So, I had a few questions. My car rolled over to 100k (100,705 Miles). I haven't driven it in a 1-2 years due to some health/life issues. Car came out of South Florida when I purchased it in 2017 with 56k miles. I live in the Midwest (aka Rust Belt, Salt Belt, Brine Belt). At that time I had the automatic transmission fluid changed, new tires, and I've had the brakes replaced. Also, replaced some of the coils. That being said, I'm thinking of trying to get this car back on the road. The battery is bad and has a bad cell anyways.

I'm thinking of changing the transmission fluid again, the vale covers/gaskets, coolant, spark plugs, and tires again. At this mileage is there anything else I should change? Everything on the car is pretty much OEM Nissan that came on the car. It's stock even with the factory exhaust,struts, and still has I think the factory hoses and such. I don't beat it on and a lot of my miles are highway miles and rarely run over 2,200 rpm most of the time.

Also, is there any upgrades I should do at this mileage? I know the catalytic converters are a culprit on these so, I do try to watch the oil level since I do have a leak(s) anyways. Thank you in advance again.

 

I would flush the brakes and install new brake fluid! The spark plugs weren't changed when you changed the coil packs?

 

I think my brake fluid is good. Not long after I got the car both rear calipers and all brakes were replace and I think they replaced the brake fluid then. I replaced pads and rotors again a few years ago. I didn't change the plugs because when I replaced the coils I want to say the car had maybe 70k-80k miles on it. I got a code on two different cylinders for a misfire weeks apart so, I replaced the coils which took care of that. I think I ended up replacing all coils with Hitachi then. If I get this car back on the road I have a lot of work to do as it has sat for a while and I've not driven it because of health and life issues so, it's been easier driving another car. Thank you again.

 

I would do nothing special outside of the recommended service intervals in the factory manual. Play it by ear, change all the fluids at the recommended time. As far as coil packs go, I must have committed the ultimate sin of only replacing the one faulty coil pack that was misfiring...

 

Look at your accessory drive belt, drive axle boots, and maybe change your P/S fluid as stated about just stick to the recommended maintenance intervals for those items listed and go from there.

when it comes to changing the power steering fluid, be prepared to possibly have a leak.

years back when I changed out my power steering fluid I eventually started getting a leak from the front shaft seal of the pump right behind the pulley. having new fluid will raise the system pressure back to normal so leaks may occur. same thing happened to my van last week after changing the reservoir hoses and changing the old fluid out.
