Having issues with overheating have tried engine ice and everything else on the planet still overheats. Ordered a fan however the XC has different radiators than the exc and xcw for some ridiculous reason Im sure. Point is can't mount thermostat plug to radiator because there is no connection. My choices are buy new radiators or on/off switch don't like either one. Question: has anyone ever welded a connection to the bottom of the radiator and threaded to house thermostat. If so how did it work?
