I know these questions were asked 100 times but I find as many answers as there are questions. I just reached 60k miles and looking to replace following fluids. I can get 30% off dealer OEM fluids but if you recommend using something other than OEM or specs that I should be watching out for please let me know. I have a 2004 G35 AT coupe

-Transmission fluid frain 4-5 qt Matic-S (I am assuming the current fluid is j-matic, so it is ok to mix ??)
-Brake fluid (how much do I need and specs?)
-Steering fluid (how much do I need and specs?)
-Differential fluid front and back (how much do I need and specs?)
-Transfer case (Should I change this ?)

Thanks alot

 

If you're doing a complete flush you'll need like 10 quarts of ATF. If it's just a drain and fill, 4-5 will be fine. S-Matic is the updated version of J-Matic. I think it should be fine to mix. As far as I am aware, J Matic has been discontinued so if you get it, it'll be whatever stock is left over.

Brake fluid you can do OEM or a lot of people use Motul RBF600. It's pricey but it's worth it. It takes a little over a quart to do that (2 500ml bottles)

PSF you'll just wanna do D-Matic ATF. 2 quarts will suffice for a flush.

A lot of people use Amsoil SEvere Gear for the differential. It seems to be the most popular. 2 quarts of that and you're good to go.


I would also flush the coolant and look into Seafoam. After Seafoam, change the motor oil and you'll have a car with complete new fluids =]

 

Thanks alot for the answers. I agree about doing just drain and fill

Just did motor oil change last weekend

Is it only rear differential in RWD right ?
Also how about transfer case fluild ?
And is there any preference for the coolant ?

 

I just called my infiniti dealer and they are assuring me that they carry J-matic and not matic s. I thought j-matic was phased out

Tranny J Matic 12$/L
Differential 7$/L
Steering 7$/L
Brakes 8$/L
Transfer case 8$/L

 

Great info, I am fast approaching 60k so thanks for the advice!!

 

Haha, your dealer must be confused =X

Since you have a coupe, there is no front diff or transfer case fluid =D. Those are only for the g35X sedans. ;D

I use the OEM coolant from Nissan. Any is fine though except DexCool. Avoid that.

 

For coolant and trans, use only OEM fluids. For a drain on the radiator, you'll only drain a gallon. For the trans, you'll need 4 qts if you just drain. It will take about 3.5 to refill.

As stated above: 1L for brakes, 2Qts for PS, and 2Qts for diff (but you'll only use 1.5ish).

 

These question have been asked far more than 100 times. I wouldn't worry about your transfer case/front differential, you don't have either! The 60K mile service is exactly the same as the 30K mile and the same fluids should be used. You need to quit reading 4X4 magazines unless you're driving one....are you?

Your comments are acerbic - not only in this thread - but many others. People on the forum may ask redundant questions, but they don't need to hear your rhetorics.

I reply to some posts I know have been answered in other threads before only because it will help someone out. I'm sure you got your knowlege of the V35 platform purely from asking questions never posed before .

 

No actually AuAltima3.5 I got my knowledge from working on cars over the past half a century! Krypton the member that started this thread stated this subject had been asked a 100 times, I was only confirming his statement. Don't get your panties in a wad....SEARCH is everyones friend!

Thanks for the great info everyone

 

Lotta weird people on this forum.

 

lol

 

we all meet in the interwebs... LOL

surprised i havent heard anyone mention blinker fluid.

 

60k is dur for me in about 700 miles. I have a 05' 6speed Coupe. Shop wanted 600 to do fluids and spark plugs, but im assuming they would use shitty fluid and low grade plugs. This is my first G35 so any help on types of fluids and spark plugs and if I should just attempt some stuff myself would help!
