    No he didnt come running. He was working in the basement and was using power tools so he never heard it.

    Im almost at 18K. I dont really know if mine needed the change fluid didnt look that bad but it was still a different color than what came outta the bottle. Glad i got the metal shavings outta there also.

    all in all it was a good experience

    AS A MATTER OF FACT YES... I could have missed it
    the two times I went through. I tend to read the manual before I ask people.
  • mledtjemledtje Member Posts: 1,123
    My 2000 Silverado has the AC come on whenever Recirc is selected - but I haven't found in the manual where it is supposed to do that. My 99 Silverado doesn't do that unless the outlets are directed towards the windshield (defrost).

    My manual says to select Recirc to prevent odors from coming into the cab, and when I do select Recirc I get cold about a mile down the road. Then it takes about another mile or two before I remember the stupid Recirc button turns on the AC.

    Tell where in my manual it says that is supposed to happen, and I'll highlight it so I can remember it.

    ive never had the air come on when i had the recirc on
  • 4x4man4x4man Member Posts: 222
    Mine does the same thing, it will stay on when the recirc is on, and A/C button is off. The A/C will only shut off when I press the fresh air button or what ever it is called. Also whenever I have left it on the fresh air button, but not have the fan on, no air comes in the cab through the vents, however if I left it on the recirc, then air will come through the vents with the fan off. Seems like they got it backwards on the 2001 2500HD's also, huh??!!

    The a/c comes on when the recirc button is pressed on '00 and later Silverados. It didn't do this on the '99s. I had a '99 and it didn't do this. I have a '00 now and it does it. My '01 Tahoe does this also. Apparently this is an "enhancement" from GM. I remember this topic being discussed about a year ago in one of these Silverado topics.

    LOL! Real men don't read owner's manuals! Just kidding. Ok I read it and now I see what it says. Still doesn't make any sense as to why GM did this but whatever. Thanks for the replies guys.

    Can anyone tell me where I can get a shop or service manual for my new Rado. The last I ever bought was published by Helm. It lookes like I am going to need one. Good evening to all.
  • txyank1txyank1 Member Posts: 1,010
    on the way in to work this am and I can't say for sure the compressor was on, but I can say the air was definitely a lot cooler than the 80 degrees outside at 6:00! I have also noticed that I have air blowing when EVERYTHING is turned off. Like flow-thru ventilation. I don't remember my '99 being this way and I don't like it. My '96 did this but I don't think it was all the time. I complained to Dealer who said "it was normal"!
  • ryanbabryanbab Member Posts: 7,240
    that is normal.

    Few tips turn the knob (one closest to the glovebox) to defrost not to the person (picture of person sitting with arrow) setting. Or close your vents. THis will stop the constant blowing
  • rayt2rayt2 Member Posts: 1,208
    you'll start to get condensation on outside from the A/C blowing thru (GM's enhancement engineering)if you have it set on full cold. However temp control knob can ajust for comfort level.

    PROBLEMS i really like the HVAC system
  • gator36gator36 Member Posts: 294
    I only asked the question about the A/C
    when it was doing something different than
    what I was accostomed to. For years I have
    Seen GM products behave differently.

    I love how cold it gets and have ZERO complaints
    about my new bowtie....
  • ryanbabryanbab Member Posts: 7,240
    Only ones i get is it gets to darn cold to fast but thats not a bad thing is it? Especially when temps are in the 90's
  • txyank1txyank1 Member Posts: 1,010
    Actually one of the first things I noticed was that the air never seemed to get as cold as my previous GM trucks. I knew, being an extended cab with more space it would take longer to cool the inside, but I think starting with my '99, that it takes longer for the air coming out to get cold and it doesn't get as cold.
  • 4x4man4x4man Member Posts: 222
    All strangeness set asside, I like my A/C as well it is very cold and cools off my truck quicker than my 97 Silverado did.
    The passengers that sit in the back seat enjoy the venting that comes through the center consol. Good thing for the rear venting as I would freeze before the people in the back would get cool.

    the temps have been breaking 100 in the shade for several days. My 2K 2500 extended cab can cool the temp to the point of having to turn down the blower within 5 minutes. Works for me.

  • txyank1txyank1 Member Posts: 1,010
    my '01 1500 x-cab could do better. Or at least do it a little quicker. It's not bad, but just not as good as my pre-'99 was.

