Have your mechanic do a compression test to look for a blown head gasket.

If the head gasket was blown, between cylinders, the hot fluid would
be gushing out the top of the radiator with the cap off. Aside the
van engine would run erratically.

As simple as worn out rad cap. If a mechanic does not do a pressure
test, dye test, observe tail pipe, taste tail pipe soot, what is he
doing to trouble-shoot. Old jalopies should be retired.
