I've been looking on this forum to find the answer but I haven't came across anything so forgive me if the answer is already out there but I have a 2012 Maxima S with about 88k miles. I don't know the recommended service intervals but judging by my reduction engine performance and also mpg, I feel like it's time to give her some TLC. I would like to do the job myself and I know the spark plugs are gonna be a pain in the butt, but what else should I inspect/replace to give this engine a proper tune up???

Only other thing I can think of is a new air filter

 

Basic stuff.

Engine oil
Oil filter
Drive belt
Air filter
Plugs
Cabin air filter
Clean battery terminals and grounds
Radiator fluid
CVT fluid

Lastly, general visual inspection, repair/replace broken items noted and scan for and address codes.

 

I agree address all the above and you should be good to go, stick with the OEM Denso plugs if possible, and OEM belt, My experience with aftermarket belts hasn't been good.I always got a chirp after a few weeks of use, After installing an OEM one I never had a problem again.

 

Thank you for the help my fellow Maxima owners. I want to be able to hand this down to my daughter one day and I know these things are important.

 

What do you mean by plugs? The drain plugs for oil and trans pans?

 

Spark Plugs...this is for a tune up. The plugs for your pans (oil and trans) should last forever if you don't let folks with air guns do your oil changes!

 

Per FSM, trans and oil "washers" should be replaced with each plug open, but generally plugs should last the car lifetime (unless rounded by a careless garage)

 

I would add to that power steering and/or brake fluid if needed. I personally would wait on the plugs, those are just about a lifetime part. 120K at least before I would worry about pulling those. if you want you can just pull one from the front bank since it's easy, my guess is you will find that it looks like new.
