What is the normal operating temperature?

[Hearn660]

Good day fellow GLers! My question is just that what is the normal operating temperature range?

I live in south Florida and it’s hot out, really hot. I went for a ride this morning and the ambient temp was around 90 degrees. I went on a quick 10 mile rip to see if I could see some turkey hens and chics feeders by this spot I know this morning on a quiet country road. I pulled over to take some pictures. While riding the temp stays around 175. I pulled over hopped off and left the the bike running. At idle the temp got to 215 with the fans running. I shut it down and could hear the coolant, I do not know the term so I will say bubbling. I hopped back on and put some wind through it. I’m ran it up to speed under low RPMs it quickly went back to 175 and stayed. I was just curious, was it because of the ambient temps being so high and I let it idle for about 5 mins with no air going the radiator?

Yes, when not moving it will rise to the fan activation temp of 210. It should be able to hold that with the fans cycling on and off every few minutes. The temp will cycle right around 210 maybe 200-220 as the fans turn off and on. When it's cold outside the fans won't need to run much, but when it's hot they may run almost continuously. When riding at speed it should be cycling right around the thermostat temp of 180 to 195.

I can only assume that you are guessing at the temperatures of the coolant since there are no temperature numbers on the GL1500 temperature gauge. How do you know what the coolant or engine temperature was?

As to normal operating range, with my 1998 GL1500 and the 1989 and 1999 GL1500's I have owned, the fans will come on when the temperature needle on the temperature gauge is in the middle of the scale. Anything less is normal. When riding in 90 degree weather and not sitting at idle, the gauge will indicate between 1/4 scale and 1/2 scale. At Idle, it will eventually climb to center scale or a bit more and at some point after that, the fans will come on and maintain that temperature. I have never seen it more than slightly above center scale.

Mike thanks bud I actually switched to a new info center in place of the LCD screen. It replaces the the fuel and temperature gauges. It is a plug and play that has a read out on the screen. I was just curious on the temp and make sure my thermostat was workin. Which it sounds like it is. Thanks for the response, here is a picture of the new screen.

Really nice set up. That must be that $400+ screen I was reading about not long ago. I'm liking the way it looks. I have to admit, I would love to have the same screen. Just need to give it a little more thought.

How complicated was the install?

It is time consuming as we both know there is a lot of plastic to take off. The actual install is basically plug and play. He labels everything and sends detailed instructions. There was a couple spots where i had to read them a couple times, due to the English isn’t the same around the world but east to decipher. I started in the morning and was riding by dusk. The guy Pierre that makes them is a super nice and helpful guy. He is in Belgium and the time difference was a little tricky but if you ask him questions he will answer them. I really like it and it is pretty customizable. He sends out updates and they are easy to download. Believe me if I can do it anyone can!
