Radiator Fan

Postby Devil-Doc » Sun Jun 03, 2012 3:57 pm



My bike is low on radiator fluid, will this keep my fan from coming on? It was working fine the other day?? Happened to be looking through the service manual, wanted to know where the radiator tank was, checked it today and saw it was right at the low mark and when I rode it for awhile noticed the fan was not working and the temp gauge was starting to go past half way mark.

It may not be of any concern.My 83 won't kick on the fan till the temp gauge is just below the red mark.
I did measure the temp with a IR sensor.The fan kicks on at 197* and off at 180*

Was kicking on sooner, does low radiator fluid cause this?

Low coolant level in the reserve/overflow tank will not cause any change in the behavior of the fan.
Coolant levels low enough to cause a change would have to expose the sensor to air....which is REALLY low in the block.

It is possible that your coolant level would cause the fan to come on sooner than usual because the temp gets higher quicker. It would not change the temp at which the fan comes on. If it is very inconsistent as to when the fan is activated, that is a sign that the temp sender unit is going, or is, bad. I included a photo of the approximate position of the gauge when the fan kicks on for my GL1100. The red arrow points to where the needle of the gauge is when the fan kicks on. This could be a little different for each bike, as the gauges can vary slightly. But I believe it would be close to where they all come on.

My fan comes on at the same temp as Pats......which is pretty much never, unless it's idling in the garage for an extended time.
