73 days(much sooner than we thought).

    We drove over tonight to drool on it and much to my dismay, it has arrived never mind without the transmission cooler, they missed the trailer package all together!

    The dealership was closed by the time we got there, so I couldn't talk to anyone about it, but I will be making a point of dropping in tomorrow.
    It should be very interesting to see how they're going to fix this one.

    Of the other trucks that they got in today, two of them *did* have the trailer package, and they both *did* have the transmission coolers in place.

    I'll let you know what happens
  • chevy4mechevy4me Member Posts: 203
    I have the z82 trailering equipment option ($285)
    but I can't find an aux. trans. cooler.The power steering cooler is there on the left in front of the radiator and the trans lines do go into the side of the radiator as usual . Any one else with a chevy look?
  • mksalemmksalem Member Posts: 42
    '99 Silverado 2wd extended, 5.3, trailering, Z85, etc. Build date 12/2/98 in Canada DOES have it's Aux cooler smack in the middle of the big radiator
    26andrew1 - What kind of manual seat is having the track problem - bucket or bench (or both)
  • bernie51bernie51 Member Posts: 10
    I could not find my Trans cooler either. I found my window sticker and it says its on there with the trailering special equipment option. I went to the dealers lot and inspected some of the other trucks with Trailer Pkg. and lo and behold they have a big ole cooler right in front of the radiator! I have the mounting bracket but no cooler. Makes one wonder what else they left off. Anyway back to the shop on Monday. My truck is a 4x4 1500 LS Ext Cab with all options. Built in Oshwa ontario Sometime in Jan 1999. Everything else on it works fine. It did pull to the right and that was finally adjusted. I suggest others with Trailer Pkg. check this out.
  • chevy4mechevy4me Member Posts: 203
    My truck missing the aux trans cooler was also built in Jan.99 at Ft. Wayne, Indiana.
    Does anyone know where to connect a power wire for an add on stereo amp? Is there a way to get a wire through the firewall ?
  • cornhusker1cornhusker1 Member Posts: 22
    I thought my 3/4 ton Silverado was missing the transmission oil cooler to but I looked real close and the transmission lines go to the radiator and back out to the transmission oil cooler and back to the transmission. Its tough to see but if you look close its there. The cooler to the right of it is the oil cooler for the engine. I have a total of 4 coolers in behind my grille. The Radiator, the Air Conditioning one, the Transmission one, and the Engine Oil one. I don't know if the 1/2 ton has the Engine oil one but you should have three if you look real hard for it and how the lines are routed

    For those of you in the market for a 2500, I learned a valuable lesson this weekend. I had been waiting for my ordered vehicle to come in when the dealer notified me he had a group of Silverados transported in from Canada. One them was equipped similarly to my ordered truck (2500,LS,4x4,extended cab,SWB, everything but autotrac or leather). I decided to buy the truck but on inspection realized that it did not have the A/T temperature gauge. Turns out that since the truck had been built for a Canadian dealer, the instrument cluster had to be replaced by the broker who certified the truck for US specs. Basically, when changing out the k/m cluster for the mph cluster, they failed to get the one with the A/T gauge. The correct cluster will be here at the end of next week and the dealer will change it out. Other then that snafu everything else went well. So far I'm very impressed with the truck. The fit and finish is excellent and the braking quality is the best of any I've owned.

    Tungle:
    Not hard to get the bolts in at all. Just remove the factory bolts, put the washers onto the bolts and insert them thru the bracket then up into the hole. When you remove the bolts the metal washer looking thing with the rubber shock absorber(?) may come off with the bolt. No problem Just put it over the new bolt last, just before you push the bolt thru the hole up into the cab.
    I have the extended cab so there was no "spacer tube" in the kit. The "spacer tube" comes in the regular cab version. If you look at the parts list it shows this. I assume that the old bolts would be too short and would not work or I am sure that Westin would have saved a buck or two and had us re-use the factory ones.
    Hope this helps. If you have more questions let me know. I Installed them when I was alone one day in about an hour. It is not that bad.

    the bench seat is. But the bucket I think is the same design just middle seat is missing and a console is put in. But not 100% sure on this.
  • tungletungle Member Posts: 56
    Thanks, I also have the ext. cab. What I called
    spacer was referenced as shock-absorber by you.
    I'll try it and let you know how it goes. THanks
    again. Tung.

