I'm at work, want to order a new cooling fan from offroadwarehouse.com, but I never did measure the size before I left home. Is it the 6.5", or the 7.5"?
If somebody knows for sure, I'll take your word for it and order. Otherwise I'll order it tomorrow after I go home and measure.

Thanks!

 

It's 6.5

 

Thanks! Oh yeah - are you positive??

 

So your finally going to replace your fan huh?
Did you try to find one that would work at a NAPA, Autozone or other auto parts store? I wouldn't think they had 1 specially made for the Bomb & you may find one a lot cheaper at a auto parts store.

 

yes Moose - the DS fan is supplied to Bomb from a company that makes all sorts of fans, and I can get one from offroadwarehouse.com for half the price ($70) of the dealership - same OEM replacement. Since its the same fan, it will fit the frame mounts with no modding.

I think a contributor to it dying is the fact that earlier when I used to have a RWR exhaust system the heat shield on the back of the fan was right against the pipe. My new Yoshi is using the stock headpipe, more clearance, less heat to the fan coil.

I'm also installing an inline temperature gauge on the radiator return line. That red light doesn't come on until 239 degrees, fan kicks on at 221. Since you can't hear the fan running when the engine is, this gauge can warn of failure prior to the red light, and also help to distinguish whether or not the red light is on for oil pressure or water temp (they share the same light).

 

The sales guy at ORW said they get so many orders from DS650 owners that he knows the part by heart and didnt need a part number. Was a tight install getting it in there and the heat shield the right way!
