If its an 89, it will be on the drivers side, closes to the firewall, of the cylinder head
Only the High Output ( 92-96) is on the thermostat.

Coolant Temperature Sensor
Low coolant would be because the coolant is low or the sensor has failed, Check engine light would be because the computer has detected a problem and set a code.
Make sure you have engine coolant. If the engine isn't getting enough coolant, it will overheat, stall and possibly destroy the engine. One symptom is that no coolant is circulated into the heater. Also check the crank sensor, but check coolant first...then the crank sensor.
A coolant sensor could be a liquid level sensor and the other is a temp sensor OR The coolant is different temperatures at different places inside the engine and way way cooler when it comes out of the radiator so where the two sensors are mounted can cause difference's. OR they are two different pieces and calibration will not be identical and they will produce slightly different readings.
(based on a 96 civic LX) I believe the engine coolant temperature sensor is located on the side of the engine (opposite of the camshaft). If you need more details, I would recommend you to download the service manual on www.manualnguide.com
That would be the engine coolant temp sensor for the dash gauge only. The sensor near the thermostat housing is the engine temp sensor for the ECM.
One sensor would be for your engine temperature gauge and the other sensor for the OBD II engine management system
Coolant level would be a sensor going into the fill cannister on the left side of the engine bay. Temperature would be done with the sensor just below the EGR valve on the engine just above the transmission bellhousing. Tiny little wire going into a single plug sensor.
Bad coolant sensor or faulty wiring to the sensor.
50 50 coolant is what i use- would suggest no more han a 60 40 mix.
The engine coolant temp sensor can do that. If you have a check engine light on, have the codes read.
The engine coolant temp (ECT) sensor on that 97 S10 2.2L would be found close to the thermostat.
more likely to be a faulty coolant sensor or the thermostat is faulty and staying open
If it is a temperature sensor, it is usually located on the top of the engine near the thermostat. If it is a "low coolant sensor", then it is located in the radiator (it will be the only item in the radiator that has a electric wire going to it) Either way, you would drain the coolant enough to be below the sensor, and then remove it and replace it with a new one. They are usually under $10-$20
Assuming this is a 4.3L engine the ect (engine coolant temp sensor) would be located next to the thermostat housing.
Yes, a faulty coolant temp sensor can do that.
It would fit, but it would not run properly. The cam and crank sensor tone rings inside the engine are different.
In the engine compartment, on the left side of the engine is the coolant reservoir. In the coolant reservoir, there is a sensor at the bottom of the reservoir. This sensor is supposed to let you know when you are low on coolant, but can also become defective, and give you a "false-positive" reading. The only way to know this is to check your coolant when the low coolant light comes on. If there is a significant decrease in coolant, you may have a problem in the cooling system , but if you don't, chances are the sensor isn't working. If the sensor is the problem, you can unplug it from the coolant reservoir, by unscrewing the two screws holding the reservoir to the car's inside firewall, then tilting the back of the coolant reservoir forward until you see wiring coming from the bottom of the reservoir, which is the plug for the low coolant sensor. Unplug the sensor, and the low coolant light won't come on anymore. However, you will now have to make sure you check your coolant level in the reservoir on a regular basis.
Why would the temperature gauge indicate an overheated condition when the engine is not hot. It could be the gauge in the instrument panel. Unlikey however. More likely it is a bad coolant temperature sensor or the wiring from the sensor back to the instrument panel. Inspect the wiring and replace the coolant sensor. The sensor is not too expensive.
Air conditioner or defroster on - normal should be running Vehicle low on coolant? Trying to keep engine in normal range Defective coolant sensor?
coolant temperature sensor is the right of the coolant outlet line on the top of the engine when looking at while standing in front of the truck. it has a black two prong clip attached to the sensor. the oil temp switch is to the left of the coolant outlet line. it has a single black wire coming off of it.
Bad sensor? There is a coolant temp. sensor that goes bad. Mine been on for over a yr doesnt mean it is low....just bad sensor.
I don't know but I would like to know as well.
Front of the cylinder head behind the thermostat housing. Location would vary depending on application. The year, make, model and engine info would help.