    Well, finally towed the travel trailer beast (5,000 lb, ~500 tongue wt.) with my 1500 5speed 4.8L 4x4 4.10 this weekend. Down the 6% grade no problem, back up th 6% grade from 3,000 ft to 7,000 ft in 3rd gear, about 62 mph, ocassionally down to 55, at around 4,000 rpm.
    Only logged about 130 miles, got 9.2 mpg. A little better than my buddies F-350 SD CC 4x4 V10, but his truck weighs about 2,000 lbs more. Runs along just fine at 7,000 ft, 70 mph, in 4th gear at about 3,200 rpm.
    Pretty happy with the sub 300 cu inch motor.
    Did get some occasional ping on reg gas. Will run premium when I tow in the future.
  • markbuckmarkbuck Member Posts: 1,021
    Finally hit mine at 3,400 miles. Might just trust it in the future.
  • markbuckmarkbuck Member Posts: 1,021
    Forgot to mention in post 331 that temperature gauge didn't budge, running the A/C and running at 4,000 rpm in third gear at WOT for around 15 minutes. Outside temp was only around 75F so haven't given it the severe test of 100+F Phoenix weather yet. Will keep you all posted.
  • chevy4mechevy4me Member Posts: 203
    I went to dealer about the transmission cooler missing and was told that the vendor supplying the coolers couldn't keep up with demand at the time my truck was built (Jan. 99). So they built them without. Dealer has a bulletin concerning this. I was told that the dealer gets credited for the cost of adding on the cooler from the factory. At least one other truck had this done already. This is on a 1500 LS 2wd with z82 trailering equipment. I will update later.

    Happy with driveability though - hope it doesn't screw anything up.

    Headed to Buena Vista, Co with a bunch of coworkers second weekend of June for an enduro. Let me know if you wanna come raft the Brown's Canyon or race or mtn bike with us......

    Noise?

    I have a 99' Silverado 5.3 auto with 4,000 miles. I occasionally notice a slight ticking sound when it is lugging along at 1000 - 1500 RPMs under a load. It sounds something like a minor exhaust leak or vac. leak. I took it to the dealer and they said they thought it was just the normal sound of the injector pump. Does this seem right?
  • markbuckmarkbuck Member Posts: 1,021
    Sure it's not ping?
  • quadrunner500quadrunner500 Member Posts: 2,721
    Agree with Mark. Sounds like symtom of minor engine ping. There is no injector pump on 5.3L gasoline engine, just a fuel pump in the fuel tank.
  • quadrunner500quadrunner500 Member Posts: 2,721
    Thanks for the invitation to Buena Vista Mark. Have you ridden there before? I'm a "B" class rider on a good day. I can't maintain 24 mph for 3 hours either. But I love those single line trails around Buena Vista. I think you will too. Two years ago I helped Mike Simpson, the Collegiate Peaks Enduro promotor with some trail work, and got to preview the course. And of course, Malcom Smith has a home in the area, near Cement Creek I believe. But I have been riding those rocky horse trails, sandy washes, and old railroad grades for years now. Quite a few times helping Mike to connect the trails for the enduro into something the USFS will allow. Like everywhere I guess, there is pressure to close some of it off, every year. Sweet and beautiful though, Mt. Princeton. Later in the season, it's possible to ride just to the west in the Taylor Park area. It doesn't get much better than the Timberline Trail and Star Trail, in Colorado.
  • quadrunner500quadrunner500 Member Posts: 2,721
    My salesman told me supplies on Silverados have only gotten tighter, especially the 2500's. Because of this, they are quoting sticker prices. Said Corvettes were in high demand too, surprisingly.

    Nevertheless, I saw 4 new 2500's get unloaded from the hauler.

    1.) Some had leather seats, 6.0L, 4x4, ext cab short beds, and regular cab long beds.

    2.) The 1500's that came off the truck were Z85's but appeared to have some of the Z-71 goodies like stabilizer bar and jounce bumpers. If they shorted your transmission cooler, maybe they slipped in something else?

    3.) None of the trucks were tied down with the nylon lash straps as a previous post had stated was the proper procedure. Instead, frames were all just chained conventionally to the hauler. Might as well send them all to the alignment shop now, and spare the owners future "steering pull" visits.

    I saw info on 2000 models in "Open Road" magazine for summer of 99. Suburban and Tahoe models are getting coil spring rear suspension.Also has a small article on the new heavy duty 3/4 and 1 ton trucks. It shows a crew cab with shot box.Side air bags are also on the list of new items.These trucks really look good for 2000. Look out Ford!
  • gojonesgojones Member Posts: 15
    Had my Silverado (5.3L; 3.42; extended cab; short bed; 2wd) for one month today. Have vibration on takeoff and also occassionally at crusing speed. Took it in to have tires balanced and vibration checked. Called me later and gave me a case number for GM. Said GM engineers are working on a solution for changing angle of driveshaft. Will probably involve motor mounts or rearend shim. Does this sound logical. Will go along. Really like truck. Said no hard driving and truck will be OK.

    Been monitoring dialogue and comments for a while.
    Folks like Markbuck and Quadrunner out to be on GM's payroll for the great expertise and the amount of information they bring to the board.

