    Did the dealer possibly give a "hotter" thermostat than what you had in originally?

I changed thermostat, radiator, water pump, hose, engine cooling temperature sensor, radiator cap and I'm still overheating. 2004 Chrysler town and country

Check the heater cores. There are usually 2 in a T&C. Also check the pipes running to the rear heater core. I recently had to have mine repaired because they were leaking!

I have a 2002 mitsubishi montero sport and we changed the thermostat, did a radiator flush and change radiator cap and the needle passes to mid point (normal) it hasnt overheated but it doesnt stay in...

Where do you live?
This has been a hot summer, bit hotter than usual due to the solar flares going on...
as long as the pointer stays within normal operating range, you must not worry... especially since you changed the thermostat and did a flush, did you make sure you got the right temperature range thermostat installed, rarely but few times that seems to be the problem, hotter thermostat gets installed by mistake.

My 99 ford f150 pu can sit for 30 to 40 min warming up to operating temp then I leave for work and go aproximatley 15 to 20 miles and loose heater then the engine over heats. After a few min it boils over...

Change the thermostat. The thermostat might be opening too late to circulate. From doing so the coolant is just sitting there getting hotter and hotter which would cause overheating until the stuck thermostat decides to open. I would bring the car to a safe temperature and feel the radiator hoses if one is hot and the other isn't? You have a thermostat problem. Easy fix and cheap. I wouldn't run the vehicle too long until you fix it.

Truck is overheating replaced the thermostat still getting hot more when i run the ac

Most likely a bad water pump. Does it run hotter than usual at higher speeds like on a freeway/expressway. Check the fins in the radiator to make sure they're not clogged and restricting the air flow. Use a hose from the engine side and spray the water towards the front as that's the easiest way to remove the debris/bugs/dirt/pollen that may be adding to the problem.

My truck is getting hot ,even after I changed the thermostat

Your thermostat could be bad, getting stuck. I had that happen. While driving down the road I noticed the guage went way over to the hot side then went back. I changed it and all is well. It will run hot if there is something blocking the air flow through your radiator. Good clean oil up to the fill line will help your engine run cooler. If you havent changed your oil and filter lately, the oil filter may be clogged (full) and the oil is bypassing it. This will leave gunk and metal parts in the oil that make the oil hotter than it should be. Make sure your coolant level is topped off and you have antifreeze in it. The proper mixture of antifreeze helps keep an engine cool. If there is too much grease and oil buildup on the outside of your engine it will run hotter because the air flow cannot reach the metal and cool it off. Is your radiator clogged. Some people, if they have a leak in the radiator will use stuff to seal it from the inside. These additives can clog the radiator. 
Are you sure you have the right thermostat ?
