Change the thermostat. Bleed the air out of the radiator and motor. Check for a blown headgasket.

If you find some thick walled rubber hose that fits into the header tank cap hole (~1-2 ft) and stick a bottomless powerade bottle in the top of that (bigger neckhole so fits nicely) you can get a bit more pressure into the system ;D

cant say I'va actually tried it - I just topped up my header tank idling - is the above really necessary? I know some have real trouble with bubbles in their systems...

In my RS I never did it, used to just top it up with it idling as well. Haven't had the same luck with the GTB though and often have the waterfall in the dash sound effects (although thinking about it now I haven't heard that in a few weeks....) and now of a few BG5/BD5's that have the same issue. The tall hose trick helps a wee bit but some of them just never want to give it up. Apparently its caused by oxidation inside the heatercore trapping air bubbles or something to that effect.

But to wrap up this story, I think it helps to have the taller hose but I just use it out of habit now so don't know any different really.
