When my van over heats it starts while its moving and it runs hot to the point tha it shuts off. I recently had the thermostat & radiator replaced but i was told that the radiator housing was cracked and its leaking anti freeze. Could that be the problem & I've let it get worst by continuing to drive it?
How can you tell when its the waterpump or head gasket? on 1993 Mercury Villager

The most accurate way to test for a blown head gasket on a gasoline engine is to test for the presence of carbon monoxide in the cooling system. Snap-On, Matco (part # CO 2000), and Napa sell a tool to check to carry out this test. Another link to a supplier of this tool is http://www.etoolcart.com/combustion-leak-detector-lis75500.aspx. Carbon Monoxide is only present if there is a blown head gasket or cracked cylinder head. http://www.arrowheadradiator.com/head_gasket_or_combustion_leak_test.htm I think the Napa part number 700-1006. http://www.blockchek.com/instructions.htm . Signs of a blown head gasket are coolant loss (frequently have to top up the coolant level of the engine without seeing an obvious leak), experiencing over heating or rough engine running or the presence of white sweet smelling steam from the exhaust. A badly blown head gasket may allow engine coolant and oil to mix.

you most likely have cause internal engine damage from driving it overheated. take it to a shop and have them verify with a leak down test.
