Radiator

I just put a quart of oil in my radiator by accident, what should i do.

How did you get a quart in there? If so it was low and if it was low, you need to start and find out why it was low. That might make a difference in how you proceed.

Did you put that oil into an overflow container?

Have you run the car since it happened?
