now heres a funny one, after having my heater matrix replace about 3 weeks ago, and every thing being very happy, at anything over 3500 revs, and the heat control on the cold setting, i appear to get a squealing system, its like a pressure leak or something, like when you blow up a balloon, and hold the end and let the air out, squeals like a stuck pig. any comments, its defo the heater system, so its a dashboard out.

unplug the heater motor and see if it still does it...there should be no reason to take out the dash....have you bleed the system properly.??

popped up to see adrian at WAD, and he bled the system, for me, what a helpful guy he is, esp to a frettfull 155 owner, and it disappeared, onyl to re appear, after about 5 mins, but he reckons that there is air 'reeding' through the heat control tap, so i might just need to do it a few times.
