Using temperature is not a bad way.  When ours went bad, we checked temperature under the Van, close to the radiator.  With the old partially blocked radiator, the difference was only a few degrees.  With the good radiator the difference was aout 20 degrees.

Does anyone have an easy, reliable way of testing flow
to a vanagon radiator?  Using temperature as an indicator
of radiator performance is not ideal because so many other
factors are involved.
