2004 Venture Van Overheating and shutting down the engine, due to overheating

Hello, continuing to drive the vehicle and allowing the overheating to continue to occur can only do bad things to the engine. There's no way to know what is happening until testing is performed - but please stop driving! You're going to cause more and more damage as overheating is allowed to continue to occur. Coolant bubbling back into the coolant reservoir can be a sign of an air pocket in the system, or could be evidence of an internal engine coolant leak. Hands on testing is needed. Thermostat? Water pump? Cooling fan? Cylinder head breached? All totally unknown and nothing to guess at. www.repairpal.com/repair-shops
