The heater core burst at highway speeds with high pressure which could have scalded my son sitting on the passenger seat. At this time there were no parts at the dealership so they bypassed the heater core so the van could be driven. I have heard from the dealership and other 2000 chevy Venture owners that this happens on all of these vehicles.
