Where is the temparture sensor on a 97 chevy blazer 4.3


There are two temperature sensors on the engine. One is designed to send information to your engine control module. The other information to your gauge in the vehicle. It would be a good idea to check your coolant level as on this model they are noted for leaking coolant from their intake gaskets. Also when engine has been driven for a while see if the upper radiator hose is hot to the touch. You may have a thermostat that is stuck open causing your condition.

2000 Pontiac Sunfire GT 2.4L Low coolant light on, even with coolant reservoir full, car is overheating.


I think the first thing I would do is take the thermostat out and run the engine without it.
If the engine stops running hot, try a 180 degree instead of the 195.
As for the low coolant light, can you unplug the sensor and make the light go off ?

I have a 2006 cadillac dts and on a couple times i've noticecd that when using the defrost in stop and go traffic that the temparture gets extremely hot. last the there was a message stating that the...


What your problem is indicating is that for some reason, insufficient coolant is being circulated through the engine. There could be many causes for this, the most common listed below:
  1. Low coolant level
  2. Bad thermostat preventing additional coolant from reservoir from entering the system
  3. Leaking radiator hose
  4. Leaking radiator
  5. Bad water pump - a symptom of a bad water pump is the inability to adequately circulate coolant throughout the engine. This is especially true at low speeds or at a stop when the water pump turns at it's slowest.
I hope you find that I've adequately answered your question.

CHECK COOLANT OVER FLOW RESERVOIR MAKE SURE IT HAS COOLANT IF YES.YOU COULD HAVE A FAULTY COOLANT LEVEL SENSOR IN THE COOLANT OVERFLOW RESERVOIR. CHECK TO MAKE SURE ELECTRICAL CONNECTOR STILL INTACT.LIGHTLY TAP WITH THE HEAD OF A SCREW DRIVER BELOW COOLANT LOW LEVEL SENSOR BOTTOM OF COOLANT RESERVOIR.IF LOW COOLANT LIGHT GOES OUT COOLANT SENSOR PROBABLY STUCK IF LIGHT STAYS ON COOLANT LOW LEVEL SENSOR BAD.

Need to replace coolant sensor were is it at my coolant light stays on I reset it but it keeps coming back on so I think it is the sensor.


Follow the top radiator hose to where it meets the engine, that will be the thermostat housing, it will be on that or nearby.
