I run dual radiator fans that come on at 180. Before with the 160 degree thermostat it would get up to temperature kinda quick but didn't have a issue at a red light. Any information will be GREATLY appreciated.

Why did you change the thermostat temp?
What temp did the truck run at before?
Is the thermostat the only part you changed?
Can you adjust the temp that your fans come on at?
You need to make sure the system is fully purged before trying anything else.
