Engine is not overheating. Upon starting, temp gauge needle gets buried hot, and doesn't move. I have already replaced the ECT (engine coolant temp) sending unit (for the gauge), with no change.

SOURCE: Temperature needle stays on the hot and doesnt move even when the car is cold?

YOur guage is faulty. Your will need to replace your guage if it stays in the hot position even when your car is off and your key is out of the ignition. If it only rises to hot when you turn the key to the run position, you have a wire between your guage and your temp sending unit that has been gounded out. Usually this happens when a person opens their hood to add oil or perform some minor maintenance on the engine and inadvertantly bumps the sensor or switch or wiring. This causes about 65% of these minor issues people incur, but if it does stay all the way up with your key out of the ignition switch, then you will need to replace your temp guage.

The temperature gauge goes up when car starts to HOT like its out of calibration. the engine is not overheating


check that the wire to the temp sender unit has not fallen off and is shorting out on the head/block. The power comes from the ignition switch through the gauge down to the sender unit and because the sender is a temperature controlled resistance unit the voltage is very low and so the gauge reads cold . as the temperature heats up , the resistance is decreased and so the voltage is increased though the gauge and the needle reads higher.. Hench if the gauge goes directly to hot on start up the wire is shorting out or the sender unit is faulty.

Why doesn't my car get up to operating temperature?


Well the first question would be what does the temp gauge on the dash show after you have run the engine for 5 or 10 min ?
If the gauge is in the middle of the temp range the engine is getting hot and either the heater core is stopped up or you have a problem with the blend door under the dash.
If the temp gauge is staying around the cold mark the thermostat is not closing to warm up the engine.
I am assuming the radiator is full of coolant.

Heater is not getting hot and the temperature needle isn't working


First I would have said your thermostat is stuck open. But if the engine is overheating and the gauge reads cold the cooling system is probably empty. Or there may be alot of air pockets in the cooling system instead of all liquid coolant.
If the system was full and the water pump failed the heater might not work but the gauge would read hot.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...


Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

Temperature gauge fluctuates and the heater blows cold air


Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.

Temperature gauge goes up and oil light goes on


It's overheating.  check thermostat and water pump, also radiator coolant levels.  once you get it running at normal temp again take it to the shop and have them do a chemical test to see if the head gasket was damaged or the block was warped or cracked as this usually happens when your car overheats.
