GMC Yukon XL and Yukon XL Denali

    I got the parts from RadioShack, web site""

    6 Amps rectifier Diode. Pkg of 4 $ 2.29
    Part # 276-1653

    Relay 30Amps 12V $ 5.99
    Part # 275-226.

    Remember to put the Diodes correctly, you need to cut both low beams yellow wires close to the headlamp and put the diode in line with the cutted wire making sure of the direction of the diode.
    By the way, thoses diodes are exactly the SAME than the 2 in the KC box.
    Don't you think that the KC fake relay/electronic module is a rip-off?
    Diodes are designed to let go through only the negatif on one side and the positif on the other side.
    In another word you want the negatif from the truck electrical,(thoses lights are negatif switched)to be able to go through the diode when you are in low beam.

    I have been monitoring a 1-2 drip per day oil leak under my 2001, ¾ T, Sub w/ 8.1 L for the past few days. I got bold today and shimmied under the running boards to see if I could spot the source. I saw a drop formed on the bottom of the oil filter. I grabbed the filter and it was loose. I was able to rotate it ¼ to ½ turn before it snugged up. I thought I had solved the problem. I took it for a spin and parked over a clean paper bag. Within an hour a drop had hit the bag and another had formed on the bottom of the filter.

    When I attempted to tighten the filter, I did so from an awkward position and was not able to put much torque on it. I suppose that if I positioned myself better, I could tighten it some more by hand. How tight should a filter be? Can I over-tighten it by hand? Apparently the mechanic at the dealer who changes my oil/filter does not think it has to be very tight at all. All comments are welcomed.

    Looking into purchasing a Sub. Saw back in Feb a lot of talk about the cold air problem on the passenger side. Has there been a fix? Also is there any other major problems that are occurring with the Sub. It seems in general that everyone is pretty happy.

    Just bought a loaded XL,1500,(6/01) with every option. MSRP 44,500. Details>.. dealer took 6500 off plus my 4100 GM Card , and 1,000 college grad, and 1.9% on the balance. Yes I feel good about the deal. (Salinas, Calif).

    1. Steering wheel is not on straight, even after going to the dealer for repair. So has to go back again.
    2. Hood not on straight, (almost rubbing on one side). Dealer tried to fix but only put 8" crease in the side of the hood.. now needs official body work. So has to go back again.
    3. Cut on the interior plastic driver door panel. Dealer got replacement part, but the new one came with a cut on it, so has to go back again.
    4. Could not figure out how to get the middle headrest off. The dealer (sales&service) and manual does not state. Finally the car wash guy at the dealer used a paper clip, and with the paper clip, showed us how to take the headrest off.
    5. HOME LINK DOES NOT WORK. I have a newer Genie electric garage door opener that I bought at HOME DEPOT, and the rotating codes do not work the the HOME LINK system. The manual says to bring it into the dealership, but they say it won't work. Any suggestions?????????

    Fit and finish seems only , Yukon AL was made in Mexico. Am I just to picky? Or is this the way these trucks are?

    It rides great, feels solid.

    Guess I will be buying extended warranty.

    In order to get the Homelink to work with the rolling the manual again. I don't have it with me but if you go here:

    it should answer your question.

    Good Luck.

    No your not to picky, but I don't think you have a lemon. What you have is a incompetent Dealer & Service dept. Sounds like their a bunch of idiots!

    Just for kicks sent E-mail to Nokia requesting a method to connect a 8260 to an external antenna. Quick answer came back - we don't have a way to do that.
    Went to
    They show a picture for a external antenna but for use with a 8210/8290 cell phone only.
    Would it be practical to trade out your new cell for one of the above models? Go back to your Cell Shop and compare the cells. Some may have an external antenna jack.
    Before doing this I would investigate the new very short cell antennas by Antenna Specialist. Like they are using as a roof mount on the new Chev. trucks.
    The antenna they pictured would likely do a good job but it is long and you may not have clearance in your garage. Just a few thoughts on your conversion.
    Last item - if you are not using the OnStar radio that antenna could probably be made to work IF the cell has an external coaxial jack on it. I don`t. think yours does.
    Hope this is not as clear as mud.

    Tighten it about 3/4 to 1 turn after the gasket seats. If it leaks, tighten it a bit more. Overtightening it just makes it hard to remove - I doubt you can strip it out by hand unless you are a lot stronger than I am.

    I had a similar oil leak on a 8.1 liter. The main difference was that it leaked signifcantly more but it came from right near the oil filter. It was not the oil filter however. It turned out to be the oil cooler line that had faulty weld and it turned into a mojo leak where I had the vehicle towed back to be fixed. I would make sure that the leak is coming from the filter and not some where else.

