@ chinyoti: yeah maybe ur talking in light of user manuals and your personal experience... well i was saying this because here in Saudi Arabia i use to take my car at a tunning specialist who was earlier worked as a carburator specialist at toyota motors and he use to advise me this.. and i kept this practise with all rides i have in pakistan and saudi arabia .. anywaz i ll do some good research in this regard and come up with an accurate milage when to change the timming belts...
please let me know how you can say we have to change it after 1000000 km..
we all here are to learn and deliver our experiences so its healthy if we get our things cleared im just asking u to get accurate and precise knowledge in this regard.. anywaz nice informative thread initiated by u
