I bought a 2010 Ford Ranger Ute, from a Ford dealer. The dealer told me that he replaced the engine, for another as there was a problem with the head gasket on the old engine. I have been driving the Ute, not more then 10000kms over 18months & it looks like the head gasket is cracked on this engine. I know it is a different engine because of the VIN num. do I have any legal rights to go back to Ford dealer & demand they fix / replace??? Thanks GGS
