I recently had my oil changed and radiator flushed. There was some dripping fluid, on my driveway that appeared to be antifreeze a few times after the engine was flushed. When I accelerate, I hear the sound of running water coming from inside the dashboard. It's very distinct. The heater core has been replaced twice over the last two years (every December!). Help please.

Sounds like they didn't bleed the system after putting in fresh coolant. There's still some air in the system.

Yes, there is air stuck in the heater core, it should go away after a few miles, or I have heard of people raising the rear of the truck up while running to help purge the air out of the core.
