Stop starting so many new threads. All of the questions you have asked so far could have been combined in one post.
How would we know if you need to change the timing belt?
If someone said to you "yo dawg i got a ek9 do it ned a tming blt"?
How would you know if he needed a new timing belt? You would probably need to know how many miles are on the car, if the timing belt shows any signs of wear, etc. Next time you ask a question, provide all of the information.
