After you've drriven the vehicle for a while, stop, turn off the ignition and open the hood. Do you hear water boiling in the radiator or is the coolant recovery bottle overflowing[you'll see plenty of steam this time of year]. If you don't see any signs of overheating then it's not a problem.

Fuel gage not working


Could be the sending unit in the tank, or the gauge on the dash. A mechanic would check the signal from the sending unit at the tank.

Where is it located and what does the oil sending unit do?


Your oil sending unit is located somewhre on the engine. It will be round and about 1 to 1.5 inch across. It will have a wire attached to the top of it. I dont know the specific location on your particular car.

What does it do? It is a diaphram operated device that sends a signal to your oil gage or warning light. The engine side is exposed to oil pressure in the engine. The oil presses against the diaphram. The diaphram is attached to a variable resistor device that operates the gage. Low pressure on the diaphram -= low signal to the gage; Hight pressure on the diaphram = high signal to the gage.

Where is the temperature sensor for the temperature gage


Engine Temperature Sensor Operation:00116_engine_temp_sensor.jpgThis sensor monitors the temperature of the engine and sends that information to the engine control computer to regulate the amount of fuel needed - more if engine is cold and less if it's hot. The signal generated can also be sent to the temperature gauge as a visual indicator of overheating and imminent danger

I checked with autozone.com and their site says that the engine temperature sensor is not used on both engine sizes available for this vehicle.

The Coolant Temperature Sensor is used though. So maybe it has a dual purpose on your vehicle.

Coolant Temperature Sensor Operation:00113_coolant_temp_sensor.jpgThis sensor monitors the temperature of the engine and sends that information to the engine control computer to regulate the amount of fuel needed. More fuel is needed if the engine is cold; less if it's hot. If the temperature is extreme, the signal will be sent to the temperature gauge as a visual indicator of overheating and imminent danger.

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.

Can hear gurgling water in heater core when I rev motor. heats good then goes cold and the temperature gage goes staight to hot. Cut off engine and restart and the temp is fine. new water pump, heater core...


you didn't say that you replaced the thermostat....sounds as if it is sticking. You can always remove it and put the housing and such back together (w/o the thermostat), you won't have heat; but this will tell you if the thermostat is the problem or not. Also there is a temp sending unit....usually around the thermostat housing - indicated with a elec. plug running to it. It would be a good idea to remove it from the housing and clean/replace it, the sending unit can also make the engine run terribly if not working properly, and decrease gas mileage significantly.

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Temp gauge off charts


Are you mistaking the engine temp sensor for the engine temp sending unit? The temp sensor is for the fuel injection system and the temp sending unit is for the gauge. If you asked for a sensor thats what they sold you. You need to ask for a sending unit.
