Temperature gauge moves a little stays low, engine feels hot

NOTE: The addition of Cooling System Stop Leak Pellets, darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

1. Fill the degas bottle with the correct engine coolant mixture to the degas bottle seam line.

1. Install the pressure relief cap.

1. Remove the retaining clip and the fill tab on the top of the thermostat housing and fill through the thermostat housing until full.

1. Install the fill tab and retaining clip.

1. Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air from the A/C vents in the instrument panel.

1. Start the engine and allow it to idle until engine reaches normal operating temperature. While the engine is idling, feel for hot air from the A/C vents.

1. CAUTION: If the air discharge remains cool and the engine coolant temperature gauge does not move or the low coolant light comes on, the engine coolant level is low in the engine and must be filled. Stop the engine, allow it to cool and fill the cooling system.Run the engine at 3,000 rpm for 10 minutes. Hot air should discharge from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the normal range, and the upper radiator hose should feel hot to the touch.
   • Shut the engine off and allow it to cool.
   • Check the engine for coolant leaks.
   • Check the engine coolant level in the degas bottle and fill to the seam line.

Try disconnecting the sensor. then turn on the ignition switch and see what the guage dose. If it still goes to the top, chances are there is a short in the wiring. If it does nothing, chances are you have a defective sensor.

Yes, the temperature gauge should normally stop in the middle, between the cold and hot points on the gauge. When the engine is cold the thermostat will be closed and will keep recirculating the coolant in the engine block until it warms up sufficiently. Then the temperature of the warm coolant will cause the thermostat to open the channel to the radiator to get rid of excess heat, which should stop the coolant from over heating. So the effect of the thermostat keeps the coolant at a fairly stable temperature. When the coolant runs low, it can't transfer enough heat to the radiator and the coolant and engine then over heats. Watch for radiator leaks under your car after you have been driving it. If the coolant goes low again fairly quickly you could have a leak in a hose or the radiator itself.

If the gauge does not go back to cold when the engine is cold, it could be the gauge on the dash. I am assuming the gas gauge drops with the key off.
You could unplug the temp sensor on the engine to see if it makes any difference.

I would suspect the thermostat first.

Does the engine work up to temperature? Is the radiator coolant hot, even when the temp is showing low?

If so, then try replacing the temperature sensor.

The thermostat may be wearing out. A thermostat controls the engine temperature to keep it at a consistent temperature, The other fan will probably turn on if you turn on your Air Conditioner.

The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.

The fan might not be working because the sensor in the radiator could be bad.
