Radiator leak

[Mongler07]

Mine did not have anything in them i kept as spares looked as good as new might have been the type of antifreeze that was used.

That is possible but in my general amature automotive experiance, those hoses were very poor compared to say VAG group or ford (motorcraft) that looks still in great shape after 100k and 20 years of constant use. VS a under 20k bike that stayed in a garage most its life.
My ninja hoses with 60k on the clock felt better than the hoses I got new from triump.
That's just my experiance. Triump is not known for its robust quality for outsourced parts.... that goes for any "British" motorcraft.
The rubber degradation was probably due to a bad coolant in some way.... for sure! But I have had bad coolant on VAG cars that dis not show this bad with 300k on the clock.
My tdi had stock hoses at 260k and that's when I did my flush, it had mixed very bad acidic coolant with lots of brown precipitate. No rubber damage.

And I will say that the silicone hose kit was extremely high in quality and I would recomend them as a good upgrade.

Was reading this old post and will add that i finally got tired of the few drops of coolant that were leaking, no big amount to be sure. I put some fresh thread sealant on the bolt and screwed it in and then put jb weld all around the bolt on the outside. I have not had a drop leak since. The chrome trim piece is secure enough without that particular bolt. I guess i just never thought about the bolt puncturing the radiator, but now i do. Should have a leak free triumph on next oil change, have one of the oil drain bolts leaking just slightly and have 3 new washers for those bolts.

Or... Just use a new copper crush washer. No amount of any bs on the outside will do jack squat. Threads are not tapered and water does not come out there so that was pointless.

Water does not come out there? Yes it certainly did, flowed like a faucet with the bolt out and drip with it in, now nothing. Quite possibly a crush washer would of stopped it but at the time thats what i came up with and no more leak. That is one good thing about this forum lots of ideas.

no... i mean the threads.... putting thread sealant is NOT going to do a dam thing because water (coolant is NOT behind the threads) is what i meant. you can always just sand down the washer and make it cheery red with a flame and quench it.
