I have just wired the fan switch on what i think is a polo rad. It switches the fan on at 105 deg and off at 104 deg. This seems a bit high to me. What temp should i use on a pinto.

isn't a pinto about 85-90 degrees?

i think the norm is on at 86 off at 81..

burton's do one thats on at 82 so i assume its off at 77.

if your not running a heater dont really need a thermostat.

The thermostat for the radiator fan in mine (Comes from a fiesta) comes on just over 100 and off about 95.

The one in my BEC comes in at 105 and off at 103, i think its fine as long as its able to cool the engine down, 110 being about as hot as you realistically want to see though.
