I bought my 99 max auto with 38K miles on it about 6 months ago. The previous owner was an old guy who traded it in after the factory warranty ran up. Since buying it, I have changed over to synthetic, done the brakes, added a k&n drop in filter, new pulgs/coils, and cleaned TB/intake. I now have 45,000 miles on the car. It appears (since all services were logged in the manual), that he never had the tranny fluid or cooling fluids changed. I'm what you could call a moderately aggressive driver as well as a maintenance finatic. I'm wondering if I should definetly change these fluids at this time. The car is 7 years old at this point, I would assume it should be changed?

 

Yes.......

 

The transmission fluid should have been changed at 30K. The radiator should be flushed every 30K as well.

You didn't need to replace the spark plugs as soon as you did. I know the 99 Maximas have coil problems, but I doubt you had to replace all six given your mileage.

Sometimes one can be over **** about their cars.
