If you know where it is at then remove the wire and use I believe a 5/8 deep well socket and ratchet and back it out. You have to drain water out of radiator unless you fast at stabbing the new sensor into the hole. If you don't know where the sensor is at then send me a email address and I can send all pertinent information.

Both oil and water tempture not picking heat up then the water tempture goes up and down in secounds car tells me to stop now gone back to not picking heat up

Since you didn't mention the car overheating, it's most likely a wiring problem in the oil pressure/water temp circuit. Just to be safe, check your coolant level and oil level when cold.

Try wiggling the wires on the water temp sensor and oil pressure sensor. Possible the engine computer or wiring running to it is faulty. These sensors may be on on different circuits or interconnected. Hard to tell without a wiring diagram.

Is the check engine light on? If yes, have someone pull the trouble codes and see what you get. Most ECM/PCMs have "hidden" codes that will only show with a scanner.

Are you sure the oil gauge is for temperature and not pressure?

I would check the coolant level too. If you have some air in the system it could cause the water temp issue.

Water tempture goes up and down in secounds then car tells me to stop oil tempture not working

This sounds as though you have a low coolant level. Do seek professional advice, as you are likely to seize the engine.

A ight came on in my dash teling me to check coolent tempture and the tempture gauge was high

So you have an overheating problem. Check the coolant level in the radiator, check for coolant leaks with engine running (fill radiator if necessary), check temperature of upper rad. hose as engine gets hot (this checks for thermostat operation). Could also be a clogged radiator, bad fan clutch, or blown head gasket.

97 chevy malibu 3100 engine, what should the voltage be to the coolant tempture sendor be?

The ECT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature. The coorect way to test this sensor is by OHMs, not voltage. See the chart below.

I ask a question 2 days about why my car was running hot. You said replace the engine tempture sensor. Can't locate it. Someone said it was the oil sensor and tempture sensor are the same, but the one...

The engine temp sensor is near the thermostat toward the front of the engine. Is the car actually running hot? I would measure the actual water temp and be sure before I started just replacing sensors.

My car keeps saying engine coolant hot ac off then the tempture rises and the car over heats and the it says idle enging. Do I need a new engine

Is your check engine light on? You need to get it scanned so you can figure out where to start. It could be a bad thermostat or perhaps a water pump. It may be a faulty coolant temperature sensor. Your best bet is to try and get a code, if your light is on. Have you checked anything yet? Let me know. I am here to help. Thanks for choosing FixYa.

it peobably needs a new coolant temp. sensor thats what the po116 stands for. or it could be loose connector or wire short, but a bad sensor would be a good guess
