1-Changed coolant temperature sensor, still overheats
2-Tested fan directly from battery %26amp; worked repeatedly
3-Changed the oil recently
4-Checked the connector %26amp; fuse, all good
5-Did not do a chemical flush but did change was changed, old was in good condition
6-Seems like the fan comes on sometimes %26amp; not others (hard to tell %26amp; look down on freeway)
? - Where is the relay located on the bike for the fan
? - Where can i find a wiring diagram free
? - Any other good ideas to check %26amp; description on how to do it2002 Honda Shadow Sabre Overheating?Sounds to me like either your fan switch (thermostat switch, attached to the thermostat housing turns the fan on) , the actual thermostat, or the water pump is bad. Start the bike with the radiator cap off, and watch the coolant. When the bike reaches temperature, and the thermostat opens, you should be able to see the coolant level drop, and circulate in the radiator. If the thermostat is stuck shut, it wont drop or circulate, and if its stuck open, it will circulate constantly. If it does either of those, the thermostat is shot, it needs to open and close completely and cycle correctly. If the water level drops slightly, with no circulation, your water pump is not circulating the water, and needs to be replaced.2002 Honda Shadow Sabre Overheating?seems you listed everything in the coolant system except the thermostat, could be getting stuck.2002 Honda Shadow Sabre Overheating?ditto %26quot;roadawg%26quot;. Also, see if you can have your radiator cap pressure tested.
You are probably looking for %26quot;thermo unit%26quot; #33 and %26quot;switch assy, thermo%26quot; #34
You'd have to have a shop manual to trouble shoot them.
