Re: Temp sensor for cooling fan

On the engine is only one temperature sensor, one next to thermostat housing
I think this sensor send temperature reading to ECU which control the fan on/off operation. IMHO

Re: Temp sensor for cooling fan

Temp sensor is on the head.

As a fail safe, if the plug gets disconnected the fan will run continuously.

If the the plug comes loose intermitantly making/breaking connection the fan operation will be erratic/intermittent also.
