RPM Electric Clutch Fan Review

[JTBarlow]

We installed the RPM ECF on my Brother’s ’25 Xpedition XP5 NS from brand new and every time we were riding together he was reporting 20°f+ lower belt temps than I was running. Both our Xpeditions have belt temp gauges installed so we can see what the belts are running when pulling our Camp Trailers.
With my ‘24 Xpedition XP Ultimate being one of the first to arrive after they were released, I have a few years of belt temp data to compare with.
I finally got around to purchasing and installing the RPM ECF last week, just before heading up to Little Sahara Sand Mountain Dunes, and the difference is amazing!
Last year, riding Sand Mountain, my belt temps peaked over 260°f and with any pushing stayed above 210°f.
This year, with the ECF installed, my belt temps peaked at 208°f and averaged around 174°f when not climbing the mountain itself.

The RPM Electric Clutch Fan Kit
(RPM Polaris XPEDITION "ECF" Electric Clutch Blower Fan Kit
Was very easy to install, simply plugging into the driver side taillight harness and using the RPM Silicone Clutch intake tube replacement (required to install the ECF) though I cut the wires near the fan and added a harness plug so the Fan can be completely removed when doing clutch/belt work, without removing the entire wire harness.
The price, like the majority of RPM’s products, was quite reasonable. At a grand total of $346.70 for both the ECF and Silicone Intake Tube, I feel like the extension of belt and clutch life will pay that back easily.

Overall, this is a highly recommended upgrade for anyone who likes to use their Xpedition to its fullest.

I installed one on mine and I am happy with it so far.

Had one on my last rzr as well.

Gee, I wonder if that would be useful information for someone who lives somewhere where peak summer daytime temperatures reach nearly 120 and typically has over 100 days of temperatures over 100 degrees?..!

Yeah… I live in a place like that!

But even when you don’t, belt temps all depend on how hard you push the machine and type of terrain. Last year at the dunes the ambient temperature was around 85°, and my belt was running 250°-260°, and I had to stop occasionally to let it cool off. This year, ambient temps were around 80° but with the ECF I never needed to stop for cooling. And I pushed it every bit as hard as the previous year.

what are you using to monitor the belt temp ?

We installed Razorback Belt temp gauges on both my brothers and my Xpeditions.

thank you

thank you

is there a specific model, and could you share some pictures of the install of the sensor.

Their older model gauge was non-dimmable. That’s what’s on mine. The newer gauges are dimmable and need a rocker switch slot for the dimmer/program switch.
3.2 Dimmable Infrared Belt Temp Gauge | Razorback Technology

With my Xpedition being an Ultimate, I have the vent covers for adding switches and gauges. The Northstars are more limited on mounting locations.
I found on my Brothers Northstar that with being very precise, the gauge just barely fits between the instrument cluster and side.

I did have to carve just a little off the instrument cluster lense, behind the dash, for the gauge to fit, but it was minimal and didn’t break the seal of the instrument cluster.

On mine, I ran the sensor cable up the a-pillar, back along the cage and down the rear pillar, and then back to the clutch housing.
On my brother’s, we installed it at the same time as the Turn Signal Kit, so the sensor cable was run along the bottom frame near the driver side, and then up with the factory engine harness and over to the clutch housing.


There’s pretty much only one spot with enough space to fit a drill and that’s right behind the throttle body. (If you have the ADV it’s going to be bit more work than the XP)
To mark where to drill, I bent a piece of wire…

So the sensor would be centered on the belt. Make sure to remove the belt and secondary clutch before drilling so you don’t damage either.

Razorback has a QR code link for their install and operation instructions. I don’t think they have instructions specific to the Xpedition, but they’re clear enough.

got it... I also have the ultimate ADV

One more question, did you power up your gauge using the ignition trigger wirer or a separate switch to turn it on or off. I noticed the gauge doesn't draw much amperage so it might work of the pulse bar ignition wire.

It’s just wired to the pulse bar, keyed power.

And on the Ultimates I use the vent covers for extra switches etc.
they’re convenient for that
