ok i think its the powersteering belt that squeaks when im gearing down every time and only when the heater blowers are on, got it tightend a few weeks back as every time i started it, it squeaks,, so does belt need replacing?? thanks
if it happens only with the heaters on itll be the alternator belt.( increase electrical load) and yes as soon as they squeel its worth replacing, there only a few quid
