To clarify my 2016 Mazda6 at the time had a seeping water pump replaced under warranty.....since the tensioner was also leaking I complained to Mazda USA and they agreed to replace it (tensioner) too under warranty. Expect to get pushback from dealership.From 2 long threads I looked, I believe CX-5um is the only one said his leaking tensioner in his Mazda6 got replaced under new-car bumper-to-bumper warranty at 17k miles.
If the oil leaks out can it be replaced?.
Will leaking tensioner cause harm to other components?...I'm not sure but I did not want to take the chance. That said, I could've sworn somebody mentioned something about the tensioner having a tension spring inside and its filled with oil. I really want to know as well if the leakage is really something we should be concerned of. I mean, isn't the tension spring doing the real work?
Yes I think you can actually add oil into the tensioner. I have not tried myself but believe others did.If the oil leaks out can it be replaced?
Does the leak prevent the tensioner from applying tension?
His belt tensioner started making abnormal noises shortly after he re-oiled it. He said he’d learned from his error. And said replace the tensioner if it leaks.Yes I think you can actually add oil into the tensioner. I have not tried myself but believe others did.
Read post 18 here https://www.bobistheoilguy.com/foru...-tensioner-oil-leak-pics.252834/#post-4085061 Dude just popped open the black rubber top, removed some oil, added new hydraulic jack oil. Since the rubber grommet is not on tight, seepage can easily occur.
....................and then read post 22 and 23. He replaced it since it started making noise.
