The Engine Coolant Temperature in the Engine is higher than it should be.
Check your radiator coolant level - also your radiator may be clogged or thermostat may be stuck.
you could have abad temp sensor
Thermostat may not be opening
Fault temp gauge.
AnswerIs the system overfull?, Is your gauge working?I had the same problem and I had to replace the head gaskets.
The gauge reading has nothing to do with the overheating problem. Misleading and irritating yes, but not involved in causing it.See "Related Questions" below for discussion on replacing the temperature sending unit, and also a comprehensive diagnostic guide for overheating problems.
Replace the thermostate and gasket to start.or your temp gauge
If you are absolutely sure you do not have air trapped in your cooling system then you may have a defective gauge if you are getting heat through your heater. Usually I would say you have a coolant flow problem with either a stuck thermostat or a bad water pump but if you have heat from your heater, then you must have circulating coolant in your system. I would check the gauge or the sensor.
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
heat is the problem. your temp guage is most likely shot and your car is probably vapor locking.
If there is no temperature gauge on a motorcycle, the way to tell if the motorcycle is overheating is by smell or feel. If the bike smells like radiator hot water, it might be overheating. If the legs of the operator start to become so warm that it is uncomfortable to ride, it might be overheating.
The gage fuse Should be located in a compartment behind the driver's side kick panel.
My Altima had that problem and it was the water pump going out. It started with temperature gauge was moving, but then it started leaking and finally the heater stopped being warm at idle.
