It's time for me to do my 90k service on my 03 G35 6MT coupe.

At 60k, I did the full battery of maintenance at the dealership. (And it cost me about $1000 w/ drive belts replaced).

I had all of the following done, and I want to know if you think it's OK to skip until 120k:

--Changing differential oil
--Changing manual transmission oil
--Flushing coolant
--Bleed brake lines
--Fuel injection flush
--Power steering flush

Please let me know if you think these can/should wait until 90k -- and if there are any that i really should go ahead and do now.

Thanks!

 

check here for some info

 

i've read all of that. i understand the difference between s1&2/premium -- most of these are not included in premium, which tells me i can skip them without consequence.

but i wanted to check with you all...

 

imo peace of mind is worth the extra dollar.

 

In principle, I agree -- but we're not talking an extra dollar or two, we're talking the difference between a couple hundred dollars and a thousand. That's why I want to know what I really should be doing, and what is maybe unnecessary at this particular point.

Eg. if you think changing the transmission fluid, differential fluid and flushing the coolant are especially important to make sure I do right now -- I'd be very appreciative if you could let me know your thoughts.

Thanks!

Changing the trans(drain and fill) and diff is very very easy. I haven't done the coolant but I cant imagine it would be that difficult. I vote you DIY and spend under $100

 

+1 on the DIY. I used to read threads like this when I was coming up on my 60k maintenance and be like "no way I'm doing this all by myself".

The truth is, with all the resources on this site (most importantly bythabay's DIY videos) it's really easy. I am not mechanically inclined at all and had not done any work on a car before aside from installing my clear corners Now I've changed my own oil several times, drained and filled my tranny fluid twice, replaced my air filter and will be doing coolant and differential service shortly. For way under the price from the dealer you can get yourself the fluids etc. and some decent tools (if you don't have them already) and be saving yourself a ton of money for the rest of the life of the car.

You'll feel great after a nice DIY sesh too. Go for it!
