Default CoolFlow fan

If you had one installed, what do you think of it? What was the install cost?

I had one put on. It takes a download to the ECM. In the display with trip A,B and the other data On, Off and Auto will show as you push the button on the left group. When I was on a trip going through a larger city a with red light each block for many blocks I put it to On otherwise I leave it in auto which I assume is set to go on when a temp sensor calls for it.

Without any gauge to reference the rear head temp I cannot tell how much it helps. The main idea of it is to pull the air going along the rear cylinder and direct it down to the area of the cat so it also forces the cat heat down.

I think the main benefit is for the rear passenger at stops to keep heat away from their leg.

Price? I don't know as it was all in the out the door price.

I wouldn't recommend anyone buying it unless their passenger complains of heat.

When it was introduced I suspected it was more of a passenger heat add on if needed than a motor heat improvement. You've confirmed that, thanks.

Thank you for your post. My wife has complained since the first day about excessive heat on her leg and right foot. Looks like I'll have the shop install the fan. I'll post my finding after the install and feed back from the wife.

I should have had one installed when I bought it. Would have been covered under the 7 year extended warranty. Not sure how long that fan is going to last.

I just had the 1000 mile service done and I had the cool flow fan as well as the fan assisted oil cooler installed. After picking up the bike the wife and I went for a 90 mile run. A mix of back roads and highway. Average speeds between 25-80 mph. The bike ran like a champ no issues at all. The motor was quite and the trans shifted smoothly and best of all there was no more excessive heat on the passengers right foot. Not like before! I'm very pleased.

The AMF Harley Nova project had a radiator under the seat with a fan that blew down.

Interesting how it works:

The CoolFlow Fan is almost invisible when mounted on the motorcycle, and features switched On/Off/Auto operation. In the On mode, the fan is active at low speeds, and will turn off when motorcycle speed reaches 40 mph. As speed lowers, the fan turns back on at 35 mph; this gap is intentional to prevent the fan from cycling on and off when riding close to 40 mph.

In the Auto setting, the fan operates based on a combination of slow vehicle speed and specific engine and ambient temperatures.

I sure hope Harley will make this available for older bikes. I have a 2016 CVO and my wife doesn't like the heat on her right foot. I have already removed the cat.

Something endemic to most if not all Harley's (unless it is a Limited) it would appear?
