[Sub-Zero]

This morning I thought balls to it I sick of hearing the whining noise so I set about it myself , found the reservoir filter completely blocked solid with crap !!!!!!! So took it out and cleaned with brake cleaner then dried also removed half a pint of fluid to get to max on dipstick !!!!! Hey presto I can hear my engine on tickover makes you wonder if the so called kids in the know are tuned in !!!???? In my case they are most certainly not !!!!!!!!!?
