Where do I find the fan temp switch?
The easiest place to first check would be in the relay socket. We know the circuitry and fans are ok, since they work with the a/c and DLC. It is just a matter of whether the PCM is commanding them on by temperature. It could end up being a PCM issue.
Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
What should the fan temp be on a Camaro?
Only problem is my camaro isn’t an ls1/lt1, its a 95 rs. Anyways, im having the same problem as the op. My fans dont ever come on. The car was getting hot while idling but on the freeway, or at 45mph+, the temp stays between the 1/4 and 1/2 mark.
What should the fan temp be for low speed?
I ended up editing the fan turn on temperature to 200*F for low speed and 210*F for high speed. That makes the gauge look like the fan is coming on at the stock temperature. Does anyone have a suggestion as to why I am seeing this difference?

Why do the fans not come on when the a / C is turned on?
The fans do also come on when the a/c is turned on but they will not come on when the check gauges light comes on (cause it is too hot) I usually try to shut the car down at 235-240 if the fans don’t come on but this last time the ignition switch stuck in run and I couldn’t get it turned off quick enough.
Why does my water pump fan not come on?
Ok, so unpluging the ETC sensor in the water pump allow the fans to run. When the ETC sensor is plugged in the fans will not come on. I then replaced the ETC sensor with a new one but the fans will still not come on with it plugged in. Anyone have any other ideas? oke:
Where is the temperature switch that controls the activation of the cooling fans?
Where is the temperature switch that controls the activation of the cooling fans. I suspect mine are not coming on and need to change the switch/sensor. PCM sensor is the one on the water pump. Don’t change stuff without diagnosing.
When to turn on the cooling fan relay?
The cooling fan relay is an electromagnetic switch that controls the power supply to the engine’s cooling fans. It ensures that the energy-intensive devices only run when needed, usually when the vehicle is immobile. When the engine temperature approaches unsafe levels, the vehicle’s computer or temperature switch turns on the cooling fan relay.
How to troubleshoot an electric cooling fan problem?
1.Has the Cooling Fan Actually Failed? 1 If the fan comes on when the AC is running at MAX, but doesn’t run when the engine is hot, check the temperature sensor… 2 If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may… More
What causes a car cooling fan to run continuously?
2. A cooling fan temperature switch (or sensor, in some vehicles) can also get stuck, which may cause the fan to run continuously any time you turn the ignition key on or start the engine. Troubleshoot the switch. 3.
Can a bad fan relay cause an engine to overheat?
However, a bad cooling fan relay isn’t the only culprit for excessively high engine temperatures. Many other issues can cause the engine to run hot or overheat. Rather than uncommonly high engine temps, the driver may notice that the cooling fans have stopped running.
