Yes, but it is not recommended to run straight water in the cooling system.
There is one in the reservoir and one in the coolant tank. They probably replaced the one in the reservoir. My 96 is doing the same thing and the dealership replaced the one in the reservoir but the message is still coming up. I found out on another forum that it is the one in the tank that needs replaced. So I would check that out. Hope this helps. if its not the sensor,its the sensor plug.if that doesn't help it is the connection to the computer on the firewall.its in back of the coolant reservoir.ive never heard of the tank thing,no such thing also if there is air in your system, (air will enter from leaks in your system) when the air passes the sensor it throws out bad coolant sensor code, due to the rapid temp. change from that air bubble, if there is air in the system and not pumped out it can cause a blown head gasket, very expensive replacement
Water is coolant!!! Pre mixed coolant comes with anti freeze and sometimes a rust inhibitor, other than that it does same job. Common sense being your guide. Do not use straight water during the winter. Varying ratios of water mixed to antifreeze will actually increase the boiling point in both winter and summer and is more benficial in summer in terms of cooling function. More Coolant/antifreeze less water (mixed) increases boiling point correspondingly. It is of greater benfit to use coolant/antifreeze in your engine because it prevents rust and corrosion in the various parts of cooling system and heating system (heater) and increases the boiling point. Check the coolant/antifreeze container for instructions on mixtures and learn from it.
Two sensors in the same part, yes.
There is no knock sensor on a 94 4L jeep engine. In 1991 when they changed to the 4L HO motor, they removed the knock sensor from the system.
Yes.
The engine coolant temperature sensor and coolant temperature sensor are the same.
The coolant temperature switch and the cooling fan relay (same thing) is usually located in the water outlet housing. It will be the bigger sensor, the smaller is the temperature gauge sensor.
http://www.lovehorsepower.com/SubaruDocs/CoolantTempSensor.htmlits a 1995 but same thing
The coolant fan sensor is the same as the sensor that shows the coolant temperature on the dash gauge. It is located on the intake manifold.
Antifreeze and coolant are the same thing.
You coolant level sensor has stopped working, my 93 olds regency is doing the same thing. You will need to goto the a Buick/GM dealership to get the part, it plugs into the side of the radiator.
Sensor, wiring, or computer. Those are your three options.
Yes

no, it is not.
Yes it is.
My 1992 Spirit does the exact same thing... its either the Coolant Temperature Sensor that screws into the engine or as in my case a faulty Temp Gauge.
