Re: Coolant

Joe,

To get the coolant to return whilst the motor cools you need
the correct kind of cap and no small air leaks or soft hoses
in the system.   TR3/early4 factory radiators need a certain
cap for the deep filler neck.  The water pump seems OK
with a 7-8 pound cap ( fitting a second spring to a 4 LB cap
works)

As far as  the temp. ;ducting the air flow is the most important thing.
On a 3A/B removing the stock piece behind the grill uncovers a large
part of the radiator
