Correct Timing belt kit code
 

I am getting a lot of problem to found the correct timing belt and seal kit for a matrix 1.8 2002 gasoline.

some seller gave me belt with incorrect number of theet:113 and incorrect diameter of seal.

do you know how get the correct code of auto parts.?
Thanks in advance

If you have a dealership around ,you should be able to get the correct parts.
If not,you might still be able to get the part numbers from a dealer and cross them over to where you are purchasing a replacement.
