Radiator Compatibility???

7 posts in this topic

Hello,

My 98 WR400F suprised me yesterday with a leaking throttle-side radiator after I gave it a bath (how unthoughtful). I still have more diagnosis to do in order to make sure that it is indeed leaking from the radiator and not a hose, but the inital impression is that it is leaking from the radiator. After cleaning my 'drawers from the sticker shock of the OEM replacement ($312!), I figured I would begin looking on the used market. Question is: Does the 98 WR share radiators with other models? It looks like the YZ/WR radiators have remained unchanged up to the current models. Does anyone know this for a fact? What about other Yamahas like the 250's? This would increase the odds of me finding a used one. Thanks in advance for any input.

I know, I know - A set of Devols (or something comparable) is in the near future... :awww::lol::thumbsup:

The thing that you really need to look at is how the radiator shrouds connect to the radiator.

I think the 2001 models changed, but I am not positive when it happened.

I have a '98 WR, and I saw some radiators come up for sale, and I did not do my research, and the radiators that I bought do not work for me.

Yes, they bolt up to the bike, and all the hoses match up to, but the shrouds are mounted at a 45 degree angle (on the radiators that I bought) and my shrouds ('98) mount up flat.

If I bought a new style of shrouds, they would work (but, then I would also have to get a new set of radiator guards ) but, as it is, they sit in the garage.....

You are smart for doing your homework.

Good luck!

:thumbsup:

Thanks for the feedback guys. My local radiator repair shop will repair mine, but they don't specialize in motorcycle radiator repair like the place in mention. I also noticed while browsing through the yamaha parts catalogs that the shrouds begin to mount differently at some point... :thumbsup::awww::lol:

Brandon,

You are right about the shroud mounts... My radiator has brackets that are 90 degrees from the actual radiator. I looked at a set on eBay from a 2001 YZ426, and the shroud mounts come off at about at 45 degree angle. Thanks for the heads up! I don't know when they changed the rads, but I would have been in the same boat as you... :thumbsup:
