Aux Belt Tensioner Rattle
Help with Aux Belt Tensioner Rattling!
Just bought a 156 jtd 16v (still got the 33 and 146 though) and after 10 days of ownership it developed a rattle at idle linked to alternator loading. The tensioner pulley was virbrating and rattling and causing the noise. So I just replaced it today but the new part does exactly the same thing - rattles and jumps around.
All I know is the tensioner stops rattling if you touch the throttle, but gets worse the more load you put on the alternator/engine. When I had the belt off I checked all the pulleys, air con pulley etc and they all seemed free to spin.
Anyone got any ideas as to what is making the tensioner jump and rattle?
P.S. The site and owners are great - helped me track down and clear airbag light with ease(with the use of Alfadiag)
