Hi,
bought a used 03 TL Type S. TIming belt and water pump was chaned by the seller. Car runs great. Since then I have done:

- Syn oil change
- new front rotors with brake oil flush
- coolant flush

Any other recommeded maint considering there is no service history available

Spark plugs should be changed?
Wires?
fuel system clean up flush?

 

basically all yes

and on said t/belt, where the bearings also done, or just the belt (and considering no records are available, i would just assume nothing has been done )

plugs, by 105k they are wasted, with 90k being about the right mileage to change them (they also come out easier too, because they have not quite yet started to sieze into the head)

fuel system clean, a couple of cans of BG 44k in the tank over a couple of tanks should do the trick (and one 01TL04 comes opn here, or whatever the old fuck's screen name is , will say seafoam too, which does not hurt at all, and depending on current condition of the motor can help quite a bit)

also clean those EGR passages too (and the idle air control too), they like to kinda plug up on our cars

 

that young prik fries and his bg lol
(red means sarcasm--often used among friends)

buy 2, 16oz $8 each cans of Seafoam at most parts stores or walmart has it
add 1 can to just under half tank of gas
drive
the low fuel light will come on at 3 gal remaining
refuel to half tank- add 2nd can

that will do all your internal cleaning of injectors etc
replace spark plugs with NGK Iridium IX at parts stores 8 bucks each
we dont have wires or cap/rotor,,each plug has a coil mounted on it! very cool~

see DIY section, 3rd item down the Main thread list you are on
for the EGR port cleaning-very important
