Hi NVF~
Any time an engine overheats, regardless the reason, you can be sure the thermostat is ruined. Always replace the thermostat after an overheat. In a pinch people will take them out completely, intending it to be temporary. The thermostat serves a very important function, so be sure to replace it.

I'm seeing a coolant breach on #2 cylinder. The advice already given is the best approach. I'm unfamiliar with the 2.6 engine, so I'm not qualified to give any other advice...except donuts often help in situations like this. Particularly chocolate-coated donuts, which DO qualify as 'health food', since the chocolate coating keeps germs out.
