Thanks, of course you hope for the best, least expensive repair. I will reinstall the water pump and thermostat and then pressure test anyway. It'll cost me nothing but time. Really can't complain nearly 200k miles 15 yo and I haven't put much into this van.
Doing a head gasket myself isn't something I will enjoy doing but for that kind of money it makes sense rather than buying some elses headache.
