Have a coolant pressure test done. Have a compression test done to check for head gasket/cracked head. Check that cooling fans are working. Have a flow test done on the radiator. Have the radiator cap tested. You have an over heating engine.
I dont believe so. Your cooling fan kicks on by a signal from the temperature sensor. The signal goes to the PCM which in turn sends a voltage to activate a relay which powers up the fan. Most fans are 2 speed and when the A/C is used, a second relay kicks the fan into high gear. So, your fan should run at some point after the engine reaches/exceeds operating temperature regardless of if your A/C is on or not. If it does not come on, check your relays first. (you can swap them around to check them) and then your temp. sensor. You can apply direct voltage to the fan itself to check that the fan motor is working. Hope that helps!

There are two devices and one tells the fans when to turn on and is usually located very
close to the thermostat housing. It screws into the block and is
typically about the diameter of a pencil (maybe a touch bigger).
The mechanic should check on the radiator and the radiator fan .Also check the cooling fins of the radiator if the cooling fins are worn out then replace them. You should also check if there is a leak in the radiator and then repair the radiator .The radiator fan ,check it also if the the pulley of the fan is working and if not then replace it or repair it.And the engine oil should be check if the engine oil is dirty or diluted then change oil because of sometimes dirty or diluted oil can cause engine over heat.
go to the radiator and see if there is a big brass type bolt head screwed into it with a plug with 2 cables on it . if it is not there folloe the top radiator hose where it goes to the engine and it should be there. take the plug off the switch and with the ignition turned on join the cables together. the fan should then operate. if it does not check the fuse for it. hope this helps.
it sounds like your radiator fan is not working. once your engine reaches a certan temp. the fan should come on to cool it down. also might be the thermostat is not opening. it is not good for the motor at all to over heat and stall. you could ruin your engine. i would change thermostat first and then run it till it starts getting hot to see if the fan kicks on. if it doesn't, it could be the coolant sensor or the fan itself. good luck.
