85 Suzuki Intruder: doesn't the rad fan have a fuse?

Well, I already know from your question that you DON'T need to be told about your rad fluid, and you probably know how it works, and knowing how it works is not going to give you much help on why your fan isn't running.

It probably doesn't have it's own seperate fuse on the panel, obviously if it isn't listed. It may run off the main power fuse. There could be an electrical switch out, but most likely it is the thermostat. Especially if your temp light didn't come on.

It is not telling the fan to come on because it is not registering the temperature properly. This you will not be able to just do a quick fix on. It's a little tricky to get at.

The shop has PROPER ways of testing the electrical and the motor. I wouldn't be messing around with checking the wiring unless this is something you normally do.

Good luck getting home. You shouldn't ride it unless it is very cool outside.

When you stop on a hot day, for a few seconds the coolant gets super heated because the pump isn't moving it so it will expand a slight amount and some will be forced out. From the age of the bike, it is possible the coolant cap isn't holding enough pressure in the system or there isn't enough anti freeze in it. Both these things keep the boiling point higher to prevent it from boiling over.

i think there is fuse check all the fuses to see if any are blown if not find the hot wire and ground wire put power to the hot wire se if the fan runs
