Honda Accord (2003-2007) Maintenance and Repair



  • temj12temj12 Posts: 450
    How in the hell do tires wear out in 24k. My 2005 Accord EX-L original equipment tires lasted to 75,000 and could have gone 90,000. I just chose to change them out. I rotate my tires every 10,000.

    I have leather seats and the driver seat is very uncomfortable for my back. I wonder if it is the lumbar. I try it with it activated and not activated. Does anyone else find the seat uncomfortable? It really wears on you if you are taking a trip.
  • I have a 04 EX-L sedan and find the seats to be more comfortable than any other car I've owned. I made a 3000 mile trip and felt great.

    My girlfriend also made the trip with me, and for her, She was a little sore at the end of each day. She had to use a small travel pillow for relief. I guess it's a personal issue with each person. Some find the seats great, some as you have found do have issues.

    Have you tried a small lumbar support pillow, the type designed for vehicles? A trucker friend said he picked one up at a truck stop, and it made a world of difference for him.

    The higher the speed rating, the shorter the tread life. Also, as I stated, front tires will wear more quickly, so a pair of front tires will need replacing sooner if not rotated (I don't rotate).

    Need to know if this is a major issue ... while sitting idle in my garage, I noticed when I put our 2007 EXL V6 Accord (~54K miles) in reverse, there was a high pitch hissing sound. Also heard the sound when putting the gear in drive. Is this a transmission related issue, possibly with the clutch? Can anyone shed some light on this? I've heard that if there is any problem with Honda's transmission, they don't repair it, they replace it. If this is not related to the transmission, what actually would need to be repaired?
  • I would like to replace the spark plugs on my 2003 Accord LX - I4. The mileage has been dropping down to 23 mpg which was 25 on the last tank of mainly city driving. I have 80000 miles on it now. I purchased the recommended NGK irridium plugs. I was about to install, but I could not find in the owner's maual any info. about the gap required. Might anyone have gap requirements? I would greatly appreciate it. Happy Hondaring.

    The NGK and Denso plugs should be gaped correctly right out of the box. No adjustment should be needed. It's a good idea to check it though, just to make sure it's in the range.

    Aren't spark plugs good for 110k? I'm wondering if I should do mine, but I know that they're supposedly good for a lot longer. I'm at 71k.
  • tankbeanstankbeans Posts: 585
    IIRC the gap measurements are also listed under the hood. At least they were on my 95. I haven't tried anything with the ones in my 03 since, supposedly, they're good for 110k and I'm not sure if the fact that it's a DOHC will make it more difficult to take care of.
  • elroy5elroy5 Posts: 3,741
    A lot of Honda experts have mentioned that the spark plugs CAN last 105k miles, but in some cases the plugs are worn enough before that point, to make an early change worth while. If your gas mileage has slipped a few mpg, new spark plugs could help. I am trying to wait until at least 80k miles to change them, but don't know if I can hold out that long. Depends on what mileage I get from the next few tanks of gas. Changing the plugs on the 4 cylinder should be easy as pie. The rear bank of cylinders, on the V6, are a challenge though.(long reach, and tight quarters). I'm not looking forward to setting the valves on the rear bank either.

    I'd bet that whoever was more sore at the end of the day was the one who did less driving - only the driver's seat has the lumbar support (as far as I know - I'm never a passenger in my car) - I believe the passenger seats do not.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Personally, I'd peek at them before that. Spark plugs can sometimes give you good hints as to engine condition or overall efficiency.

    My car would not start the other day when it was about 0 degrees out. I was surprised as it is less than 3 years old. I think lots of short trips in real cold weather does not help as the battery does not get much time to charge after a stressful start.

    Anyway, I decided to go old school and add some distilled water to the battery. It is the OEM maintenance free battery, but the covers do come off so you can add fluid. Since the water was added the battery has newfound vigor and where it used to crank slowly to start the car it now fires right up just like new - even in temps near zero. Going down to about -15 in a couple of days so that will be the real test.

