I installed a new radiator on my bike in January. Yesterday I saw my bike get up to 240° and didn't hesitate to take it straight home as I was 17 miles away. I kept turning it off along the way if I saw it reach 210 at stop lights. Further inspection and I see the radiator fan kindly melting against the headers! Why are there radiators for the 07-08 so weak with their brackets? I ordered a new fan b/c I can't salvage the old one. Is this a JB Weld job or a take the radiator out and go to a certified welder kind of job?
The pictures attached are of the old radiator being replaced and what I discovered today.

Since I can't see the failed tabs on the radiator that the fan frame mounts to I'll have to take your word for what the problem is.

Thin sheet aluminum doesn't like stress or vibration, particularly when there is a load on it. Aluminum tends to crack in those conditions.

I'm guessing that you purchased a knock off replacement radiator, and it wasn't a perfect fit. Some 'encouragement ' may have been required to get it to align?

It was a perfect fit, I pulled the radiator out today and used a steel stick to place the fan in place. Replaced the fluid and now the fan doesn't turn on at all. I watched it get up to 239°. Checked the fuse and its still right but I changed it as well.

In a “perfect fit” I wouldn’t expect the headers to melt the fan.

The radiator was a perfect fit. The tabs on the radiator were weak aluminum and broke. The headers melted the fan.

So, was it a radiator sourced from Kawasaki, or eBay?

Material quality, vs. mechanical load seems to be what you're thinking.

Why did you replace the radiator in the first place?

Definitely, replace the fan.....

First of all I can tell from the picture that is a chinese knock off radiator ( I have had customers try and bring me that shit and I won't install it)........... So, while it may have fit on the mounts that hold it to the bike, I am betting you had to do a little bending to get the tabs aligned perfectly for the fan to mount to the radiator, and even if not.................... It is chinese shit- what do you expect............. child labor and shitty pot metal and patent infringement and all that shit for 1/10th the cost it is bound to be garbage... you got what you paid for


So there, I feel better.... I got to pile on too........... This isn't a kawasaki issue, it is a cheap knock off shitty quality aftermarket part issue

go to a radiator shop and have it fixed or a welder and buy a new fan. That stupid glob of putty isn't going to do dick shit to keep it in place, besides you said the fan doesn't work anyways................. jeesus................

no soup for you

Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

That’s just Riverszzr.... the amount of b.s. that he has to deal with on a daily basis (repairing bikes) defies belief!

And everyone is saying the same thing.... The brackets can be corrected, by welding on new tabs. The fan is almost certainly destroyed.... The motor likely burned up when the fan jammed. A very few designs can self recover from a locked rotor, most likely this is not one of those.

If you want to make the repair cheap, try buying a used fan assembly off ebay, from a wreckers yard that gives you a warranty.

See the thing is;
My opinion is not a shitty opinion

You simply do not like my opinion because you made a bad purchase choice and now you are paying the price for said choices

So.............

NO HELP FOR YOU!

Jonathanhlmn, I am sorry to see you in such distress. Motor problems are a total PITA. I've had my share in 4+ decades of road going and racing motorcycles... and car/truck/SUV ownership.

YOU asked for assistance. You did not like the flinty honest answer that Rivers gave you. It's not you specifically, he's one of a handful of resident curmudgeons that frequent this site. The flinty aspect, well that's just part of Rivers' native charm. He gave you the correct answer by the way.

The man makes his living by fixing motorbikes. He is your brightest/best-est resource, at what cost to you? Be respectful, be truthful, take the man's advice or don't. But be respectful to all who give advice. Even if you do not like the sound of the response. Keep your own ego in check... And you just burned that bridge. He has a memory like an elephant, BTW.
