if my fan is running when i go to shut it down i'll usually let it run for a few minutes before i turn the key off. it runs up the hour meter with the key on so make sure not to forget about it.
Don't worry about it. If your fan is on when you shut off the engine it will not come back just by turning the switch back on, this is normal. It's gets pretty hot before the fan will kick on and with you riding thru some water that may have kept it cool enough. The reason the rubicon's fan works more is that it's a liquid cooled engine. Your foreman is air/oil cooled. On my wifes Brute Force 650i, if the fan is on when she shuts it down the fan will keep running, even with the switch off, until it's cooled down, this is normal for a liquid cooled machine.I'm not sure if my fan is working, i road for about an hour and a half yesturday, granted i was going to through water and stuff but since it was hot outside, and i could feel the heat of the engine on my legs, i never got a light on the display. should i be worried?
I say Idle with the fan on , reason is as you said the oil is circulating through the lower cooler and there is very little heat being produced from combustion at idle . I did notice though that most of the airflow from the fan is blowing over the engine cylinder head fins and not the cooler witch would help to prevent a hot soak if starting it again later.Anyone know if an air cooled foreman will cool faster with the engine off and the fan running or idling with the fan running? At idle at least oil is being circulated thru the cooler.
