Check for a leak in your radiator or water lines. Most likely this will be where the problem is but if you don't find one there look for water leakage somewhere on the block. If you have a water leak on the block depending on where it is this is a serious problem and you will most likely see a relatively oil free area with some rust discoloration.

Temperature sensor on 2007 Malibu Maxx LT location


Lumina V6, 2000 model after starting 5 to 6 mins temp gauge goes up slowly. Cooling fan is on. Coolant ok. If stopped the car and started again gauge needle comes down quickly to normal and then runs normal at any speed. It happens only first starting. I am suspecting temperature sender malfunction. Could not see the temp switch position to check its connection.On earlier models it is located directly under the thermostat. But if its bad it should throw a code making your check engine light come on. Sounds more like a thermostat problem. Even if its a new one they can fail.

What causes a car to overheat?


How do you know it's over heating ? Are you going by just the temperature gauge in the instrument ? or is the engine making strange sounds ! Sometimes the temp. gauges go bad or the coolant temp. sensor , making you think it's over heating when in fact it's really not !

2003 volkswagen golf engine temperature gauge and engine light on


If the temp gauge reading is high when the engine is cold it will be a short to the sender unit or a faulty sender unit ( as opposed to a temperature sensor unit). Have the fault codes read to find out what put the engine light on ( overheat)

Trouble codes p0118 temperature po118


code p0118 refers to engine coolant temperature (ETC) sensor ---circuit malfunction===causes---coolant thermostat---wiring open circuit/short to positive---wiring short to ground---ground wire defective---ECT sensor.. The temp gauge works off a temperature sender unit separate to the coolant sensor and if it is reading 100 then it indicates an overheat situation in the engine . Probably why the engine light is coming on. As the thermostat is in the list of causes I would replace it as a precaution. The coolant sensor is what tells the CPU to turn on the electric fans to cool the radiator

Temperature gauge not working


Hi there,
My name is Steve. I can tell you that the barometric pressure sensor can, in no way, effect the temperature gauge operation. The gauge gets a signal from the engine computer which, in turn, gets a reading from the coolant temperature sensor. Your first step should be to have the check engine light diagnosed properly...starting with checking for codes. You likely have a code(s) relating to engine temperature or the temperature sensor circuit. Most common problems are erratic sensor operation and corrosion or oil contamination in the coolant temperature sensor connector. You will be time and money ahead by having a professional diagnose the problem correctly before deciding to buy any parts.

Temperature gauge goes from zero to overheat


Your coolant temperature sensor is bad,it's screwed into engine by thermostat housing,easy to remove,just disconnect electrical connector and get wrench and remove.

The check enging light comes on then goes off. I foud out the code po118 engine coolant temp circut high input. is it the coolant temp sensor. if so how do I replace it. It is on a 2004 jetta tdi


According to Autozone.com:

Because ECT (engine coolant temperature) sensor procedures vary depending upon their location, first locate the part. You may need to partially drain the engine coolant to prevent coolant spillage.
  • Disconnect the negative battery cable.
  • Unplug the ECT.
  • Then, unscrew it.
  • Reverse the removal procedures to install the new part.
  • Connect the negative battery cable to the battery.

The coolant temperature gauge sensor is a temperature-variable resistor, or thermistor. As coolant temperature increases, the resistance of the sensor decreases or decreases, depending on the type of sensor.
A1 and A2 platforms use a different type of circuit that A3 vehicles. On A1 and A2 vehicles, the circuit is a "resistance to ground" type. A3 vehicles use a "variable voltage" type, where a voltage is supplied to the sensor. Because of the circuitry design on A3 vehicles, testing of the coolant temperature gauge is limited.
The engine coolant temperature gauge uses a heat sensitive sending unit to transmit an electrical signal to the gauge. The sending unit is a heat sensitive variable resistor that is located on or near to the cylinder head and threads into an engine coolant passage. The sensors are a Negative Temperature Coefficient (NTC) type. As the temperature increases, the electrical resistance of the sensor decreases. As the coolant temperature changes, so does the resistance of the sensor. The gauge is calibrated within the operating range of the sensor and interprets the resistance value to display the coolant temperature.
Beginning with model year 1994, the engine coolant gauge and the Engine Control Module (ECM) temperature sensors were combined into one sensor with 4 terminals. The basic operation remains the same in that their resistance decreases as the coolant temperature increases, however the actual resistance values of the 2 sensor circuits are different. The electrical connector of the 4-wire terminal sensor ( 1 and 2 ) is keyed to prevent improper connection of the sensor's electrical circuit.

Where's the heat sensor on the engine located. Couldn't locate it


Hey debo9593, does your Nissan have a temp gauge on the dash(some vehicles just have a light that goes on when the engine overheats). If u do have a gauge, what is it reading (normal range, or an actual temperature). I'm asking all this because it sounds like your thermostat may be stuck open, which would not allow the truck to reach normal operating temperature, and also result in poor heat in the cab. It could be other things if the thermostat is ok, such as a heater core plugged up w/ rust and corrosion. so, let me know about engine temp, and we can follow up from there.I
