I still have the original hoses on my 93. I see no leak or visual defects anywhere. How much longer can it go? Is there a way to know when is the time to replace them? How long did yours last?

 

dude replace them OMG. its a twenty year old hose -___-

 

If they are starting to swell up around the edges, that means they are about to go boom. But they should be replaced routinely when the timing belt is done just for preventative measure.

how are you sure they are the originals?

 

this sounds exactly like something I would say!
