My radiator has a crack on the side so we been putting in water but now it looks like there is some kind oil and gook in the radiator. Can any one try to help me with his problem

You likely have a blown head gasket or cracked block, allowing oil and coolant to mix. Depending on the car, repairs typically run $2,500+.

Is the oil milky looking inside of the radiator? If so its probably a blown head gasket. Pull your oil stick and see if it has milk on it.

If the radiator is cracked and there is nothing in the oil in the engine than it could by trans fluid . Check that .
