When car is at operating temperature and during hard acceleration, coolant comes out of coolant reservoir. What causes this?

Hello, I am Danny.

It sounds like your radiator cap needs to be replaced. After time they wear out and the spring will not hold pressure. Replace with the same P.S.I. Rating. Hope this helps and feel free to ask any other questions if needed. Thanks for using 2CarPros.
