Hi
I noticed My stilo yesterday radiator fan was running once out of the car . When I went back an hour later it was still running. Went out and come home fan had slowed only because the battery was flat ? Jumped the car and fan came on again. Pulled ot the relay and it stopped . Put back in and started agin . I pulled out the regulator this didn't stop it. I left the regulator and relay out over night. Got a new relay today put back in the fan hasn't come in . So I put back in the regulator . Fan hasn't come on .!!! Any suggestion apart from the engine was to hot please I had only driven the car for about 20 mins and probably 15 miles .

Consult the owners manual (if not MultiECUScan) I think you can deactivate the system so you can just use like normal windscreen wipers.


They're known for it on the Alfas too - my previous 159 1.9jtdm, particularly on roasting hot warm summers days (when there is obviously no rain), would send the windscreen wipers mental for no reason at all.
