Dealership said the timing belt tensioner is leaking. on 2003 Toyota Corolla

Should I have the tensioner tightened up or have the whole timing belt replaced.

Asked by for the 2003 Toyota Corolla
Think it has a chain. Have ALL timing componets replaced. Too much lobor involved to have to do it again later if another original part fails!
I agree with Pushrod.

replace the whole assm to save time and money in the long run
The tensioner is hydraulic; Can not tighten, when it leaks, it needs to be replaced. As far as replacing the timing belt, if you have at 60,000 or more miles on it, probably good idea. It's always better to be safe then sorry.
