195 to 210 degrees is normal.
195---210 degrees.
It prevents the liquid within the engine from freezing or boiling. Coolant does just what the name implies. It keeps the engine cool, meaning it keeps the engine at the correct operating temperature. It also prevents corrosion within the engine and cooling system.
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.
You engine is generating more heat than can be removed by the cooling system. You should pull over, shut your engine and carefully (it will be very hot) remove the radiator cap to check the coolant level in your car. If you know where it is, you can check the coolant reservoir. If you are missing coolant, add enough to bring it to the correct level and monitor it for leaks. Otherwise you may have a problem with the cooling pump.
The correct answer to your question is the coolant sensor is mounted on the radiator, behind the battery. If you have a temperature guage you can simply up plug the sensor connection.
is the coolant temperature sensor giving a correct reading to the computer? Is the fan getting power?
Yes. The engine needs a thermostat to maintain correct operating temperature.
180, degrees. The new vortec motors, after 2000, run at 210.
oil is emulisifieing,drive the car at the speed limit on highway for 25,30 miles at a time, this will get the oil up to correct operating temp.
Check to see if coolant is mixing with engine oil. Run engine to normal operating temperature and remove oil dipstick, let a drop of fluid fall onto a hot part of engine, oil will smoke and coolant will sizzle. If coolant is into engine oil could be a sign of a bad head gasket If fluid level is correct, but still overheating, could be: Thermostat is not opening Water pump not circulating coolant Cooling fan not working
The thermostat controls operating temperature. This occurs at a preset temperature (typically 195 degrees F. or so), which is usually stamped on the thermostat itself. The thermostat should be fully open about 20 degrees F. above the rated temperature. So your operating temperature is about right. If you have doubts, just replace the thermostat with a new one of the correct temp.
If coolant level is correct--sensor may be bad If coolant level is correct--sensor may be bad
