Without opening the bleeders and the engine cold start the van. Rev the
engine this drives the coolant to the radiator top off the coolant and rev
the engine a little more to see if the level drops more add more coolant if
needed. Put the pessure cap on before you lower the engine RPM and you are
DONE
