Cooling Fan working or not?

How can I tell if the fan on the bike is working? I don't recall the last time I heard it. I thought of it because I've been feeling a lot of engine heat lately, not that they're related but it just made me think about it. I ran the bike this evening until I started feeling the heat from the engine on my legs and then brought it in the garage and let it idle for a couple of minutes. I thought that would/should make the fan come on, but it didn't.

The fans should come on when the temperature gauge reaches 3/4 of the way to H.

In my 10 years together I have never seen my temperature gauge rise above the halfway mark, always stays a hair below it. The fans seem to have a mind of their own. I think if my temperature gauge rose above the halfway mark something is going to blow.

I'm the same. The fans go on just below the half mark. Not that I see it move any, but this time of year it happens more often at stoplights.

If your fan isn't coming on at all I would check a fuse first.

You didn't say what year or model but I am guessing an 1800 newer than 01. On my 01 the fans would run everytime I pulled up to a stop sign. My 03 the fans never come on but I have a 3rd radiator which keeps the other fans from running. In general the wings are prone to the needle being at or near the halfway point unless you are in the worst possible situations. High altitude moving at 15mph with a tail wind and the gauge will go all the way to hot unless you stop or speed up. Problem is when you are in this situation it's normally on a mountain road with no pull overs in heavy traffic.

I believe after 01 the ECM was reprogrammed to alter gauge readings also fan engagement. The fan motors were also changed to a higher speed pancake unit which cools better also. Honda does not make the fans they are generic. If the gauge is at the halfway point and does not go above that than it's normal unless you get into the above situation.

Thanks! Just went out and checked the fuses. They're good.

Mine is a 2nd gen. as well. It takes a hot day or a LONG time setting still at idol before the fans will come on and at that not for long. Where my gauge sets after engine has warmed up and thermostat has opened..... doesn't take much above that for the fans to come on. Just remember..... it is the radiator temperature that runs the fan.... there is a sensor mounted in the radiator that runs the fans. I seldom have the fans come on during riding.... only on hot days caught at a stop light or stop and go traffic. The radiators really do a great job of heat exchange!

If you want to get more specific on actual temperature.... have to find some one with one of those temp guns. Then everything can be scanned for temp.

I have noticed that on my 2017 the fan come on a lot more often than they did on my 06. But the temp gauge rarely if ever has gone above the half way mark.

I suspect Honda set the max temperature gauge at mid-way so we wouldn't worry . Very clever.
