I drive a 2000 dodge Dakota 4 cylinder it was having radiator problems and kept over heating I never ran it hot, I always pulled over and let it cool off then continued. Today I had to let it cool 4 times. It wouldn't crank after the fourth time. When it did crank it vibrated a lot and would not stay cranked. Is it possible to have slung the piston rod? Give me any incite please.