    Cost for New battery was about $80. cost for a gallon of distilled water was $.82 (only used about 8 oz).

    Just thought I would share for anybody with a weak battery.
  • How exactly do you remove the cover of a maintenance-free battery -- pry it off with a screwdriver, or what? And then, how much water did you add?

    Sounds like a very useful tip, really, one I could make use of myself, if only I had the confidence to know what I'd be doing. Never heard of refilling a maintenance free battery before, but if it works, hey, more power to the user.
  • For the past year I've been intermittently "locked" in my car. There is no special time when this occurs - it's been in cold weather and warm weather - after I've been driving for a while or after a quick trip.
    When I press the unlock button, the door lock pops up and down very quickly - there is not enough time to open the door. I have been "locked" in my car for as little as a few minutes to as long as 1 hour. I am able to manually pull up the passerger left side lock and crawl out the back. I called my local Honda dealership who said they are unaware of the problem and unless they can re-create it - it can't be fixed. Can anyone help me here? Today it happened when I was going for gas - locked in the car and it was 19 degrees!

    .....spark plugs CAN last 105k miles, but in some cases the plugs are worn enough before that point, to make an early change worth while. If your gas mileage has slipped a few mpg, new spark plugs could help.

    At 75k, recent MPG calc's are showing a slight decrease. I thought it was the winter blend fuel.

    I'm vacillating between a new Acura 6M and budgeting for the labor intensive big
    time 105,000 mile service for my Accord 6M coupe.

    Would it be a fair statement that this service (timing belt/water pump et al, plugs, valve adjust could run me $1000 - 1200 at the friendly Honda dealer's sprinkled around our state capital?

    season's best, ez....
  • dudleyrdudleyr Posts: 3,469
    On my battery there are two rectangular "caps" that occupy the middle third of the battery. Pry them up with a screwdriver. This will expose the 6 openings into the battery. Fill each opening until water gets to the plastic sides of the openings (about an inch or so from the top of the battery). Replace the two caps and you are done.

    Love cheap fixes. When the alternator went out on my Integra at 130k miles I just replaced the brushes for $6 - still going strong at 240k.

    Most repair places want to replace the whole part these days. More profit in an expensive repair - and probably less chance of return with a whole new part.
  • I will definitely give it a try. Sounds so simple to do, even the mechanically-challenged (like me) couldn't mess up.

    Winters are a problem, no doubt, with these newer cars and their smallish batteries. I make it a point to take a long run (30 or so miles cruising at 60 or better) at least once a week, weather permitting. And -- I think -- it's a good idea to at least start up the car and let it idle for about 20 minutes each day, rather than let it sit two or three nights in a row in freezing temps. The idling probably does little in the way of recharging, but it just might slow down the battery-drain that would occur otherwise.

    Forgive me for sounding like an idiot, but how difficult is it to get at the plugs? In my 95 I could see them from the front and thus could reach in and pop them out, but with this one I know it's DOHC and a little different. I'm trying to learn to do general things myself so I can save some money in the long run.

    Thank you for your help. This website has proven very helpful over the couple of years that I've been using it.

    Also, I have been noticing that I'm getting lower mileage than I was at this point last year and wonder if it might be time for new plugs and stuff. Last year around this time, under similar driving conditions and distances (I've since changed jobs and don't have an identical drive) I was getting 23-25 during the winter. The last few tanks I've gotten 19-21. NOT very good in my opinion.

    FWIW I'm now just over 71k and would like to know if there are any small things that I can do in order to perhaps increase mileage a little. I live in MN so defrost is virtually a must for most days. Any tips or ideas. Thanks.

    Which engine do you have? You have a 2003 LX right? 4 or 6 cylinder?
  • thegraduatethegraduate Posts: 9,731
    He has he 2.4L 4-cyl I think...
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Oh okay, he has the coil over spark plug system. So he has to remove the coils first to get at the plugs.
  • tankbeanstankbeans Posts: 585
    You would be correct.

