Boiling at 220 degrees
Coolant boiling at 220 degrees, it runs at 190-205normally. But when I turn the car off and the temp rises to 220-225. That is when I hear boiling. Is there any fixes for this before I take my car in? Only mod is high flow cats, no tune.

I would think a leak in the system has occurred, and check for that or a weak cap.

If it truly is afterboil, a friend just had a problem with his car. Check the cap. Afterboil means the system isn't getting up to proper pressure.

Check for leaks in the hoses as well. |

as a general FYI, a 15psi system will raise the boiling temp to just about 247*F (when working correctly).
