    Checked the coolant, oil and sensor, everything looks okay.

  • crubis Apr 14, 2009

    Thermostat was replaced two years ago, radiator one year ago, the problem started two days ago. Is it possible that temperature sensor is getting bad?

  • crubis Apr 14, 2009


    I'm at work, so I didn't get to pulling and disconnecting cables yet.

    I have no problem with horse power, but I think in the last four or so weeks my fan is working a little bit longer after I stop and turn off engine then before, but I could be wrong.

  • astrid prieto May 11, 2010

    Hmmm, thermostat ok or removed or opening incorrect?

  • astrid prieto May 11, 2010

    Bit fast checking that. How is the fan doing?

    Intermittent electrical or still belt?

    How is the horse power? same?

  • astrid prieto May 11, 2010

    check oil and coolant. Anything grey, levels ok.

    connectors on gauge still seated properly.

    Element still ok on engine

At first my 1997 Oldsmobile Cutlass Supreme (only has 59,000 miles) after driving for a while the temperature gauge would start to rise when idling but when I started driving the temperature would go back...


This sounds more like the thermostat is not opening as it should, instead of an ECM problem.

With the indications you state - goes down when heater activated - goes down when moving, that is what I would have checked first, not the cooling fan!

connector may be loose at the temperature sensor. connector should be snug on the sensor. If necessary, bend the terminals carefully to make firm contact. If this does not solve the problem, you may want to replace the sensor. Please let me know if you have questions, and thanks for using FixYa.

Teampreature gauge not working


Sounds like you have installed a 'over-temperature switch' type sender unit- this type of sensor is only meant to control an over-temperature alarm indicator lamp that is either 'on' or 'off'.

The temperature gauge requires a 'variable resistance type' temperarure sensor to control the meter deflection.
When cold the temperature sensor is of high resistance, hence less meter deflection;
when hot temperature sensor is of low resistance, hence more meter deflection.

You need to procure a matching sensor to suit the type of gauge installed.

Is it possible you have connected to the temperature wrong temperature sensor? - most vehicles are fitted with both a gauge type (variable resistance) sensor to drive the temperature gauge, as well as a switch type (on or off) sensor to drive the overtemp indicator light.

Temperature Gauge Always On Cold


As long as your gauge is still moving up, there's no real problem. You have heat coming from the heater. It's only a problem if it's getting too hot. What's going on is that you don't let the vehicle run long enough, and it's so cold outside that the engine stays cold. It raises in temp when your stopped because there's no airflow through the radiator. The thermostat just heats up the engine block, and won't change the reading on the gauge. When this goes bad your car will overheat in just a few miles.

Erratic Dash Temperature Gauge Readings


assuming there is nothing wrong with the water pump, it may be the sending unit is going bad, or it could also be the thermostat going out. it is more likely that the t-stat is the problem as it is the erratic behaviour of the guage inside that is the concern.