    I have a 2001 C2500 H/D Crew Cab. After the first oil change we noticed a tapping and knocking noise during start up in the morning. We took it to the dealer and they wouldn't even look at it. Just said thats normal for this truck. Nothing is normal about knocking engine noises. I called GM and opened a case file with them. They asked me to take it to another dealer and let them troubleshoot. They kept it all day and told me I need to have a GM oil filter. Right. I called GM back and they said there is nothing they can do. Ok so I sent a letter to the state Attorney General and BBB. Someone from GM did call and offer me a 100,000 mile extended warranty at no cost. So I took it, they sent me the paper in the mail. I'm not satisfied because I really like the truck, but why can't they just fix the knocking? The service person where I bought the truck said that Chevrolet has had this problem since 99 and I did find where they had a problme with a wrist pin in the piston. Could it be they put a 99 engine in my 2001 truck? How would I know?
  • ryanbabryanbab Member Posts: 7,240
    One question is this knocking affecting your performance on your truck in any way?
  • layton86layton86 Member Posts: 2
    Just gas mileage but I know that is to be expected.
  • ryanbabryanbab Member Posts: 7,240
    how does this knock effect gas milage?

    How much so?
  • obyoneobyone Member Posts: 7,841
    affects gas mileage is to take a reading while it knocks AND again when someone gets it to stop. Does this make sense to you?

    To summarize....you can't find the mileage change until you stop the knock....which ain't gonna happen in this case.
  • ryanbabryanbab Member Posts: 7,240
    thats what i am getting at

    No performance losses, nothing negative happening except for an engine noise.

    I see a few trucks everyday at work with around a(or over) 65K miles (99 and 00 silverados). They ae running fine. I even see a silverado with 90K (00 model) and it has this engine tick (knock). hasnt slowed it one bit.

    Make sure the non-GM filter that was installed has a check valve in it to help keep oil in the right places overnight. The easy test would be to put on a GM filter (available at wal-mart and others) and see if the start up knock goes away. Just a thought...

    Jim
  • ryanbabryanbab Member Posts: 7,240
    AC delco PF 59 (gm filter) along with mobil 1 wont help the problem
  • rayt2rayt2 Member Posts: 1,208
    Tolerances whether enough or excessive. My 5.3L has the initial tap for first few seconds then it goes away, if it gets worse I'll press my case with GM if not I just continue changing the oil when needed and cross my fingers since I have owned and applied the lemon law to a past GM product.
    Of course maybe my noise is a result of the "afetrmarket" bug deflector I installed, at least that's what they stated on service ticket when I complained of wind noise from 3rd door at highway speeds, "unable to verify customer complaint" how many have seen that response on their service tickets??

  • ryanbabryanbab Member Posts: 7,240
    I feel for ya. I wont let them write down could not duplicate unless i am there and cannot hear or see the problem.

    They almost did when my rear brake was squeaking %^$#%^@&* tech, the foreman was by the exit and heard the squeak and brought it back in the shop himself.

    I am waiting for them to tell me the brake noise in the rear was because of my grill guard. I need a good laugh

  • rayt2rayt2 Member Posts: 1,208
    Yea I was so pissed, they took it out for a 2 mile ride to verify my complaint in town, never got it up past 40 mph. They also made sure they documented that I had a cap and ventvisor's also, love how they try to cover their butts for inempt work. Well when I got the customer satisfaction survey form I let'em have it on that, don't ya know I got a call two weeks after, saying they were concerned about my complaint & I should take it back referencing a # they gave me. When I get time but for now the hell with em.

    I'm off to Canada tomorrow with the trailer so we'll see how Big Blue runs on this trip. Last camping trip I got 12mpg towing.

    All in all I've been pretty happy with this truck, should have gotten the 8'bed though.

    If you remember. About 2 weeks ago I posted re: a clunk sound I was hearing from what I thought was the front coil spring when reversing out of my driveway or making turns over rough areas at slow speed.
    Took my car in to the dealer. The tech said he used chassis ears and that noise was coming from the leaf springs. he wants to replace both leaf springs and shackles.
    What do you think?? ANyone....
  • ryanbabryanbab Member Posts: 7,240
    go for it. New leafs cant beat that

  • obyoneobyone Member Posts: 7,841
    I'm sure anyone could tell the difference between the front and rear where clunks are concerned. Are you sure the tech used the chassis ears in the right places? Sounds more like he had it up his.......

    A spring clunk is most obvious. So much so that you don't need no chassis ears to know it's the rear springs. Then again, it may be a good idea to let them change the springs and shackels. And when the clunk persists you can ask the tech, "Now what?"

    "After the first oil change we noticed a tapping and knocking noise during start up in the morning." If Layton was not having a problem until after his oil change and the filter was replaced with a non-gm filter, I stand by my statement to check the filter for a check valve. If you have an engine designed to use such a filter, the use of a non-valved filter can cause a tap/knock for the first few seconds after startup. This is not to be confused with the light knock some of the engines have when idling.

