I just picked up this bike because I wanted a bike I could go on rides with my buddies that have street bikes, but still get out on the trails. I've talked to some of the guys that ride on the mountain trails I plan on playing on and they tell me that most guys on 4 strokes get a high flow impeller. Is this necessary? Are there any other things that I should do to prevent overheating? I did blow out the plastic T on a short 2 mile trail ride which I promptly replaced with the Uptite Y. I also cant' tell if the fan kicks on. What would be the best way to check this? I'm definitely lacking in my mechanical knowledge and any and all help is greatly appreciated.

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
High flow impeller 06 TE450

The stock 2006 450 does not have a fan.
I put an 4" SPAL pusher fan on the front of my 06 TE450 right radiator since there is no room on the back side since I have a 3.9Gallon IMS tank on. Used a 200F thermoswitch to trigger. Without the fan, I loose mucho coolant on slow S/T sections.
I also put a Trailtech TTO digital coolant temp sensor on. With fan I never exceed 200F. Without fan, over 245F easily.

I have the exact same bike(06TE450) and ride in Norcal from sea level to 8000 feet. This bike does and will over heat when ridden in tight 1st gear single track, long 1-2 gear climbs, and any technical area where a lot of clutch work is required. I would skip the high flow impeller. From what I have gleaned, there is plenty of flow from the oem impeller. In fact, there are some that have actually put a restrictor in the Y pipe to slow down flow so the water spends more time in the radiators. Make sure your jeeting isnt too lean (this will greatly contribute to overheating). My solution was to add a 4" Spal puller fan behind the right radiator with a manual switch. $35 on ebay.
I aslo run a trail tech vapor with temp gauge in upper right rad hose. So while it may not be spitting out water, I have seen 260 degrees without the fan. Dont let the fact that it isnt spitting water lull you into thinking the bike isnt too hot.
BTW, this is with fresh quality coolant, a good rad cap, and proper jetting. These bikes DO overheat easily on the Mtn goat trails. I believe that Ziptye Racing went so far as adding an oilcooler and larger radiators. The 4" Spal fan has been more than enough a solution for me - and its cheap. Same fan as OEM on the later year models.
