I have replaced the water pump, radiator hoses, thermostat, tempature sensor and put all new coolant in and bled the bleeders in my aztec I start my car up and if I go to town not far from home it gets hot really quick and the hot coolant light comes on I ammediately shut my car down when I pop the hood my coolant in resovoir is boiling I dont think its the heater core cause my windows dont fog up upon starting and I have no leakage on passenger side of car. I dont have no leakage anywhere on my engine with coolant

In your replies, please use punctuation, otherwise that huge sentence can be read three or four different ways. What you're describing is typical of a leaking cylinder head gasket. Your mechanic can perform a chemical test at the radiator or reservoir to verify that. The test involves drawing air, while the engine is running, through a glass cylinder with two chambers partially-filled with a special dark blue liquid. If combustion gases are present, the liquid will turn bright yellow.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