    I've had my Silverado 1500 LT for three months or so, and about 2400 miles. The truck has proven itself to be 'like a rock': Solid and squeak free.
    I get a low rumbling sound at low speeds, probably drowned out at street speeds. Dealer says it may be an item that needs lubricating. The headliner behind the drivers' seat, by the window, was not tucked in properly at the factory. Other than that, wow! (what a truck!) The 5.3L got a little over 20 MPG back from Lake Tahoe last weekend. Smooooth as silk! Really can't find fault with this vehicle.

    As I have mentioned before a rear slide door would be more useable. I have seen a Sienna the had the engineering, with a grove/guide along the side of the body that didn't take much from its' good looks. No question in my mind, it is the next natural evolution in the 3 (and 4) door pick-up. Makes sense if the utility of the vehicle will be enhanced and engineering/safety issues that result from the rigidity/support present stressed members can be answered economically, and the buying public accepts the solution without having the 'mini-van image' destroy the market.
    To anyone is fooling with the idea of buying a Silverado in its' present state of dress: You're in for a treat!

    davek3,

    The front fenders on my Silverado are steel.

    Maybe you are looking at the fender flares.

    They are molded plastic.

  • tungletungle Member Posts: 56
    First, I don't know exactly how an engine ping sounds. Second, my truck engine, most of the time,
    is making some wind noise which sounds like a
    little snoring or snipping sound. Is it the
    engine ping sound we're talking about? If it is,
    what can I do to improve it? Thanks for any advice.

    An update on the wheel balance. The dealer, after almost two days, figured out that one of the tire
    had a heavy spot, so they dismounted the tire, flipped it (bringing the inside-wall out) and that
    seemed to improve the vibration problem substantially. However, I still can feel little
    vibrations; will keep an eye on this wheel.

  • g8trg8tr Member Posts: 77
    davek3,
    The fenders on my Sierra are steel. However, if you look on the inside of the fender up near the windshield there seems to be some sort of lining on the inside of the fender that looks like fiberglass. It could be there for additional support. The fender itself is definitely made of steel.
  • quadrunner500quadrunner500 Member Posts: 2,721
    Tungle,
    It's not the "snoring" or sound of wind. It's more of a metallic "clinking" or "ricochet" that is heard when the engine is under a bit of strain, or you are lugging up a slight hill, towing, or hauling. Even sounds a bit like a Ping (tm) putter if you are familiar with golf. If you have it, it will be barely noticeable, unless you have the windows up, the fan and radio down. It's most likely heard between about 35-50 mph. The owners manual, under the section on gasoline grades states you don't have to worry about it if you hear a bit of it. If you have it, it is a sign the engine is not happy. But since GM is offering a fix, it's worth listening for.
  • djstepdjstep Member Posts: 26
    Not getting anywhere with my dealer on the missing aux. trans. cooler. has anyone out there had this problem resolved. If so I would greatly appreaciate a dealers number to call and get the info I need to convince my dealer.
  • 26andrew126andrew1 Member Posts: 93
    Just point out to them that it is on the purchase order, bring it with you. Then have him show you where on the truck it is.

    Note it is NOT in the radiater
  • davek3davek3 Member Posts: 31
    hi guys..

    the fenders sure feel like glass and look like from the back.. going to give them the "magnet test" today!! i don't mind if the are glass.. one less rust problem!! I'll let ya know what i find out!!
  • markbuckmarkbuck Member Posts: 1,021
    Knowing what ping is is kinda like sex. Hard to explain the sounds until you've experienced it.
    A 'crackle' noise is close....

    Getting my computer udated with the "new calibration to address various drivability concerns including spark knock (ping), hesitation, and false dtc p0121" today. Driving 300 miles down to 1,000 feet elevation and back to 7,000 ft elevation this weekend. Will let you know how drivability and fuel economy are affected with the new software.

    Quad, rode the first several years of Collegiate Enduro, took a few years off, and have ridden it the last 3. Overalled the B rider group in 1997 and got bumped up to the A division. Not too many trophies since then competing against all the young A riders. Turn 40 next year and will finally compete in the over 40 A class. Hope for trophies. Know Mike Simpson a little, we sorta recognize each other, he doen't own the KOA anymore and they kicked our group out this year. Got to race against Malcolm Smith in the Taylor Res area (Crested Butte National) about 10 years ago. He spanked me as a 50 yr old man (when I was 30)....and was still fresh enough after the race to sign autographs for an hour.

    Planning a week or two trip to Taylor Reservoir or Summit Co for later this summer.
  • chevy4mechevy4me Member Posts: 203
    Does anyone know of a reason why G.M. wouldn't just add on the part that is missing? I was told that G.M. hasn't decided what will be done.
  • northernbassernorthernbasser Member Posts: 20
    I picked up my truck on Thrsday afternoon: 1500, 4wd, Z71, Ext, 265's...and a free trailer package.

