How old are your coolant hoses??
 
I've got a 93 GSXR750, 17,xxx miles that still has the original coolant hoses. Shop manual says to replace them every 4 years. They still look and feel like new, not soft or rigid. Does anyone think it's a good idea to replace them or am I worrying about nothing again?

I don't think I've ever heard of a hose blowing on a bike. If they're not cracking or bulging they're probably OK.

Green coolant erodes hoses from the inside. If you wait until they start to swell, you take the chance of catastrophic failure, and unlike a car, there's very little keeping the hot (now boiling, with the pressure removed) coolant from scalding your legs. With mesh gear, it could run down into your boots and absolutely destroy your feet before you could get stopped and get them off.

If the recommended replacement interval is every four years, you may want to pay attention to that.

While replacing hoses every 4 years sounds excessive to me, I would definitely want to replace them before they become NLA from the OEM or aftermarket!

I checked today into this today..
aftermarket is not a choice anymore. OEM is available but the prices are down right stupid. About $140 for a small set of about 6 hoses.

I see your point :deal

Sounds about right these days. Six coolant hoses on my car cost me almost $200 recently.

When I got my '61 boat in '97 it still had the original hoses on it. I replaced them in '98 and they are still on there.
The '00 KLR has all factory hoses (except from brake that went SS a decade ago). They have an aggressive replacement plan, something like every 2 years.

I still have the original hoses on my 81 Silverwing.

The hoses on many bikes can be made by cutting up common hoses from the local auto parts store.

I blew a coolant tube on my concours a few years ago on a trip. It was very inconvenient. I put a piece from Napa in there for the ride home and then replaced them all. Of course the hose that blew was the hardest to get to and required removal of a lot of stuff. The bike was 13 years old at the time. My 1999 KLR still has the original hoses and they still look good. If one of those blows it will be much easier to replace than the concours.

I swapped all the original hoses on my ZRX @ 5X000 miles.

I use this for commute and didn't want to chance it. yes it was expensive about $65 for 4-5 mostly very short hoses.

In 20+ years of riding and professional wrenching, I've never seen a coolant hose fail without giving warning. They swell, they get hard and brittle, they leak. They don't just one day split down the middle. Keep and eye on em and you'll be fine.

Samco. Not cheap but quality never is. Replace them.

I replaced the hoses on my '01 KTM 640 when I noticed the anti freeze was discolored due to the original hoses deteriorating from the inside out with ASI Silicone hoses.

Hoses will last longer with regular coolant changes.
