Radiator fan

[Komet_V2]

If just looking at the temperature guage, when should the fan kick in? When the dial moves beyond the centre? Mine seems a little inconsistent when it has come on. Odd time, thinking it should be coming on.

Someone said I should get a switch so that you can put it on when you want in case sensor goes

Generally a little past the middle , sometimes 2/3rds up the gauge , no need for a switch if the system is maintained and working fine, it will regulate the temperature automatically
