I have one of these. Watching this.

I was saving for one, almost bought it from race inspired, but I said, "feck it, I'm buying a stock one until I hit 400HP...

I picked up a decent OEM quality radiator for about 160 shipped...

the only reason my old one failed is that I had a kink in my hose that runs from the radiator to the collection tank...

what's wierd is that the 91 Legacy Turbo radiator cap is a 13psi radiator cap, which the full aluminum radiator should have NO PROB surviving. I'm guessing the jig for the welding isn't fitted properly or is bent...

Any competant radiator shop should be capable of repairing a full aluminum radiator, even if it's closing off that one vein... it'd just be a matter of cleaning/etching and welding... even if there's a chunk missing, the full aluminum radiators are repairable...

Kenyon Machine in San Diego could handle the weld job... I've seen an aluminum V8 head with a crack, repaired back to new.. *fararri 388* I think. AND they're cheap cheap because they have been around for a long time.

well guys i got some good news!!

i called koyo agian today and this time i got a hold of the performance rad department head guy, hes a very nice gentelman and i showed him this post and told him all about the problems a couple of use are haveing with our rads.

i told him about the rads breaking in the same spot and he is going to work with use to resolve the problems.

he also told me that our legacy koyo rads are the only ones made bye hand.

so hopefully the pepole with the broken rads like the two i have in the same spot will get new ones so we can enjoy our raceing rads with out any other problems.

This is good news!

(going out to take pics now)

So what are we supposed to do? Do I need to get ahold of this guy? I still have the Koyo packaging if he wants me to sent it to him.

I don't think you can weld the core tubes to the end tank since they are brazed. You'd have to weld all of them. I would think that they could re-braze it.

OMG you see your inspection tag, thats the same inspector that inspected my rads. who ever cheaked the rads should be fired for makeing us have to go threw all this.

imagin how many other pepole are out there with this inspection tag the same as ours!!! this might not look to go for koyo, i got two you got one so far thats three rads down!!!!

i spoke with him he is watch this thread very close, the best bet would be to call him up its the california branch ask for K head of performance rad branch and tell him your pics are up in the thread and ask him what he wants you to do. this is your best bet, becuse you might have to speak with the guys that got you the rad and deal with them first then he can help you out like what i have to do.

but make sure he goes to this thread and sees your post while he is on the phone with you so he knows everything

any update on this issue..i need to buy a new rad

i keep try to get new rads and am talking to koyo but i have no clue monday i am going to go back at this.

also did you call them and let them know where you got your rad from becuse do that first!! and i think you should send the rad to them and tell them to ship it to koyo

well i dont have a koyo now now but i need to boy one very soon. just want to make sure i don't get one out of the "defected" batch

I've been so damn busy I keep forgetting to call the guy.


NICO, who am I supposed to talk to? Do you a name or a number?

I was all about getting a Koyo radiator for my '92 SS, but not if they are having problems with these. Yes, I realize that only 3-4 of them having problems is a low count, BUT if they are leaking from a similar spot that up the possibility that others who are not on this forum may have the same issue.

Also those outside people don't belong to this forum, they aren't aware others share this problem and need to make Koyo aware of it.

I have an extra OEM turbo rad, and it looks like that's golden for me at this point. I've also pointed this out to a few local guys that were thinking of jumping on the Koyo bandwagon & are holding off to see what the out come of this thread is.

NICO, I sent you a PM.

Any more info on Koyo rads? Puddle in the driveway says I might have to buy one.

Also wondering if the stock fans and shroud bolt right up to the Koyo?

Thanks.

MY second one was solid after that. The koyo's that went bad seemed to be made right around the same time.

Yes, you should buy one and yes stock fans and shroud bolt right up...

1 year and counting on mine with no leaks...

<knocks wood>

Done two hot track days with it and engine temps never went high (235 if memory serves me)...

Get lots of complements on it too. Because it's bad-ass...

Cheers,
AW

good to know. i never saw this tell now.

Mine popped in the same spot. I believe I purchased mine around the same time as you all, but my radiator lasted a little longer, before leaking. Took it to a local shop and they said they cant repair it (can use an epoxy but wouldn't trust it on a race car).

Did anyone ever get a warranty from Koyo? If so who do I need to talk to in order to make it happen?

this is why i bought a mishimoto

I trust them less.

Two years and 24k later mines still going great strong. Knock wood. Not leaking. It was professionally installed by the best tho.

Subject: Koyo Radiators

Hello Tyler, we received your message regarding your radiator. Our product policies and warranty procedures are located here on our website: http://www.koyoradracing.com/policy.asp Determine whether your issues qualify for a claim, and follow the procedures listed here. Thank you.



My reply:
I can see your point in your warranty policy and would agree with it under normal circumstances. However it doesn't say anything good about your product that so many cases of an identical failure happened to a specific group who all purchased the same model of your radiator around the same time.

Here is the link to a group of your radiator failures. All of us have the same application (Koyo R1819) and have had the same results. Please check it out the following 2 pages describing the failures: http://bbs.legacycentral.org/viewtopic.php?f=5&t=36433

And another case: http://forums.nasioc.com/forums/showthr ... ?t=1465216

Also all of us purchased the unit from the same dealer who is no longer in business.

Like I said, I understand that in a racing situation, I completely understand your policy. But its hard to not be suspicious with so many identical failures at the same time. I believe we all used the "R" radiator because you didn't have another option.

I would love to see you stand behind your product but if not that is fine. If that is the case I will definitely take my money elsewhere and recommend the Subaru community due the same.

Thanks,
Tyler

What was the outcome? I'm in search for a replacement myself and want to see if it was just a bad batch. Anyone else have updates? Did Koyo come out with a non-racing replacement for the SS?

Mine started leaking today in the same spot.

Has anyone gotten through to koyo? Should i suck it up and buy another one?!

i would buy a new one. koyo was no good to work with. i did patch my leak with jb weld for the time being. trying to find a replacement that isnt koyo or mishimoto.
