[Mgs] Flushing the cooling system?

[Paul Hunt]

Simply running an MGB through 2 or 3 heat-cool cycles with the heater tap open
for at least part of the time (if it is summer) should be all that is required
to eliminate all the air, I've never had to do any more than that on any car I
have owned, and have drained and refilled both the 4-cylinder and V8 several
times.

"I bet the auto makers are just thrilled about the overflow bottle
requirement. They really needed something to fill the vast void under the hood
of the modern car ;-)"

There's not that much space in modern cars (American trucks excluded) with
their low frontal area which is for aerodynamic and pedestrian safety reasons.
The MGB had to go with the remote expansion tank when the radiator moved
forwards for the V8 and 77 and on 4-cylinder as there was no longer enough
room for the header tank and particularly the radiator cap under even that
bonnet.
