thank you
Every 5000 miles.
have you ever changed the fuel filter ?
Clogged fuel filter, dirty injectors, bad spark plugs (should be changed every 100K miles).
According to the 2003 Ford Focus Owner Guide ( for North America ) ( 5W-20 )
You should change the timing belt on the 2003 passat v6 after 100,000 miles is reached.
spark plugs are irridum and should be changed at 90-100k, trans fluid should be changed every 30k, coolant should be changed every 30k, srep belt should be changed when it starts cracking or starts to squeek
Yes.
For the 2003 1.8T Audi TT you should consider oil changes every 5,000 miles with full synthetic oil as turbo charged engines run hotter when enjoyed. Also, always change the oil filter when you change the oil.
The 2003 Ford Focus has 16 valves.
It must be changed every 100,000 miles on a 2004 and newer. On a 2003 and older it must be changed every 90,000 miles.
The 2003 Ford Focus has an inline 4 engine.
