Little UP coolant temp seems to sit at 90 all day.
At what temperature should the radiator fan start ?

Theres another post on here about the temperature gauge, apparently sounds like its programmed to stay at 90 on the gauge even when it is actually hotter or colder than that! So what it tells you is not very accurate.

Guessing that the fan would come on at about 97 deg.

Mine NEVER comes on unless it's very quiet and I can't hear it.
We have had temperatures in the 30's this year so it should have come on.

If anything was up the warning light would have come on so not to worried but on my other cars the fan was always coming on.

Perhaps the little engine doesn't generate too much heat

I should have added this to the other post which was also started by me.......oops !Edited by: Derkie54
