Mazda CX-7 Maintenance



  • nmknmk Posts: 111
    How can I obtain manuals for the CX-7 other than the owners manual. Just in the event that I am willing peek under the sheet metal and hood.

    Try putting your hand on the right side of the hood, in the area where the hood becomes the fender.

    After driving a bit, let the vehicle sit for about 5 minutes. Something in that area is red hot and heats up the hood to extremely high temperatures. With no wind to dissipate the heat the hood area becomes hot, hot, hot....

    I'm wondering if this will cause paint failure over time over that part of the sheet metal.

    Can anyone confirm that this is happening on their CX-7 ?

    I've noticed the same thing, but I'm not too concerned about it. The hood on my 04 Santa FE feels very hot in certain spots as well.

    I'm not certain where the source of the heat comes from. You may want to pop the hood and try to deduce the source.

  • How oftern are you going to change the oil on the Cx-7 and how critical is it to use synthetic concerning the turbo design?
  • My father gave me a horribly anal (and expensive) instinct for overdoing maintenance on every car like I plan on owning the thing until it falls apart. However, I have yet to keep a vehicle for more than ten years.

    That being said, I'm changing the oil every 7500 miles per the Mazda manual, but using synthetic oil because it removes all the fear of turbo problems for me personally. Maybe it's overkill, especially if you are just going to swap your Mazda in 5 years or so.

    I also drive like a maniac and treat the throttle basically as an on/off switch, so I figure treating the hard-working engine to some gourmet oil is not a bad idea.

    There are plenty of good non-synthetic oils out there that will meet the warranty requirements, so unless you are a nut like me or planning to keep the car forever, I'd just follow the book.

  • You saved me some hassle with the oil level. I filled it with 5 quarts, started the engine, then let the oil settle. It was about 1/2 quart low. Put another 1/2 quart in it and it's right on the money.

    For oil/filter change use 5 and 1/2 quarts. 6 is too much.
  • I have the CX-7 GT with HID xenon headlights and there's a really bad line between dark and light on the low beams that's really annoying. At about 20 feet out it sits about 3 feet from the ground and it's not straight - it has a severe jag in it that appears to be from the hood line. Never having had a car with these kind of headlights, is this normal for HIDs or do they need to be adjusted so the dark/light line is higher or less visible? Anyone else notice this?

    Yes, I have noticed it, and while it took getting used to, it doesn't bother me. I don't find it inhibits visibility and apparently, I'm not blinding all the people in front of me on the road.

    You can adjust it. There's a dial on your dashboard to the left of the steering well for adjusting. Default it 0 (so if yours is already set at 0 that's the highest they'll go). 1-5 incrementally make the lights lower (and this is apparently for when you're carrying more people or a big load of cargo).
  • It's normal for the'll get used to it. The high beam on the right is slightly higher than the one on the left, hence the "jag." Only thing I can think is the right side can be a little higher to give you better vision without blinding oncoming cars.
  • Does this 2.3L engine use a timing belt or chain? What service interval if any. Thanks Ed
  • The Cx-7 has a chain drive. Not much service is required on that. Mainly, it would be important to change the oil every 3750 miles, change the transmission fluid, air filter every 20 to 30,ooo and keep the tires at the proper psi level.
  • None of your mileage intervals are even close to what Mazda recommends. They are much more conservative. Is this your professional opinion because you are an auto mechanic and want to hold on to your CX-7 for 30 years, or are you making this up?

    No offense intended, just trying to learn why you would change the oil or transmission fluid so often. I've been caring for cars for more than 20 years, and most of them were a lot less reliable than my Mazda - and I've never had any problems related to changing the fluids based on what the manufacturer told me to do.

    If you want to be conservative, I'd switch to synthetic oil because this is a turbo and change it out every 7,500 miles per Mazda. As for the transmission, I'd have to go look at the manual, but I'd be surprised if the interval was less than 60,000 miles. Many manufacturers are up to 100,000 miles these days.

    The manufacturer (dealer, at least) stands to make more money off service if they give you conservative intervals, so there's no reason to not trust the guys who engineered the vehicle when it comes to changing fluids.
  • Anyone that goes 60,000+ between transmission fluid changes is asking for trouble down the road. If you are leasing the vehicle, then of course that is another matter, you for the most part don't have to change anything. The vehicle is given back in 2~3 years. However, if the driver plans on keeping the vehicle, regular maintenance is a must. I'm no auto mechanic, but have seen fresh tranny fluid compared to some at 40 ~50,000, and the difference is amazing! I used to drive an Audi A6, and the factory even stated "lifetime" on the tiptronic transmission fluid. The factory is wrong. Every Audi mechanic I conversed with recommends regular (every 30 to 40,000) mile changes. They are seeing trouble with these transmissions at the 60 to 80 mark with unchanged fluid. Why would the Mazda be any different?

