| I currently have about 53,000 miles on my 2003 murano. What are the important car parts changed when my car's mileage is 60,000. If I follow the nissan schedule (Major Maintenance) some of the work the nissan dealership is probably not necessary. I love my murano and want to take care what is really important. Thanks |

At 60K I intend to change the CVT fluid.

| Just do whatever the maintenance schedule in your owners manual recommends. A CVT fluid change is not a bad idea either. |

| If the fluid is clean, doesn't smell burnt, and passes the built in sensor test, why change it? |
|
|
| hfelknor |
Well, even if it passes, it won't measure like new. And you won't know the rate of deterioration......And then when the CVT fails, it might fail the test.....too late.
Preventative maintenance is a good thing IMO.

how about replacing the following murano parts:
1. upper and lower hoses (radiator hoses)
2. fuel fliter
3. drive belt (serpentine Belt)
4. cvt transmision fluid?
If I am missing anything let me know. Thanks! |

The Murano doesn't really have a replacable fuel filter per se, but rather its part of the fuel pump assembly. The FSM says this is "not a servicable part." |

If you have not flushed the cooling system, I'd do so.
Brake pads? Make sure you have enough meat on there, you don't want to go back in a few thousand miles for new ones. A new air filter goes without saying and that micro-filter probably needs a looks see. We have many threads about doing that yourself and there is no way I'm paying someone 60-70-80 bucks for a change on that micro that you can do yourself in 15 minutes without as much as a screwdriver. |

The CVT electronics contain an algorythm that calculates theoretical wear of the CVT fluid. The calculated wear figure can be read using the CONSULT-II. The Service Manual states the following:
"CVTF DETERIORATION DATE"
More than 210000: It is necessary to change the CVT fluid.
Less than 210000: It is not necessary to change the CVT fluid.
The 210000 represents a "unit-less" value.
From earlier posts, no MO has yet to come even close to the 210000 figure. That can mean one of two things - the Nissan CVT fluid is superbly engineered for the task (which is entirely possible) or the 210000 figure is overly-optimistic. I am hoping for the former.

I teach "Condition Based Maintenence" as a way of optimizing maintenence cost and imroving reliability. So I do believe that CVT fluid can be tested and based on the results changed ot or not.
njjoe,
the number means notihing to me. We just have to trust Nissan that they did devised a proper test and the number has some meaning. 210000 does seem high but it is just a number. Who knows what in this case is high and what is low.
When 60,000 come I intend to do normal maintenance as per Nissan schedule. |

What exactly is CONSULT II? Never heard of it...

| CONSULT-II is the name for the Nissan scan tool. |

| I just had my 60K service this weekend, and had them test the CVT fluid. My reading came in at 9,690. Based on this reading, and assuming the same rate of deterioration, I shouldn't have to change my CVT fluid for a few million miles or so. Wouldn't it be nice if this was the case? |

I'm sticking to my own theory that says there is just not a whole lot of stuff going on in the CVT. Couple a belts, a couple of cones. Nothing like a convention tranny with all the gears and clutches.
I'll say, if it ain't broke, don't fix it. :25:

Gonzo, see njjoe's earlier post in this thread.
"The calculated wear figure can be read using the CONSULT-II."
How can they get an accurate reading from this? Wouldn't they need to actually test the fluid, and not base it on a calculation? |

Gonzo-
According to the 2005 service manual, when interrogating the CVT using the CONSULT-II diagnostic tool, if the value in the field called "CVTF DETERIORATION DATE" exceeds 210,000 then "it is necessary" to change the CVT fluid.

Sure would like to know how they determine that 210,000 number.
The guy that designed the algorithm is not going to help you pay for the new tyranny if the algorithm is wrong, or if the algorithm is ok for most cars....but not YOURS.
If it truly is an arithmetic result of some digitized parameters. and not an actual testing of the fluid, then I will change my position from "I will change at 60K" to fist pounding on the table, shouting to the sky, recommending that everybody change their tranny fluid at 60K ........AS IS RECOMMENDED BY EVERY TRANNY GUY THAT I EVER MET, WITH ANY AUTO TRANNY.

