2005 Dodge Ram 1500 4.7 - I am losing water in my radiator but show no signs of leaks and no sign of it leaking into the oil. What could be the cause and where could the water be going? Please help. Thanks,
Head gasket is the most likely cause when losing coolant and no sign of an external leak. You need to have a cylinder pressure test performed to see if the seal is broken -- that's the best method.
