Malcolm;
        Well I have given this a bit of thought. All I can think of is
you are not letting the thermostat open when you bleed the system. I
believe the Bentley makes some mention of running at 2000rpm while adding
coolant. This is what happens as I see it. The reservoir is the input to
water pump. As the RPMs increase the output pressure of the pump
increases, pressurizing the system, slightly expanding the rubber hoses,
causing the coolant level to drop. You add coolant and close the lid
while keeping up the RPMs so the system stays pressurized.

Good Luck and Drive Safely
