Some may recall my issue with the water pump, short belt mod, idle pulley and air-con at Christmas.
I thought I'd post some photos of the destroyed idle pulley etc.
I was lucky to have a spare belt and pulley in the car, however, when the air-con pulley broke, I needed a short belt - which I didn't have at the time.
Below: Here are 2 idle pulleys side by side - the top one is a metal & hard plastic style 'assume proparts' version, and the bottom is a metal version - with its box and part number visible.
Below: this is the idle pulley.

Below: as per above.
