What's worrying me more is that it looks like the fan blades are feked. That's another 500 quid per blade.

I think I might phone kawasaki on monday and ask some questions. I can understand a radiator getting damaged from stones, but from an actual kawasaki components?

[O.C.]

Currently radiator is completely off the bike so it can get fixed. I just want to make sure I have the refill sequence correct:

1. Attach hoses back to radiator. Is there anything special I need to do here like cleaning the connection points?
2. Fill radiator with anti-freeze by removing radiator cap. Note, this the cap on the radiator and not the reserve tank on the left fairing.
3. Fill the overflow bottle to the correct fill level
4. Start engine and monitor for leaks
5. Let engine cool and refill radiator and reserve tank

Does the above sound correct?

My advice is

    1, Clean around the rad pipes with a bit of scotchbright..nothing too aggresive and dont let owt get inside the rad.
    2, I would make up a mix of antifreeze/coolant with some tap water and pour into rad, with hoses connected of course
    3, correct
    4, run the engine gently with rad cap off to allow for escape of any air locks
    5, yes

Thanks for that barney. Although they look the same, the zzr one only accepts one fan. Also, I've been informed there maybe a size difference.

Aye, there's a very subtle difference where the fans attach at the top of the radiator. Notice the GTR bracket accepts two fans where the ZZR one accepts one fan.

However Barney, I think your idea has merit. I'm thinking of making a bracket and welding it onto the ZZR radiator. That might work (assuming there are no other differences)

EDIT: The problem is attaching the fans. I'd have to weld a piece to the top and bottom for the right fan. Is it worth doing or is it more risk?

Looked at why those marks might have been made. Someone suggested that something might have got caught between the fans and radiator. That is highly possible. The fans are rigid and not broken. I placed the fan on the radiator to see how much clearance there is. Not much.

The slightest pressure on the fan and it was touching the radiator. We are talking probably a couple of mm. I think I'll add some additional washers to get more clearance when reinstalling the fans.

(Now that I think about it, sometimes I could hear a noise like the fan motor was going. I'm wondering if it was the fan touching the radiator very slightly)

 after carefull searching they maybe alot different there are alot of radiators and they start with 39601 its the code after this

you would expect to see witness marks on the blade edges

[Kwikasfuki]

There are none. The blades are actually recessed into the housing. However, you're right, I would expect to see marks on the housing as that rotates with the fans.

Radiator is with the repair shop. Will ring in a bit to see the damage

Shame nobody seems to go good value aftermarket radiators for bikes. I have just had to buy and fit a new Behr radiator to my wife's 740i, it is 4 times the size of the GTR rad (though admittedly not curved) and came in at a whopping £108 delivered brand new.

Admittedly BMW wanted £450 + VAT for the same thing, but Kawasaki's price is laughable. There is a 2009 ZZR1400 radiator for sale on eBay at the moment, 5 minutes browsing the www.cornwallkawasaki.co.uk parts fiche would see if the part numbers are the same.

If there are no witness marks on your fans, I am wondering if a stone somehow got caught between the fan and rad. Odd given the fans are on the back. You did not drop a bolt down there whilst the fans were going per chance?

Hi Martin,

The ZZR and GTR radiators have minor differences (see earlier in this thread).

Possibly a stone or maybe even a screw when I was tinkering on the bike. Can't recall ever losing one down there. In future I will always ensure the fans are free of blockages after working on the bike.

I've been quoted £280 for a new core, or £40 quid for a repair. I'll be going for the repair and keeping a lookout for a radiator to replace at a later date.
