Ok, It might be a headleak BUT I�d try not to worry �bout that right away !
You wrote that you�d just replaced the waterpump, what�s the reason for
doing so, was the Vanagon coughing water before that ??
If not the problem you have is most likely to be caused by air !
There are these looooong hoses and pipes, radiator away from the engine and
big chance that you have an airbubble somewhere !
Additional heater under the back seat ?
Another place to get air !
I haven�t got the Haynes so I don�t know how the procedure is described but
according to the Haynes manual you raise the front at least 15 " over the
rear , full heat on every heater and bleed the radiator - for a long time,
not just a few drops , and the best is if the engine is really hot when you
start ( don�t get burnt !)
I�ve tried this and it worked for me - even after changing to the Volvo
engine.....
And if this doesn�t help, look for cracks in the expansion container or
leaks from the lid !
BTW - did you replace the thermostat ?
Many times remaining air in the system is caused by the fact that there are
airbubbles under the thermostat, preventing water to get up and heat - open
the thermostat !
You check this by squeezing or feeling the hoses leading to the thermostat
housing once the engine is hot , you should be able to sesnce the heat or at
least water running inside .
There might also be a bleeding valve on top of the housing........

Start with this and if it doesn�t help we�ll go on from there...

Good Luck
