    just leave it in drive... my opinion anyway. I've heard rumors and reports that it saves transmissions to have it 3rd while in town, but I haven't found definitive proof. I have never had a problem leaving any vehicle I own in D, including my 04 Impala. It's quiet enough and smooth enough that I never feel the gear changes, but in my S-10, also with a 4 speed auto, while in town and at low speed (below 35 MPH), if I drop it from D to 3rd, it doesn't shift down because it is already still in 3rd. It's not till above 35 MPH that it shifts to D...

    Just trying to think ahead as summer is coming and so is the heat, but I also want to keep up on prevenative maintenance. 04 Imp, with the 3.4 motor. 34K miles. It's only been a few thousand miles, but it has also been 3 years (build date was early-mid 04, can't remember exactly when, but it's coming up close to it's 4 year build date anniversary). Would it be wise and prudent to change to coolant out, or am I just being overly cautious?

    I was just told of the recall or settlement for the intake manifold of the Chevy Impala. We just had ours replaces for about $700 or so. The gasket was leaking, somehow causing the heater to not work. I couldn't get any heat to defrost my windows on those cold spring mornings. We also had a ignition sensor replaced just a month before the intake manifold. And yes, my steering wheel makes a lot of clicking noises when turning. Thanks for the info.

    the intake settlement is a done deal, they extended the warranty a few years but it is long past.

    the clunking is an easy fix, look under the dashboard for the ISS (intermediate steering shaft., they had a problem with them binding up because of the loss of lubracation. Take some wd-40 or any type of lube oil, you will see a rubber boot. inside that boot is a mini u-joint that slides on a splined shaft. peel back the boot and spay some stuff in there, your clunk is gone. You can also try putting some grease in there instead. I have to spray ours about once a year, a 5 minute job. Don't let the dealer try to sell you an ISS

    A product called "PBBlaster" seemed to work pretty well for this too.

    Another thing I discovered towards the end of my Impala's time with me; if you wipe down the weather strip around the doors with silicon spray (spray it on a rag, then rub on the rubber to avoid over-spray) it REALLY quietened the ride. As the rubber dries out it starts to squeak, but applying silicon made mine sound as quiet as new (well, except for the occasional ISS clunking).

    (Oh, and if anybody cares, I DID finally find my pin set that I got for taking part in the 2001 Impala brochure...they were in the one stack of boxes in the garage that I didn't go through last time. Also found a couple of other items I cherished as much, that I'd accused my wife of throwing away, so had to eat a little crow on that one.)

    :confuse: hi all, i have noticed sort of a low pitch noise in the cabin while breaking or just driving without pressing the gas pedal. weird thing is that there is no noise when breaking and I 1) press gas pedal, 2) press and keep holding power windows buttons or 3) turn on rear window defrost. Anybody had this or any ideas what that might be? bought this used wiht 60,000+miles just few days ago and there was nothing .. would appreciate any help. thanks.

    I have noticed a coolant leak in my 2004 3.4l Impala. The car has 37,000 miles on it.

    I first noticed a couple days ago after I walked up to it after it had been parked awhile. How long it had been parked I don't recall. But I noticed a wet spot in front of the pass. front wheel. I also smelled that tell tale sign of coolant. I dip my fingers in the couple of spots and could tell it was coolant. A little concerned I popped the hood and checked the coolant level. It was a little low, but not too bad. I also hunted for where the drops could have come from. I couldn't really tell, but I could tell that at the bottom corner of the radiator, some coolant had leaked recently. I didn't worry about it much to be honest however and just told myself I would keep an eye on it.

    Well tonight was a good night to keep an eye on it. I walked into the garage and noticed a good sized puddle on the floor. Sure enough it was coolant. The car had been driven twice that day. First into town, a distance of about 20 miles round trip. The second trip was to the bank, a distance of about 3-4 miles round trip. It was after the bank trip that the car decided to leak. The previous trip didn't produce any leaks. I also didn't notice the when the leak happened because I didn't drive the 2nd time and it was this evening when I had noticed the leak, several hours after the car had been parked.

    So I popped the hood again and this time I spotted where I think the leak is coming from. I am posting pictures to hopefully clarify this. It appears to be at the top of the radiator at the mount right next to the cap. It appears to have been a semi-force-able spewage as there is evidence on the hood liner and the radiator hose. Again refer to the pictures. I started the car to see if I could duplicate this while I watched. Parked the car did nothing. So I took it for a spin around the block to warm it up.

