you could have abad temp sensor
The engine is overheating. The check engine light is not on because you have no problem with the emissions system which this light monitors.
Check actual engine temperature with a thermometer--if in acceptable range temperature sensor or gauge may be defective
check the temperature control sensor....
The solution to engine overheating depends on the underlying cause. Some common causes of engine overheating are low coolant levels a faulty thermostat a broken water pump or a clogged radiator. To determine the cause of the engine overheating you should first check the temperature gauge on the dashboard. If the temperature is rising then the problem is most likely related to the cooling system. To resolve the issue you can take the following steps: Check the coolant reservoir and refill it if necessary. Check the thermostat and replace it if it is faulty. Check the water pump and replace it if it is broken. Check the radiator for any obstructions or clogs and clean them out.If the cooling system is in good working condition and the engine is still overheating then there may be other issues such as a worn out head gasket a problem with the fuel injectors or a worn out timing belt. In such cases it is best to take the car to a mechanic for further diagnosis and repair.
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.
Yes. However, I would check the other components first. Check the fan relay and temperature sensor, and if that is not the problem then check the fan itself. Also, it could be a leaky head gasket, which causes air to be pumped into the cooling system, thus overheating it. Yes, but.... there are several things that can cause overheating on a water cooled vehicle. The water pump, not enough water or coolant in the system or not the proper mix of water and coolant. The fan could be weak or failing, there could be a problem with a hose... sometimes a hose will weaken and be sucked closed by the engine and you would not know because it only does so under pressure. You may have the wrong temperature thermostat installed. Check all of these points to be sure.
Check the thermostat first. I had an intermittent overheating problem on my 02 for almost a year, changed the thermostat and it never happened again. If that doesn't work, secondly I would check the water pump.
Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat
Check to make sure you have the correct mixture of anti-freeze and water because anti-freeze also helps with overheating too. If you still have a problem check your thermostat. It could be stuck closed and may not be opening.
Overheating is due to, well, the coolant in the cooling system getting too hot. In a normally operating engine, this should never be a problem. First, check that the coolant level is correct. If it is correct, I would suspect a problem with the thermostat. When the engine is cold, the thermostat closes off coolant flow through the engine until the coolant reaches a pre-determined temperature. When that temperature is reached, the thermostat opens to allow the coolant to circulate at that exact temperature. Thermostats are known for failing and either not opening or not opening enough at that pre-determined temperature. This causes coolant to get trapped too long in the engine coolant chambers, heating it beyond limits, causing the engine temperature to increase and possibly overheat. If my Maxima was overheating, I would check the coolant levels and then possibly replace the thermostat. It usually is no more complicated than that.
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.
Check the operating temperature with a thermometer - if within normal limits replace the temperature sensor if overheating write back - many things to check