    Why monkey with building a headlight relay for a "quad" system. Visit the R & D site and purchase one as so many others have recommended. The one they sent me arrived in a few days and installed quickly on my 2001 Tahoe with very detailed instructions. Much simpler than building my own with relays, wire and a fuse holder like I did on my 99 Tahoe.

    Check out Criterion Cellular. They sell external antennas, as well as antenna adapter kits that plug directly to your cellphone without requiring a booster or special kit. I've been meaning to do this for my own phone, but have been procrastinating ;-p. If you can't find what you need, try phoning them

    Let us know how it goes!

    Since I havn't see the R&D,I can't have an opinion on it.
    The only thing that I know,beside the fact that the KC module is a piece of crap,is that ANY relay/module that use the very small wires(18 gauge)going to the headlamps as a power source to supply voltage to the low beams when the high beams are on, is a BAD design.
    Electrical wires are sized depending on the load,(Amperes) that they are designed to carry.
    You calculate Amps by dividing the wattage,( let say 45 watts per low beam bulb)by the voltage(12V)
    in the case of the truck.
    So each low beam bulb draw about 3.75 Amps.
    In this case you are aking a wire that was designed,(sized) to carry the Amperage for 1 bulb,to carry the Amperage for 3.
    What happen in this case?
    It's like trying to put 1/2 inch bolt into a 1/4 inch nut,it is not going to go through.
    Resistance is created and the wire get hot.
    Where do the power source on the R&D come from?
    Did you try the simple test of pulling the flash to pass lever when you are on low beams?
    Are you low beams as bright when you are in high beams than with the flash to pass?

    I recently sold a 92 Burb to CarMax and was interested in buying another one. I wanted to know if I could still qualify for the $1000 owner loyalty rebate and , if so, what type of documentation is need to receive it? I understand it expires soon (June 30th?). I'm planning to buy one this weekend. Thanks for a quick response.

    looking to do a deal on a white Z71 Subn.. found the one I'm looking for but it has 4.10 rear... my wife has a new Black '01 Subn 4x4LT w/ 3.73 rear...

    does anyone have any info on what the difference in gas mileage would be or if any other problems with the 4.10 gears.. don't need to tow anything large so don't really need the 4.10

    got to do the deal by this Sat to use my $1k loyalty rebate again( also used it on my wife's) as that's the last day.. also have to take advantage of Lease Incentive Program.. old lease on my '99 Subn gets wiped penalties.. plus all payments remaining (8) are gone..

    I called Chevy Incentives # at 1-800-950-2438.. all they said on a couple of different phone calls.. that there would most likely be new loyalty rebates.. but not yet in writing .. whatever that means.. so 6/30 remains as last day...

    anyone hear about any other Incentives coming up..???

    I am planning to buy a new 01 Burb 1500 2WD LT from Marchant Chev. in Ravenal SC this weekend. They've offered it at $98 over invoice less $1000 dealer cash and $1000 owners loyalty rebate (if I qualify) bringing the grand total to $34,031.69 including sales tax, tag, etc. (MSRP of $40,603). This sounds like a pretty good deal. I'm looking for some feedback fron other recent purchasers as to how this all-in price stacks up. P.S. I'd prefer to purchase it in the Atlanta- Metro area but the dealerships don't seem to be as competitive. Any thoughts?
  • stakeoutstakeout Posts: 173
    I used my $1K Loyalty coupon recently on my wife's ne '01 Subn.. can be used again ..

    no coupon is needed according to Chevy but you then have to show a registration or some type of current ownership of a Subn or Tahoe to get it.. here's what the coupon looks like.. ... also at message # 692 my post..

    good luck

    Just received an email from GM on Yukons. . . . FYI
    An additional $1,000 on top of any other incentives already offered - 7/1/01-9/30/01.
    **Note an exclusive offer code did appear on my email**
    Says to print it & contact local GM dealer for details.
    That is on top the $1,000 loyalty refund.
    A deal. Wish I could have got that 4 months ago.
    That makes me want to sell my 01 YDXL with only 1900 miles. Just to see if it works and purchase a 2002.
  • This may be too good to be true? I have a Yukon XL being held for me in Kennesaw, GA. My 99 was totalled and I've been told by the dealership that Loyalty money of $1,000 goes away on 7/2/01.
    We're leaving today for family reunion and have arranged to purchase over the phone but need to know if this is true! How do I get the code for the extra 1,000?
  • stakeoutstakeout Posts: 173
    the $1K Loyalty Coupon is good right now for BOTH GMC and Chevy Subn, Tahoes, GMC Yukon, Yukon XL .. it ends JUNE 30th Sat... you DON"T need this coupon per se only have to show proof like a registration that you own a Subn, Tahoe, YK, YKXL

     there is anotherDEALER CASH INCENTIVE of $1K that some dealers are passing along to their customers.. that's the one that ends JULY 2 go to this link on Edmunds at and put in your state..then follow instructions.. or go to for the Southeast Region

    I really appreciate this forum. Helps when discussing issues with the dealer.

