You deserve to test the voltage going native the pan relay to the fan itself. If the is gaining 12+ volts, the fan should be coming on. Yet if it’s not, which way the fan has actually gone bad.

This video from Ratchets and also Wrenches is a phenomenal source on how to appropriately diagnose a wiring problem.

Engine Temp Sensor

Your engine temperature sensor is responsible for relaying her engine temp to the ECU. When the temp gets so hot, the ECU regulates the radiator fan to come on. If your Neon has actually a bad engine temp sensor the radiator pan won’t know to come on, since the ECU won’t understand how hot the engine is.

You’ll have to locate and also test the engine temp sensor. Relying on the design year and also engine, the place varies. If that does end up being this sensor, they are really affordable.

Low Coolant


If the engine coolant level isn’t high enough to keep pressure in the engine it will certainly run hot. But, over there won’t be sufficient coolant to reach the temperature sensor. Without the coolant hitting the sensor, the temp analysis will be significantly lower than the actual engine temp. Your Neon’s radiator fan will not kick on.

If girlfriend do have low coolant, don’t fill it up until the engine has actually cooled off. Adding coolant to a radiator dry enough not to trigger the engine temp sensor can cause problems indigenous drastic temperature change. Let the cool under first.
