Servicing fluids

[crisfer]

When do you need to replace??
1. Power steering fluid miles /months?
2. Brake fluid miles /months?
3. Automatic Transmission fluid miles /months?
4. Differential oil miles /months?
5. Engine coolant it states in the manual first change at 60K then 90K and 120K.
ATF and Diff manual states at 30K if you do premium service upgrade but still excludes seven speed auto?

One last question how do you check the ATF to see if it requires a change?
I do understand that such things as tires ,brake pads, alignment etc. have no exact interval they just need to be serviced/replaced when they are needed but does this apply to any of the above fluids?

Thanks

Friend, you have asked essentially the same question three times in two different threads. Are you going to keep asking until you get an answer you like or do you just not believe anyone?

Way, way more than 30K.

5. Engine coolant it states in the manual first change at 60K then 90K and 120K.

Go with the manual. This is the one that does need to get changed.

ATF and Diff manual states at 30K if you do premium service upgrade but still excludes seven speed auto?

Under anything like normal usage don't even think about these anytime soon.

Thanks for the reply was just wanting to get mirage and time on when I should replace these fluids the dealer made me think I was curding damage to the car by not doing them so I figured someone would have the mileage/time I needed to replace these fluids.

You can not check the fluid in the 7AT, so you're going to have to estimate when it is time to change it. It's supposed to be "lifetime" transmission fluid so it will last a while under normal driving conditions.

If you're a pretty average driver, ask your Infiniti dealer to flush and replace the fluid at ~65,000 - 75,000 miles. If you have a lead foot, maybe 45 or 50k.

Infiniti specifically made the transmission difficult for DIY fluid changes because 90% of people do it wrong and mess up the transmission (and probably they want to make more money off us).

After calling several dealers the consensus was they like to push encourage premium upgrade at 30K where they will replace ATF and Diff oil as wells and replace drive belts but if you choose not to do premium then they all strongly recommended doing ATF at 60K and replacing all other fluids /items such as brake,Diff,PS and belts after they have been inspected and deemed necessary to replace.

60K to replace ATF fluid seems like such a long time! Its 60K or 48 months right? I guess I was just use to older cars where they needed ATF at 30K when they use to not use synthetic fluids that could last 60K...

[IN.G37]

PS 60K 48 months
Brake 60K 48 months
ATF 60K 48 months
Diff oil 60K 48 months
Drive Belts as needed
Engine coolant 60K 48 months every 30K after that as stated in manual
oil and filter every 3750 miles at stated in manual
engine air filters every 30K stated in manual
in cabin filter every 15K as stated in manual

Have the dealer point out to you in the non-premium part of the manual where Infiniti recommends these services. The premium service is designed to induce people to service their vehicles more often than when the fluids were designed to be replaced.

It might make a difference if your car is under a powertrain warranty, so that if you have a powertrain issue you can show the vehicle was maintained on a decent basis, but if there is no more warranty, that's a different story. Take it someplace other than the dealer.

oil and filter every 3750 miles at stated in manuall

Absolute BS. Decent quality/name brand oil & filter every 7-8K and your car will live forever.

Infiniti gives rather clear direction as to whether the service schedule should be I (3750/3mo) or II (7500/6mo). Absolute BS to say either one is correct without knowing the usage pattern of the car.

But dealers will often try to steer you to all sorts of BS that is neither recommended nor required by the manufacturer. This is hardly limited to Infiniti dealers.
