Sounds like your thermostat is done for. The water in the hoses is probably heating up from being close to the hot engine. This continued to happen to me after i replaced the thermostat twice thinking maybe i had bought a bad thermostat turns out it was the heater core. Both the front and back were pluged.

What is the layout for radiator hoses on a 1990 Chevy Astro van?
one large hose from bottom of radiator to side of water pump. other large hose from thermostat housing to top of radiator. one heater hose from water pump to heater core, I think this one has a Y in it if there is a rear heater other heater hose from heater core to somewhere on top the engine. If there is a rear heater, its return hose goes to a fitting on the radiator.
