I have changed thermostat (2) coolant full, replaced fan clutch, just keeps one temperature all the time, no idiot lights on, never gets hot. Is their a temperature sensor on this engine for that? I have 4.6 Ltr.

Hi:
Do you mean the engine never warms up or the heater?

Hi:
It sounds like the blend door isn't opening far enough. It is located near the heater core. Air from the cowl comes in and the door determines how much air can go past the heater core to warm the vehicle.

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