Change Radiator Hoses?

From a preventative maintenance point of view, at what mileage would you replace all your radiator hoses?

I've kept hoses on bikes for 15+ years. I think it has a lot to do with your individual use.

I just keep an eye on mine.  If they start to show any cracks or start to feel stiff when you squeeze them, it's time to replace.  But generally they last much longer than the recommended service interval which I believe is 4 years.  I have a 2002 ZRX1200R with the original radiator hoses and they are still like new.  A new set is fairly expensive so I'm not replacing them unless needed.

I replaced mine at 6 years & 118,000 miles, just seemed like cheap insurance. Most of my riding is long distance. If I was always within in my home state I wouldn't worry about it. They appeared to be fine at that point.

Thanks for the info, I have about 60,000 miles on my 2009, maybe I'll just give everything a good inspection, check the tension on the clamps and call it good.

Another thing to look for is "crusty" deposits around the connections.  If coolant is seeping out it often evaporates and leaves deposits behind.  Usually indicates the hoses losing their ability to seal.  Tightening the clamps can help for a time but eventually there is nothing left to compress.

What ever happen to the aftermarket hoses that were being made.

There was a thread about them.

They are in the UK but if you do some research you'll find a U.S.A. vendor.

The Samco hoses are nice, and can be really cool if you want to color match your bodywork (on a bike that allows you to see the engine) but at almost US$300 for a set, wow, that's a lot of money.  I think the OEM hoses are quite a bit less than that.

I would have replaced them before 118K but Its probably a good idea on this bike around 50K.

I'd say it depends on the type of driving.
Enemy of hoses (and other rubber items in the engine area) are heat, and time at high temperature.
Long jaunts on roads clear of traffic are probably going to keep the hoses cooler: Coolant is at lower temperature, and the outside of the hose are getting cooled by the air. Stop & go driving in traffic will keep the hoses at higher temperature for longer periods, and age them more.
The high temperature "bakes" them, and makes them hard and brittle.
When I replace mine, I will probably go with the silicone (thanks Mike for posting the URL), as silicone is much less affected by high temperatures.
My 2001 Suburban (216,000 miles) still has the original hoses, and they look good. Most driving has been highway driving, so little "baking time".

I've kept hoses on bikes for 15+ years.

Straighten me out here. 6 years was to long but you've run them for 15+ years? I think age has much much to do with it than miles, but that's just my humble little opinion.

Using your 50,000 mile figure I would be installing my 4th set of hoses!

Would you run a 15 year old tire just because it was new?

Sure Cliff... I'd rather have the 15 year old hoses from the Arkansas widow than the three year old hoses from the Houston cabbie  :)

To add to the community database, my 2010 with 48k miles just recently started to leak of coolant (couple of drops a day). Will be changing all the hoses soon.

When it becomes more than a couple of drops replace your water pump.   :)     I had a 2010 zx14 that started to lose coolant and I tightened all my hose connections, then it started to lose more and I figured out it was my water pump.

I looked close at the replacement cost from Samco and OEM and was surprised that if you buy OEM hose for every one that comes with the aftermarket kit it really was not that much more.   If you buy the hoses that are not custom bent from bulk then you can save more.  OEM cost for the small drain hoses is redic.
