Hi, i recently bought the fan, a/c and power steering belts for the is200 and ive been told by the mechanic that the tensioner is going to snap when he tries to remove the a/c belt. Looked into it and its almost 100 quid to buy a new tensioner from Lexus (rip off). Been looking around for one but i just cant seem to get my hands on a new or even used one. Any help would be much apprecited. Thanks in advance:)
