Damn good idea!  It can expose a myriad of sins.  15 psi is called for.  I
would check it cold AND after it has reached operating temperature.  I have
seen hydronic systems test out good cold then, once up to operating
temperature, it is time to get out the umbrellas.  Although, Vanagons
sometimes seem to show their weaknesses more after they cool down.
