My 2001 1.6 Bravo will start making a rumbling noise (like a diesel) when I switch the air-conditioning on.
I recently had the air-conditioning serviced and the guy said it was not the compressor making the noise as when he turned the compressor clutch manually by hand it didn't make any noise.
Is it possible the Auxilary Belt Tensioner is making the noise when it's under the extra load of driving the air conditioning compressor too?
Could it be the cambelt tensioner?
Is there anything I can do to establish which component is making the noise?
