Hey all,

I have a 2009 G37X sedan which just hit 50,000 miles.

I need an oil change so when I am there I'm also having the coolant flushed. Never done before. Not so green anymore.

I know I need brakes soon but I will probably leave that for a buddy of mine to do.

Battery is holding up fine. Tires are good.

The drive belt looks fine but has never been replaced. I know it says every 30k but is that true? Can't I get 60k out of it?

Anything else? Fuel filter?

I'm a bit of a newbie. Not like my Saab.

Change the Air and cabin filters yourself. Very easy to do

Oil and filter change

Coolant not necessary

If you still have the original battery replace it

Fuel filter not necessary

I'm at 55000 miles

14 oil and filter changes thus far.

Latest one was yesterday.

He loves visiting the dealer checking out the new cars and the free cookies, crayons, and coloring book.



I change my air filters every 8 to 10k miles and the cabin filter once a year

Drive belt is fine for at least 60k. Mine hasn't been replaced and the condition is great.

Cabin air filter and engine air filter are DIYs
Brake changes are DIY. If you can change a tire, you can change brakes - there are plenty of DIYs available for this - even videos within YouTube.

I'm about to hit 60k and will be changing all my drive fluids - front + rear differential, transfer case (AWD models only) and transmission. Infiniti says these are lifetime fluids (8 year or 120,000 miles) but I take that with a grain of salt. Fresh fluids allows all the components to operate more efficiently and cooler. This can be a pretty penny at the dealership but if you have someone who does work on the side, all three fluids can be changes in under an hour.

Other than that, get your oil change, change filters, brakes, and keep driving the car.

Do you not typically machine the rotors when replacing pads?

I had tentatively planned on buying a second set of rotors and swapping them out with each brake pad change…the old rotors go to get machined, and are ready for the next brake job to eliminate down-time.

If you replace your pads when they are supposed to be replaced, you should ever need to machine a rotor. If you let the pad get down to metal because you're too lazy/cheap to get the work done, you're spending unnecessary money machining or replacing your rotors.

Also be sure to change your brake fluid (a complete fluid flush) at least every couple years, moisture effects brake fluids' boiling point in a bad way.

Thank you all.

I have changed air filters out with K&N drop ins.

The cabin filter just this past summer. The tutorial video online was a big help.

Brakes I'll leave for my friend.

and I guess I'm good on the belt for now.



Does everyone else agree on the coolant. No need to flush it out at 50k?

and battery? Its still starting with out much problem in 5 degree temps here in NY.

I don't see the point of changing a battery that is working fine.

I also do my own periodic maintenance on my 2010. I rotate the tires, change the oil and filter and change the cabin and engine air filters.

The one thing I neglected for the first couple of years was the battery. I had become use to maintenance free batteries and the fact that the G didn't have one caught me by surprise. When I finally removed the caps to check the battery fluid it was pretty low. I had to put quite a bit of distilled water in to top off the cells and figured the battery wouldn't last long after my neglect. That was about 2 years ago and the battery is still working well.

I will have had my 2010 for 5 years in a few weeks and have had zero problems with it so far. That includes no rattles or complaints with the transmission.

I do the service according to the regular schedule in the owner's manual. The dealership will have you doing a lot of unnecessary service.

It is unusual for me to keep a car this long, but it meets all my needs and I have no desire yet to upgrade to a newer car.
The wife and have 2 cars and a motorcycle. My wife drives the other car, a 2014 SRX, I have traded in 3 of her vehicles during the same period I have owned the G37.

OP's car is 5-6 years old with 50K miles & he lives in chilly NY. If its the stock unit its at the end of its expected life span and if anything he's gotten more use out of it than many folks here. OEM battery warranty coverage is 4 year/60K, whichever comes first, so he has $0/0% pro-ration.

He can replace it now (which is what I'd do) or later, perhaps even in a dark closed restaurant parking lot on a Sunday night, while its snowing, with his wife and kids shivering/glaring at him from inside the cold car, with nothing but a leathermans tool. Atleast thats the way it worked for me.

I'll have the dealer test the battery while I'm there.

I may forgo the coolant flush I guess. I'll check the fluid again.

I'm used to my old Saab burning up coolant with the heat from the turbo.


I have more mileage than most of you guys?

I'm probably averaging about 10k miles a year or less. This is my only ride and I plan on putting on way more mileage.


Just to let you all know when I bought this car in May of '13 it had only 19,800 miles on it.

I plan on having this car (my dad and I love Infiniti's) till at least 200k miles.

Check the drivebelt carefully for fraying/cracks. I had one disintegrate at medium revs in my G35 at 52K miles. Belt was like $20, but it took out an A/C pipe when it left go and I had to pay $900 for replacement pipe and A/C re-charge.

Limmerbr

I checked the belt, looks fine.


PontiacGTO - do you still have your GTO; is it the Holden Monaro version?

My buddy has one, sick car. He's got it up to 550hp all motor.

Wish they still made that one.

Nope - driven a few (as well as G8 GT's) but never owned one. My handle comes from buying a collection of TA's a few years back and selling all but one that I kept for myself;

Agree. There is a simple test the dealer can run on the battery that can tell you if it's weak or not (they never charge for this if you are getting other work done). I have typically had to replace mine every 4 years or so, but I live in CA where the weather is very mild. Extreme hot/cold can shorten the life.

I have always changed the coolant every couple of years. At 50K miles, I would definitely have that done as it's cheap insurance for keeping the the coolant system in good shape. The VQ37 is also known for running a bit on the hot side.
