Hi folks... I just picked up my G37x, it has 77,000 miles on it. Just did an oil change (Synthetic oil + Factory oil filter). I'm going to change the brakes and rotors but what kind of preventive maintenance should I be doing at 77k? Spark plugs, coil packs (?), coolant flush, etc.... I need my car to be super reliable so I'd rather change parts now in my shop than on the side of the road in the dead of winter. I put it on the hoist and didn't see any oil leaks or rust or any issues around the exhaust. Half shafts (or axles) are all solid, no bearing issues in any corner. All looks good from a suspension perspective.

Thanks for your help, be kind. I'm not used to these sorts of cars lol...

 

do a drivline service, (front and rear Diffs, transfer case trans drain and fill) ...change up the the serpentine belt..if your wheel bearings are good theres not much else to look at, maybe clean the MAFs and look into cleaning the throttle bodies (just beware, if you get into cleaning the trottle bodies you may need to relearn idle and TPS poisiton which can be a headache...maybe enjoy the car for a while and get to this)

its a touch early for plugs but may be a good time to look at them to see if there is any unusual AF condition and change them anyways if you want, coil packs are usual trouble free...

 

Good idea... now to find out what oil to use... I'm sure it's been discussed a few thousand times so I'll search. Thanks

 

my Recco is Redline... Anything with high ester content keeps the top end noticiblly quiter...lots of people love penzoil and mobil one on here though and this engine seems to run fine with anything synthetic and changed frequently....driveline...Amisoil, redline, Motul Redline...all populay don't really matter...stick with nissan for the transfer case and the tranny though

 

Transmission flush is also due. Drain and fill is 4quarts I believe of matic s and transfer case is 2 quart and I believe its matic d might have these backwards As far as matic d And s but the dealer will tell you all the specs

 

Matic J for the transfer case, just bought a few bottles myself....