    I posted last week that they had somehow managed to "forget" the trailer package on my factory ordered truck. I didn't get (publicly) upset about it, but rather waited to see what the dealer would do after I pointed out it's absence. They put on a Class III hitch, the factory standard harness, and an aftermarket transmission cooler.
    As a result of the omission being their fault, I was not charged for the trailer option (in the words of the salesman).

    The truck itself it great. Very tight, no squeaks, rattles or pulls. I only have about 200 miles on it (325 kms), but have nothing to complain about yet. I love this truck.
  • quadrunner500quadrunner500 Member Posts: 2,721
    I rotated my tires today at 7500 miles. Tire wear looks good. I don't know why I decided to save $10, so please don't go there. While the fronts were off, I had good access to the grease zerks, so I did a chassis lube also.

    This truck is simple to work on. I guess that's why so many owners do.
  • markbuckmarkbuck Member Posts: 1,021
    Got the new software loaded. No pinging change for the first ten miles or so, but got better the more I drove (maybe it had to learn?)

    Drove to Phx and back. No change in drivability, fuel economy, but ping is substantially reduced.

    Greasing - got two fittings on the steering linkage that I couldn't get to. Will try to grease it with the steering at full lock next time or install 90 degree zerk fittings. Any other ideas?

    At 4,000 miles, no real problems other than slight ping and pinion seals failing. Pretty happy, but it is just a vehicle to haul me around. Love the vinyl seats.
  • tungletungle Member Posts: 56
    Mark, what was the software update part# that
    you just had? Is it an update for all engine
    size of only for some specific engine size? I
    have 4.8L. Thanks.
    Tung
  • pkeithpkeith Member Posts: 4
    Does any out there have their 99 in cobalt blue? I'm strongly considering this, but is it as difficult to keep clean as black?

    Also considering pewter.

    Thanks!
  • cookie1cookie1 Member Posts: 68
    Indigo Blue, not Cobalt Blue.
    I have Indigo blue and it is the sharpest color
    in my opinion when kept clean.
    Otherwise, Light Pewter Metallic is good also
    if you do not keep your vehicle clean since this
    color shows the dirt the least of all the colors
    available. Your choice: Great looks or looking clean?
  • nowickslnowicksl Member Posts: 20
    Markbuck, I was able to grease the steering joints by turning the wheels to JUST the right angle. I tried to remove the factory zerk, but couldnt get it to budge. Next time I will try a bit harder and install a 90. I have had my truck for 5000 miles and am AVERAGING 18mpg with 5.3 4wd, and will do all of my own maintenance. I have even been afraid to take it back to the dealer for the sticky throttle and squeaky door hinge for fear of a line of bs. does anyone really have a cure for the throttle stick at highway speeds?

    Ii have a Pewter truck, and sure, it is a boring color, but the other choice I had was black, which really looks great, but I couldn't see myself washing it on a ladder EVERY DAY!
  • pkeithpkeith Member Posts: 4
    Ya, indigo blue. There's a Z71 at the dealer now with medium grey leather. It's got to be one of the nicest pickups I've seen.

    I just don't want to wash it every day! There's also pewter there with graphite leather. Also very sharp. I need to make a decision!
  • pjb0422pjb0422 Member Posts: 43
    I have the Meadow Green ext. cab Z71. I think this is also a sharp color. My first preference was the pewter but the dealer didn't have one in stock. Now I have noticed many 99s in pewter but am yet to see a 99 ext cab in Meadow Green like mine.

    Sticky throttle? Does it feel like the throttle is binding when driving at highway speeds, let off the throttle and then step back on the throttle? I had this problem. First time the dealer adjusted the throttle body plate. Cured it for about a month. The next time I took it in for the binding problem, I ended up with a new throttle body. No problem since.
  • quadrunner500quadrunner500 Member Posts: 2,721
    I love my low maintenance Pewter. Indigo blue is stunning. I believe ?? I have seen the meadow green in a GMC.

    Get the throttle body replaced under warranty. It only gets worse.
  • ajdawsonajdawson Member Posts: 16
    A couple of problems I've noticed:
    1. Wind noise at the passenger rear window.
    2. Horn sometimes doesn't honk.
    3. window switch for drivers side sticks when trying to roll up.

    Anyone else have similar experience?
  • gwvinsongwvinson Member Posts: 27
    After 2000mi on my 1500 ext. LS 5.3L I have found a few problems. I discovered that while playing a song with heavy bass, the speaker in the third door really buzzed. Also my mouldings around the hood opening are coming loose. The window felt mouldings at the outside bottom of the side window are improperly installed. The right tailgate hinge seems like it is the wrong size, you can lift the right side of the tailgate up a half an inch. I don't think these are big. problems, I thought someone might want to hear about them. My highway mileage is about 18.5mpg.
    I installed a fold-a-cover which seemed to improve my mileage.
