Found this on Ebay. For those of you who have gone nuts with the constant noise and failure of the hydraulic belt tensioner, this is a blessing. The Vibe isn't listed..... yet. They list Corolla (98-08) and Matrix (03-08), so I was sure it would fit the Vibe. And it does - I installed it on my '05. I called them, so they're changing the listing to include 03-08 Vibe. The pin you see at the bottom of the spring is for shipping - it falls out once you compress the spring to install the belt. One year warranty from the seller. Here's the link:
Nice find ... and a great price. Won't need one for awhile BUT when I start working on my project 2003 Vibe GT this fall, I'll keep this in mind if I need a new one. Thanks for sharing. Another reason this site is awesome !
