nastyroxinc Posted January 6, 2014 Report Share Posted January 6, 2014 Hi all. The fan is now running all the time on the above bike. It seems to have been doing this since I last cleaned it. The coolant level is ok, all I've done so far is check the two connections on the thermo sensor with a multimeter and with a cold engine it gives 100% continuity across them. Before I order a new one, is there anything else I need to investigate? Cheers. Quote Link to comment Share on other sites More sharing options...

duggan Posted January 6, 2014 Report Share Posted January 6, 2014 Hi check the pipes from the water pump are getting warm? If the pump fails the coolant will trigger the thermostat but without the circulation from the pump it won't cool and the fan will stay on. Seen this a few times Quote Link to comment Share on other sites More sharing options...
nastyroxinc Posted January 7, 2014 Author Report Share Posted January 7, 2014 Thaks for the replies. Looks like it is the thermo switch then. Like I say, the fan runs from cold therefore I'm not sure it is an issue with the pump (I bloody hope not as I replaced the innards 6 weeks ago!) but I'll check.