    I have a 01 Burb. So far love it. No major issues. Do have a few questions for the group:

    1 - squeaky metal noise on driver door when opening/closing - not hinge related, but something inside with the door stop? Any guesses on how to check without taking to dealer?

    2 - Saw earlier post on air flow noises on front door seals. I have the same, more so on driver's door. Is this something we just live with? No seals appear to be worn or torn.

    3 - Rear suspension - slightly lower on left rear (about 1-2". Is this an issue of when the vehicle's suspension was compressed during transport from the factory? Is it easily fixed?

    Thanks for the input.

    Oh, I just subscribed to the ONSTAR Personal Communication Service (cell phone) They offer 30min free trial. I thought maybe with all the hands free legislation coming down I would check out the systems capabilities before going out an purchasing more gadgets.

    It would be great to hear from anyone who has already tried it.

    Looking for a litte advise from the group. I am looking at a 97 K1500 4x4 LT with 56,000 miles.
    The truck is in near mint condition has quite a few options. The original Sticker price was $37,117. I left with a price of 18,450, but think they will sell for $18,000. even. Did a carfax check against the VIN no problems found.
    Is this a fair price? I live in NY but the truck was from PA, no salt state. Please advise soon as I have an appointmet to deal Saturday.
    Thanks in advance

    I'm no engineer but I was under the impression that headlight relays, like the one I have installed from R&D, simply "turn on" the relays for both the low and high beams at the same time. I don't think it is trying to supply the amperage directly to the bulbs but simply send a low voltage to both the high beam relay and the low beam relay. With my R&D setup there is no difference between the flash to pass and having on quad high beam.
  • lucnoellucnoel Posts: 31
    If you truck have blue smoke coming out of the exhaust when you start it in the morning, that mean that the valves guide seals are bad.
    I agree that 1qt per 1000 miles is not normal but manufacturers said that to protect themselves.
    In any case since you use more than that,1qt per 600 miles,GMC should fix the problem for free.

    It will seems that R&D is a much BETTER design than KC.
  • rhanson3rhanson3 Posts: 69
    I have the KC relay, the light is not good. Where can I purchase the R&D relay. Installation?

    turned in my 'old' '99 'bourbon using the GMAC Lease incentive.. no penalties/all remaining payments waived...

    was looking for a loaded WHITE Z71 for the past three/four weeks in the NC-SC and surrounding areas. .. after many calls around.. I found it myself.. so much for dealer locators.. they stink... my local dealer who I just leased a Blk Bourbon on 4/30 couldn't( or wouldn't ) find me one.. I'd rather deal locally with them but they just couldn't 'produce'..

    located one at MarchantChevy in Ravenel, SC ( 12 miles south of Charleston).. had been there beforein the past but this time he had it .. only option not there was a moonroof.. oh well :( didn't matter to me... jumped on it.. got the right price at $98 over invoice minus the $1000 Subn owner's Loyalty .. also minus the $1000 Dealer's Cash Incentive...

    the only minor bad point.. the lease manager typed in a Lease percent factor of 8.75%.. I know it was 7.75%.. he got a little perturbed when I told him to keep the truck if he didn't change it.. he did... was it an honest mistake???.. I think not.. but knowing how to figure a lease ( from Edmunds site) I handed him my figures on paper.. not nice... darn dealers always have to leave that one little bit of bad taste in your mouth... gotta watch them all the time..

    here's some links to pics of my White Z71 and my wife's Black '01 LT 4wd 'bourbons$09.jpg$05.jpg

    R&D can be found at the following address

    It comes with very precise instructions and simply "crimps" into the existing wiring. Really no need for tools except maybe some pliers.

    What are the changes going to be for the 2002 model year...have not been on the board as our 2000 (after several trips to the dealer with help from the board) has rolled up a trouble free year. Am thinking about ordering an 02 and wonder what will the changes be??? Thanks!
  • adplusoneadplusone Posts: 66
    Wondered thru a large lot of 2001 Burbs this weekend and was amazed at how the trim (black or body colored) on the LTs varied.....flares, body side moldings, bumper caps there any reason to the madness??
