My 2005 Civic with the generic engine now has 115,000KM after 30 months
of non-stop daily use. I put on about 50,000KM a year. Lot's of highway,
maybe 25% city driving. Looking for maintenance suggestions from people
with experience with the same generation of Civic.

From what I read here and various mechanics have suggested, I will do
the timing  belt very soon. The car has already had the horrible stock
15" tires replaced with way better Yokohama AVID TRZ's. I had a
"critical" dash light come on 3 months ago and Honda replaced one of the
Oxygen sensors (at my cost). I do regular oil changes and have had a
couple of litres of the AT fluid (genuine Honda) changed during some of
those oil changes.

Here in Canada it seems there are not a lot after-market parts available
yet (Timing belt and other tensioners and idlers). Could not even find a
  DYI manual in the stores last time I looked. I will need to keep this
car for at least three more years when in all likelihood it will have
around 250,000KM when I go to sell it.

Looking for what I need to do to it at this point in it's life to stay
trouble-free.  Some questions follow.

- Do I need to change the T/belt tensioner at this stage?

- Should the other Oxygen sensor be changed?

- Keep on changing out some of the AT fluid every couple of oil changes
or get a full change out at a dealer?

- What about the coolant and thermostat? I believe it is supposed to be
some sort of long-life (5 year?) coolant in it from the factory.

- How often should you change out the P.S. fluid?

Lot's of questions for one post, but I don't seem to see much about this
generation of Civic in the discussions here (yet). I had a 1992 Accord 4
cyl. for 300,000KM. It was rock-solid, but seemed like a much simpler
technology compared to this Civic. I feel I will need to be much more on
the ball with the pre-emptive maintenance on this car.

Thanks, Mike