    Jim
  • obyoneobyone Member Posts: 7,841
    position. Not sure how much of a difference a check valve would make? Hmmm...does this make any sense?
  • 4x4man4x4man Member Posts: 222
    My truck also taps for the first few seconds after startup, WITH a GM oil filter. What difference does it make when the filter is mounted upright. How will a check valve in this situation make any difference?? The oil filter will be full of oil while the engine is running (obviously) and then when the engine is shut off the filter is still full of oil and will not be able to drain out of the filter..

    Still have my fingers crossed that switching to synthetic oil will quiet my engines piston dance.....

  • mledtjemledtje Member Posts: 1,123
    In the case of the Silverado where the oil filter sits upright -

    The check valve does not so much retain oil in the filter as it retains oil in the rest of the engine.

    When I pulled the oil filter off my truck (4 days ago) about 1 cup (or more) of oil came out of the block before I could get the filter off. Happens everytime and tends to make a big mess.

    I love hot oil running down my arm!!!!!

    It will takes a few seconds for the oil pump to replace that oil (in the passages in the block) before the oil pressure can come up to normal. It would make sense that the engine could make some noises before the oil pressure comes up.

  • ryanbabryanbab Member Posts: 7,240
    Tip for ya let your engine cool down a little bit before you do the oil change
  • 4x4man4x4man Member Posts: 222
    Don't mean to get things going, but hey they are fighting about "torque theories" on the Silverado topic, so I guess we can be different.. :-)

    My only other question would be is it the check valve holding the oil in the rest of the engine as you say or is it because the oil is sort of "backed up" because it cannot drain past the oil in the oil filter and it is just sitting there in the block above the filter??

    I agree on the hot oil down the arm, I now use a zip lock baggie around the filter when I take 'em off...ok call me a wimp, but I don't complain about hot oil dripping down my arm anymore... :-0

    QUIZ TIME.

    There is a reason us experienced vehicle owners change oil while it's hot. You have 12 hours to answer or your truck will self destruct!!! j/k!!
  • ryanbabryanbab Member Posts: 7,240
    I dont let it sit for hours but if you let it sit for 10-15 min it makes a difference.

    Its warm but not scalding hot

    All the oil drains out also. After i take out the drain plug and filter i let it fully drain.

    Ryan
  • ryanbabryanbab Member Posts: 7,240
    oh yea when its hot it flows out much easier
  • modvptnlmodvptnl Member Posts: 1,352
    You get to keep your truck........for now!!!
  • obyoneobyone Member Posts: 7,841
    '91 300ZX
    '91 Acura Legend
    '93 Lincoln MkVIII
    '95 Lincoln MkVIII
    '97.5 Regal GS
    '00 Denali
    '00 rado

    The only vehicle out of the list that makes any noise on startup or otherwise is the rado. Now please explain why the oil filter should make any difference. No knock, no ping no nothing out of the Nissan, Acura, Lincoln, Regal, or Denali....only the rado. AND I used fram in the Lincolns.

    Actually the secret may lie in using 75w-90 in the motor as everything will surely quiet down....do they still sell that gunk called STP?
  • mledtjemledtje Member Posts: 1,123
    I currently own:

    87 VW Vanagon
    91 Mercury Capri (Mazda engine)
    99 Silverado 1500
    00 Silverado 2500
    67 BMW 600 MC
    70 Triumph Bonneville MC
    76 BMW R90S MC
    78 BMW R100RS MC

    The VW is sometime noisy when started. That means it is time to add or change the oil.

    The Triumph is always noisy. The rest are quiet. The Corvair I used to have would sometimes have a lifter collapse while sitting and it would take 3-4 minutes to pump up and be quiet.

    5W-30 in the trucks, 10W-30 in the VW and Capri, 20W-50 in the motorcycles.

    All the above means I don't know why a filter should make a difference - unless it is the oil draining out of the block. Since I've haven't heard the noise from my Silverado's I don't really know.

    GM didn't want Ford to have all the glory with their piston slap, so they invented one of their own.
  • toortoor Member Posts: 38
    Well, just got my truck back from the dealer. I took it in for a clunking sound from the FRONT coil spring.
    They put new LEAFS in. Clunk was still there. Hmmmm. I wonder why?!
    So I printed out the TSB that obyone posted about the front coil spring insulator and took it down.
    They changed the insulator, and WHA-LA! clunk gone. Well, I guess I got new leafs out of it.
    How can you mistake a clunk coming from the front spring for bad leaf springs????
