Running temp is 195f so if it reads 212f I think thats OK. make sure the fan is operational above 220f or a/c is on. As long as its not overheating, pushing coolant out to the recovery tank, its OK. there was a computer update (reflash) for these vans. Campaign number 771

I replaced the temp coolant sensor thermostat and radiator and the tep still goes up to 212 to 225 is this normal


It depends on the ambient air temperature and whether or not the AC is being used. Once the thermostat opens the engine coolant temperature can run from 210-230 degrees.So your good.

Radiator fans not working on a 99 dodge Grand Caravan


Hi there:
The engine coolant temperature sensor is a variable resistor with a range of -40 degrees F-265 degrees F (-5 degrees C-129 degrees C).


The engine coolant temperature sensor provides an input voltage to the PCM. As the coolant temperature varies, the sensor resistance changes resulting in a different input voltage to the PCM.


When the engine is cold, the PCM will demand slightly richer air/fuel mixtures and higher idle speeds until normal operating temperatures are reached.


The engine coolant temperature sensor is also utilized for control of the cooling fan.

Fig. 1: Engine coolant temperature sensor location - 3.3L and 3.8L engines



Check this test procedure:

  1. Turn the ignition switch to the OFF position.
  2. Detach the coolant temperature sensor electrical connector.
  3. Using a DVOM set to the ohms scale, connect one lead to terminal A and the other lead to terminal B of the coolant temperature sensor connector.
  1. With the engine at normal operating temperature, approximaterly 200 degrees F (93 degrees C), the ohmmeter should read approximately 700-1000 ohms.
  2. With the engine at room temperature, approximately 70 degrees F (21 degrees C), the ohmmeter should read approximately 7000-13,000 ohms.
  3. If not within specifications, replace the engine coolant temperature sensor.
  4. Test the resistance of the wiring harness between PCM terminal 26 and the sensor wiring harness connector. Also check for continuity between PCM connector terminal 43 and the sensor wiring harness connector. If the resistance measures greater than 1 ohm, repair the wiring harness as necessary.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

What is the normal operating temperature for a 2003 Chevrolet Impala with 3.4L engine? Mine use to be around 185 to 190 degrees on the gauge inside the vehicle. The gauge now can range from 200 to 220...


The range should be in the temp range of your thermostat within in a few degrees, you probably have a 190 degree thermostat. As the outside (ambient) temp rises it's normal for the engine to run a little hotter 200 degrees is safe with coolant, water boils at 212. Your fans should cycle, so it sounds like your temp sensor is faulty. if you haven't flushed your radiator and changed your thermostat lately, now would be a good time to do so. Hope this helps,

2000 Jeep Grand Cherokee with a 4.0L engine... the temperature only rises to about 150 degrees and stops... sometimes lowers a bit even at highway speeds. Normal operating temp is about 210-215 degrees. ...


The thermostat controls the temp of the engine. The temp sensor tells the gauge what temp to display. If the heater is still putting out a lot of heat then it may be a false reading temp gauge. If however the temp is noticibly cooler then replace the thermostat. A stuck open thermostat would also cause the engine to warm up slowly. check for a loose/dirty connection at the plug on the temp sensor.

How do you know if your engine is overheating? the coolant says 210 degrees wut do i do


When your engine is operating normally, the temp on the gauge should be between 190 and 225. The thermostat is set to open at 190 and this controls minimum engine temp. If you sit in traffic the temp will climb to 225 and then the cooling fan will begin to operate to make sure that you don't overheat.You know that water boils at 212 but you have to add 10 degrees for every pound of pressure the rad cap is set to. Also your coolant has antifreeze in it which raises the boiling point even more. A normal overheat condition of your engine would be 300 or more. Does this help?
