1981 GL1100 Interstate

Post by oswoody » Wed Apr 03, 2019 2:40 pm



Does anyone know what the average engine temperature should be after a ride? my temp gauge was showing high. Almost to the red. I installed the new 7 volt part for the gauges. Still showed hot but also showed my fuel at half but was empty. Even after installing the new part. With a laser thermometer, the engine showed 190. The fan did not kick on. I installed a new fan switch. After riding, the temp never got above half. But when i got home, I check with the laser thermometer and the engine read 303 near the head covers. At the thermostat housing the temp was 190. Fan never kicked on and no indication of over heating. Anyone have any suggestions???

Possibly a thermostat stuck partially closed not letting full flow to the radiator. But if the engine was really at 300 degrees, you'd have been boiling out the radiator overflow, especially after shutting it off....

Thank you very much for the reply. Pretty much what I figured. I have a new thermostat so will have to install. But, at no time was there any boil over or any indication of overheating like before when the gauge went through the roof. Now it seems to be halfway at most. I did not check the radiator temp with the laser. Will do that next. But it didn't seem too hot either. I just have to figure out how to remove the radiator so i can get to the thermostat. Looks like you might have to remove the false fuel tank to get to a connection on the upper right side of the radiator. Thank you again for your help.

I had the same problem with 2 different interstates and on both of them I connected the fan to a toggle switch when riding around town i leave it on and on the hwy off haven't over heated or had any problems sense and on a hot day it shouldn't get over 270 to 290

Thanks. Before I put the new fan switch in I did the same thing. Although the gouge would go almost to the red it still had a temp reading of 190 to 200. I may go back to the toggle.

Unfortunately, the weather has not been cooperating here to ride test without the toggle switch and with the new OEM fan switch installed. Trying it later today and will let you know. I know that a lot of guys say it's cheesy to put in the toggle switch but to tell you the truth, it worked in the past so I am ok with it. I am just hoping that the gauge is ok.
