'07 VN900 CLT I overheat whenever I hit 75 mph. Under that I can ride forever. The cap, pump, fan and coolant level are all good. I find no signs of leaks anywhere but after a few minutes with the temp light on I smell coolant.

Broken blades on the water pump impeller? Running lean at that throttle position?

Improper coolant ratio?

Since everything seems to be good here comes the oil question. Are you using the factory recommended oil?

Hmm stuck thermostat? I can only imagine these have a thermostat in them.

Check the anti-freeze percentage. Get a $5 hydrometer from Auto-Zone. The higher the percentage of anti-freeze the greater the chance of the temp lite coming on.

Maybe time for a flush and fill? I did that last winter.

Is it building cooling system pressure? Take it for a ride, then grab the most convenient hose and give it a squeeze. Is it rock hard?

Thanks for all the input. The thermostat is the culprit. As usual your all great.

I noticed my fan coming on more often as of late...
Wouldn't you know that by cleaning the radiator fins it cured my problem...


Glad you found the culprit as well...
