Tango Posted March 22, 2016 Share Posted March 22, 2016 Welcome to TMBF mate. ....pop over to the Newbies section and introduce yourself to the guys when you can. ....... Sounds like either the fan is duff or the temp sensor for the fan is faulty......sounds like you could do with checking the water pump and thermostat too.....

Fazzer1996 Posted March 22, 2016 Author Share Posted March 22, 2016 Hi mate thanks! I have checked the water pump that's fine, where would the Temp sensor be? I took the thermostat out earlier today and it seems okay to me I tested it in some water and it's not stuck or anything. Quote Link to comment Share on other sites More sharing options...

The sensor on my bike is at the top of the radiator, but yours could be somewhere else.... Quote Link to comment Share on other sites More sharing options...
JRH Posted March 23, 2016 Share Posted March 23, 2016 The sensor should be on the radiator either at the top or bottom and will have a wire coming from it. Quote Link to comment Share on other sites More sharing options...