    As far as oil, using synthetic is always a good idea, I would agree. Considering the cost ratio, changing the standard oil at a more frequent rate should come out about the same. Any good mechanic will tell you that the oil should be changed BEFORE it gets dirty. Here in Minnesota, with cold and short tripping, changing at about 4,000 miles is just plain good maintenance.Oil changes are the least expensive most effective way to prolong engine life, no matter how frequent.
  • Fair enough. But I still say it's overkill for anyone purchasing a car and keeping it for a reasonable period. My personal experiences following the factory bear that out. I almost bought an A4 back when they looked decent, but otherwise never touched an Audi.

    And sure, in a perfect world, all the fluids in every car would be pristine every time you started it up. But that ain't practical. And just because there is a visible difference between new fluid and old doesn't mean it's destroying engine/tranny components. A lot of times in life, "less than perfect" is good enough for what we need.

    If you can afford to stick by the schedules these "good mechanics" are feeding you, more power to you. Good luck.
  • Anyone that can afford a 28,000+ MAzda Cx-7 can afford to spend $35.00 to change the oil every 4,000 mil;es or so and can afford a $100.00 transmission flush every 25 to 30,ooo miles.

    Of course, it is impossible to keep the fluids perfectly clean at all times, relatively inexpensive regular changes will help prolong the life of the vehicle.

    I drove an Audi for 6 years/100,000 miles and it really was a maintenance nightmare. Hoping that my new Cx-7 will need much less the next 6+years. At 2700 miles, no problems to report except the gas cap replacement. Just filled up with fuel yesterday and achieved 18.61 mpg at 100% in town driving.

    That's a kind of judgmental generalization, and I disagree. But we're not gonna convince each other. So... I'll volunteer to be your control group. (and I'm sure you can find others as well) I'll follow the manufacturer's recommendations religiously (although I've already admitted that I'm using Mobil 1) and let's compare notes in 5 years, and then again at 10. If my CX-7 transmission goes south or my engine bombs, I'll send you a gift card for a dinner.

    May the best person win... ;)

    I bet your odds of winning would be just as good running regular oil too. :D
  • I don't have any doubt that synthetic is an excellent way to go, especially with the turbo.But INMHO, changing more frequently with standard dino oil, changing the oil/filter BEFORE they get too dirty, is also an effective maintenance tool. Remember, even with synthetic , the filter can become ineffective and need changing before the 7500 mile mark.

    Would be interesting if Mazda or others would install a sort of "filter gauge" to test how clogged it really is at a specific mileage point.

    I agree with your test report idea about 5 and 10 years out. That J.D. Power stuff about the "first 90 days" of ownership is mostly fluff. Let J.D. poll owners who have driven for 3 years, 5 years and 10 years, (does anyone keep a vehicle for 5 years, much less 10 years, anymore?) and see what the driving impressions are at that time.

    I'll be keeping my Cx-7 for atleast 6 years, it will take that long to pay for it!

    I did more than follow manufacturer guidelines on my Audi A6, and it still fell apart. 2800 trouble-free miles on the Cx-7 so far (purchased 10.24.06), only the gas cap replacement issue, just 97,000 miles to go.

    Yesterday in the mail I received a reminder from Mazda that my CX-7 is due for its 7500 mile servicing (they were pretty close; I've got 7380 miles as of this morning!).

    Has anyone done this service? What does it entail? The service department of my dealership isn't open on Saturdays (grr!! :mad:), and they're an hour from my place of work. I want to take the best care I can of the car and will likely "sacrifice" an hour of work to have the car serviced, but I'm just curious if anyone's done this yet. I had the first oil change done back in October at 4200 miles, so should I have them change it again as long as I'm there? Any input, thoughts are appreciated!
  • wjbushsrwjbushsr Posts: 135
    I seem to recall them doing a full inspection of the entire car, including checking the computer. The print out was extensive, and mostly under the hood stuff.

    On a side note, waiting til 4200 to have the oil changed the first time was risky at best. {lots of metal particles that needed to be flushed out} Mazda and the other builders use your oil change intervals as a way of shooting down warranty claims.
