Hi,
I am new here and need help from any one who can help,my accent 09, i need to change timing belt, engine died while driving,after inspection, timing belt tooth some missing, how and what to check ?

 

If the belt broke while driving, the pistons probably hit the valves and you will need major head work and possible a new engine. Go to a trained mechanic to have the engine checked. This is not a repair for a shadetree mechanic.

How many miles were on the belt?

 

Your timing belt should be replaced every 50-70,000 miles. Carmakers have specified the replacement intervals for timing belts.
