    Hello, my prius started to lose engine coolant and i went to a car shop and they diagnosed that it is leaking at the catalytic, and i got a quote for almost $3,000 for catalytic replacement. I searched the internet and found out about coolant bypass as a fix is it a safe alternative long term? And is there a mechanic here in the bay area that you can recommend that can do a bypass? Thanks!
