2005 Toyota Prius Question: What is the bubbly noise coming from my engine when I press gas pedal?

My check engine light went on, I went to Toyota yesterday, they fixed the water valve, put pink cooloant in my car and now when I drive I hear bubbly noise when I press gas pedal, like water swashing. -
Answer 1
take it back in. get a diagnostic run. if they messed up, call them on it. if they won't comply, take it to somebody who will. -