    While driving I paid close attention to the temp gauge. It seemed to warm up much quicker than I seem to remember. That however could be attributed to the fairly warm night (about 70 F) and the fact that it had been driven just that afternoon on a warm day. The other times I paid attention to the warm up times were in the dead of winter when I watched the gauge to know when I could turn the heater on. As I drove, I noticed the gauge fluctuate. The first was when it got to the half-way mark, then it dropped just above a quarter and then rose again. Then it would rise, but not quite to the halfway mark and then fall a little. It did this during the entire time I drove. It never got above halfway, but it never stayed steady. I have never noticed this type of variation before. It may be because I don't pay attention to the gauge as I should, but I would think that if the temp gauge varied that much I would notice it?? I also do not drive the car much as it is my wife's daily drive and she wouldn't know what to look for. I was varying my speed from a residential speed of 25-30 MPH to a highway speed of 60 MPH, but the temp didn't seem to follow a pattern based on my speed.

    After I got home, I again popped the hood to look for any evidence it had leaked while driving. I could find no fresh evidence. I let the car run for a couple more minutes and then shut it off to see if the cooling down cycle would produce anything. It didn't. It still hasn't as of this post...

    So I am open to suggestions as to what it might be. Any thoughts?

    Pictures to help visualize the problem...

  • Nice photos.
    It is unusual to have a coolant leak with only 37k on the vehicle.
    I suspect that you have a small leak in the radiator hose wich is leaking onto the serpentine belt and then getting sprayed onto the underside of the hood.
    You need to look closely at the hoses while it is running and see if one of the hoses is leaking. (Keep your hands clear of the pulleys, belts and fan!)

    Also, the picture that identifies the waterpump is correct. ;)

    Even if the coolant hasn't been changed?? It has been 4 years, although it is DexCool which I have never liked, but it is supposed to last 5 years or 150K ???
  • I've been detecting a musty or dusty odor when I turn the AC off and the fan on, so I bought a new cabin air filter for my 2000 Impala. But for the life of me I can't find where it installs. I've looked behind the glove box, under the dash on both sides and even inside the engine compartment, but I can't find one. I was visiting another site that said on some models there is none. How can I determine whether mine even has one on my car, and if so, where it is located? :confuse:

    My 2001 did not have but I put one in. Do a search for impala hq. In the how to section it tell you how to change it.
  • nosirrahgnosirrahg Posts: 870
    You get to it from under the hood, on the passenger side; it's not really that complicated to do, but hard to explain...but the info on impalahq if I remember correctly give you step-by-step instructions that should be easy to follow. Even if your car didn't come with a filter, one can be installed (my 2000 didn't have one originally, but I put one in).
  • I believe the "Cabin" air filter was only offered as an option on the Impala LS models.
    My 2002 Impala does not have a "Cabin" air filter.
    I am not sure how difficult it is to retrofit the cabin air filter into the non-equipted Impalas.

  • The following link from the Wix Filter website indicates how to replace the cabin air filter. Click on the web link and go to section 7 of the brochure:

    That's pretty much the process; it doesn't seem intuitive to be going at things from under the hood, but once you figure it out it's really easy. And even if you have a base model, all the duct work and such is there so all you have to do is buy the filter and slip it in.
  • I took care of it during lunch yesterday. It only took me about 10 minutes from start to finish. I appreciate all the help. Thanks.
  • I am having the same problem, the antifreeze is coming from the radiator cap and I would guess that is where yours is coming from also. I have replaced the thermostat and the radiator cap but it is still coming from the vent holes on the cap. I do not see it but I have traced the leakage to the cap and I have antifreeze in the same areas that you have. I have noticed that the cooling fans don't run when the ignition is shut off, I thought they were on a thermostat and would run after the car was shut off if needed. I think it over flows after it is shut off as I have the antifreeze on the driveway. Does anyone have any answers to our problem or is there something else that I need to report to help solve this issue.

    Not sure -- I have been keeping a pretty diligent eye on it and I haven't seen a repeat of what I was seeing a few weeks ago. A couple of time it leaked quite a bit, then a not so much and now I am not seeing anything. Coolant levels are still full. So not sure what it is and so for now I am just watching it real close.
  • The front left Hub Bearing on my 2000 Impala LS(3.8L), 91,280k mi., was bad, when the car was lifted you could shake the crap out of the wheel. Got it replaced and the car runs smooth. HOWEVER, now TRAC(Traction) turns off as soon as the car is turned on, the ABS light comes on and System Message: Service Traction System. I can't turn on Traction at all. If the light isn't there as soon the car is turned on, the light turns on as SOON as the car starts to move about an inch. The left Hub bearing just got replaced. It can't be a faulty part from the factory... I'm hoping. And SOMETIMES it's intermittent. I can't shoot the hub bearing itself(continuity[ohms]), it just shoots open(overload, infinite resistance) and I shot the wires back to the Electronic Brake control Module. The wires for the front left and right splice as one assembly back and the rear left and right HUBs splice as one assembly as well. The rear wires shoot good and the front ones shoot good. HAYNES manual has the schematics but they're pretty vague. So I'm asking for some other means of troubleshooting this problem. I'm not taking it to the dealer so they can make me bend over to pay an arm and a leg for this. SOMEONE HELP. FYI, before the Front, Left Hub bearing got replaced, I had the ABS light. SOMEONE HELP, losing my hair over this!!!
