Has the coolant level been checked? Is the serpentine belt on and the fan in front of the radiator turning?

apacheblood

yes everything there is right and no water leaks

If you have enough coolant and the heater doesn't work, I would guess the water pump has failed.

Should check your heater hoses, if one is hot, the core is plugged up.

Well, a plugged heater core won't cause the engine to overheat.

apacheblood

i will check that but heater only stopped working after truck started getting hot.

Sounds like a water pump to me. I believe the thermostat can be closed with the heater working. So that wouldn't be it.