    Mr. Shiftright, is it difficult to get at the coil?
  • elroy5elroy5 Posts: 3,741
    Remove the four nuts holding the coil cover on (cover on top of the engine, with four chrome nuts) . Remove the bolts holding the coils down, then unplug the wire connectors by releasing the locking tabs on the connectors. Pull the coils out gently. You will need a spark plug socket to get the plugs out (I prefer the magnetic type). Any questions? The procedure is in the 03 owner's manual, but I don't know if your manual has this. Good luck.

    ...I'm wondering if any of you guys have any ideas about how much repairs might cost to replace the front bumper and a smashed headlight? I was recently involved in a minor accident and sheared off my front bumper as well as smashed a headlight.

    I've been trying to get in touch with the repair facility and they haven't had time to really respond. I'm just curious if you have any ideas so I can know what to expect.

    I'm wondering if winter tires are in order?
  • I've parked my 04 Accord in the garage and don't drive it for the winter due to the use of road salt here in WI. I leave the battery in, start it once a month, and keep a battery maintainer trickle charger connected between starts. This has worked fine and have done this since the car was new. I had noticed in late fall the hygrometer "eye" was showing yellow even after driving the car for hours. I did check the water level, and it was fine. I planned on changing the battery in Spring, and will let the old one stay while in storage.

    Well today I decided to change oil on my winter truck, and since it was 16 degrees outside, I figured I'd do it in the garage and turn the furnace on. I needed to back out the Accord for the room. Although it wasn't a total surprise, when I hit the key in the Accord, the battery was dead. I still wanted to use the garage, but I don't want to jump start a frozen battery, so I took it out as well as the plastic battery box. I got another older and much larger battery that I kept when I replaced the battery in my winter truck, and figured I would try to see if it fits. I was surprised that not only did it fit in the car without the box, but there was room to spare. I was able to use it to get the car started.

    So, now that I see there is alot of room without the Factory battery box, am I asking for trouble if I upgraded to a larger battery? I would need to find another battery tray, and would loose the factory box. I would also need to change the top clamp to a wider one, but may be able to use the factory hold down bolts since the metal factory tray is wide enough that the holes for the hooks are still visible. I would have to do some measuring to make sure I could close the hood completely.

    The only thing I'm concerned about is heat. The factory box may help reduce the battery heat, but it doesn't have any intake duct on it to draw in cooler air, so I wonder how much it really does. Since my Accord is an I4, there isn't much close by that's radiating heat except for the radiator/condenser.

    Even if I don't upgrade to a larger battery, it's nice to know that in a pinch, a larger battery does fit.

    I have priced a new bumper a few times (might has a whole and some cracks from a parking lot bump). To do it right, it was ~$600 for a new piece, painted and installed (unfortunately Honda doesn't sell them pre painted, in which case it would be a DIY project).

    The headlight unit? Well, with the bumper off, it should be a pretty easy change out, but I am guessing the part is expensive.

    Oh, not really. Quick google search, and found a place that has it for about $65, shipped free. Even has a bulb. Easy to install too.


    For the battery, I just replaced mine, and was surprised that I could only get a lower line (440CCA) model at walmart. None of the fancier 600+ ones like I put in my Odyssey.

    If you have an '04 on the original POC, it is way past it's expiration date!

    2019 Acura TLX A-spec 4 cyl. (mine), and 2013 Acura RDX AWD (wife's)

    Battery -

    The distilled water addition seems to have done the trick my battery started the car this am in -30 degrees (no wind chill). When I priced batteries at Walmart they had an $80 battery for the Accord with higher cca.

    Ironic - I just hit a deer the other day and not too much damage, but it was the bumper cover and one headlight. I will know exactly how much it costs as soon as I hear back from insurance. I will probably do the repairs myself to save a little dough. I will have the cover painted professionally though.
