When I do my radiator, I'm going to fit the 82 degree (rather than 90 degree stock) thermostat. My question relates to the interplay of this thermostat with the fan switch. There is a 91/100 degree stock one and an aftermarket 85/90 degree one.
The guys at Awesome GTi said that on our Polo the fan control actually looks at the engine temp and the radiator temp as seen by the fan switch.
So to my mind if I change to the lower temp thermostat, I'd pretty much have to be running the lower temp radiator fan switch too wouldn't I so that the two marry up?
anyone gone down this path??

any advice welcome as I need to get onto ordering bits before my radiator has a haemorrhage