........AS IS RECOMMENDED BY EVERY TRANNY GUY THAT I EVER MET, WITH ANY AUTO TRANNY.
Homer, I do agree with that theory with any automatic tranny.
I'm not so sure about this issue with a CVT. I was also reluctant when told some years back that our plugs can last till...what is it up to 75, 85, 105000 miles?? I was convinced years ago that we had to change them every 15 or 20K. I slowly came to grips with the fact that I did not need to do that with the new autos. Maybe we are all in a learning curve on this issue.:8:

So you recommend gambling?
Remind me to never play Texas Hold em with you. :D
There's just a teeny little difference in risk between a spark plug and Nissan's CVT......... :D
Homer
BTW _ have you ever actually changed plugs at <> 100K miles?
I haven't.
BUT I did have a car with a 100K plug warranty and I decided to check them at <> 60K.
One plug had "become one" with the head. devil of a time getting it out. It finally broke. And I finally got it out. The anode was good. All the other plugs were put back in, and all plugs were swathed in anti seizing compound............for the next guy. |

If Amsoil has been able to develop a motor oil that can last 35,000 miles, why is hard to believe that Nissan and/or Jatco came up with a tranny fluid that can last 100K or 150K miles?
This CVT has less rolling elements and heat-producing clutches than your typical automatic transmission. The CVT fluid is working in a cleaner, less harsh environment. It is no surprise to me that the service interval is what it is.
Changing the CVT fluid at 60K miles is fine. Just like changing the engine oil at earlier than required intervals, it does no harm (except to your wallet) and if it gives you peace of mind then it can be justified.
As far as my MO is concerned, I may consider changing the CVT fluid if I still have her at 100K miles.

Or, the figure has nothing to do with the quality of the CVT fluid, but a calculated number based on how long and how hard the CVT has worked since that last fluid change? |

I changed my CVT fluid at 30,000 miles. Excessive? Perhaps. It came out amber brown, not the clear green the new fluid comes as. Why was it brown? Dirt? Oxidation? Transmission wear? I don't know.
But I wouldn't want to find the fluid coming out BLACK at 60k miles.
BTW, I am very easy on my transmission, and rarely use Ds (maybe a dozen times over 30,000 miles).
I figure $140 worth of fluid is cheap maintenance for a $5000 transmission.
(I just noticed that was a "homer" style one sentence per line reply - I guess its rubbing off on me). :p |

Kris, after reading that original post, I went to the garage and checked mine out. It was very clear and almost unreadable on the stick as it was so transparent.
Homer, I don't have a good poker face to ever take you up on that card game.

Something I noticed is that even though the fluid that drained out was brown (actually amber, like new motor oil), when I checked it beforehand using the dipstick, it looked clear, even on the paper towel. So I don't think the dipstick is the definitive means of seeing what color the CVT fluid actually is (in large quantities). |

| I let dealer change CVT fluid and belts at 60,000 miles. I do not know what the number was but I was intending to do it anyway. 60k miles is a lot. I do believe in prevention hence the change. |
|
|
| Nizmo |
What about MO with low miles on them.
Let say 10k but 2 1/2 years old.
When would be good time to change CVT fluid and Belts.
4 years, 5 years, or don't matter~ stick to 60k?

Sounds like the mileage my wife's car does.
I just replaced the belts on her 97 Sentra last year--first time, 62k miles. I think my oldest son may have this car till 2015. LOL
I would just have the radiator flushed. Belts are good for easily 50k miles, I've seen serpentine belts snap, but they had over 90k miles on them. The tranny hasn't even broken a sweat with 10k on it. |
|

| Kris |
I would agree with mgthe3. After 3 years, with low mileage as yours I would just change the cooling fluid. And of course inspect quite a few items.
Question to experts:
When one would flash/change brake and power steering fluids? |
|
|
| hfelknor |
Never thot about PS......
But brake fluid should be changed avery 24-36 months.
It matters not how many miles.
The darned stuff attracts water and that breaks down some of the elements in the fluid and also lowers the boiling temp.
My BMW manual recos 24 months. Course, they are fanatics........
