Car: 1985 MKII (duh) with PS. The compressor for the AC is beginning to fail, the screach at low rpm is horrible. I disconnected it electrically by the connector and its just as bad. The belt I need to change would be the crank/compressor, then compressor/alt. Is it possible to pull the compressor and use a longer belt like Crank/PS/ALT? and tighten with the ALT adj?
