Why is my temperature gauge reading hot but not overheating?

Why is my temperature gauge reading hot but not overheating?

As a general rule, you can say your car is running hot but not overheating because of a problem with the cooling system. Cooling system problems include a failing water pump, low coolant level, old coolant that is no longer effective, a faulty engine coolant thermostat or a faulty auxiliary fan.

What would cause the temperature gauge to go cold to hot?

What would cause the temperature gauge to go cold to hot When driving the car the temperature gage goes to normal temp then to cold then back to normal or hot an this continues happens when you are driving it My car has 1300000 miles. My car has an automatic transmission.

How does the temp gauge on a car work?

The temperature gauge utilizes a sensor, located near or in the thermostat housing, to send an electrical signal through the vehicle’s internal computer corresponding to the specific coolant temperature, giving the gauge on your dashboard an accurate reading of the temperature.

What causes the temp gauge to peg Hot?

When my car is running, the temp gauge goes and pegs hot, even if the car is cold. I dont know if its a coincidence that I just changed my plugs or what, but Id like the gauge to read proper. What would cause it to peg hot??

What to do if your temp gauge goes to zero?

Turn the ignition on, but don’t start the car. Give what you say above, the temp gauge should read half. Now unplug the sensor. If you have a bad sensor, the gauge will go to zero. the gauge will stay the same. Well the FSM points just like you said to the passenger upper rear for this sensor.

How can I tell if my light gauge is hot?

Check the gauge if the needle moves toward “Hot”, the wire from the gauge to the sending unit has an open or bad connection. If it does not move, connect a test light by grounding one end to a good known ground and the other end to positive side of the gauge (typically a pink wire).

Why is the temp on my car so high?

If you notice your temperature gauge needle moving irregularly or communicating an inaccurate temperature, unreasonable to current conditions or without symptoms, it may be defective. The cause may be related to bad wiring, a bad connection, or a problem with the coolant temperature switch, and even a problem with the vehicle’s internal computer.
