Coolant Temp

Did a search on this and found some good info, but none actually fit my problem/worry.

I'm getting swings in the temp gauge from just below the mid line to mid way between there and HOT (today was 85 ambient)....I've checked the coolant level and I can see it in the over flow area. As long as I'm at speed the gauge is ok, but if I hit traffic or stop lights the gauge creeps up.

Is this normal? and how close to the red should it go before it's a problem?

Re: Coolant Temp

Sound quite normal to me.

On my 2002, at speeds over 25-30mph when I am rolling along steadily the needle stays below the halfway mark. In slower, or stop-and-go traffic, the needle creeps upward into the upper half of the range. If I am stopped for any time at a light, I may hear the fans come on when the needle reaches 1/2" or so from the red. While the fans are on and the airflow is warming my legs I watch the needle drop down to a bit above halfway or so.

Once traffic clears and I am rolling along the needle drops back down and stays below the halfway mark.

I have yet to see the needle reach the red area. No red, no worries!

Re: Coolant Temp

As long as your fans kick in, it is not a problem. Just keep an ear out when the temp creeps up to almost red they will start up. Temp goes down pretty quick to normal once riding again.

Courage doesn't always roar. Sometimes it is the quiet voice at the end of the day saying " I'll try again tomorrow".

Re: Coolant Temp

Thanks for the replies.....guess I'm being a little over-reactive to my new toy.

Re: Coolant Temp

When I had my LT when I hit traffic, even with the outside temperature at 30 degrees, the temperature gauge would creep up and fans come on.

Re: Coolant Temp

Normal. The only time mine got into the red was when one of the fans had somehow become unplugged.

If yours does ever get into the red, make sure BOTH fans are coming come on.

On my 2001, when it did get into the red, there was a warning light on the dash that got my attention before I noticed the temp gauge.

I don't want to achieve immortality through my work...I want to achieve it through not dying.

I'm sure your car does the same thing - modern liquid cooled bikes are set up exactly the same - everything uses electric temp controled fans, cars used to have a fan attached to the water pump on the front of the motor that spun all the time therefor no big swing on the temp gauge

Fear not, I too was super concerned about the dramatic swings of the temp needle, but I have come to get used to it. As mentioned above as long as the fans kick in you are fine. A couple days this summer when it was hitting around 115 and I was sitting in traffic on my way home I was white-knuckled that I might have to join the HD guys under the overpass, but when the fans kick in they really do their job, I just wish they kicked in a little sooner. Living in a blazing inferno overheating is always on my mind and watching that thing go up and up still makes me nervous even though I know the fans will catch it.

Relax and enjoy the bike.
