Car Forum / Nissan / Nissan Maxima / March 200799 Maxima - 90K service
My 99 Maxima is hitting its 90k mile service and I was wondering what are the essential service items that I must perform; especially is it recommened to replace spark plugs?? The dealer guy is insisting that I change (costs $200) them but I am wondering if I should do or leave it for a while.... Also, what is the frequency of changing the fuel filter... I did change my fuel filter at 75K. Should I change it as well if it was changed jusy 15K miles prior.?? > My 99 Maxima is hitting its 90k mile service and I was wondering what > are the essential service items that I must perform; especially is it [quoted text clipped - 5 lines] > change my fuel filter at 75K.

I would change the fuel filter it's not a big cost item and they do fill up and put a strain on the fuel pump. What about the cooling system ever have it drained and re-filled? And the Transmission has fluid been replaced thats a real big item if it fails. >> My 99 Maxima is hitting its 90k mile service and I was wondering what >> are the essential service items that I must perform; especially is it [quoted text clipped - 11 lines] > What about the cooling system ever have it drained and re-filled? And the > Transmission has fluid been replaced thats a real big item if it fails. I agree. Coolant should be replaced every couple of years using a silicate free 'green' type. ATF or gear oil should be changed every 60k. Don't pay the extra money for a 'flush'. Dave >ATF or gear oil should be changed every 60k. Don't pay the extra money >for a 'flush'. My mechanic says to always do the ATF flush, otherwise you are only changing about 2/3 of the fluid. Any other opinions?  SignatureSteve Green >>ATF or gear oil should be changed every 60k.

I agree that an ATF drain and fill is about worthless, especially since the filter is about impossible to replace and rarely ever done. It replaces less than 1/2 of the fluid, whereas the flush should remove it ALL. -mike >> ATF or gear oil should be changed every 60k.

When I do a drain/replace I do change the complete fluid. I also drop the pan and change the filter if it's accessible. Each car is a little different, but there is generally a simple procedure where you can push thru 100% of the old fluid out of the torque converter and tranny cooler. Even if you don't know that procedure, getting 2/3 of it changed is still a substantial improvement. I don't advocate those 'power flush' things where they try to blast out every bit of grit in the tranny. That's the waste of money I suggest you avoid.

Pull cooler return line, run engine (need a helper), stop engine when it stops. Pull pan, change filter, refill. It's a very reasonable DIY on the car and truck I've maintenanced. And it clears 100% of the fluid. Dave >>>>> ATF or gear oil should be changed every 60k. Don't pay the extra >>>>> money for a 'flush'.

Plus the fact that most people wouldn't know which line is the return, and would likely damage it by running it dry. Most people should pay for the flush. |
