929 radiator repairs

So, I have just cleaned out and flushed my 929 radiator.

Been 3 years with no cooling/leak issues, but thought it time to put some new fluid in, while I did some other maintenance.
Drained old coolant, flushed system with clean tap water, twice.
Fluid that came out in the flushes did not seem dirty, tap water ran out clean with no sign of rust or gunk etc.

I then used some Wynns radiator cleaner (supposedly compatible with all engine components) mixed in with the water, then started up the Blade. After about 5 minutes and at 80 C, the radiator starts steaming big time, and leaking from the bottom left and top right areas.

Bummer, how could it start leaking like a sieve after no leaks in the 5 years I've had it ?
I had my doubts about the radiator, as it has heaps of old dents in the fins from rocks etc. Previous owners must have been on some rough roads !

So, I have priced new 929 radiators, they seem stupidly expensively priced from AU $ 500 through to about AU $ 1300, going from research on the net.
What to do ? New one/second hand/repair ?

Bladeracer, if you read this, can you recommend anyone you know of in Australia who sells/ repairs 929 radiators ? The price of a new radiator is just plain crazy shocking !

Thanks for anyone with advice !

I'd be guessing the additive loosened something up.
Exactly where are the leaks - are there holes in the aluminium, or are the hoses leaking? You can take the rad to any shop or radiator specialist and have it pressure tested, and it may even be repairable. Otherwise, it might just be the hoses that are failing. If it's been running water, or the coolant hasn't been replaced regularly, it's common for the outlets to corrode inside the hoses. Probably also repairable but unlikely to be worth it, the inside is probably in similar condition.
New out of the US you're looking at around $450 plus post, Ebay US should be pretty reasonable. If you get a 954 rad it doesn't have the thermo switch - you would have to put in a toggle switch to run the fan.

Re: 929 radiator repairs

You do know a radiator is a radiator. I usually go to any auto radiator repair and they fix it with no problem. And once i went to a regular aluminum welder and he welded a hole for me in my radiator but I knew where the hole was and no pressure test was conducted like a radiator repair location. It was ugly but it worked.

There are a bunch of radiators on ebay for $100 dollars and up used and new.

Re: 929 radiator repairs

Thanks for the tips, much appreciated.
Bladeracer, thanks for the links, it was very useful to identify the radiator part numbers and stuff.
I may as well replace the coolant hoses too, whilst I'm at it as they are 14 years old now.
The leaks from the radiator are hidden behind the cooling fins in 3 places on the radiator. I guess the cleaning additive worked too well !

Will pull the rad off and get it into a specialist repairer next week.
Thanks again, mates !

Re: 929 radiator repairs

I had to bite the bullet and buy a new 929 radiator.

Got it from Partzilla in the US, much,much cheaper than buying from a dealer in Australia !

So, the new one is fitted, no leaks from hoses/switch, etc. All good.

But now I am getting drips of coolant from under the water pump, so I guess the seal has gone.
Am going to buy a whole new pump and fit it, but I have a question or 2.

Do I need to drop the engine oil, as well as the coolant ? Will oil piss out when i pull the pump assembly from the engine block ?

Any other tips for 929 water pump removal/assembly ? Do I need to renew any other seals ? Cheers. Jack.

Lean the bike against a wall and you shouldn't lose much oil. Be sure to grease the o-ring when reinstalling the pump and take care that it goes in all the way around.
