Either your temperature sensor is unplugged or it has failed and is giving you that reading. (most likely cause...if not, start checking wiring from the sender and make sure any electric cooling fans are plugged in as well.

Since you have already changed everything that you have, I can not think of anything new that might cause your Jeep to overheat. Are you going by the meter in your vehicle or doing separate temperature measurements? I had a defective temperature gauge that caused me to chase my tail till I did separate measurements.

I have a 2000 Grand Jeep Cherokee Laredo (6cyl). It was blowing only cold/luke warm air. I replaced the thermostat. Still blowing the same only now the radiator cap is cold but hoses are hot. ...


It is likely you have air in the system. Park on an incline, take the radiator cap off, start the car, let it warm up until the thermostat opens, fill the radiator until it stops going down. See if that doesn't get you some hot air. If not, try the other steps I have in my post at http://www.fixya.com/cars/r6235876-no_heat_fan_blowing_cold_air . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me.

2000 jeep grand cherokee will not start tempture gage reads hot


This is a safety system built into a Grand cherokee. If it gets hot or loses oil pressure it will shut itself down to prevent engine damage. If it hasn't been started and it reads hot I would say your coolant temperature sensor for the gauge has gone bad and needs to be replaced. They are fairly inexpensive and not to hard to replace.
