This tensioner has a bit of play in it where the bolt holds it to the car (bottom left bolt). Even the bolt head moves slightly with the whole tensioner. There is a small rubber seal that sits behind the tensioner as per separate pic. My serpentine and air con belt snapped yesterday, air con compressor seized up with driving. Trying to fit a new belt and guide pulley but found this main serpentine tensioner has a bit of play. It's only held onto the block by two bolts, bottom left and at the top of the spring part. Is this correct? Cheers.
