I have a 2000 Dodge Dakota. I have engine oil in the radiator. There is no coolant in oil, no transmission fluid in radiator, no coolant in auto transmission reservoir. JUST engine oil in radiator. What could be causing this???

 

Blown head gasket,do in pairs for fix,left & right.Just a thought........................................... ................

 

are you sure it's motor oil and not transmission fluid? Very possible the tanks cracked between the trans cooler and radiator That's what wiped out my transmission, turned the trans fluid to milk.

 

Nope, definitely oil in radiator.

 

What engine are we talking about?

 

Can still be a blown head gasket or a cracked head or block. coolant wont always be in oil pan. It depends on which passages where the block meets the head are compromised.
