My Pickup truck is over heating, I changed the thermostat and it looks like the termostat is not opening all the time. I dont know if it because I replace the prestone with water????

do a search on google.com, this group, and check out all the possibilities.
Like... bad fan, thermostat, filmed/clogged radiator, and air pocket in engine.
Check the head gasket. If the engine has overheated, it's a good bet the haed is warped and needs to be resurfaced.
An engine will overheat for two reasons; 1) poor coolant circulation --either the thermostate is stuck or the radiator is stopped up. 2 ) You are loosing coolant due to a leak.
Remove the theromostat and see if the car still overheats. If so then you have a leak somewhere. If you have a warped head or blowned head gasket, there will be white smoke out the tailpipe.
Lately I have seen a lot of cars that indicate overheating but do not overheat. That is because the temperature sensor is defective. If after overheating your car still has a proper coolant level that could be the cause or a defective thermostat.
