pb3 · September 16th, 2015, 10:18 AM

hi all,
well con't my catch up with periodic maintenance items, the manual says replacement of radiator hoses and o-rings every 3 years. i count 7 hoses and 5 o-rings. does K sell a kit? anyone else found this interval to be necessary?

bike in question is '09 with 12k
tia,

Hoses last for many years, especially if the bike spends a lot of time in a garage or shed (out of sunlight, away from ozone sources). I replaced my K75 coolant and fuel hoses when the bike was 14 years old as a precautionary measure, but I could have waited longer.

I replace o-rings when they leak. The coolant pipe o-rings tend to leak when disturbed.

The secret to a happy life is....

"Do not fix what is not broken."

Visually inspect your hoses and such. If they look worn or cracked or suffer any dry rotting, then replace. Otherwise, it aint broke and you are participating in a system designed to extract as much $$$ out of you as possible.

Well stated.

And if you inspect the o-rings, you'll be replacing them.

understood. i've got some of the blue green stuff around the thermostate housing and cap. but i'll just check for tightness, wipe it off and move on?

Yeah, but keep an eye on it. If it continues to weep, figure out where it's coming from: radiator cap; cracked radiator; hose/clamp; etc.

I'd snug that clamp up a bit if it were my bike. Then keep an eye on it.

It appears you got lucky!

Snug up all 4 clamps.

I got 08 with 65K. I never change the hoses and O-rings. Every time I check the coolant level, it is always full. the cooling system is great.
