copy Bill's swirl tank and mount in the highest spot in the engine bay.
-close off cap on radiator
-overflow cap is now on swirl tank
-plumb rad and engine to swirl tank
-attach over-flow line to swirl tank
-air is vented when you top up the system (open the cap)
if you can find a copy of issue 5 of RACE magazine, you'll see how the porsche 962 has a swirl tank for the cooling system (radiators each side of the car) mounted way up high above the engine.
cheers,
Charles
