My friend has a 1994 Plymouth Voyager with the 3.0 V-6. It blew a hole in a freeze plug and all the coolent came out and he blew a head gasket. We noticed the water in the radiator ,when the engine would crank over, the water would come gushing out. So we changed the head gaskets and now it won't start. We have spark and are getting fuel. but we are still getting water spewing out of the radiator. and sugestens? Thanks.
