The temp sensor, is a thermistor resistor supplying restricted voltage to the gauge depending on the heat of the engine, if it has gone faulty (close circuit) the gauge will read hot all the time. You need to find the sensor, generally near the top of the engine, thermostat area and unplug it, the gauge will then not read. Replace the sensor. (WHEN THE ENGINE IS COLD)

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.

You need to know if the sensor is reading the actual engine temp.
Could be a faulty sensor, low on coolant in the radiator, cooling fan problem, and so on.
Could also be a restriction in the exhaust.

My 2000 plymouth neon is overheating, it has a leak near the radiator cap


if you keep going , instead of needing a new radiator , you will need another engine
temp gauges do not read with out water to make them work and if the temp keeps going up after refilling the radiator , it could be a head gasket or cracked head result

The reason it did not read hot, on your temp. gauge, is cause your temp. sensor read's coolant or water temp only, not air, if cooling system is empty, coolant temp. sensor will not read, like an air temp. sensor well, more the likely there could be a coolant leak for cooling system to be empty, also could have damage your cylinder's head's, need to have a block test and cylinder compression test done to fine out if head's are damage.

Car overheating and engine light on


well, driving it 30 minutes after it over heated might have cause serious engine damage, warped head, and other bad engine wear, let the engine cool down park it in a level place and check the fluids, if the water has a milky substance in it then you have a bad problem, if the oil is low then check for leaks, check the transmission fluid for proper fluid level and that could stop the hard shifting.

the smoking could be coming from the fluids that leaked out and when they get hot will start smoking, antifreeze residue will smoke for a short time, it might just need to burn off

There is a cluster of hoses off of the top radiator hose


Sounds like air is in the system, probally because it's overheating. Check the water pump. The impellor is plastic and breaks causing 0 circulation.
