Question Thermostat bad?

My 2002 Wrangler Sport I-6 has a problem.


The problem is that when I drive for like five minutes, the Temperature Gauge goes up to red and stays there for about 30 seconds or a minute then goes back to normal temp. Also my A/C blows worm air. (not hot).

I just changed thermo, water pump, radiator like two days ago. Flushing system with anti freeze and distilled water- old radiator was rusted out bad- water wetter will help keep it cool- use it in my shelby gt500
