Getting close to 60K on my '03. I have passed on previous dealer recommended service packages before because all they seem to do is "inspect" everything for hundreds of dollars. The 60K package includes an engine coolant flush, transmission flush, replace engine air filter(s), replace spark plugs, service throttle chamber, and most of the other "inspection" stuff. Is this service worth the cost or is it better to do those things individually? Thanks in advance for any info on this.

 

IMHO and from my experience, the engine coolant flush, tranny flush, air filter, spark plugs, and T/Body cleaning are all good investments and needed by 60k.
A lot of the other "inspections" are just fluff and can be done yourself.

It won't be cheap, but it will be worth it.

why replace the plugs aren't they suppose to be good for 100K?

 

60K is a good time for a "major service" especially because the G needs so little attention in the interim. If you've got the list of what's in a 60K service, take it to your neighborhood tune or tire shop and see what they do it for ... almost everybody is trying to get a piece of that business by saying they do factory scheduled maint now. Should be good enough to get dealers to finally drop their rates prett soon - I hope!

 

Depending on where you live, you may be able to find a shop where they have significant experience working on Nissans and Infinitis. I found a Volvo shop where I can get all the essential parts of a Volvo 60K service which includes almost exactly what the Infiniti recs do. It is run by a guy who has been working on Volvo only for 20 years and he charges $350 and uses Volvo plugs. The dealer wants over $600. I would not just take it to the nearest Tom, Dick or Harry though. Find a mechanic whose work you can verify with someone you know. I took a car to Sears once and they caused over $400 worth of damage changing the oil! Never again.

 

That's what they tell you but they begin to deteriorate long b4 that...........

High resistance, gap change due to wear, non-optimum gas mileage, and being stuck or frozen in aluminum heads are all good reasons to change your plugs well before 100k.

..and oh yeah, when new ones are installed, make sure the installer applies anti-seize on the threads and torques them properly.

This is a very good idea. I once had a car with a 4 cyl aluminum engine that I had just had a tune-up on. I was driving along thinking it was doing great when all of a sudden there was a loud noise and it sounded like the muffler had fallen off. I had no idea what had happened. I popped the hood and the plug had been ejected. The guy doing the tune-up must have cross-threaded the plug.
After I had it fixed and brought it home, I noticed a dent on the hood. I thought they had done it at the shop but it was convex. It was the plug hitting the inside of the hood so hard it cut through the padding and dented the crap out of the metal!
