I have a 97 Mustang GT, engine swapped w a 2011 crown vic police, 105k miles (Roughly).

I've replaced the waterpump, thermostat, radiator fan, coolant, tried to purge the system (Not too sure how exactly but I let it run w the cap off until thermostat opened up and bubbles came up)..

I've even installed a new gauge, I was on the highway hottest it read was 235 degrees w AC on, stopped in traffic, 107 degree weather. I know this is bad temps for this 4.6.

My temps usually run 210 - 224 w AC on in traffic, this was the only time it reached 235..

I'm not sure if I did any damage (I hope not) but it's not running any differently.

Any help is GREATLY APPRECIATED!!!

Thank you.

You're running hot but that is to be expected when running AC in traffic in our Texas heat (it hit 108 here today).
