Unfortunately this didn`t solve the problem,there are 2 tension rollers,top and bottom.You have to rotate the whole unit anti clockwise with a spanner until the 4.5 mm hole at the bottom is lined up with one behind it,insert a pin to immobilise the unit,this loosens the serpentine belt so you can slide it off the pulleys.
Hi folks,new to the group so thanks for letting me join! I'm trying to replace the A/C compressor but don't know how to ease the tension on the fan belt. Any ideas or hacks would be appreciated,this ain`t the weather to be without A/C! Thanks in advance. Simon A.
